Roberts, Manager ADEQ/Waste Programs Division/Remedial Projects A.R.S. §§49-281 to 49-296 (602) 771-7655 EVA0305.SUB This annual report has been prepared pursuant to HB 2781, Laws 2007, Chapter 255 making appropriations for the different departments of the state, for state institutions and for public schools; providing for certain reporting requirements. HB2781 requires that a report on the Water Quality Assurance Revolving Fund (WQARF) along with specific site budgets for FY2008 be submitted to the joint legislative budget committee (JLBC) members and to the Director of the JLBC by September 1, 2008. The FY2009 WQARF site budgets and FY2009 WQARF program projected budget can be found in Appendix 1. WQARF PROGRAM OVERVIEW Program Description Through the WQARF Program, the Arizona Department of Environmental Quality (ADEQ) identifies, assesses, and cleans up soil and groundwater that is contaminated with hazardous substances. The program conducts these efforts state-wide using state funds and also oversees privately-funded cleanup efforts. Responsible parties are identified and notified, and then legal and technical evidence is gathered for recovery of ADEQ’s costs and enforcement of cleanup requirements. WQARF was created under the Environmental Quality Act of 1986 to support clean up efforts in the state. The program underwent significant revisions as a result of what is known as the WQARF Reform Legislation of 1997 (Laws 1997, Chapter 287). The major provisions of the WQARF Reform Legislation are as follows: Proportionate Liability – Liability for the costs of the cleanup of contaminated sites is proportionate, rather than joint. Cleanup costs are proportionately allocated among responsible parties using a process defined in statute. Identification of responsible parties and the allocation of cleanup costs are the responsibilities of ADEQ. A non-judicial allocation hearing process is available for the resolution of disputes regarding ADEQ’s allocations. Program Funding – The adoption of a proportionate liability system increased the need for adequate and dedicated program funding. To ensure that WQARF program funding is sufficient to administer the program and to pay allocated, uncollectible orphan shares, the WQARF reform legislation provided for an annual $18 million expenditure. The fund is dependent upon the direct transfer of funds from legislative appropriations, corporate income tax, cost recovery, and special fees. ADEQ WQARF Annual Report, Page 3 Site Prioritization – Sites are to be prioritized with a greater emphasis on risk to human health. The statute provides a process to score sites according to actual and potential exposure to hazardous substances. This score and other factors are considered when prioritizing the expenditure of WQARF funds. Cleanup Methods and Goals – WQARF Reform provided for increased flexibility in the selection of groundwater cleanup methods and levels. ADEQ has adopted remedy selection rules that incorporate analysis of a range of cleanup options, from remediation of the contamination to no action. Significantly, the statute clarifies that the cleanup need not always result in the achievement of drinking water standards within the aquifer. Community Involvement – Enhanced community involvement is required for at all stages of the cleanup process. The statute establishes a process to encourage active community involvement, including provisions for notices, community involvement plans, and the formation of a community advisory board for each site. Settlements – Prompt settlements as an alternative to litigation are encouraged. ADEQ is authorized to offer a 25 percent discount to responsible parties who settle after the Department provides notice to them of their proportionate share of liability. In addition to the costs of administering the program and conducting remedial actions, A.R.S. § 49-282(E) authorizes WQARF funding for other uses. Descriptions of the following uses/programs and their accomplishments are discussed later in the report: • Emergency Response Program • Water Quality Monitoring Program • State matching monies or to meet other obligations prescribed by § 104 of CERCLA • Well Inspections and Approval Program at the Arizona Department of Water Resources • Risk Assessment Program at the Arizona Department of Health Services Program Process Overview Typically, upon addition of a site to the WQARF Registry, numerous investigative, planning, community involvement, risk assessment, and legal steps must be executed before a