Former Manufacturing Facility Fitchburg, Massachusetts
Challenge
#6 oil was stored in an above-ground storage
tank located adjacent to a river, and across a
public road from a former manufacturing
facility. A small “day-tank” was used to store
heated #6 oil. The #6 oil was piped
underneath the public road to the plant for
heating and operations. #6 oil was detected
discharging to the river and through a granite
block bridge abutment, indicated a leak in the #6 oil storage and
transmission system.
Subsurface Environmental Solutions, LLC (SES) was retained to assist
Omni Environmental Group in understanding the extent and migration
pathway for the #6 oil. Existing laser-induced fluorescence (LIF) data was
augmented with traditional borings, and SES modeled the lateral and
vertical extent of migration and discharge locations to the river through both
soil and the bridge abutment.
SES Value Added
Interpreted and calibrated existing LIF data
Directed installation of continuous sample borings to confirm LIF data
Developed plan view map of of #6 oil extent
Created cross-section illustrating #6 oil
migration toward the bridge and river
Recommended vertical and lateral
excavation limits
