Investigation
STEP investigated and remediated a site in Florida which had been used for the disposal of radioactive laboratory waste. Debris removed from disposal trenches was scanned for radioactive materials.
STEP collected more than 600 soil samples from this site in Kentucky to determine the extent of pesticide contamination. After preparing the final investigation report, STEP recommended several disposal options and provided regulatory support to our clients.
STEP has performed dozens of investigative projects in our company’s history, and our field personnel have a great deal of experience in sampling techniques. We have characterized and completed studies of sites with contaminants such as
- asbestos;
- dioxins;
- metals;
- PCBs;
- pesticides;
- petroleum, oil, and lubricants (POL);
- radioactive waste;
- solvents; and
- unexploded ordnance.
Typical investigation projects involve a review of the site’s history, which can often provide clues to guide further investigative work. Individuals with site knowledge are interviewed. Depending upon the site conditions, aerial photos are sometimes consulted when contamination may be related to buildings or other structures which may be no longer standing at the site.
When sampling is required, we work closely with site representatives and regulators to determine the most efficient number and type of samples. This maximizes the amount of information, while minimizing associated costs. Once samples have been analyzed by the laboratory, data is returned to us electronically. Our engineers, geologist, and earth scientists review the information, and a report is prepared for the client, complete with our recommendations for further action. Other available services include data validation, and upload of electronic data to our client’s database.