cleanup can begin. Exceptions to this sequence of steps are made when early response actions are taken to protect human health or the environment. The WQARF Remedy Selection Process is outlined in Appendix 2. Once in the WQARF program, sites undergo a remedial investigation/feasibility study (RI/FS). An RI/FS is a two-phase investigation conducted by ADEQ or interested parties to investigate the ADEQ WQARF Annual Report, Page 4 scope of contamination and determine the alternatives for remediation. During the RI/FS, extensive technical information, that may include soil and groundwater sampling and analysis of both the site property and adjoining areas that may also be contaminated, is collected. The objective of the RI/FS is to gather sufficient data to evaluate and select the most appropriate cleanup alternative for the site. Concurrently, ADEQ is required at most sites to conduct an extensive search to identify potentially responsible parties (PRPs). During and following the RI/FS, legal negotiations may be undertaken in response to a party’s request to settle liability early and to gain access to private properties for investigation or cleanup implementation. Community involvement is emphasized during investigations, prior to development of the proposed remedial action plan (PRAP), and at other times as appropriate depending on site specific issues. These community involvement efforts may include the formation of community advisory boards (CABs) to assist in relaying information and concerns between the public, ADEQ, and interested parties. The Arizona Department of Health Services (ADHS) may also provide input to the remedial investigation through evaluation of potential risks to human health. Once the FS is completed and cleanup alternatives are identified, a PRAP is developed and is made available for public comment. A record of decision (ROD) documenting the selected cleanup alternative is finalized, followed by a liability allocation process in which past and future remediation costs are distributed among responsible parties. After the ROD is finalized, extensive remedial system design development and review must be undertaken. Several months to several years may be needed to finalize a design, construct the remedy, and start the actual cleanup. After the remedial system is constructed, operation and maintenance may be conducted as appropriate to the remedy. Because formal investigation and remediation can take many years, ADEQ developed a process to address contamination that requires immediate action. The early response action process can be used at any time prior to the implementation of a final remedy. Early response actions may be taken to address any of the following conditions: • To mitigate an immediate threat to public health or the environment; • To clean up a source of contamination; • To prevent migration of contamination to uncontaminated areas; or • To provide drinking water to residents whose drinking water supply has been contaminated. ADEQ WQARF Annual Report, Page 5 MAJOR ISSUES & ACCOMPLISHMENTS FOR FY 2008 WQARF Funding As described earlier in the report, ADEQ’s ability to administer and implement the WQARF Program depends on $18 million per year in dedicated funding. A.R.S. § 49-282(B) specifies that $15 million of that $18 million is transferred from the Corporate Income Tax. However, due to budget shortfalls, the WQARF Program received a combined total of $56 million from the Corporate Income Tax for Fiscal Years 2002 through 2007. Without budget shortfalls, ADEQ would have received a total of $90 million from the Corporate Income Tax for fiscal years 2002 through 2007. In FY2007, the program received full Corporate Income Tax funding. This is the first time in seven fiscal years this has occurred. As a result, ADEQ exceeded the $18 million revenue target for the first time and was able to prepare for early response actions at the Klondyke and Cooper and Commerce sites. The program was also able to complete several paramount achievements such as the first consent order at a WQARF site, first environmental lien, first record of decision (ROD), and the first declaration of environmental use restriction (DEUR). During FY2008 the program once again experienced a $2 million reduction in Corporate Income Tax transfer. The WQARF program’s fund balance in FY2008 was additionally reduced by a $3 million legislated fund transfer. This $5 million reduction to available resources negatively impacts the program’s ability to continue progress at some sites.

