ENSAT was founded and grown as a site investigation and remediation company. This work continues to be the primary, core service area of ENSAT's consulting groups. We have designed, built, and operated numerous remedial systems in the mid-Atlantic region, and we have a strong reputation for technical competence and quality system installations amongst the client and regulatory communities in the region. We employ cost-effective and practical methods for site clean-up, stabilization, transportation, and disposal to assure the safety and welfare of your employees. ENSAT's team of geologists, engineers, and field personnel, are prompt, accurate, and specialize in working with government agencies to ensure regulatory compliance.

Our remediation and site investigation work has continuously expanded over the years, while many competitors have contracted in this market over the same period. In addition to our strong client-service orientation, ENSAT possesses a uniquely efficient design-build capability, which taps the greatest strengths of our combined consulting and construction service groups. ENSAT also has a strong reputation for completing investigations and remediation in very difficult situations, such as under buildings and beneath roadways. This challenging work requires special experience and innovative methods. Much of this work has been completed in the Washington, D.C. metropolitan area.

ENSAT has performed literally hundreds of site investigations involving releases of petroleum hydrocarbons. We have worked on numerous sites contaminated with chlorinated hydrocarbons, and have extensive experience with the specific technical concerns and fate and transport characteristics of these chemicals.

ENSATs experience in the area of groundwater supply in fractured rock settings is particularly valuable and applicable to many site investigations where contaminants have penetrated fractured bedrock. ENSAT has successfully completed numerous cases of petroleum hydrocarbons and chlorinated hydrocarbons in fractured bedrock, often where critical groundwater supply aquifers have been impacted. Many consultants lack extensive experience with the evaluation and characterization of contaminant occurrence and movement in fractured bedrock aquifers.
