Discovery Date:

July 2006

Contaminants of Concern (COCs):

  • Chromium
  • Nickel

Affected Media:

  • Soil
  • Groundwater

What Are My Health Risks?

For Soil | There is little to no health risk unless there is contact with skin or ingestion of contaminated soil.

For Groundwater | If you are connected to a Public Water System (PWS) there is little to no risk of impact from exceedances because the water is filtered through the PWS for residential and business use. | View Drinking Water Notices > 

If you have a private well in the vicinity of the exceedance, we encourage you to test the well water.
