Environmental Investigation Services
Whether it is a simple site assessment or a complex RCRA facility investigation, most environmental projects begin with determining the extent and type of contamination. This determination will guide cleanup decisions and may be determined by any or more of these exploratory actions:
- Review of regulatory records
- Review of aerial photographs
- Site visits
- Collection of samples and other site-specific data
- In-depth interviews with past and present property owners
A well-planned investigation saves money by reducing regulatory review, and efficiently collecting samples to maximize the information obtained by each one. SES provides water, soil, and air sampling services to help define problem areas and determine the type and severity of contamination.
Featured Projects
- SITE INVESTIGATION OF A SMALL ARMS RANGEBERM AREA – Fort Stewart, Georgia.
In preparation for major construction on the site of a former small arms firing range, SES delineated the extent of contamination by sampling soil, sediment, groundwater and surface water. Elevated levels of lead were found in multiple media. Findings from the investigation indicated the need for further delineation beyond the known extent of the berm encompassing a larger portion of the range fan and modifications to this project expanded it to over seven times its original contract value. Approximately 1,050 tons of contaminated soil were removed from the site. - RCRA FACILITY INVESTIGATION (RFI) AT SWMU 39 – Fort Stewart, Georgia.
Based on previous investigations to determine the extent of TCE contamination at SWMU 39 on Fort Stewart, SES performed an RFI at the site. This provided information for an ecological risk assessment. The investigation also included a revision of a human health risk assessment. SES recommended further action to remove free product by excavating an area around the well where the free product was present, replacing it with a larger diameter well, and continued monitoring of groundwater at the site. - RCRA FACILITY INVESTIGATION (RFI) AT FORMER SKEET RANGE – Fort Gordon, Georgia.
SES delineated soil contamination at the site of a former skeet range in Fort Gordon, Georgia, and prepared an RFI report. This included the delineation of PAH and metal contamination in soil and groundwater, obtained through samples collected from 39 soil borings installed up to 25 feet below ground surface, and from six groundwater monitoring wells. The results of this investigation were used for a baseline human health risk assessment from which SES recommended that soils be removed to five feet to remove all clay pigeons and PAH contaminated soils in the vicinity.
