New River PCB TMDL

Since 2010, DEQ has generated several rounds of ambient water column and sediment PCB data in support of total maximum daily loads (TMDLs) for PCB polychlorinated biphenyls (PCBs) TMDL development for the New River watershed. Data collection, analyses and processing are currently underway. DEQ intends to conduct a series of public meetings and information sessions once the full dataset is processed. PCB data produced by this study will be used for TMDL development. The PCB ambient water and sediment data will provide information on potential sources and used to develop fate and transport model(s) from which load allocations can be applied relative to the different sources. Direct comparisons between surface water PCB concentrations and the water quality criterion for the protection of human health through fish consumption will also be made. Lastly, the ambient water data can be used in the derivation of a PCB endpoint(s) in water bodies where there is sufficient data and it is deemed the water quality criterion is not protective of the consumption use. For additional information please contact Mark Richards or Lucy Baker.
