The state Department of Environmental Conservation has completed an investigation of a former gas plant site in West Babylon.
The investigation was performed at the site of the former National Grid West Babylon Manufactured Gas Plant located at 55 Evergreen St. An analysis was done from samples taken from the soil, groundwater and soil vapor, DEC officials stated.
The investigation found visible evidence of contamination at 3 feet to 30 feet below ground and at an adjacent property at 7.5 feet to 44 feet.
The primary chemical compounds detected in the site’s soil include benzene, toluene, ethylbenzene and xylenes (BTEX), and polycyclic aromatic hydrocarbons (PAHs). These contaminants were also found in groundwater, per both shallow and deeper wells, both on-site and at an adjacent property. The soil vapor was found to have low concentrations of BTEX.
A human health assessment found the potential for contamination with regard to construction activities at the site. As for the groundwater, DEC officials stated that the “water supply for the West Babylon community is from public water supply wells that are screened in a deeper aquifer zone so current or future use of groundwater at the site for a source of drinking water is very unlikely.”
The DEC will next develop a cleanup plan, called a Proposed Remedial Action Plan. The plan will be available for public review and it will be discussed at a public meeting.
