  2. 2. On a date mutually agreed upon by the seller and the purchaser, and specifically included in a contract between the parties.
(3) Contents of the Report
1. (a) Each community water system must provide to its customers an annual report that contains the information specified in this paragraph and paragraph (4) of this rule.
2. (b) Information on the source of the water delivered:
  1. 1. Each report must identify the source(s) of the water delivered by the community water system by providing information on:
3. (i) The type of the water: e.g., surface water, ground water; and
4. (ii) The commonly used name (if any) and location of the body (or bodies) of water.
  1. 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 addition, systems are encouraged to highlight in the report significant sources of contamination in the source water area if they have readily available information. Where a system has received a source water assessment from the Department, the report must include a brief summary of the system’s susceptibility to potential sources of contamination, using language provided by the primacy agency or written by the operator.
5. (c) Definitions.
  1. 1. Each report must include the following definitions:
6. (i) Maximum Contaminant Level Goal or MCLG: The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.
7. (ii) Maximum Contaminant Level or MCL: The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
  1. 2. A report for a community water system operating under a variance or an exemption must include the following definition: Variances and Exemptions: Department or EPA permission not to meet an MCL or a treatment technique under certain conditions.
  2. 3. A report that contains data on contaminants that EPA regulates using any of the following terms must include the applicable definitions:
8. (i) Treatment Technique: A required process intended to reduce the level of a contaminant in drinking water.
9. (ii) Action Level: The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
10. (iii) Maximum residual disinfectant level goal or MRDLG: The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.
11. (iv) Maximun Residual Disinfectant Level or MRDL: The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for the control of microbial contaminants.
  1. 4. A report that contains information regarding a Level 1 or Level 2 Assessment required under Rule 0400-45-01-.41 must include the applicable definitions:
12. (i) Level 1 Assessment: A Level 1 assessment is a study of the water system to identify potential problems and determine (if possible) why total coliform bacteria have been found in our water system.
13. (ii) Level 2 Assessment: A Level 2 assessment is a very detailed study of the water system to identify potential problems and determine (if possible) why an E. coli MCL violation has occurred and/or why total coliform bacteria have been found in our water system on multiple occasions.
14. (d) Information on Detected Contaminants.
  1. 1. The reports shall specify the following report for contaminants subject to mandatory monitoring (except Cryptosporidium):
15. (i) Contaminants subject to a MCL, action level, maximum residual disinfectant level, or treatment technique (regulated contaminants).
16. (ii) Contaminants for which monitoring is required for unregulated contaminant monitoring by the Environmental Protection Agency and,
17. (iii) Disinfection by-products or microbial contaminants for which monitoring is required by the Information Collection Rule except as provided under part (e)1. of this paragraph and which are detected in the finished water.
  1. 2. The data relating to these contaminants must be displayed in one table or in several adjacent tables. Any additional monitoring results which a community water system chooses to include in its report must be displayed separately.
  2. 3. The data must be derived from data collected to comply with EPA and Department monitoring and analytical requirements during calendar year 1998 for the first report and subsequent calendar years thereafter except that:

21. (ii) The MCLG for that contaminant expressed in the same units as the MCL;
22. (iii) If there is no MCL for a detected contaminant, the table must indicate that there is a treatment technique, or specify the action level, applicable to that contaminant, and the report must include the definitions for treatment technique and/or action level, as appropriate, specified in part (c)3 of this paragraph;
23. (iv) For contaminants subject to an MCL, except turbidity total coliform, fecal coliform, and E. coli, the highest contaminant level used to determine compliance with an NPDWR and the range of detected levels, as follows:
  1. (I) If compliance with the MCL is determined annually or less frequently: The highest detected level at any sampling point and the range of detected levels expressed in the same units as the MCL;
  2. (II) When compliance with the MCL is determined by calculating a running annual average of all samples taken at a monitoring location: the highest average of any of the monitoring locations and the range of all monitoring locations expressed in the same units as the MCL. For the MCLs for TTHM and HAA5 in paragraph (6) of Rule 0400-45- 01-.06, systems must include the highest locational running annual average for TTHM and HAA5 and the range of individual sample results for all monitoring locations expressed in the same units as the MCL. If more than one location exceeds the TTHM or HAA5 MCL, the system must include the locational running annual averages for all locations that exceed the MCL.
