DESCRIPTION OF ENVIRONMENTAL SERVICES

REMEDIAL ACTION. The StanTech Group develops remedial action plans that are cost-effective and environmentally sound. Recent project experience includes the development and implementation of remediation plans for hydrocarbon impact, including acidic/lead-bearing petroleum wastes at petroleum refineries, tank farms, and disposal sites. Remedial actions included the treatment of acid-contaminated waters by lime neutralization, cement stabilization of pond sludges, and monofill construction for on-site sludge disposal. Remedial actions include excavation, treatment (in situ and ex situ), and disposal, and recovery, treatment (in situ and ex situ), and disposal/reuse of hydrocarbon-contaminated groundwater and free-phase hydrocarbons.

HEALTH AND SAFETY PLANNING AND MANAGEMENT. StanTech has personnel experienced in the development of health and safety plans for sites involving hazardous materials. Work is performed by professionals and technicians who have completed the 40-hour OSHA Health and Safety Training Course for Hazardous Waste Operations (29 CFR 1910.120).

UNDERGROUND STORAGE TANKS. StanTech is experienced in providing consulting for the Oklahoma State Underground Storage Tank Indemnity Fund. StanTech is a leader in this field and provided the plan for the first case to be awarded reimbursement by the State of Oklahoma. StanTech maintains close contact with the Oklahoma Corporation Commission.

ENVIRONMENTAL ASSESSMENTS. StanTech employs a phased approach to environmental assessments. Phase I Environmental Assessments are performed, per ASTM E-1527 to determine the current condition and to identify any existing or potential environmental concerns. A Phase II Investigation may follow to assess environmental concerns identified.

PHASE I ASSESSMENT. A Phase I Environmental Assessment includes a review of site history and ownership, analysis of historical aerial photography, a visit to the site to document the present surface conditions and operating practices, a review of regulatory agency records concerning the site and immediate vicinity, and preparation of a final report.

PHASE II ASSESSMENT. A Phase II Investigation may include sampling of surface soils, subsurface soils, surface water, and/or groundwater, depending on the specific environmental concerns. Some of the sampling and testing services which are available from StanTech are:

* Monitoring well design, installation, and development
* Single event, periodic, or long-term sampling
* In-house geotechnical analysis
* Soil borings and subsurface soil sampling
* Vadose zone and/or groundwater contaminant plume determination and migration analysis
* Recovery system design, installation, and monitoring
* Soil gas surveys
* Electrical resistively surveys

WATER AND GROUNDWATER RESOURCE MANAGEMENT.

StanTech has a staff of engineers, geologists, hydrologists, drillers, and environmental specialists with extensive experience in performing hydrogeologic assessments of contaminated and potentially-contaminated aquifer systems.

SUPPORTING SERVICES

The Environmental Services Division of StanTech is supported in depth by geotechnical engineering, drilling, analytical services, and construction materials testing personnel.

FIELD SUPPORT. For over forty years Standard Testing and Engineering Company has successfully supported construction projects throughout the United States.