In FY2008, the WQARF Program continued operation and maintenance (O&M) on numerous ERAs that were initiated in prior years. In FY2008, the WQARF Program initiated the following ERAs: Central & Camelback: ADEQ began operation of a soil vapor extraction (SVE) system at the former Maroney’s Dry Cleaning facility in November 2007 to remediate tetrachloroethene (PCE) contamination present in the subsurface soils at this site. As of June 30, 2008, the system removed approximately 1,200 pounds of volatile organic compounds (primarily PCE) from the soil. In addition to this ERA, ADEQ continues to operate the groundwater pump and treat system ERA at this site. The system treats approximately 130,000 gallons of groundwater per day. Klondyke Tailings: In response to significant flooding in July 2006, ADEQ conducted a floodplain analysis which revealed that the “upstream” tailings pile was within, and subject to erosion from, the 25-, 50- and 100- year flood events on Aravaipa Creek. ADEQ initiated and completed an ERA of the upper tailings pile in FY08. The ERA completed in June 2008 consisted of consolidation, installation of erosion protection, and capping of the upper tailings pile. Protection of Aravaipa Creek is important as there are seven native species present in The Nature Conservancy Aravaipa Canyon Preserve, including the loach minnow, spikedace, sonoran sucker, desert sucker, speckled dace, longfin dace and roundtail chub. The loach minnow and spikedace are federally-listed Threatened Species and the remainder are Species of Concern. The preserve is located only two miles downstream of the tailing piles. WQARF Preliminary Investigation Remedial Actions Nogales Grand Avenue (not yet on WQARF registry): In response to PCE concentrations above aquifer water quality standards detected in Valle Verde’s supply wells, ADEQ developed a well inventory of the area, and approximately 30 public and private wells were sampled in December 2007. Concentrations ranged from non-detect to 21 μg/L PCE. Additionally, ADEQ is coordinating with Valle Verde Water Company to design and build wellhead treatment systems on two Valle Verde wells to treat PCE contaminated groundwater. Construction of this system has begun. In parallel to this effort, ADEQ and the City of Nogales reached an agreement for ADEQ to fund building interconnecting pipelines between Valle Verde’s water system and the City’s water system to act as an emergency backup. Main Street and Kofa (not yet on WQARF registry): ADEQ installed five soil vapor extraction ADEQ WQARF Annual Report, Page 7 wells, 19 ozone sparging wells and 20 dual-phase extraction wells. The wells are part of a remediation system that uses three different types of technologies. Due to the site specific technical challenges associated with the area, a remediation system was developed that would be able to clean up contaminants that are trapped in the vadose zone. ADEQ initiated start up of the SVE system in December 2007. Approximately 30,000 pounds (lbs) of volatile organic compounds (VOCs) were removed from the subsurface soils in FY08. ADEQ initiated start up of the dual phase system in February 2008 and approximately 162,000 gallons of water has been processed and 15 gallons of free product recovered. ADEQ initiated the ozone air sparging system in April 2008. Interim Remedial Actions (IRA) IRAs are taken at a registry site to protect water supply wells, provide alternative water supplies, replace wells, or for water treatment. ADEQ has been working with the Salt River Project (SRP), Flowing Wells Irrigation District (FWID) and the Tucson Metropolitan Domestic Water Improvement District to implement interim remedial actions (IRAs) at the East Central Phoenix – 48th Street and Indian School, Miracle Mile, and Shannon Road/El Camino del Cerro WQARF sites, respectively. East Central Phoenix – 48th Street and Indian School Road: As part of an agreement and funding from ADEQ, SRP is managing remediation activities at the site in order to protect a down-gradient SRP production well. A SVE system is in place and, approximately 295 pounds of PCE have been removed since system start-up in February 2006. Miracle Mile: ADEQ entered into a cooperative agreement with FWID to provide wellhead treatment for the removal of VOCs at two FWID production wells. The treatment system was jointly designed and constructed by ADEQ and FWID and incorporated into FWID’s arsenic treatment system. The 900 gallon per minute (gpm) system was put into operation in January 2007 and treated approximately 300 million gallons of water in FY08. Shannon Road/El Camino del Cerro: Through a cooperative agreement with Metropolitan Domestic Water Irrigation District, ADEQ has been funding the wellhead treatment and operation and maintenance costs associated with a system designed to treat VOC contaminated groundwater. Approximately 175 million gallons of water were treated and 44 pound of VOCs removed by this system in FY08. Operation & Maintenance (O&M) ADEQ continues to conduct or fund operation and maintenance (O&M) activities of the following groundwater pump and treat, soil cap maintenance, and soil vapor extraction systems: • 7th Street and Arizona Avenue (SVE) ADEQ WQARF Annual Report, Page 8 • • • • • • • • Broadway and Pantano (groundwater pump and treat) Central Avenue and Camelback Road (groundwater pump and treat and SVE system) East Central Phoenix – 32nd Street and Indian School Road (SVE) Klondyke Tailings (upper tailings cap protection) Payson PCE (groundwater pump and treat) Tyson Wash (groundwater pump and treat) Vulture Mill (soil cap maintenance) Main Street and Kofa [groundwater pump and treat (dual-phase extraction), air sparge/SVE] Remedial Investigations (RI) ADEQ initiated a remedial investigation at the following site in FY08: • Central and Camelback Proposed Remedial Action Plans (PRAP) • • Tyson Wash: ADEQ issued the PRAP for public comment on June 4, 2008.

