EPA's Brownfields Program empowers states, tribes.
communities, and other stakeholders to work together to
prevent, assess, safely clean up, and sustainably reuse
brownfields. A brownfield site is real property, the
expansion, redevelopment, or reuse of which may be
complicated by the presence or potential presence of a
hazardous substance, pollutant, or contaminant. EPA
funds eligible applicants through assistance agreements to
provide training, research, and technical assistance to
facilitate brownfields revitalization.
Organization Description
The mission of the California Department of Toxic
Substances Control (DTSC) is to provide the highest level
of safety to residents and protect public health and the
environment from toxic substances. DTSC regulates
hazardous waste, cleans up existing contamination, and
looks for ways to reduce the hazardous waste produced in
California. Approximately 1,000 scientists, engineers, and
specialized support staff make sure that companies and
individuals transport, store, treat, dispose of, and clean up
hazardous waste appropriately. Through these measures,
DTSC contributes to greater safety for all Californians.
Project Description
Mine-scarred lands in California are a major threat to
human health and the environment, and a major challenge
for brownfields revitalization. The California Department
of Conservation has identified 47,000 abandoned mines
in California. These mines present a threat to human
health and the environment from arsenic, mercury, and
other heavy metals, as well as from acid mine drainage
and physical hazards. Through this project, the California
Department of Toxic Substances Control will focus on
the threat to human health from arsenic at these mine-

scarred lands. Arsenic is the key chemical of concern at
the majority of brownfield projects at former gold mine
sites in the California Mother Lode and Southern
California desert areas. Due to the high cancer potency of
arsenic, sites are often required to be cleaned up to
background conditions. The project's research will
advance the science of characterizing arsenic at mine-
scarred land sites and improve the ability to determine
appropriate cleanup levels at arsenic-contaminated sites.
