Alark Hard Chrome, Riverside - Public Health Activities

In 2003, the California Department of Public Health--formerly California Department of Health Services (CDHS)--conducted an evaluation of the public health implications from contamination at the Alark Hard Chrome site.

The site

The Alark Hard Chrome site, located in Riverside, operated as a metal-plating facility between 1971 and 1985. A number of chemicals were handled at the facility, including metals, acids, cyanides, and volatile organic compounds. Activities at the site resulted in contamination of the soil and groundwater. In 1985, Alark Hard Chrome was closed down by the California Environmental Protection Agency's Department of Toxic Substances and Control for failure to comply with violation notifications. The site was then fenced, restricting access to the public.

In 2000, Alark Hard Chrome was listed on the U.S. Environmental Protection Agency (EPA)'s National Priorities List.

CDHS's involvement at the site

In 2003, CDHS released a public health assessment (PHA) for the Alark Hard Chrome site, under a cooperative agreement with the federal Agency for Toxic Substances and Disease Registry (ATSDR). The purpose of the PHA is to determine whether exposures to the site contamination might present a public health hazard to the surrounding community.

Summary of CDHS's findings

CDHS concludes that there is no past, current, or future health hazard from:

  • Exposure to contaminated soil.
  • Exposure to surface water and/or groundwater, provided remedial activities continue at the Alark Hard Chrome site.

As a result of these findings, CDHS recommended that EPA confirm the direction of groundwater flow and define the boundary of the contaminated groundwater plume. This is important so that remedial activities can be implemented to ensure protection of water quality in the area. If future investigations conducted at or near the site reveal additional sources of contamination that the community could come into contact with, CDHS and ATSDR will evaluate the data.
