Removal of contaminated soils for disposal at a treatment facility. According to the New York State Department of Environmental Conservation (NYSDEC), every year there are approximately 16,000 reports of confirmed and suspected releases to the environment. Approximately ninety percent of those releases involve petroleum products. The remaining releases involve various hazardous substances, unknown materials, or other materials such as untreated sewage and cooking grease. In most cases, the United States Environmental Protection Agency (USEPA), State Agency and/or local agencies will oversee the spill cases from the initial spill report to closure. Accidental and intentional releases that have impacted soil and/or groundwater can pose a significant human, wildlife and environmental health threat and can often require significant time and finances to remedy.

The first step of a petroleum spill remediation project is to determine remedial action objectives and goals. Gathering background information such as the extent and nature of contaminant(s) and hydrogeological characteristics of the site are necessary to maximize the potential for successful remediation. If feasible, the majority of source contamination in accessible dry and saturated soils is excavated and disposed of off-site at a waste treatment or disposal facility. In many cases, resultant groundwater contamination may be too deep or impractical to excavate. In such cases, groundwater contamination is commonly treated on-site ex-situ by means of pump and treat-type systems, and/or in-situ (in place) by means of technologies such as air sparging, vapor extraction, drawdown pumping/capture zones, natural degradation, enhanced bioremediation and permeable reactive barrier systems.
Spill closure and remediation projects can be highly complex and require forward thinking and experience. Please contact us to discuss your particular needs.