  3. (III) When compliance with the MCL is determined on a system-wide basis by calculating a running annual average of all samples at all monitoring locations: the average and range of detection expressed in the same units as the MCL. The system is required to include individual sample results for the IDSE conducted under Rule 0400- 45-01-.37 when determining the range of TTHM and HAA5 results to be reported in the annual consumer confidence report for the calendar year that the IDSE samples were taken.

27. (ix) The likely source(s) of detected contaminants to the best of the operator's knowledge. Specific information regarding contaminants may be available in sanitary surveys and source water assessments, and should be used when available to the operator. If the operator lacks specific information on the likely source, the report must include one or more of the typical sources for that contaminant listed in Appendix A to this rule, which are most applicable to the system; and
28. (x) For E. coli analytical results under Rule 0400-45-01-.41: The total number of positive samples.
  1. 5. If a community water system distributes water to its customers from multiple hydraulically independent distribution systems that are fed by different raw water sources, the table shall contain a separate column for each service area and the report shall identify each separate distribution system, unless such systems produce and deliver separate reports to the customers of each service area tailored to include data for that service area.
  2. 6. The table(s) must clearly identify any data indicating violations of MCLs, MRDLs, or treatment techniques and the report must contain a clear and readily understandable explanation of the violation including: the length of the violation, the potential adverse health effects, and actions taken by the system to address the violation. To describe the potential health effects, the system must use the relevant language of Appendix A to this rule.
  3. 7. For detected unregulated contaminants for which monitoring is required (except Cryptosporidium), the table(s) must contain the average and range at which the contaminant was detected. The report may include a brief explanation of the reasons for monitoring for unregulated contaminants.
29. (e) Information on Cryptosporidium, radon, and other contaminants:
  1. 1. If the system has performed any monitoring for Cryptosporidium, including monitoring performed to satisfy the requirements of the information collection rule, which indicates that Cryptosporidium may be present in the source water or the finished water, the report must include:
30. (i) A summary of the results of the monitoring; and
31. (ii) An explanation of the significance of the results.
  1. 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:
32. (i) The results of the monitoring; and
33. (ii) An explanation of the significance of the results.
  1. 3. If the system has performed additional monitoring which indicates the presence of other contaminants in the finished water, systems are strongly encouraged to report any results which may indicate a health concern. To determine if results may indicate a health concern, it is recommended that systems find out if EPA has proposed a national primary drinking water regulation (NPDWR) or issued a health advisory for that contaminant by calling the Safe Drinking Water Hotline (800-426-4791). Detections above a proposed MCL or health advisory level indicate possible health concerns. For such contaminants, it is recommended that the report include:
34. (i) The results of the monitoring; and
35. (ii) An explanation of the significance of the results noting the existence of a health advisory or a proposed regulation.
36. (f) Compliance with NPDWR. In addition to the requirements of part (d)7. of this paragraph, the report must note any violation that occurred during the year covered by the report of a requirement listed in parts 1 through 7 of this subparagraph, and include a clear and readily understandable explanation of the violation, any potential adverse health effects, and the steps the system has taken to correct the violation.
  1. 1. A monitoring and reporting requirement.
  2. 2. Filtration and disinfection prescribed by Rules 0400-45-01-.17 and 0400-45-01- .31. For systems which have failed to install adequate filtration or disinfection equipment or processes, or have had a failure of such equipment or processes which constitutes a violation, the report must include the following language as part of the explanation of potential adverse health effects: Inadequately treated water may contain disease-causing organisms. These organisms include bacteria, viruses, and parasites which can cause symptoms such as nausea, cramps, diarrhea, and associated headaches;
  3. 3. Lead and copper control requirements prescribed by Rule 0400-45-01-.33. For systems which fail to take one or more actions prescribed by subparagraph (1)(d), paragraph (2), (3), (4) or (5) of Rule 0400-45-01-.33, the report must include the applicable language of Appendix A to this rule for lead, copper or both;

38. (h) Additional information:
  1. 1. The report must contain a brief explanation regarding contaminants which may reasonably be expected to be found in drinking water including bottled water. This explanation may include the language of subparts (i) through (iii) of this part or systems may use their own comparable language. The report also must include the language of subpart (iv) of this part.
