South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-58.11 - Control of Lead and Copper › Section 61-58.11.I - Monitoring requirements for Water Quality Parameters

Current through Register Vol. 48, No. 6, June 28, 2024
All large water systems, and all small and medium-size systems
				that exceed the lead or copper action level, and all small and medium-size
				water systems with corrosion control treatment that exceed the lead trigger
				level must monitor water quality parameters in addition to lead and copper in
				accordance with this section.
(1)
			 General Requirements
(a) Sample Collection
			 Methods
(i) Tap samples shall be
			 representative of water quality throughout the distribution system taking into
			 account the number of persons served, the different sources of water, the
			 different treatment methods employed by the system, and seasonal variability.
			 Tap sampling under this section is not required to be conducted at taps
			 targeted for lead and copper sampling under R.61-58.11.H(1).
			 Sites selected for tap samples under this section must be included in the site
			 sample plan specified under R.61-58.11.H(1)(a).
			 The site sample plan must be updated prior to changes to the sampling
			 locations. [Note: Systems may find it convenient to conduct tap sampling for
			 water quality parameters at sites used for coliform sampling under
			 R.61-58.5.G if they also meet the
			 requirements of this section.]
(ii)
			 Samples collected at the entry point(s) to the distribution system must be from
			 locations representative of each source after treatment. If a system draws
			 water from more than one source and the sources are combined before
			 distribution, the system must sample at an entry point to the distribution
			 system during periods of normal operating conditions (i.e., when water is
			 representative of all sources being used).
South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-58.11 - Control of Lead and Copper › Section 61-58.11.J - Monitoring Requirements for Lead and Copper in Source Water

Current through Register Vol. 48, No. 6, June 28, 2024
(1) Sample
			 Location, Collection Methods, and Number of Samples
(a) A water system that fails to meet the
			 lead or copper action level on the basis of tap samples collected in accordance
			 with R.61-58.11.H above, shall collect
			 lead and copper source water samples in accordance with the requirements
			 regarding sample location, number of samples, and collection methods.
(i) Groundwater systems shall take a minimum
			 of one (1) sample at every entry point to the distribution system after any
			 application of treatment or in the distribution system at a point which is
			 representative of each source after treatment (hereafter called a sampling
			 point). The system shall take one (1) sample at the same sampling point unless
			 conditions make another sampling point more representative of each source or
			 treatment plant.
(ii) Surface water
			 systems shall take a minimum of one sample at every entry point to the
			 distribution system after any application of treatment or in the distribution
			 system at a point which is representative of each source after treatment
			 (hereafter called a sampling point). The system shall take each sample at the
			 same sampling point unless conditions make another sampling point more
			 representative of each source or treatment plant.
NOTE: For the purposes of this paragraph, surface water systems
				include systems with a combination of surface and ground sources.
(iii) if a system draws water from
			 more than one source and the sources are combined before distribution, the
			 system must sample at an entry point to the distribution system during periods
			 of normal operating conditions (i.e., when water is representative of all
			 sources being used).
(iv) The
			 Department may reduce the total number of samples which must be analyzed by
			 allowing the use of compositing. Compositing of samples must be done by
			 certified laboratory personnel. Composite samples from a maximum of five (5)
			 samples are allowed, provided that if the lead concentration in the composite
			 sample is greater than or equal to 0.001 mg/L or the copper concentration is
			 greater than or equal to 0.160 mg/L, then either:
(A) A follow-up sample shall be taken and
			 analyzed within fourteen (14) days at each sampling point included in the
			 composite; or
(B) If duplicates of
			 or sufficient quantities from the original samples from each sampling point
			 used in the composite are available, the system may use these instead of
			 resampling.
