Site Details
A brief history
The site is currently being used as a retail gas station with an automotive repair shop. Soil impact was first observed onsite in 2001 during the removal and replacement of four dispensers and the associated piping. Groundwater impact was confirmed in 2002.
Proposed Remediation Plan
An injection event occurred in August 2025 where 10,750 pounds of magnesium sulfate were injected into the aquifer to support the degradation of volatile organic compounds. Groundwater has been sampled periodically since the injections were completed to assess the degradation of the residual petroleum hydrocarbon compounds. An additional injection event is planned to occur at the site within the next year. Groundwater will continue to be monitored periodically to assess the effectiveness of the injections.
