Once the site investigation phase of a contamination project has been completed, the risks to human health and the environment must be evaluated, corrective action taken (if necessary), and then site closure can be requested of the regulatory agency. At SNYDER GEOLOGIC, we have the capability and experience to take a project from investigation through site closure to bring a site back to productive use, or simply to eliminate conditions that pose a risk to site occupants.

Often times, a thorough evaluation of a site indicates that no remediation is necessary, and by implementing a few best management practices and/or institutional controls, a site can continue to operate as it has for years, but with the assurance the its workers or residents are not being exposed to hazardous levels of chemicals.

In cases where a risk of exposure is present, we evaluate the most expedient and cost effective solution to achieve the goal of a safe work or living environment. The solutions are not force fit into a situation, but rather we discuss potential remedial options with the owner to determine the best alternative for the situation. In some cases a temporary remedy is required until such time as a more permanent solution can be implemented, perhaps at a time when the site is being renovated or redeveloped.
