"Tc
5 IIg/L 25 pCi/L
100 IIg/L 100 pCi/L
1000 IIg/L 900 pCi/L
10,000 IIg/L 3790 pCiiL
100,000 IIg/L 10,000 pCi/L
The contour intervals for 99Tc reflect in part
detection limits (25 pCiIL) or regulatory
benchmarks (900 and 3790 pCi/L). After
contouring was completed, the maps were
digitized and a composite map created by
combining the three interval maps for TCE and
99Tc.
The remaining tables of data sets and
graphs in the report, Trichloroethene and
Technetium-99 Groundwater Contamination in
the Regional Gravel Aquifer for Calendar Year
1999 at the Paducah Gaseous Diffusion Plant,
Paducah, Kentucky, (BJCIPAD-169), are
available in the DOE Environmental
Information Center.
