Waste Site Cleanup & Reuse in New England
St. Albans Gas and Light
The St. Albans Gas & Light Company, later known as the Vermont Lighting Company, manufactured gas from 1870-1953 in a residential area on property it had purchased that included five buildings. In 1971, three 20-unit apartment buildings, collectively known as the Colony Square Apartments, and two single-family homes were built on the site. In 2005 and 2006, EPA cleaned soils contaminated by the former coal gasification plant located near the two residential properties.
Heavy rains in the spring of 2011 overwhelmed the sump pumps in two of the Colony Square apartment building basements. Groundwater containing coal tar entered the basements. The VT Dept of Environmental Conservation and the St Albans Fire Department initially responded to the tenants' complaints of odors in their apartments and water in the basements. In early May, 2012, EPA analyzed about 250 soil and air samples and identified soil contamination. Elevated concentrations of coal tar compounds were also detected in occupied apartments. EPA determined that water drawn by the sump pumps contained coal tar constituents that were being discharged onto the lawn outside the buildings, and were also affecting indoor air quality.
The clean-up work started July 11, 2012. The top two feet of soil were excavated, then backfilled with topsoil replaced for all the grass areas. The 22 tons of the excavated contaminated soil were sent to the landfill in Moretown, VT. In addition, a test pit was excavated to search for a tank containing contaminants that was rumored to have been buried there. Another 230 feet of soil on the eastern bank of Steven's Brook were excavated and sent to the Moretown landfill. The stream bank was covered with geo fabric and covered with stone rip rap. On Sept. 4 and 6, 2012, EPA and its contractor made minor changes to the air mitigation systems and addressed some landscaping issues. On October 25, 2012, EPA concluded its work at the site.
