      Watersheds and Their Contributions to Drinking Water Sources.

AB  - Wet flue gas desulfurization (FGD) wastewater discharges from coal-fired power 
      plants may increase bromide concentrations at downstream drinking water intakes, 
      leading to increased formation of toxic disinfection byproducts (DBPs). Despite 
      this, bromide was not regulated in FGD wastewater in the 2015 Effluent 
      Limitations Guidelines and Standards for the Steam Electric Power Generating 
      Point Source Category (ELGs). Case-by-case management was recommended instead, 
      depending on downstream drinking water effects. The present work seeks to 
      identify U.S. regions where power plant discharges could affect drinking water. 
      Bromide loads were evaluated for all coal-fired power plants operating wet FGD, 
      and flow paths were used to identify downstream surface water sources. A 
      population-concentration metric was used to evaluate the effect of wet FGD on 
      downstream drinking water and the vulnerability of drinking water to upstream 
      discharges. On a hydrologic region level, results indicate the Ohio, South 
      Atlantic Gulf, and Missouri Regions are the most likely to see effects of power 
      plant bromide discharges on populations served by surface water. Increased 
      refined coal use, which may be treated with bromide, contributes to uncertainty 
      in potential bromide effects on drinking water. Measurement of bromide 
      concentrations in wet FGD discharges would reduce this uncertainty, and control 
      of bromide discharges may be needed in some watersheds.
