Project Experience: Blakeslee Prestress


Client: Blakeslee Prestress, Inc.

Location: Branford, Connecticut

Project: Phase II Subsurface Investigation and Contaminated Soil Excavation

Description:

  Blakeslee Prestress Inc., retained DES to investigate the extent of soil and groundwater contamination and perform any clean up necessary to prevent further migration of any contamination, as encouraged by the CTDEP under the Voluntary Remediation Program. The 36-acre industrial property was an episodic Large Quantity Generator (LQG) of hazardous waste in 1999 and was listed on the leaking underground storage tank (LUST) database, in October 1990.

  DES immediately initiated action by developing a Remedial Investigation Plan and installing twelve soil borings, in which eight were completed with monitoring wells to identify any contamination in surficial soils and groundwater. The investigation concluded petroleum contamination existed in five areas on the property, required remediation.

  DES provided oversight for the excavation of approximately 1,500 yards of contaminated soil. Confirmation soil samples were collected from each location. The results of the analysis indicated all petroleum impacted soil was removed from the site. Post remedial groundwater monitoring is currently being conducted to show the effectiveness of the soil remediation project. It is anticipated that monitoring will cease approximately one year from the start of the project.