FY 2008 Activities and Accomplishments The Emergency Response Unit (ERU) was notified of 219 incidents, 20 of which required onscene response actions. The ERU was also involved in several drills and exercises including TOPOFF 4 which was the largest Homeland Security exercise ever held. This exercise involved more than 15,000 participants from federal, state, territorial and local governments, as well as private sector and non-government organizations. In addition to Arizona, the state of Oregon and the U.S. Territory of Guam took part in this four-day exercise. The ERU provided support during the Super Bowl XLII. Significant emergency response actions include: Response to Transportation Accident: At the request of the Department of Public Safety, ERU personnel responded to a diesel fuel tanker accident just east of the Colorado River at the intersection of Highways 68 and 95 in Bullhead City. A tanker carrying approximately 6,000 gallons of diesel lost control while traveling east on Nevada Highway 163. After striking a vehicle on the Nevada side of the Colorado River, the vehicle continued on across the bridge and struck ADEQ WQARF Annual Report, Page 16 two additional vehicles on the Arizona side before the tanker rolled over at the Hwy 68/95 intersection. It was estimated that 4,000 gallons of diesel fuel were released from the tanker as a result of this accident. Actions taken by response personnel at this incident prevented any of this fuel from entering the Colorado River. Response to Large Transformer Fire: At the request off the Phoenix Fire Department, ERU personnel responded to a large electrical transformer fire located in a substation just south of Happy Valley Road and the Loop 303. Large volumes of heavy smoke generated by the fire prompted a response by the ADEQ Hazardous Air Emergency Response (HEAR) team. Public utilities officials asked that the fire be allowed to burn itself out because the foam and water needed to extinguish the fire could possibly damage the power grid. On-site ADEQ personnel agreed with that recommendation and the transformer was allowed to burn. It is estimated that between 8,000 and 20,000 gallons of mineral oil were burned during this fire. A.R.S. 49-282(E) (11) also provides for reimbursement to political subdivisions for cost incurred in response to a release or a threat of a release of a hazardous substance or pollutant that presents an immediate and substantial endangerment to the public health or the environment. There were no new applications received in FY 2008. WATER QUALITY ASSESSMENT AND MANAGEMENT PROGRAM Pursuant to A.R.S. § 49-282(E)(3), WQARF monies are used for the costs of monitoring, assessing, identifying, locating, and evaluating the degradation, destruction, loss of or threat to the waters of the state resulting from a release of a hazardous substance to the environment. Pursuant to A.R.S. § 49-282(E)(6), WQARF monies are also used for the costs of the water quality monitoring program described in A.R.S. § 49-225. A description of Water Quality Assessment and Management Program FY 2008 activities and accomplishments can be found in Appendix 6. WELL INSPECTIONS AND APPROVAL PROGRAM Pursuant to A.R.S. 282(E)(12) WQARF monies are used to fund the Arizona Department of Water Resources to conduct well inspections and remedial actions, and for the review and approval of well construction design necessary to prevent vertical cross-contamination. The FY 2008 accomplishments of the Well Inspections and Approval Program can be found in Appendix 7. RISK ASSESSMENT PROGRAM Pursuant to A.R.S. 282(E)(15) WQARF monies are used to fund the Arizona Department of Health Services to assess and evaluate the effect of a release or a threatened release of hazardous substances to the public health, welfare, or the environment. The FY 2008 accomplishments of the Risk Assessment Program can be found in Appendix 8.

