Soil contamination or soil pollution as part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alterations in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals, or improper disposal of waste.
petroleum spill analysis
A petroleum spill occurred from an aboveground storage tank at the subject property, leading to a potential Hazardous Site Response Act (HSRA) Notification Concentration and/or a Comprehensive Environmental Response, Recovery, Compensation, and Liability Act (CERCLA) Reportable Quantity. Immediate action was needed to ensure that no petroleum would reach the receiving waters, to ascertain whether or not the spill needed to be reported, and to ensure that no further spills took place.
The facility was visited by a representative of the Environmental Protection Division (EPD) who performed soil sampling to determine contamination concentration levels at the site that exceeded HSRA and CERCLA reportable limits. The client needed these analyses to be recorded in a sampling event document for future referencing.
Soil located on the subject property was thought to be contaminated with materials originating from roofing tar. The facility was thus required to ensure that all potentially harmful concentrations were below the Hazardous Site Response Act (HSRA) Notification Concentrations.
