Vapor Pin and Soil Gas Well Sampling

August 3, 2022

Due to the volatile nature of solvent and petroleum-related contaminants, the volatilization to indoor air pathway (VIAP) is often relevant during an environmental investigation at a manufacturing facility, dry cleaner, or gas station. The concern is that vapors, which off-gas from a contaminant body, will seep into a building and create unsafe conditions for the

Evaluating the GSI Pathway

June 16, 2022

When a contaminated site is located near a surface water body, there is a risk of contaminants in groundwater migrating into a lake or stream. If this is a potential route of conveyance, the Groundwater Surface Water Interface (GSI) pathway is taken into consideration during an exposure pathway evaluation. Since contaminant concentrations in groundwater do

When Should the Incremental Sampling Method be Used?

June 8, 2022

Common practice for soil sampling is to collect a discrete sample (soil from a known location and depth) from a few points and compare the analytical data to exposure criteria. In particular situations, discrete sampling is biased and not reproducible. For instance, if a soil sample is analyzed for arsenic and the aliquot of soil

These exposure pathways include: drinking water, direct contact, groundwater/surface water interface (GSI), and particulate or vapor inhalation. A conceptual site model (CSM), which is used to visualize the various exposure pathways that are applicable to a facility, is constructed through site characterization via