The Registry includes those sites within the state that may pose risk to public health, welfare or the environment from the release of hazardous substances and for which there is current or planned investigation and cleanup. There are 35 sites on the WQARF Registry: 22 in Maricopa County, 7 in Pima County, 3 in Gila County, 1 in Graham County, 1 in La Paz County, and 1 in Yuma County Sites on the Registry are scored based in part upon the type of contamination present, the location of the contamination, and the number of people that may be affected. The maximum score a site may receive is 120. Scores are used to help determine relative risk from the site and do not necessarily mean that there is direct exposure of contaminants. Whether the site is currently being remediated or is being investigated, ADEQ takes steps to identify the contamination and to prevent exposure. The Registry and additional information regarding these sites is available on ADEQ's Web site at http://www.azdeq.gov/environ/waste/sps/program.html. With a 24 hour notice, an appointment to review the Registry and additional information is available Monday through Friday from 8:30 a.m. to 4:30 p.m., at ADEQ, Records Management Center, 1110 W.

The site is located in Phoenix and is bounded to the north by Berridge Lane, to the south by Bethany Home Road, to the east by 6th Avenue, to the west by 8th Avenue and includes the 2.6-acre former shopping center that housed a dry cleaning facility. ADEQ initiated an Early Response Action (ERA) Evaluation on the site in October 2004 to collect data necessary to characterize the source area of tetrachloroethene (PCE) contamination below the site. The ERA Evaluation consisted of drilling 10 soil borings and the installation of five soil vapor extraction wells and two groundwater monitor wells at the site. Additional off-site groundwater monitor wells were installed in 2005. Based on the results of the ERA Evaluation, soil vapor extraction (SVE) was chosen for remediation of PCE contaminated soil beneath the site. The SVE system began operations in June 2005 and the SVE system was shut down in January 2006 after recovering approximately 380 pounds of volatile organic compounds. Confirmation soil samples confirmed that the source area soils had been successfully remediated to levels that are below ADEQ Soil Remediation Levels and Groundwater Protection Levels. Remediation strategies for PCE contaminated groundwater are currently being evaluated and quarterly groundwater monitoring is on-going. There are no drinking water production wells within the confines of the site, but ADEQ is closely monitoring the movement of the groundwater plume. Two Salt River Project irrigation wells near the site have been tested, and concentrations of PCE were not detected above the regulatory standard. Contaminants of concern at the site include PCE and trichloroethene (TCE). 7th Street and Arizona Avenue – This site was placed on the WQARF Registry in April 2000 and has a score of 40. The site is located in downtown Tucson at approximately 1/3 mile north of Broadway Boulevard and approximately 3/4 mile east of Interstate 10. The site boundary is a northwest-trending area extending approximately 1,200 feet from the former Oliver’s Cleaners facility at 300 E. 7th St. to approximately 150 feet north of 6th Street and approximately 100 feet east of 7th Avenue. ADEQ is currently operating a soil vapor extraction (SVE) system as an early response action for the site. To date, over 700 pounds of volatile organic compounds have been recovered by the SVE system. Additional monitoring wells are scheduled to be installed and groundwater monitoring activities are on-going. No drinking water wells have been impacted by the contamination from the site. The remedial investigation has not been initiated. Contaminants of concern at the site include tetrachloroethene (PCE), trichloroethene (TCE), and cis-1,2-dichloroethene (cis-1,2-DCE). 2 Arizona Department of Environmental Quality Water Quality Assurance Revolving Fund 2008 Annual Registry Report ____________________________________________________________________________ 16th Street and Camelback Road – This site was placed on the WQARF Registry in April 1999 and has a score of 23. The site is located in Phoenix and is bounded approximately by Medlock Drive to the north, Highland Avenue to the south, 17th Street to the east and 14th Place to the west. Based on the results of an Early Response Action Evaluation conducted in 2003, ADEQ determined that soil vapor extraction was not a feasible remedy for the site. ADEQ is currently evaluating other potential remedies for the site, and groundwater monitoring activities are on-going. The remedial investigation has not been initiated. Contaminants of concern at the site include tetrachloroethene (PCE), 1,2-dichloropropane and 1,2dichloroethane (1,2-DCA). 