Services

OES experienced field staff operates and maintains a wide variety of remediation systems at both private and government facilities. These include free product recovery systems, groundwater pump and treatment systems, large or small-scale air-sparge and multi-phase extraction systems, in-place bioremediation technologies, groundwater treatment facilities and interceptor collection trenches. We provide full-time operation and maintenance of multiple groundwater extraction and treatment systems; troubleshooting, and preventative maintenance of equipment; collecting daily, monthly, and quarterly samples; process and discharge sampling; monitoring well sampling and maintenance; coordinating off-site disposal of all process-derived wastes; custodial and site security activities; responding to alarms or outages 24/7 and submitting timely reports to clients. Our technicians are e-RAILSAFE, SafeLand and ISNetworld certified.

Our diverse environmental services range from site investigations to corrective action plans for a variety of public sector and municipal, state, and federal entities.  We operate and maintain active remediation systems at several Air Force Bases and complete required groundwater monitoring, with strict quality control and quality assurance as specified by the government entity.

Developing cost-effective solutions to clean up contaminated sites requires experience and ingenuity. OES technical staff explores all practical alternatives to place our client interests first. Our team has an established record of performance and innovative approaches to remediating chemically impacted soil and groundwater, including in-place surfactant-enhanced remediation, microbial degradation, pump-and-treat remediation, mechanical air sparge and soil vapor extraction systems, free product removal systems and excavation and disposal.  As a full-service excavation company, OES experience ranges from small scale “dig and haul” remediation to larger scale projects requiring onsite soil blending and land farming.  OES evaluates each cleanup according to site location, surface cover, lithology, contaminate load, clean up goals and cost. The remedial technique selected is based on a final analysis of cost versus a successful environmental outcome.

With our Mobile Dual phase extraction process, subsurface contaminants are treated and collected for disposal or re-injected to the subsurface, where permissible under state laws. Our liquid ring vac rig delivers 28” Hg and 3790 CFM of airflow for maximum removal of subsurface liquids and vapors. The OES Guzzler Vac rig provides vacuum loading as a wet or dry vac, with a submerged hose for heavy liquids and semi-solids and air conveying for powders and dusts.

Federal and state laws require that petroleum storage tank systems employ release detection. OES offers an inexpensive, convenient Statistical Inventory Reconciliation (SIR) method of online entry and reporting, along with Groundwater Monitoring and Vapor Monitoring release detection methods that meet the EPA required 30-day reporting timeline.

An environmental risk investigation of a specific site may be part of the due diligence of a property transfer, or it can be in response to a suspected problem. OES environmental staff will assist the lender, developer, buyer, or seller perform a Phase I or Phase II ESA to readily establish the appropriate scope of work required. All our ESAs comply with current ASTM standards, revised according to EPA’s All Appropriate Inquiries (AAI) Rule.
