				Calculation of CT values.
(a) CT is the
				product of the disinfectant contact time (T, in minutes) and disinfectant
				concentration (C, in milligrams per liter). Systems with treatment credit for
				chlorine dioxide or ozone under paragraph (2) or (3) of this section must
				calculate CT at least once each day, with both C and T measured during peak
				hourly flow using EPA approved analytical methods.
(b) Systems with several disinfection
				segments in sequence may calculate CT for each segment, where a disinfection
				segment is defined as a treatment unit process with a measurable disinfectant
				residual level and a liquid volume. Under this approach, systems must add the
Cryptosporidium
CT values in each segment to determine the
				total CT for the treatment plant.

Alabama Administrative Code › Title 335 - ALABAMA DEPARTMENT OF ENVIRONMENTAL MANAGEMENT › WATER DIVISION - WATER SUPPLY PROGRAM › Chapter 335-7-11 - CONTROL OF LEAD AND COPPER › Section 335-7-11-.07 - Monitoring Site Selection

Current through Register Vol. 42, No. 9, June 28, 2024
Only monitoring conducted utilizing acceptable sites can be
				  used to determine compliance with this chapter. Water systems shall complete a
				  materials evaluation of its distribution system to identify targeted sample
				  sites. Sufficient sample sites shall be selected to allow an availability of
				  acceptable sites and thus allow monitoring based on the number of samples
				  required in Table 11-1.
(a) Monitoring
				sites for Community systems--Community water systems must conduct all lead and
				copper monitoring utilizing tier one sites or document the lack of sufficient
				sites and conduct the remaining monitoring from tier two sites. Water systems
				with insufficient tier one and two sites may utilize tier three sites. A
				community water system with insufficient tier one, two or three sites shall
				monitor utilizing replacement sites throughout the distribution system. A
				replacement 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 but not
				conforming to tier one, two or three requirements.
1. Any water system whose distribution system
				contains lead service lines shall conduct at least 50% of the monitoring from
				these sites during each monitoring period. Monitoring shall be conducted from
				the lead service line. Should a sufficient number of sites be unavailable to
				provide 50% of the required monitoring, written documentation is necessary to
				demonstrate why the system was unable to locate a sufficient number of such
				sites.
2. Tier one sites--These
				sites include single family structures containing lead pipe or plumbing, are
				served by a lead service line, or contain copper pipes with lead solder and
				were constructed after 1982.
3.
				Tier two sites--These sites include buildings and multiple family residences
				containing lead pipe or plumbing, are served by a lead service line, or contain
				copper pipes with lead solder and were constructed after 1982.
4. Tier three sites--These sites include
				single family structures containing copper pipes with lead solder which were
				constructed prior to 1983.
Alabama Administrative Code › Title 335 - ALABAMA DEPARTMENT OF ENVIRONMENTAL MANAGEMENT › WATER DIVISION - WATER SUPPLY PROGRAM › Chapter 335-7-11 - CONTROL OF LEAD AND COPPER › Section 335-7-11-.08 - Lead/Copper Monitoring Collection Procedures

Current through Register Vol. 42, No. 9, June 28, 2024
Tap and service line monitoring shall be collected in
				  accordance with the following:
(a) Tap
				monitoring for lead and copper shall be first draw and one liter in volume. The
				water shall stand motionless in the plumbing system for at least six hours
				prior to collection. Collection shall be from the cold water kitchen tap or
				bathroom sink tap from tier 1 sites or from an interior tap typically used for
				obtaining water for consumption from tier 2 and tier 3 sites. Monitoring may be
				conducted by the resident after proper instructions and procedures have been
				provided by the water system. Follow up tap monitoring shall be conducted from
				the same sites. Should a site no longer be available, an alternate acceptable
				site may be selected which is in reasonable proximity of the original site.
				Taps used for monitoring may not include faucets that have point of use or
				treatment devices installed.
(b)
				Service line monitoring shall be one liter in volume and have remained in the
				lead service line for at least six hours prior to collection. Service line
				monitoring may be collected directly by tapping into the lead service line, or
				by flushing the volume of water between the tap and the lead service line until
				either the calculated amount of water between the tap and the service line has
				been discharged or for single family residences until there is a significant
				change in temperature which would indicate the water available was standing in
				the lead service line.
(c) Water
				systems with insufficient taps that can supply first draw samples may apply to
				the state in writing to substitute non -first-draw samples. These systems must
				collect as many of the samples as possible from first-draw taps and identify
				the monitoring times and locations that would likely result in the longest
				standing times for the remaining samples. Non-first-draw samples shall be one
				liter in volume and collected from an interior tap from which water is
				typically drawn for consumption.

A sample invalidated under this rule does not count toward
				  90th percentile levels or toward meeting minimum monitoring
				  requirements.
(a) A sample may be
				invalidated for one of the following reasons.
1. The laboratory establishes that improper
				sample analysis caused erroneous results.
2. The State determines that the sample was
				taken from a site that did not meet the site selection criteria of this
				rule.
3. The sample container was
				damaged in transit.
4 There is substantial reason to believe that the sample was
				  subject to tampering.

Any water system with an action level exceeding the
				  compliance limit for lead or copper shall complete the following requirements
				  in the manner and by the deadline established by these regulations:
(a) Water systems must install and maintain
				adequate corrosion control treatment equipment to ensure that the lead/copper
				compliance limit can be met. The Department may require that an in-depth study
				be completed to determine the optimum corrosion control process for the
				system.
(b) Systems installing
				corrosion control treatment requirements shall monitor the parameters at the
				frequency established by these regulations. All parameters established must be
				reported on the monthly operation data reports by the 10th of the following
				month. Exceedance of the established values which indicate optimum corrosion
				control is considered a treatment technique violation.
(c) The lead and copper level in the source
				water serving the areas exceeding the compliance limit must be monitored to
				determine compliance with the primary drinking water standards in Chapter
				335-7-2. The source must be taken out of service and provided with satisfactory
				treatment, approved by the Department, to reduce the lead or copper level to
				meet these drinking water standards.
(d) A system that fails to meet the
				lead/copper compliance limit after the installation of corrosion control shall
				develop a program to replace lead service lines. All lead service lines in the
				system shall be identified and at least 7% replaced on an annual basis. More
				rapid replacement may be required by the department.
(e) Systems which exceed the lead compliance
				limit shall deliver public educational materials according to the methods
				specified in the regulations. The language used in this public education notice
				must include specific language contained in the Appendix C.
