South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-58.10 - Filtration and Disinfection › Section 61-58.10.F - Analytical and Monitoring Requirements

Current through Register Vol. 48, No. 6, June 28, 2024
(1) Analytical requirements.
Only the analytical method(s) specified in this paragraph, or
				otherwise approved by EPA, may be used to demonstrate compliance with the
				requirements of R.61-58.10.C,
				R.61-58.10.D, and R.61-58.10.E. Measurements for pH, temperature, turbidity and
				residual disinfectant concentrations shall be conducted by a party approved by
				the Department. Measurements for total coliforms, fecal coliforms, and HPC
				shall be conducted by a laboratory certified by the Department or EPA to do
				such analysis. Until laboratory certification criteria are developed for the
				analysis of HPC and fecal coliforms, any laboratory certified for total
				coliform analysis by EPA is deemed certified for HPC and fecal coliform
				analysis. All procedures shall be performed in accordance with EPA-approved
				methods outlined in 40 CFR 141 (11-8-06 edition).
(a) Fecal coliform concentration--Method 908C
			 (Fecal Coliform MPN Procedures), Method 908D (Estimation of Bacterial Density),
			 or Method 909C (Fecal Coliform Membrane Filter Procedure), as set forth in
			 Standard Methods for the Examination of Water and Wastewater, 1985, 16th
			 edition.
(b) Total coliform
			 concentration--Method 908A (Standard Total Coliform Multiple-Tube (MPN) Tests),
			 Method 908B (Application of Tests to Routine Examinations), Method 908D
			 (Estimation of Bacterial Density), Method 909A (Standard Total Coliform
			 Membrane Filter Procedure), or Method 909B (Delayed-Incubation Total Coliform
			 Procedure), as set forth in Standard Methods for the Examination of Water and
			 Wastewater, 1985, 16th edition; Minimal Medium ONPG-MUG Test, as set forth in
			 the article "National Field Evaluation of a Defined Substrate Method for the
			 Simultaneous Enumeration of Total Coliforms and Escherichia coli from Drinking
			 Water: Comparison with the Standard Multiple Tube Fermentation Method" (Edberg
			 et al.), Applied and Environmental Microbiology, Volume 54, June 1988 (as
			 amended under Erratum, Volume 54, December 1988). (Note: The Minimal Medium
			 ONPG-MUG Test is sometimes referred to as the Autoanalysis Colilert System.)
			 Systems may use a five-tube test or a ten-tube test.
(c) Heterotrophic Plate Count--Method 907A
			 (Pour Plate Method), as set forth in Standard Methods for the Examination of
			 Water and Wastewater, 1985, 16th edition.
(d) Turbidity--Method 214A (Nephelometric
			 Method-Nephelometric Turbidity Units), as set forth in Standard Methods for the
			 Examination of Water and Wastewater, 1985, 16th edition.
(e) Residual disinfectant
			 concentration--Residual disinfectant concentrations for free chlorine and
			 combined chlorine (chloramines) shall be measured by Method 408C (Amperometric
			 Titration Method), Method 408D (DPD Ferrous Titrimetric Method), Method 408E
			 (DPD Colorimetric Method), or Method 408F (Leuco Crystal Violet Method), as set
			 forth in Standard Methods for the Examination of Water and Wastewater, 1985,
			 16th edition. Residual disinfectant concentrations for free chlorine and
			 combined chlorine may also be measured by using DPD colorimetric test kits if
			 approved by the Department. Residual disinfectant concentrations for ozone must
			 be measured by the Indigo Method as set forth in Bader, H., Hoigne, J.,
			 "Determination of Ozone in Water by the Indigo Method; A Submitted Standard
			 Method"; Ozone Science and Engineering, Vol. 4, Pergamon Press Ltd., 1982, or
			 automated methods which are calibrated in reference to the results obtained by
			 the Indigo Method on a regular basis, if approved by the Department.
Residual disinfectant concentrations for chlorine dioxide shall
				be measured by Method 410B (Amperometric Method) or Method 410C (DPD Method),
				as set forth in Standard Methods for the Examination of Water and Wastewater,
				1985, 16th edition.
(f)
			 Temperature--Method 212 (Temperature), as set forth in Standard Methods for the
			 Examination of Water and Wastewater, 1985, 16th edition.
(g) pH--Method 423 (pH Value), as set forth
			 in Standard Methods for the Examination of Water and Wastewater, 1985, 16th
			 edition.
