Case History: Soil Remediation & Groundwater Investigations 2017-08-01T10:12:15+00:00

Project Description

Jeff King, P.G., CEO of Pacific Environmental Remediation Corporation (PERC) and Founder of I2M Associates, LLC, provided project management via RI-FS preparation and approval by State for removal of soils below existing office buildings and associated shallow materials at a 5-acre State Superfund Site. The project consisted of removal of previous plant debris, soil washing (and soil replacement) of arsenic- and lead-contaminated soils, underlying sediments, and shallow groundwater, with the installation and quarterly sampling of numerous monitoring wells and 24/7 monitoring of the pressure distribution system within the shallow and intermediate aquifers to determine flow direction and rate of the migration of the contaminant plume, which are both subject to significant subsurface diurnal influences created by the Puget Sound tidal fluctuations nearby.

Soil characterization and groundwater investigations were conducted by and under the supervision of I2M’s Chief Hydrogeologist, Michael D. Campbell, P.G., P.H., former Regional Technical Manager (Central U.S.) of DuPont’s Environmental Remediation Services (DERS), based in Houston, Texas during the 1990s. See example of yearly continuous groundwater monitoring program of Shallow and Intermediate Aquifers (here), and one example of many flow-net analyses conducted at various snap-shots in time below.
