Dissolved Hydrocarbon Plume Delineation - Ferndale, Washington

is directing the monitoring of a dissolved phase groundwater plume (BTEX) as part of a MTCA independent remedial action. The next phase of the ongoing project will involve additional soil and groundwater characterization and plume delineation. A workplan is currently being negotiated which will propose collecting soil and groundwater samples from 16 locations at the site using a direct-push sampling drill rig. If the groundwater data indicates significant biodegradation of hydrocarbons downgradient of the spill source, monitored natural attenuation may be proposed as the remedial action for the site.