20th Street and Factor Avenue –This site was placed on the WQARF Registry in March 2000 and has a score of 31. The site is located in Yuma, approximately 1/2 mile south of 16th Street and approximately 3/4 mile east of 4th Avenue. In 2002, ADEQ conducted a soil removal action and cleaned out sumps and septic tanks at an active facility as part of an early response action. Groundwater monitoring activities are on-going and no drinking water wells have been impacted by the contamination from the site. Contaminants of concern at the site include tetrachloroethene (PCE), trichloroethene (TCE) and cyanide. 56th Street and Earll Drive – This site was placed on the WQARF Registry on June 2, 2004 and has a score of 40. The site is located in Phoenix and bounded to the north by Earll Drive, to the south by McDowell Road, to the east by 56th Street, and to the west by 36th Street. The site was originally investigated as part of the Motorola 52nd Street National Priorities List (NPL) Site. However, groundwater data from both sites indicate that the two trichloroethene (TCE) groundwater contaminant plumes are separate and distinct plumes. Therefore, the site was disassociated from the larger Motorola 52nd Street NPL Site. ADEQ is working cooperatively with a party potentially responsible for the contamination to further evaluate the site and develop a cleanup strategy. An Early Response Action (ERA) Evaluation has been completed, and the working party is currently designing an ERA groundwater pump and treat system. A community advisory board has been established for this site. Contaminants of concern at the site include TCE. Broadway-Pantano – This site was placed on the WQARF Registry in December 1998 and has a score of 57.

This comprehensive report assesses water quality in streams, lakes and groundwater in Arizona’s ten watersheds based on data collected since January 1, 2000. From this assessment, those waters not attaining surface water quality standards and/or designated uses are placed on the CWA 303(d) List of “impaired waters” for further investigation and remediation. (§49-225 & §49-282) • Ambient Surface Water Program: FY08 monitoring focused on the Salt and Verde Watersheds. Approximately 200 samples (50 samples per quarter) were collected from 50 sites. Thirty-four percent of the sites were randomly selected while 66 percent were targeted sites used to fill in data gaps, monitor outstanding Arizona waters, and to monitor sites for reference conditions. The FY09 sample plan has been finalized and focuses efforts in the San Pedro, Santa Cruz, Upper, Middle and Lower Gila watersheds. The Surface Water Section (SWS) continues to fund a Joint Cooperative Agreement with the USGS to sample 11 sites on the large rivers in the state from its gauging stations. Most of the analytical work for this program is performed by the ADHS State Laboratory. Drought continues to significantly impact all surface water monitoring programs. (§49-225) • Lakes Program: FY08 monitoring was conducted on Saguaro Lake, River Reservoir, Becker Lake, Show Low Lake, Soldier’s Annex Lake, Roosevelt Lake, Canyon Lake, Lake Havasu, and Bartlett Lake in support of ongoing studies. The Lakes Program continues to collaborate with the University of Arizona Water Resources Center and the Arizona Game and Fish Department to provide field support in monitoring the Valley drinking water reservoirs (Roosevelt, Apache, Canyon, and Saguaro)(§49-225). The lakes program also sampled 21 lakes throughout Arizona as part of the EPA's National Lake Survey. A lakes classification system, nutrient matrix and implementation procedures have been developed and proposed in the current surface water quality standards rulemaking. These narrative standards, once adopted, will be used in future water quality assessments. (§49-221 & §49-222) • Priority Pollutant sampling program: No new fish consumption advisories were issued in FY08. However, fish were collected from several lakes and sampled for mercury in on-going investigations which may lead to future advisories. • Status of ongoing water quality studies (§49-225 & §49-282): Pinto Creek- The proposed 42 ug/L site specific standard (SSS) for dissolved copper is included in the current surface water quality standards rulemaking. It is anticipated that the rulemaking process will be completed in late 2008. Effectiveness monitoring of the Gibson tributary and sites along Pinto Creek indicate that remediation efforts at the Gibson mine have lowered