Client project details
Town of Rumford, ME (Groundwater Contaminant Assessment, Remediation, and Modeling)
Four hundred gallons of home heating oil spilled into a sand and gravel aquifer only a few hundred yards from a public water supply well serving the Rumford Water District. EGGI used angle drilling to investigate the spill beneath the basement floor of the home. Once the majority of the contamination was removed, EGGI performed a pumping test and investigated the potential for contamination of the Water District’s Well by constructing and calibrating a groundwater flow model. The model clearly demonstrated that a nearby stream effectively diverted all groundwater from the entire subdivision where the spill had occurred away from the Well. A series of groundwater flow model runs showed that the Well was in no danger of future contamination under any climatic conditions or pumping stresses.
The Maine Department of Environmental Protection was very pleased at the definitive nature of EGGI’s findings. The Rumford Water District was able to confidently rehabilitate the public water supply Well in question and put it into full operation once again.
"Your professionalism and ability to present complex technical details are very impressive. Your staff shares your commitment to go beyond the normal and expected tasks. I look forward to the next time that the DEP selects EGGI to work on a High-Priority Oil Remediation Project.”
