(a) Information on the source of the water delivered must be included in the report.
(1) Each report must identify the source(s) of the water delivered by the community water system by providing information on the type of the water (such as surface water or groundwater) and any commonly used name and location of the body(ies) of water.
(2) If a source water assessment has been completed, the report must notify consumers of the availability of this information and the means to obtain it. In the reports, systems should highlight significant sources of contamination in the source water area if they have readily available information.
(3) If a system has received a source water assessment from the executive director, the report must include a brief summary of the system's susceptibility to potential sources of contamination using language provided by the executive director or written by a water system official and approved by the executive director.
(b) The following explanations must be included in the annual report.
(1) Each report must contain the following definitions.
(2) The following terms and their descriptions must be included when they appear in the report:
(3) A report for a community water system operating under a variance or an exemption of the Safe Drinking Water Act must include a description of the variance or the exemption granted under §290.102(b) of this title (relating to General Applicability).
(4) A report that contains data on a contaminant for which the United States Environmental Protection Agency (EPA) has set a treatment technique (TT) or an action level (AL) must include, depending on the contents of the report, the following definitions.
(c) Information on detected contaminants.
(1) This subsection specifies the requirements for information to be included in each report for detected contaminants subject to mandatory monitoring, excluding Cryptosporidium. Mandatory monitoring is required for:
(2) The data relating to these detected contaminants must be displayed in one table or in several adjacent tables. Any additional monitoring results that a community water system chooses to include in its reports must be displayed separately.
(3) The data must be derived from data collected to comply with EPA and the commission monitoring and analytical requirements during the previous calendar year, except when a system is allowed to monitor for regulated contaminants less often than once per year. In that case, the table(s) must include the date and results of the most recent sampling, and the report must include a brief statement indicating that the data presented in the report is from the most recent testing done in accordance with the regulations. The report does not need to include data that is older than five years.
(4) For detected regulated contaminants listed under §290.275 of this title, the table(s) must contain:
(5) For detected unregulated contaminants found under §290.275 of this title, for which monitoring is required (except Cryptosporidium ), the table(s) must contain the average and range of concentrations at which the contaminant was detected. The report must include the following explanation: "Unregulated contaminants are those for which EPA has not established drinking water standards. The purpose of unregulated contaminant monitoring is to assist EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulation is warranted."
(d) Information on Cryptosporidium, radon, and other contaminants.
(1) If the system has performed any monitoring for Cryptosporidium, the report must include a summary of the results of any detections and an explanation of the significance of the results.
(2) If the system has performed any monitoring for radon, which indicates that radon may be present in the finished water, the report must include the results of the monitoring and an explanation of the significance of the results.
(3) If the system has performed additional monitoring, which indicates the presence of other contaminants in the finished water, the executive director strongly encourages systems to report any results which may indicate a health concern. To determine if the results may indicate a health concern, the executive director recommends that systems find out if the EPA has proposed a standard in the NPDWR or issued a health advisory for any particular contaminant. This information may be obtained by calling the Safe Drinking Water Hotline at (800) 426-4791. The executive director considers detections that are above a proposed MCL or health advisory level to indicate possible health concerns. For such contaminants, the executive director recommends that the report include the results of the monitoring and an explanation of the significance of the results. The explanation should note the existence of a health advisory or a proposed regulation.
(4) Community water systems that exceed the secondary constituent level for fluoride as described in §290.118 of this title (relating to Secondary Constituent Levels) but are below the maximum contaminant level listed in §290.106 of this title (relating to Inorganic Contaminants) shall notify the public using the mandatory language as described in 40 CFR §141.208(c).
(e) Compliance with NPDWR. In addition to the requirements in subsection (c)(4)(H)(ii) of this section, the report must note any violation that occurred during the year covered by the report of a requirement listed in paragraphs (1) - (8) of this subsection.
(1) The report must include a clear and readily understandable explanation of each violation of monitoring and reporting of compliance data and explain any adverse health effects and steps the system has taken to correct the violation.
(2) The report must include a clear and readily understandable explanation of each violation of filtration and disinfection prescribed by Subchapter F of this chapter (relating to Drinking Water Standards Governing Drinking Water Quality and Reporting Requirements for Public Water Systems) and explain any adverse health effects and steps the system has taken to correct the violation. This applies both to systems that have failed to install adequate filtration, disinfection equipment, or processes, and to systems that have had a failure of such equipment or processes, each of which constitutes a violation. In either case, the report must include the following language as part of the explanation of potential adverse health effects: "Inadequately treated water may contain disease-causing Cont'd...
