Historical Exceedances

This facility has historically exceeded limits for the following parameters:

  • Iron, Total

    Excessive iron can harm aquatic ecosystems by forming precipitates that smother habitats. It can also affect fish gills and reduce visibility in water.

  • Zinc, Total

    Excessive zinc can be toxic to aquatic organisms, particularly fish. It can accumulate in sediments and aquatic life, potentially affecting the entire food chain.

  • Aluminum, Total

    Aluminum can be toxic to aquatic life, particularly in acidic conditions. It can accumulate in fish gills and affect their ability to take in oxygen.

These limits reflect Water Quality Standards promulgated to protect human health or the environment, or standards that the State or EPA developed to indicate the Facility may be failing to implement best practices to protect storm water.