copper loads emanating from the mine by approximately 30%. However, Pinto Creek below the Gibson tributary still exceeds the current, and the proposed standard, with an average concentration of 380 ug/L. Mule Gulch- Modeling efforts are underway to determine site specific standards (SSSs) for copper, zinc, pH, lead, and cadmium applicable to Mule Gulch. Historic smelting operations are a complicating factor that will be addressed. Modeling is expected to be completed in Fall 2008. Any proposed SSSs will be adopted in a future rulemaking process. Queen Creek- The 2007/08 winter storms provided ample runoff for sample collection. Hydrologic modeling is occurring in-house. Data compilation and verification are nearly complete; once completed, the model runs can begin. The TMDL modeling and associated report is anticipated to be finished by the end of calendar year ’08. Lake Mary Regional Mercury TMDLs- (Upper and Lower Lake Mary, Soldier’s, Soldier’s Annex, and Long Lake). Additional watershed soil sampling was completed to determine the appropriate background level of mercury. The model was rerun at the lower soil concentration to determine how methyl mercury levels in the lakes would be affected. The lake models will be further refined to determine how changes in atmospheric contributions directly to the lake will change methyl mercury levels in the lake. Originally walleye were the target fish species on which load reduction calculations were based; however, recent data suggest that walleye are no longer present in all of the lakes. Coordination with AZ Game and Fish is ongoing to resolve this question as a change in target species will affect the TMDL calculations. Alamo Lake- Additional watershed soil sampling was conducted to determine the appropriate natural background levels throughout the watershed. The TMDL model will be rerun to determine how these concentrations affect the loading to the lake. Parker Canyon Lake- Data collection and modeling have been completed. ADEQ is awaiting the draft modeling report to be submitted by the contractor. TMDL completion is anticipated by Spring 2009. Submittal of the Lake Mary Regional, Alamo Lake, and Parker Canyon mercury TMDLs to EPA Region 9 will be delayed until the adoption of the 0.3 mg/kg fish tissue standard, which is included in the upcoming Water Quality Standards rule package. Slide Rock State Park pathogen TMDL phase II – Data analysis and TMDL calculations are anticipated to begin in late Summer 2008. Upper Gila River- Data analysis has been completed and TMDL reports are being drafted. Lower San Pedro- The sample and analysis plan (SAP) is being implemented. Sample collection will continue through the 2008/09 winter season. Santa Cruz River- The Sampling and Analysis Plan (SAP) is near completion. Coordination continues with the Friends of the Santa Cruz and the National Park Service to collect E. coli data and nutrient data along the Santa Cruz River and Nogales Wash Lyman Lake- In-lake sampling and tributary sampling will be completed Summer 2008 if sufficient runoff samples can be collected. Additional lake core analyses are underway to determine near-source mercury contributions. Little Colorado River- Implementation of the Sampling and Analysis Plan is underway with sampling continuing through Summer 2009. Boulder Creek Cleanup Project – Freeport McMoRan has tentatively expressed an interest in accepting the Hillside mine tailings material at their Bagdad facility. ADEQ Waste Program and EPA Region 9 are working on limiting Freeport’s liability should they dispose the material at their facility. Turkey Creek- Effectiveness monitoring has found no exceedances of the total or dissolved copper standards, however total lead still occasionally exceeds statndards. Remediation of the Golden Belt and Golden Turkey mines has been successful in removing copper from Turkey Creek. Tonto Creek- Effectiveness monitoring continues through Summer 2008. Once the recent data has been analyzed, the TMDLs will be revised. Alum Gulch- USFS remediation of the World’s Fair and Humbodlt Canyon mines waste and tailings piles has been completed. Effectiveness monitoring under baseflow conditions indicates that the adit discharges in the watershed continue to degrade water quality. Stormwater sampling has not been completed, but should reflect any improvements from remedial efforts. Rainbow Lake- ADEQ s sampled the lake during the peak productive season in order to apply the proposed Narrative Nutrient Standard for lakes. A local watershed group has installed buffer strips to reduce the amount of nutrients entering the lake from overland flow. Other studies- Atmospheric Deposition of