(a) The following methods or with the alternative methods listed in Appendix A to Subpart C of 40 CFR 141, or their equivalent determined by the U.S. EPA in accordance with 40 CFR 141.27, shall be used to determine compliance with sections 9 through 10 of this rule, except in cases where alternative methods have been approved in accordance with section 32 of this rule: (1) One (1) of the following methods shall be used to test for gross alpha and beta1: (B) Page 1 of "Interim Radiochemical Methodology for Drinking Water*".(D) Page 1 of "Radiochemical Analytical Procedures for Analysis of Environmental Samples*".(2) One (1) of the following methods shall be used to test for gross alpha1: (3) One (1) of the following methods shall be used to test for radium 226:(C) Page 16 of "Interim Radiochemical Methodology for Drinking Water*".(D) Page 13 of "Interim Radiochemical Methodology for Drinking Water*".(G) Page 19 of "Radiochemical Analytical Procedures for Analysis of Environmental Samples*".(4) One (1) of the following methods shall be used to test for radium 228:(B) Page 24 of "Interim Radiochemical Methodology for Drinking Water*".(D) Page 19 of "Radiochemical Analytical Procedures for Analysis of Environmental Samples*".(5) One (1) of the following methods shall be used to test for uranium2: (D) Page 33 of "Radiochemical Analytical Procedures for Analysis of Environmental Samples*".(6) One (1) of the following methods shall be used to test for radioactive cesium:(C) Page 92 of "Radiochemical Analytical Procedures for Analysis of Environmental Samples*".(K) Page 4 of "Interim Radiochemical Methodology for Drinking Water*".(7) One (1) of the following methods shall be used to test for radioactive iodine:(C) Page 6 of "Interim Radiochemical Methodology for Drinking Water*".(D) Page 9 of "Interim Radiochemical Methodology for Drinking Water*".(E) Page 92 of "Radiochemical Analytical Procedures for Analysis of Environmental Samples*".(8) One (1) of the following methods shall be used to test for radioactive strontium 89 and 90: (B) Page 29 of "Interim Radiochemical Methodology for Drinking Water*".(D) Page 65 of "Radiochemical Analytical Procedures for Analysis of Environmental Samples*".(9) One (1) of the following methods shall be used to test for tritium:(B) Page 34 of "Interim Radiochemical Methodology for Drinking Water*".(D) Page 87 of "Radiochemical Analytical Procedures for Analysis of Environmental Samples*".(10) One (1) of the following methods shall be used to test for gamma emitters:(D) Page 92 of "Radiochemical Analytical Procedures for Analysis of Environmental Samples*".(K) Method Ga-01-R*. 1 Natural uranium and thorium-230 are approved as gross alpha calibration standards for gross alpha with coprecipitation and evaporation methods; americum-241 is approved with coprecipitation methods.2 If uranium (U) is determined by mass, a 0.67 pCi/µg of uranium conversion factor must be used. This conversion factor is based on the 1:1 activity ratio of U-235 and U-238 that is characteristic of naturally occurring uranium.(b) When the identification and measurement of radionuclides other than those listed in subsection (a) is required, the following references are to be used, except in cases where alternative methods have been approved in accordance with section 32 of this rule: (1) Procedures for Radiochemical Analysis of Nuclear Reactor Aqueous Solutions, H.L. Krieger and S. Gold, EPA-R 4-73-014, U.S. EPA, Cincinnati, Ohio, May 1973.(2) HASL Procedure Manual, edited by John H. Harley. HASL 300, ERDA Health and Safety Laboratory, New York, New York 1973.(c) For the purpose of monitoring radioactivity concentrations in drinking water, the required sensitivity of the radioanalysis is defined in terms of a detection limit. The detection limit shall be that concentration that can be counted with a precision of plus or minus one hundred percent (100%) at the ninety-five percent (95%) confidence level (one and ninety-six hundredths (1.96) [SIGMA] where [SIGMA] is the standard deviation of the net counting rate of the sample). Compliance requirements are as follows: (1) To determine compliance with section 9(1) of this rule, the detection limit shall not exceed one (1) picocuri per liter.(2) To determine compliance with section 9(2) of this rule, the detection limit shall not exceed three (3) picocuri per liter.(3) To determine compliance with section 9(3) of this rule, the detection limit shall not exceed one (1) microgram per liter.(4) To determine compliance with section 10 of this rule, the detection limits shall not exceed the concentrations listed in the following table: | |
| Detection limits for manmade beta particle and photon emitters: |
| Radionuclide | Detection limit |
| Tritium | 1,000 pCi/l |
| Strontium-89 | 10 pCi/l |
| Strontium-90 | 2 pCi/l |
| Iodine-131 | 1 pCi/l |
| Cesium-134 | 10 pCi/l |
| Gross beta | 4 pCi/l |
| Other radionuclides | 1/10 of the applicable limit |
(d) To determine compliance with the MCL listed in sections 9 through 10 of this rule, averages of data shall be used and shall be rounded to the same number of significant figures as the MCL for the contaminant in question. *The methods referenced in this section may be obtained as follows:
