ADDENDUM--GROUNDWATER AQUIFERS AT THE BRL SITE:
The subdivision of the water-bearing geologic formations presentedhere for the BRL site is a simplified version of the complex systemof aquifers identified at the site in the RI report (Versar, 1989). The following table illustrates the correspondence between thehydrogeologic units used in this Public Health Assessment and thoseidentified in the RI report.
| ODH Public Health Assessment Report | Remedial Investigation |
| Shallow zone aquifers (unconsolidated mine waste and bedrock exposed in vicinity of the Waste Pit) | "Shallow upper zone" (A) unconsolidated mine waste |
| "Deep upper zone" (A) Waynesburg Coal (AA) Wegee Limestone (B) Uniontown Sandstone "Deep upper zone" | |
| Deep zone aquifers (bedrock that occurs at depth [100+ ft] below the Waste Pit) | "Deep zone" (C) Redstone Limestone |
Calculations for Chemicals that do not cause cancer:
| Exposure Dose = | Medium Concentration x intake rate x exposure factor ------------------------------------------------------------------------------------ |
Medium Concentration= the concentration of the chemical in water or soil.
Intake Rate = The amount of water or soil a person would drink or ingest.
Exposure Factor = The amount of time in years that a person wouldbe exposed to the specific chemical. No exposure factor is used ifthe exposure occurs over a persons lifetime.
Body Weight = The amount a person weights. Generally 70 kilogramsis used for an adult and 10-15 kilograms for a child.
Calculation of risk for those chemicals that may cause cancer:
Lifetime Excess Cancer Risk =
Annual exposure dose x slope factor x exposure factor in years
Dose is in mg/kg/day
Slope factor = The U.S.EPA cancer slope factor, mg/kg/day
Exposure factor = The amount of time in years that a person wouldbe exposed to the specific chemical.
