Feasibility Studies/Remedial Action Alternative Evaluations

Upon determining the need to conduct response actions to reduce, eliminate or minimize the presence of and/or human exposure to environmental contamination at a disposal site, CEA evaluates the range of possible remedial alternatives to determine which alternatives are suitable for use at the Site with respect to cost and technical implementability. The Remedial Action Alternative (RAA) evaluation focuses on the nature of the contamination at the Site, and the contaminant cleanup levels that must be met to achieve the project’s goals. CEA then prepares the design of the RAA that is to be implemented at the disposal site. Related tasks include:

  • Cost/Benefit Analyses
  • Evaluation and Selection of Remedial Alternatives
  • Design of Remedial Measures/Computer Aided Drafting and Design

The goal of the Remedial Action Alternative (RAA) evaluation is to select the RAA that is most likely to be effective in achieving the goals of the remedial action at the least cost to the client.

CEA PROJECTS

Remedial Alternative Evaluation, Conducted on behalf of a Residential Homeowner (2010) Residential Property, Sterling, MA

CEA evaluated groundwater and soil gas data and determined that in-situ treatment involving subsurface injection of Fenton’s reagent was the most suitable RAA to reduce petroleum hydrocarbon impacts in groundwater which if left untreated could lead to vapor intrusion.

Remedial Alternative Evaluation, Conducted on behalf of a Residential Homeowner (2012) Residential Property, Auburn, MA

CEA evaluated groundwater data and determined that in-situ treatment involving subsurface injections of hydrogen peroxide was the most suitable RAA to reduce petroleum hydrocarbon impacts in groundwater which if left untreated could threaten private drinking water well.

Remedial Alternative Evaluation, Conducted on behalf of an Independent Petroleum Retailer (2013) Gasoline Service Station Property, Carver, MA

CEA evaluated groundwater data and determined that use of an on-going Point of Entry Treatment (POET) system was the preferred RAA to restore use of the private potable water supply system at the site.

Remedial Alternative Evaluation, Conducted on behalf of a Major Petroleum Retailer (2013) Gasoline Service Station Property, Scituate, RI

CEA performed ongoing evaluation of the Site’s groundwater treatment system to determine the RAAs ability to prevent impacts on the Site’s potable water supply system and to achieve compliance with State of Rhode Island drinking water regulations.
