Thomas Kwader tells us it never ceases to amaze him that site remediation systems are designed and installed frequently without knowing the extent of soil and groundwater contamination and the flow path(s) that groundwater migrates beneath a site.
When remediating a site, follow these steps: 1) locate the source of soil and groundwater contamination, 2) remove and/or isolate the source from additional contamination, 3) recover groundwater at "hottest" spot(s) in order to minimize additional groundwater contamination, and 4) recover groundwater near the leading edge of the plume in order to minimize migration from moving further down gradient.
