Yellow indicates exceedance of Permit Benchmark Value or a CMSWS Action Level.NC Water Quality
In Stream Standards are also shown as a reference.
*Monitoring data collected during this event is based on total recoverable metals.
The values for the Industrial Stormwater Permits Discharge Benchmarks and CMSWS Action Levels are
also based on total recoverable metals.The NC Water Quality Standard for in-stream is based on dissolved
metals with an assumed in-stream hardness value of 25 mg/L.
