Abstract
The Addendum to the initial Draft 2018 State of South Carolina Integrated Report Part I (SCDHEC, 2020, IR Part I) identified a total of 169 Waters of Concern (WOC) due to total recoverable Lead. From the results presented herein, 156 of those WOC are currently meeting the lead standard with only 13 requiring ongoing monitoring, either due to 2 or more lead (Pb) standards exceedances or insufficient samples to make a determination. It is clear that concurrent measurements of metals, TSS, and hardness for the calculation of sample specific standards are crucial for the proper assessment of standards compliance and instream conditions. This information for receiving streams is also important for the development of reasonable and protective NPDES permit limits. Accordingly, all freshwater stream metals samples will now be accompanied by concurrent TSS and hardness analyses. Technical Report No. 1019-2020.
