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 Flowchart

    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.