Mercury- An important component of mercury contamination is atmospheric deposition. Prior studies have relied upon national or regional model data extrapolated to Arizona. The SWS established the first Arizona Mercury Deposition Network (MDN) site in April 2006 and continues to operate the site. The MDN collects weekly precipitation composite samples to determine the wet deposition concentration of mercury. Additionally, to help determine the dry deposition rate of mercury, SWS has worked with US EPA Region 9 to deploy their mobile TEKRAN equipment at three sites across the state. Previously collected TEKRAN and MDN data are being analyzed by an EPA contractor to determine local wet and dry deposition rates. Using local deposition rates will increase the strength of mercury TMDLs. Groundwater Monitoring § 49-225 (Water Quality Monitoring) Ambient Groundwater Monitoring – The SWS ambient groundwater program achieved the following in FY08: • Sampling of over 75 wells/springs in Arizona with results provided to well owners • Sampling for the Agua Fria Basin characterization included sampling 46 wells/springs to characterize the groundwater quality of the Agua Fria basin. A draft report on the Agua Fria study will be routed through ADEQ management in September, 2008. • Sampling for the Bill Williams Basin included sampling 67 wells/springs to characterize the groundwater quality of Bill Williams basin. This basin is a huge area that stretches from just outside Prescott to the Colorado River; additional samples will need to be collected to adequately profile the area. • Sampling for the McMullen Valley included sampling 76 wells to characterize the groundwater quality of the McMullen Valley basin. Some of these wells were sampled specifically to examine in depth potential elevated nitrogen concentrations in the Salome area. • Completing final groundwater reports for the Hualapai Valley Basin and the Pinal Active Management Area. • Entering approximately 5,711 water quality results into groundwater water quality database. Pesticide Program § 49-249 (Pesticides) • The pesticide groundwater monitoring program continued its improved frequency and scope in ‘08 to acquire new baseline data for newly-emerging pesticides using the ASDH Laboratory’s modern analytical technology with low detection limits. Well matching data confirmation has been completed, and new results of sampling are being compared to existing database information to establish trends in pesticide concentrations. A list of five “Pesticides of Concern” has been developed based on detections of the active ingredients in Arizona groundwater. The detections are still in very low concentrations (<1 ppb), but ADEQ has initiated preliminary discussions with the Arizona Department of Agriculture and other stakeholders on how to develop Best Management Practices (BMPs) to mitigate or eliminate these detects in groundwater. Plans are in progress to expand groundwater monitoring beyond the vulnerable areas in Yuma and Maricopa counties to similar areas in Cochise and La Paz counties. This may involve future installation of dedicated monitoring wells. • The Pesticide Program continues to maintain an information submittal and review database for the pesticide data call-in program. Seventeen new pesticide active ingredients were added to the database in FY 08. • Implementation of the new rules regarding pesticide registration has been completed. These rules provide for the use of expanded information and newer EPA protocols, modeling, and new science in determining whether a pesticide being registered in Arizona has the potential to leach and pollute groundwater. This streamlining has facilitated the pesticide registration process and the improvement has been noted by stakeholders. Most applications were completed within the approved time frames. Another significant change was removal of the GWPL (“List”) from the rules which allow for timely addition and deletion of chemicals to and from the list as needed. The draft 2008 GWPL was published in the Arizona Administrative Register in July 2008 for public review and comment prior to finalization. The final 2008 List contains 72 active ingredients (3 additions) compared to 69 active ingredients on the 2007 List. The new List takes effect on December 1, 2008. Quality Assurance/Quality Control (QA/QC) Activities • • Served as WQD representative on QA/QC Advisory Committee for the redrafting of the agency’s Quality Management Plan (QMP). The Surface Water Section (SWS) redrafted an integrated and comprehensive Quality Assurance Program Plan (QAPP) that covers SWS monitoring programs. This document was submitted to EPA for approval in June 07.
