Project Title: LUST Site Investigation and Corrective Action, Roosevelt School District #66, ADEQ Facility ID #0-004192, ADEQ LUST #5850.01, Phoenix, AZ

Roosevelt School District (RSD) contracted Matrix New World Engineering (Matrix) to perform site assessment activities in

2021 through 2023 at the RSD Maintenance Facility and bus yard in Phoenix, Arizona. The scope of work included site characterization and soil remediation and included the following Scope of Work items:

• Drilling and soil sampling of four soil borings to determine the vertical and lateral extent of soil impacted by a release from the former underground storage tank (UST) system. Laboratory analysis of soil samples demonstrated the extent of soil impacted by various petroleum volatile organic compounds (VOC) was adequately defined.

• Installation and sampling of six groundwater monitoring wells to define the source area groundwater conditions and lateral extent of VOC impact to groundwater. Groundwater monitoring and sampling laboratory analytical results defined the lateral extent of impacted groundwater.

• Collection of soil vapor samples at the release source area to assess the potential for intrusion of VOC vapors into current and hypothetical site buildings and determine vapor intrusion risks. Results demonstrated the vapor intrusion exposure pathway was incomplete.

• Installation of soil vapor extraction (SVE) wells and operation of a mobile SVE system to remove residual VOC concentrations from the vadose zone and eliminate the potential for leaching of additional VOCs to groundwater. The SVE system operated for 120 days and removed approximately 24,000 pounds of VOC (e.g., 200 pounds per day; equivalent to 3,800 gallons of gasoline).

• Confirmation soil sampling to determine post-SVE soil conditions and assess the leaching potential of residual VOC to groundwater. The evaluation determined VOC concentrations in soil were reduced below applicable ADEQ Soil

Remediation Levels (SRL) and calculated Groundwater Protection Levels (GPL), which are protective of groundwater.

Timeline: The work was completed July 2021 – November 2023 (> 2 years).

Outcome: Complete characterization of soil and groundwater impacted by the gasoline release. Soil remediation sufficient to require no further action to eliminate vapor intrusion risk and the potential for leaching to groundwater.

Project Title: Well RW-3 HydroPunch® Investigation, Ken McDonald Golf Course, City of Tempe, AZ

Matrix was contracted by the City of Tempe (City) to provide professional services to oversee drilling and sampling at four soil borings (RW-3A, RW-3B, RW-3C, RW-3D) on the City’s Ken McDonald Golf Course (KMGC). The soil borings and proposed recharge wells were designed to support the Kyrene Water Reclamation Plant (KWRP) which is authorized to operate at an annual flow of 9.0 million gallons per day (MGD) in accordance with the Facility’s Aquifer Protection Permit (APP). The drilling and sampling investigation was conducted to: 1) evaluate potential future recharge well locations, including candidate locations for recharge well RW-3, and 2) determine the absence or presence of 1,1-dichloroethene (1,1-DCE) contamination believed to be associated with the Former Capital Casings (FCC) Water Quality Assurance Revolving Fund (WQARF) Site.

Sonic drilling methodologies were chosen to provide a detailed profile of the subsurface stratigraphy. The groundwater sampling strategy included collecting discrete groundwater samples using a HydroPunch® sampling tool at pre-determined intervals in the aquifer to a target depth of 430 ft bgs. Twelve samples were collected from each borehole. All groundwater samples were analyzed for TDS, fluoride, nitrate, total arsenic and chromium, and VOCs. Samples collected at depths of 95, 150, 220, 290, and 370 ft bgs were also submitted for analysis of PFAS.

Timeline: The work was completed January – June 2022 (6 months).

Outcome: 1) The most favorable locations for new recharge wells were identified based on a cumulative score ranking available aquifer thickness and groundwater quality conditions. 2) Concentrations of 1,1-DCE were detected at various depths in one of the four borings. 3) Concentrations of PFOA and PFOS were detected in all samples analyzed. In all soil borings, the combined PFOA plus PFOS results were less than the health advisory level (HAL) of 70 ng/L. Generally, the highest concentrations of combined PFOA and PFOS occur in the upper portion of the Salt River Deposits at depths of 95 to 150 ft bgs.

