Historical Exceedances

This facility has historically exceeded limits for the following parameters:

  • pH

    pH levels outside the normal range can harm aquatic life and affect water chemistry. Acidic water can leach toxic metals from sediments, while alkaline water can increase ammonia toxicity.

  • Total Suspended Solids (TSS)

    High levels of suspended solids can reduce water clarity, harm fish gills, smother aquatic habitat and eggs, and transport pollutants through water bodies.

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.
