Removing the source of the contaminant is often the quickest way to resolve ongoing pollution problems and minimize environmental liability. EE&G has the capability of implementing the Remedial Action Plan whether it involves the removal of underground storage tanks or impacted soils. EE&G can take the project from assessment through to source removal and regulatory closure.
Just as assessments are tailor made for each site, so is the Remedial Action Plan (RAP). EE&G works closely with the client to minimize disturbance of site operations, or incorporate the remedial effort into site development plans. A successful site remediation results in regulatory approval. The receipt of a “No Further Action” letter from an agency brings peace of mind and allows real estate transactions to move forward. EE&G familiarizes itself with the appropriate regulatory requirements and works closely with the jurisdictional agency to insure the remediation action plan incorporates the necessary items for agency approval, incorporates the appropriate regulatory action levels, and operates in compliance with all permits and waste management requirements.
Dewatering is a crucial component for many surface and underground construction operations. EE&G provides the safest and most effective water drainage systems to its clients in an environmentally sound manner. It involves the removal or draining of ground or surface water from an environmental or construction site by pumping or evaporation.
Often site remediation will result in substantial reduction of contaminant levels but falls short of the clean up target levels. In cases where monitoring results consistently show little reduction in the contaminant level, EE&G may propose discontinued operation of the remediation system and recommend that the remaining contaminants be left in place to reduce naturally over time. Monitoring will continue until it can be shown that the levels continue to decline without additional remedial effort and the regulatory agency approves closure.
Typically required in the case of open release sites, EE&G helps clients assess the extent of groundwater contamination. The lateral and vertical extent of groundwater contamination and the rate at which it migrates toward sensitive receptors, such as surface water bodies and water supply wells, is evaluated through the installation and sampling of a network of monitoring wells. It is our priority to protect groundwater from pollutants and contaminants. We also guide our clients through the necessary procedures for site closure if needed.
Brownfields are abandoned industrial properties in which redevelopment may be complicated by the presence of hazardous substances, pollutants, or contaminants. Cleaning up and reinvesting in these properties protects the environment, reduces blight and takes development pressures off greenspaces and working lands. Brownfields can be anywhere: cities and suburbs, rural and tribal communities, and along coastlines. Approximately 450,000 brownfields exist in the U.S. today. EE&G works to reduce this number, which can increase local tax bases, facilitate job growth, utilize existing infrastructure and, most importantly, improve and protect the environment.
Site closure is a milestone achieved when the remaining contamination in the soil, surface water, groundwater, or air meets a risk threshold that does not pose a threat to human health or the environment. However, determining the end point of a corrective action at a leaking underground storage tank (LUST) site may involve reaching a targeted concentration of certain contaminants or reducing the risk of contamination to a specific threshold. Depending on the jurisdiction overseeing the remedial activity, completion of corrective action at a LUST site may be based on the remaining and foreseeable risk to human health and the environment.
