When historical review or a site inspection suggests that soil or groundwater contamination exists, soil and water sampling may be necessary to evaluate the extent of the contamination. TPT's team of geologists and engineers has extensive experience in evaluating soil and groundwater contamination as part of a site characterization study. These investigations may be part of a Phase II environmental assessment, an underground storage tank (UST) investigation, a risk assessment or other type of project requiring actual site data to evaluate the presence, extent, degree and source of soil and/or groundwater contamination. Our services include:
Sampling Programs: TPT designs and implements sampling programs to evaluate soil, surface water and groundwater contamination. Sampling programs may be limited to collecting shallow soil samples using a hand auger or involve a full drilling program with installation of monitoring wells for groundwater sampling. TPT has a full range of soil sampling equipment including Geoprobe soil probe, a track-all-terrain drill and the longest hollow-stem auger vehicle in the central upper Midwest (CME 1050).
Modeling: TPT uses flow and transport models to simulate and assess surface and subsurface movement of water and contaminants, design and evaluate remedial action alternatives, and evaluate the effect of pollutant loads on surface water and groundwater quality. We can also use modeling data for risk assessment.
Investigation Reports: Based on the results of a sampling program, TPT can evaluate cost-effective and practical approaches to cleanups, if needed. Accurately defining the extent and magnitude of contamination is crucial to evaluating the need for further investigation and/or corrective action.
