Nebraska Administrative Code › Topic - HEALTH AND HUMAN SERVICES SYSTEM › Title 179 - PUBLIC WATER SYSTEMS › Chapter 12 - CONTROL OF LEAD AND COPPER › Section 179-12-009 - MONITORING REQUIREMENTS FOR LEAD AND COPPER IN TAP WATER

Current through June 17, 2024
009.01 Sample Site
				Location
12-009.01A Each water system must
				complete a materials evaluation of its distribution system in order to identify
				a pool of targeted sampling sites that meets the requirements of 179 NAC
				12-009, and which is sufficiently large to ensure that the water system can
				collect the number of lead and copper tap samples required in 179 NAC
				12-009.03. All sites from which first draw samples are collected must be
				selected from this pool of targeted sampling sites. Sampling sites may not
				include faucets that have point-of-use or point-of-entry treatment devices
				designed to remove inorganic contaminants.
12-009.01B The system must seek to collect
				the following information where possible in the course of its normal operations
				(e.g., checking service line materials when reading water meters or performing
				maintenance activities):
1. All plumbing
				codes, permits, and records in the files of the building department(s) which
				indicate the plumbing materials that are installed within publicly and
				privately owned structures connected to the distribution system;
2. All inspections and records of the
				distribution system that indicate the material composition of the service
				connections that connect a structure to the distribution system; and
3. All existing water quality information,
				which includes the results of all prior analyses of the system or individual
				structures connected to the system, indicating locations that may be
				particularly susceptible to high lead or copper concentrations.
12-009.01C The sampling sites
				selected for a community water system's sampling pool ("tier 1 sampling sites")
				must consist of single family structures that:
1. Contain copper pipes with lead solder
				installed after 1982 or contain lead pipes; and/or
2. Are served by a lead service line. When
				multiple-family residences comprise at least 20% of the structures served by a
				water system, the system may include these types of structures in its sampling
				pool.
12-009.01D Any
				community water system with insufficient tier 1 sampling sites must complete
				its sampling pool with "tier 2 sampling sites", consisting of buildings,
				including multiple-family residences that:
1.
				Contain copper pipes with lead solder installed after 1982 or contain lead
				pipes; and/or
2. Are served by a
				lead service line.
12-009.01E Any community water system with
				insufficient tier 1 and tier 2 sampling sites must complete its sampling pool
				with "tier 3 sampling sites", consisting of single family structures that
				contain copper pipes with lead solder installed before 1983. A community water
				system with insufficient tier 1, tier 2, and tier 3 sampling sites must
				complete its sampling pool with representative sites throughout the
				distribution system. For the purpose of 179 NAC 12-009.01E, a representative
				site is a site in which the plumbing materials used at that site would be
				commonly found at other sites served by the water system.
12-009.01F The sampling sites selected for a
				non-transient non-community water system ("tier 1 sampling sites") must consist
				of buildings that:
1. Contain copper pipes
				with lead solder installed after 1982 or contain lead pipes; and/or
2. Are served by a lead service
				line.
12-009.01G A
				non-transient non-community water system with insufficient tier 1 sites that
				meet the targeting criteria in 179 NAC 12-009.01F must complete its sampling
				pool with sampling sites that contain copper pipes with lead solder installed
				before 1983. If additional sites are needed to complete the sampling pool, the
				non-transient non-community water system must use representative sites
				throughout the distribution system. For the purpose of 179 NAC
				12-009.01G, a
				representative site is a site in which the plumbing materials used at that site
				would be commonly found at other sites served by the water system.
12-009.01H Any water system whose
				distribution system contains lead service lines must draw 50% of the samples it
				collects during each monitoring period from sites that contain lead pipes, or
				copper pipes with lead solder, and 50% of the samples from sites served by a
				lead service line. A water system that cannot identify a sufficient number of
				sampling sites served by a lead service line must collect first-draw samples
				from all of the sites identified as being served by such lines.
