			 water (for the purpose of this section hereafter referred to as systems) must
			 sample at every entry point to the distribution system that is representative
			 of all sources being used (hereafter called a sampling point) under normal
			 operating conditions. The system must take each sample at the same sampling
			 point unless conditions make another sampling point more representative of each
			 source or the Department has designated a distribution system location, in
			 accordance with paragraph (2)(b)(ii)(C) of this section.
(ii) Applicability and sampling location for
			 new community water systems or sources. All new CWSs or CWSs that use a new
			 source of water must begin to conduct initial monitoring for the new source
			 within the first quarter after initiating use of the source. CWSs must conduct
			 more frequent monitoring when ordered by the Department in the event of

Current through Register Vol. 48, No. 6, June 28, 2024
(1) Suppliers of water for community public
			 water systems shall collect and analyze one (1) sample per plant at the entry
			 point of the distribution system for the determination of sodium concentration
			 levels; samples must be collected and analyzed annually for systems utilizing
			 surface water sources in whole or in part, and at least every three (3) years
			 for systems utilizing solely ground water sources. The minimum number of
			 samples required to be taken by the system shall be based on the number of
			 treatment plants used by the system, except that multiple wells drawing raw
			 water from a single aquifer may, with the Department's approval, be considered
			 one (1) treatment plant for determining the minimum number of samples. The
			 supplier of water may be required by the Department to collect and analyze
			 water samples for sodium more frequently in locations where the sodium content
			 is variable.
(2) The supplier of
			 water shall report to the Department the results of the analyses for sodium
			 within the first ten (10) days of the month following the month in which the
			 sample results were received or within the first ten (10) days following the
			 end of the required monitoring period as stipulated by the Department,
			 whichever of these is first. If more than annual sampling is required the
			 supplier shall report the average sodium concentration within ten (10) days of
			 the month following the month in which the analytical results of the last
			 sample used for the annual average was received.
(3) The supplier of water shall notify the
			 appropriate local public health officials of the sodium levels in the water by
			 written notice by direct mail within three (3) months after receiving the
			 results of analyses. Within ten (10) days after notifying the local public
			 health officials, the supplier of water shall forward a copy of such written
			 notice to the Department. The supplier of water is not required to notify local
			 public health officials where the Department provides such notices.
(4) Analysis for sodium shall be conducted
			 using EPA-approved methods listed in 40 CFR 141.

The Department shall perform such monitoring as is necessary to
				insure the quality and integrity of results of tests, measurements, or analyses
				reported by the supplier of water. Should such monitoring by the Department
				indicate a violation of the maximum contaminant levels, or the presence of any

				public's health, the Department at its discretion may notify the public or
				require the supplier of water to notify the public pursuant to R.61-58.6.E,
				or other method deemed appropriate by the Department and initiate the necessary
				action to eliminate the violation or contaminant.

When a public water system supplies water to one or more other
				public water systems, the Department may modify the monitoring requirements

South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-58.5 - Maximum Contaminant Levels in Drinking Water › Section 61-58.5.Y - Criteria and Procedures for Public Water Systems using Point-of-Entry Devices

Current through Register Vol. 48, No. 6, June 28, 2024
(1)
			 Public water systems may use point-of-entry devices to comply with maximum
			 contaminant levels only if they meet the requirements of this
			 section.
(2) It is the
			 responsibility of the public water system to operate and maintain the
			 point-of-entry treatment system.
(3) The public water system must develop and
			 obtain Department approval for a monitoring plan before point-of-entry devices
			 are installed for compliance. Under the plan approved by the Department,
			 point-of-entry devices must provide health protection equivalent to central
			 water treatment. "Equivalent" means that the water would meet all State primary
			 drinking water regulations and would be of acceptable quality similar to water
			 distributed by a well-operated central treatment plant. In addition to the
			 VOCs, monitoring must include physical measurements and observations such as
			 total flow treated and mechanical condition of the treatment
			 equipment.
(4) The public water
			 system must properly apply effective technology under a plan approved by the
			 Department and must maintain the microbiological safety of the water.
(a) The public water system must provide
			 adequate certification of performance, field testing, and, if not included in
			 the certification process, a rigorous engineering design review of the
			 point-of-entry devices.
(b) The
			 design and application of the point-of-entry devices must consider the tendency
			 for an increase in heterotrophic bacteria concentrations in water treated with
			 activated carbon. It may be necessary to use frequent backwashing,
			 post-contactor disinfection, and Heterotrophic Plate Count monitoring to ensure
			 that the microbiological safety of the water is not compromised.

(1) This
			 section establishes criteria and requirements for treatment techniques in lieu
			 of maximum contaminant levels for specified contaminants. This section applies
			 to all public water systems.
(2)
			 Treatment techniques for acrylamide and epichlorohydrin. Each public water
			 system must certify annually in writing to the Department (using third party or
			 manufacturer's certification) that when acrylamide and epichlorohydrin are used
			 in drinking water systems, the combination (or product) of dose and monomer
			 level does not exceed the levels specified as follows:
Acrylamide = 0.05% dosed at 1 ppm (or equivalent)
Epichlorohydrin = 0.01% dosed at 20 ppm (or equivalent)
Certifications can rely on manufacturers or third parties, as
				approved by the Department.

Current through Register Vol. 48, No. 6, June 28, 2024
With express written permission of the Department, concurred in
				by the Administrator, an alternative analytical technique may be employed. An
				alternative technique shall be acceptable only if it is substantially
				equivalent to the prescribed test in both precision and accuracy as it relates
				to the determination of compliance with any maximum contaminant level. The use
				of the alternative analytical technique shall not decrease the frequency of
				monitoring required by this regulation.

This regulation specifies the information public water supplies
				are required to report to the Department; the information they are required to
				retain; and the conditions and procedure for making public notification of a
				violation. This regulation shall apply to each public water system, unless the
				public water system meets all of the following conditions:
(1) Consists only of distribution and storage
			 facilities (and does not have any collection and treatment
			 facilities);
(2) Obtains all of its
			 water from, but is not owned or operated by, a public water system to which
