When environmental contamination is discovered, CWE will work with you to investigate the severity, and quickly and safely implement the appropriate action. Our goal is to minimize harmful effects and restore the environment in compliance with regulatory requirements.

At a release site, our team works with you to determine the degree of hazard, gather site data, make recommendations and initiate the most efficient and effective way of bringing the spill/leak under control. We then conduct the sampling program to document the effectiveness of the cleanup action.

CWE works aggressively with Wisconsin regulators to close sites while maintaining an effective working relationship. Our environmental group quickly brings sites to closure, taking advantage of the most economical and innovative approaches, including:

•	natural attenuation
•	site specific soil standards and institutional controls
•	excavation and disposal of contaminated soils
•	installation of on-site treatment systems, such as soil vapor extraction, ground water extraction, air sparging, or free product removal systems

CWE promoted the use of natural attenuation to reduce long-term costs before WDNR first proposed flexible closure rules in 1996.

For years, our staff has worked closely with the PECFA program to ensure total compliance with the PECFA rules, and obtain full cost reimbursement.

Let us help you take advantage of the provisions in the COMM 47 rule to minimize cleanup costs and reduce delays in receiving PECFA reimbursements.

Whether your contamination concern is a water supply aquifer impacted by landfill leachate or a property transaction at a former gasoline station, CWE has the experience and capabilities to bring the project to a timely, cost-effective conclusion.
