Cite as N.D. Admin. Code ยง 33.1-20-11-04
The leachate collection system and ground water monitoring network shall be analyzed for
background concentration of radionuclide parameters prior to receipt of any TENORM waste. Leachate
shall be analyzed for radionuclides at the same frequency as ground water samples are collected. If
radionuclides are detected in the leachate at a concentration greater than the concentrations listed
below, then the ground water monitoring network must begin analysis for radionuclide parameters.
Radon: 4,000 picocuries per liter (pCi/L).
Combined radium-226 and radium-228: 5 pCi/L.
Alpha particle activity (including radium-226, excluding radon and uranium): 15 pCi/L.
Uranium: 30 micrograms per liter (ug/L).
