contaminated soil. However, since exposure to elevated levels of pesticides can cause
adverse health effects, DTSC recommended that the property owner prepare a draft
RAW outlining how to cleanup contaminated soil. DTSC will oversee the cleanup
and ensure that it is performed in a manner that is protective of human health and
the environment.
