Areawide Soil Contamination Project
Toolbox Chapter 3
Because of the variability in the distribution of arsenic and lead from
area-wide soil contamination sources, individual property evaluations are
important to understand whether there is the potential for exposure to elevated
levels of arsenic and lead in soil at a particular property. Three types of
evaluation tools and guidance are provided here in order of use:
Individual Property Evaluation
This flowchart describes how individuals or organizations can use information
about a property’s location and land-use and development history to evaluate
whether elevated levels of arsenic and lead in soil are likely to be present.
Based on this information, individuals may choose to conduct soil sampling to
determine whether elevated levels of arsenic and lead are actually present,
and/or to implement protection measures to reduce any potential for exposure.
