Environmental Monitoring & Compliance
The Division has a variety of programs to monitor the environment near
the ORR for hazardous materials. Monitoring efforts look at ground-
water, surface water, residential wells, underground storage tanks, sed-
iment, milk, vegetation, fish, and wildlife. The programs evaluate a wide variety
of radioactive and hazardous substances, including heavy metals, boron, cyanide,
nitrogen, ammonia, phosphate, pesticides, and PCBs.
The Division's groundwater programs range from independent sampling and
dye-trace testing to a review of DOE efforts. The Division oversees the plugging
and abandonment of wells on the ORR, samples off-site drinking water, and
helps collect and evaluate data for DOE's Oak Ridge Environmental Information
The Division in 1999 continued to identify residential wells that may be cont-
aminated with pollutants from the ORR. In 1996, Division staff had gone house
to house in an area bounded on one side by Black Oak Ridge near ETTP and on
the other by the intersection of Interstate 40 and Highway 95. In particular, they
were looking for families who use well water for drinking, cooking, and bathing.
The Division has identified 69 residential wells in this
area. In fiscal 1999, it tested 13 of these, which were Test results indi

inorganics, and metals. These tests allowed the Division
to evaluate the general groundwater quality and to identify chemicals and
radionuclides that had been used at the ORR. Results were compared to maxi-
mum contaminant levels established by the Safe Drinking Water Act.
The quality of water from these wells appears to be good. Most homeowners
interviewed continue to indicate no problem with groundwater quality, and test
results indicate that the water in these wells is adequate for drinking and house-
