Leaking Underground Storage Tank
Client: Ellingwood Construction Company
Location: Framingham, MA
Service: Pollution Assessment & Remediation
Underground gasoline and diesel fuel storage tanks, operated by a regional construction company, leaked and polluted soil and groundwater. The storage tanks were located in an aquifer protection district.
The Environmental Services Provided:
SAK served as the environmental consultant for response actions under the Massachusetts Contingency Plan up to Phase IV. The compromised tanks and 90 cubic yards of contaminated soil was removed. A monitored natural attenuation program was allowed as a feasible remedial action alternative under a 2007 amendment to the MCP (310 CMR 40.0924), because the site was located more than 1,000 feet from the public water supply wellhead.
SAK performed quarterly groundwater monitoring for 2 years on 7 monitoring wells. Water quality trends were statically evaluated using the Mann-Whitney U Test and determined that trends were significant.
Summary of Services:
- Site Remediation
- MCP Compliance
- Groundwater Remediation
- UST Removal
SAK developed a groundwater monitoring program with the end in mind, so that the data would be useful for risk characterization and statistical evaluation. A Class A-2 RAO was achieved to close out the project.
