A study of radon-222 concentrations in North Carolina groundwater
- Univ. of North Carolina, Chapel Hill, NC (United States)
The groundwater of 400 North Carolina homes was sampled to ascertain the distribution and extent of 222Rn in North Carolina groundwater. Arithmetic mean (AM) and geometric mean (GM) concentrations of 1,816 pCi L-1 and 656 pCi L-1 were found for the state. These results indicate that two-thirds of 114°C. homes served by groundwater exceed the EPA proposed 300 pCi L-1 maximum contaminant level (MCL). Only 2% of NC homes exceeded 10,000 pCi L-1. The Eastern region had the lowest radon concentrations by far, with a GM of 2-)0 pCi L-1. The Central region and Western region had GM`s of 794 pCi L-1 and 1,032 pCi L-1 respectively. The groundwater data approached a log normal distribution. No consistent trends were noted in the relationship between indoor radon concentrations and groundwater radon concentrations. A correlation coefficient of 0.00921 revealed a very weak linear relationship.
