RMS Environmental performed soil excavation and groundwater extraction at a residential property located in Lake Hopatcong, New Jersey to remediate heating oil impacted soils and groundwater. RMS teamed with ENR to perform the work. The banks of Lake Hopatcong were located less than 100 feet from the heating oil impacts which made it necessary to determine if any contamination had migrated to the lake. RMS also conducted vapor intrusion sampling due to the proximity of the residential home to the heating oil impacts.