Project Title: In Situ Bioremediation Evaluation of Solvents and 1,4-Dioxane in Groundwater, Horsham, PA

Matrix New World Engineering (Matrix) personnel evaluated various in situ bioremediation and chemical approaches for degradation of chlorinated solvents (PCE, TCE, cis-1,2-DCE, vinyl chloride) and 1,4-dioxane in groundwater and sediments that had existed at a former industrial site for more than 40 years. Matrix prepared work plans, performed groundwater and soil sampling, conducted fingerprinting analyses to evaluate various sources, and installed Bio-Traps with various carbon sources and bioaugmentation options to use in the design of the full-scale source treatment system.

Matrix personnel worked with regulators at the Pennsylvania Department of Environmental Protection to get approval for the system. An in situ bioremediation system for the source zone, which includes fractured bedrock, was installed. The in situ bioremediation (ISB) system includes two recirculation wells that were injected with quick-release and slow-release carbon source biostimulation amendments, a buffer to maintain optimum pH conditions and a bioaugmentation culture

(Dehalococcoides) to promote complete biodegradation of the chlorinated ethenes to the non-harmful compound ethene. This project also involved the injection of two new microbes, Pseudonocardia dioxanivorans CB1190 and 1,4-DStroyer, which are capable of biodegrading 1,4-dioxane at concentrations greater than 3 milligrams per liter under aerobic conditions.

Timeline: The work was completed September 2021 – October 2023 (injections completed).

Outcome: In less than two years, there has been more than a three-order magnitude decrease in the concentration of chlorinated ethenes in groundwater. More than a 90% reduction in 1,2-dioxane was observed in two years.

Project Title: Groundwater and Soil Vapor Monitoring, O&M of Remediation Systems, PGAN Superfund Site, Goodyear, AZ

In 1981, groundwater within and adjacent to a former Unidynamics Phoenix, Inc. facility located in Goodyear, Arizona was discovered as contaminated with trichloroethylene (TCE) and perchlorate. The Site contained approximately 3 square miles of contaminated groundwater, originating from the facility’s historical manufacturing activities, and was eventually designated as the Phoenix-Goodyear Airport-North (PGAN) Superfund Site.

For PGAN, Matrix managed daily operation and maintenance of five groundwater treatment systems (GTS) and one soil vapor extraction (SVE) system, focused on source area remediation. The combined instantaneous flow rate for the groundwater treatment systems was 4,700 gallons per minute utilizing 19 extraction wells. Treated groundwater was discharged for beneficial reuse to an irrigation canal, golf course pond, used for irrigation of a municipal park, or conveyed to up to 14 injection wells.

Matrix completed engineering design and provided construction oversight for treatment system construction, upgrades, and optimization.

For more than a decade, Matrix performed monthly and quarterly groundwater sampling activities, including sampling of 110+ groundwater sampling points, 60+ soil vapor points, and sampling of the GTS and SVE systems. Matrix also maintained and managed the project database, including analytical results from all sampling points, well construction details, and system data.

Matrix used state-of-the-art 3D modeling techniques and ArcGIS Desktop / Spatial Analyst to depict the horizontal and vertical extent of contaminant mass, groundwater flow and contaminant transport to maximize operation of wells for plume control / containment and to identify strategic locations for additional monitoring locations.

Timeline: Matrix’s work on this project was completed January 2009 – February 2024 (15-year tenure).

Outcomes:

➢ TCE groundwater plumes defined, contained, and reduced by expanding groundwater monitor wells program, treatment system installations/modifications, and extraction/injection well network expansions.

➢ Maintained groundwater treatment system uptimes at 95% goal.

➢ Completed soil vapor extraction (SVE) remedy, rebound soil vapor monitoring, and decommissioned SVE equipment.

➢ Treated groundwater is used for beneficial reuse in Roosevelt Irrigation District and City of Goodyear; as a heat exchanger for St. Thomas Aquinas church & school’s HVAC system; and recharging the local aquifer system.
