SURFACE WATER RESULTS

NOTE: The data below represents surface water samples that were collected on March 12, 2014 by EPA START (Team 1) sampling teams. Water
sample measurements are in milligrams per liter (mg/L) and/or micrograms per liter (|a,g/L) for these samples. The data is being compared to EPA
ecological risk screening levels (ERSLs) to protect aquatic life in the surface water of the Dan River. Specific qualifiers and footnotes are listed below
the summary table. These samples were collected at various locations along the river (refer to map for generalized locations). The detected
concentrations in surface water are all below the EPA ERSLs with the exception of aluminum, copper, iron, and lead. EPA typically screens the surface
water concentrations using total metals samples, because this is a conservative practice for screening. Because none of these compounds were detected
above screening levels in any of the samples of the dissolved fraction of surface water (i.e., samples that were filtered to remove particulates), there is
no threat of toxicity to aquatic organisms. When chemical concentrations exceed the screening values it doesn't mean there will be adverse health or
ecological effects, but recommends further investigation may be needed.
