Groundwater Exploration and Development
The company has been hired by numerous land owners and developers to test groundwater production, or improve groundwater production in existing wells. The work usually includes geologic mapping, reviewing well production records, the installation of water production test wells, or repairs to existing wells. Pump tests are performed to evaluate aquifer properties, and water quality samples are collected to evaluate water treatment options and raw freshwater quality. Depending upon the uses, water budgets and developed, and water systems are designed predicated upon the use of the water supply. The company has provided these services from Santa Barbara to Siskiyou County, California.

DHS 97-005 Permit for the Use of Impaired Drinking Water
The company was awarded a contract to prepare 97-005 Permit Documentation to allow the United States Department of Agriculture to treat and utilize MTBE contaminated groundwater for drinking water in northern California. The work required the investigation and remediation of gasoline that had migrated into a water supply aquifer; the design and install a new public water supply wells; and the design, build and operation of a dual hydraulic control and vapor extraction system. The company represented the government in litigation, and helped recover approximately $850K from an oil company responsible for the pollution.

MTBE Contaminated Groundwater
The company has been hired by numerous oil companies to respond to Regional Water Quality Control Board directives to investigate the source and magnitude of, and to remediate MTBE contaminated aquifers. Almost all of the aquifers protected by the remedial actions have involved municipal water supply aquifers at various locations in northern and central California. The work elements include permitting, sensitive receptor surveys, the installation of soil borings and monitor wells, the interpretation of the magnitude and extent of contamination, the installation of alternate water supply wells; the design, build and operation of hydraulic control lines, vapor extraction systems, air sparging systems, or removal actions. The work is almost always conducted under the budgets and limitations established by the RWQCB and State Cleanup Fund.

PCE and TCE Contaminated Groundwater
The company has been hired by numerous PRPs to investigate and mitigate the effects of chlorinated solvents and dry cleaning fluids in groundwater. In almost all cases, the work has involved the protection of municipal water supply aquifers and city or municipal water supply wells. The work has been performed for insurance companies, private parties involved in litigation, as part of court ordered private CERCLA corrective actions, and under NCP guidance. The company has designed, built and operated hydraulic control lines at these Sites, one of which is on the shoreline of Lake Tahoe, California.

E. Coli Contaminated Groundwater
The company has been contracted to evaluate the source of E.Coli contamination in water supply systems for restaurants, private water supply wells, public water supply wells, and in water processing streams for food processors. The work usually involves sewer line investigations and leak surveys, septic leach field investigations, sampling soil and groundwater in the areas of potential sources, and evaluating overspills and cleanout history. In one important case, the company provided litigation support for an insurance carrier in U.S. Federal Court, which was responsible for shutting in a contaminated water supply well.

Nitrate Contaminated Groundwater
The company was hired by a major manufacturer of explosives to evaluate the magnitude and extent of nitrate in groundwater at a manufacturing facility in the western united states. The work involved the installation of soil borings and monitor wells, subsurface geologic and water quality mapping, chemical testing of soil and groundwater samples, and preparation of problem assessment and corrective action plans.

Waste Water Injection and Aquifer Evaluation
The company was contracted by an oil field technology company to evaluate water quality in deep aquifers that had accidentally received oil field waste water injection in Santa Maria County, California. The work includes the drilling of several deep test borings, geophysical logging, chemical testing and evaluation of waste water quality, aquifer testing, formation evaluation using SP, Gamma, shallow and deep resistivity, Bulk and sediment density using FDC/CNL methods, and the evaluation of aquifers for the receipt of injected brine water. The work was conducted to the satisfaction of the RWQCB, eventually leading to closure of all injection locations.

Construction Dewatering
The company has been contracted to evaluate the cost effectiveness of construction dewatering systems, and water damages caused by leaking municipal water supplies for underground storage tank systems, vaults, subterranean structures, and irrigation water supply lines. The company has assisted insurance companies and private parties settle major claim differences in arbitration at JAMS. In a most important case, the company represented a major public insurance broker verses a large international bank, which removed a vaulted underground storage tank at a data processing center. A settlement was reached which substantially reduced the insurance company¹s exposure by approximately $10.0M.

Landfill Cap Design and Build
The company was hired by a major wine producer to design and build a cap for a landfill at a northern California manufacturing facilty. The work involved the collection of geotechnical and environmental soil samples, the physical testing of soil samples, and the design of a RCRA style cap. The company managed the installation of the cap, and oversaw the closure of the facility.

Hazardous Waste Reclassification
The company was contracted by a California Oil Company to reclassify hazardous wastes as designated wastes using CAL EPA reporting and testing procedures. A previous consultant had reported the results of flash test results to the Placer County Health Department. The PCHD classified the materials as hazardous waste, and ordered the removal of the materials at a cost that would have exceeded $1.5M. A contentious investigation was conducted by Cal EPA, PCHD and the district attorneys office. After further evaluation, the materials were reclassified, saving the Oil Company approximately $1.25M.

Sewer Line Corridor Evaluations
The company has been contracted by three different municipal sewer districts to conduct environmental evaluations along planned sewer line corridors in Contra Costa and Alameda counties. The work involved the installation of soil borings, monitor wells, soil and water quality testing, the coordination of the removal of hazardous wastes, and subcontractor management.

Hydrocarbon Contamination in Sewer Lines
The company has been contracted to evaluate the source of hydrocarbons in sewer lines by the local sanitary sewer district. The work involves the collection and testing of soil and groundwater samples from along the sewer lines, the evaluation of sewer line leakage and construction, and preparation of health and safety plans to abate explosive conditions, and prepare monitoring and hazardous materials removal action workplans. The company has assisted with the identification of sources of contamination and evaluation of the effectiveness of remedial actions.

Environmental Site Assessments for Property Transfers
The company has been contracted by numerous private and commercial parties the last 15 years to conduct Phase I and Phase II Site assessments for property transfers. The work, conducted to ASTM standards, has been conducted for banks, lending institutions, automobile dealers, oil companies, insurance companies, major food distributors, and silicon chip manufacturers. In one case, the company was contracted to evaluate the transfer of a piece of property from the Lawrence Livermore National Laboratory to the City of Pleasanton. After reviewing CERCLA reports prepared for the LLNL, the company was able to assist the City of Livermore with its receipt of the property. The land has subsequently turned the property into a park.

Underground Storage Tank Investigations and Remediation
The company has been hired by numerous oil companies, land owners, small business owners, law firms, and the United States government to evaluate and remediate leaking underground storage tanks. The company provides all the services necessary to conduct this work, including preparation of workplans, permitting, health and safety, subcontractor management, installation of soil borings and monitor wells, water quality monitoring, subsurface geologic and water quality evaluations; aquifer and vapor extraction testing, chemical oxidant applications, and designs, builds and operates dual vapor and groundwater extraction systems. Company personnel have literally conducted this work on hundreds of underground storage tank sites the past 25 years, and have obtained agency closure on numerous sites.

Leaking Irrigation Line Water Damage
The company was hired to assist the local water supply district evaluate the source and damage caused by leaking water supply lines beneath a shopping mall in northern California. The water district was sued by a land owner for allegedly operating a leaking water supply system, which damaged the foundation of the shopping center. The company provided expert witness testimony and assisted with the reduction of claims laid against the insurance carrier representing the water district.