39. (i) The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity.
40. (ii) Contaminants that may be present in source water include:
  1. (I) Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.
  2. (II) Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.
  3. (III) Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses.
    1. (IV) Organic chemical contaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, and septic systems.
    2. (V) Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining activities.
41. (iii) In order to ensure that tap water is safe to drink, EPA and the Tennessee Department of Environment and Conservation prescribe regulations which limit the amount of certain contaminants in water provided by public water systems. FDA regulations establish limits for contaminants in bottled water which must provide the same protection for public health.
42. (iv) Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline (800-426-4791).
  1. 2. The report must include the telephone number of the owner, operator, or designee of the community water system as a source of additional information concerning the report.
  2. 3. In communities with a large proportion of non-English speaking residents, as determined by the Department, the report must contain information in the appropriate language(s) regarding the importance of the report or contain a telephone number or address where such residents may contact the system to obtain a translated copy of the report or assistance in the appropriate language.
  3. 4. The report must include information (e.g., time and place of regularly scheduled board meetings) about opportunities for public participation in decisions that may affect the quality of the water.
  4. 5. The systems may include such additional information as they deem necessary for public education consistent with, and not detracting from, the purpose of the report.
  5. 6. A public water system’s report must include a statement that the wellhead protection plan and source water assessment are available for public review and identify the contact person, location, and time available for review of the plan.
  6. 7. Systems required to comply with Rule 0400-45-01-.41.
43. (i) Any system required to comply with the Level 1 assessment requirement or a Level 2 assessment requirement that is not due to an E. coli MCL violation must include in the report the text found in items (I), (II), and (III) of this subpart as appropriate, filling in the blanks accordingly, and the text found in subitems (IV)I. and II. of this subpart if appropriate.
  1. (I) Coliforms are bacteria that are naturally present in the environment and are used as an indicator that other, potentially harmful, waterborne pathogens may be present or that a potential pathway exists through which contamination may enter the drinking water distribution system. We found coliforms indicating the need to look for potential problems in water treatment or distribution. When this occurs, we are required to conduct assessment(s) to identify problems and to correct any problems that were found during these assessments.
  2. (II) During the past year we were required to conduct [INSERT NUMBER OF LEVEL 1 ASSESSMENTS] Level 1 assessment(s). [INSERT NUMBER OF LEVEL 1 ASSESSMENTS] Level 1 assessment(s) were completed. In addition, we were required to take [INSERT NUMBER OF CORRECTIVE ACTIONS] corrective actions and we completed [INSERT NUMBER OF CORRECTIVE ACTIONS] of these actions.
  3. (III) During the past year [INSERT NUMBER OF LEVEL 2 ASSESSMENTS] Level 2 assessments were required to be completed for our water system. [INSERT NUMBER OF LEVEL 2 ASSESSMENTS] Level 2 assessments were completed. In addition, we were required to take [INSERT NUMBER OF CORRECTIVE ACTIONS] corrective actions and we completed [INSERT NUMBER OF CORRECTIVE ACTIONS] of these actions.
    1. (IV) Any system that has failed to complete all the required assessments or correct all identified sanitary defects is in violation of the treatment technique requirement and must also include one or both of the following statements, as appropriate:
      1. I. During the past year we failed to conduct all of the required assessment(s). II. During the past year we failed to correct all identified defects that were found during the assessment.
        (ii) Any system required to conduct a Level 2 assessment due to an E. coli MCL violation must include in the report the text found in items (I) and (II) of this subpart, filling in the blanks accordingly, and the text found in subitems (III)I. and II. of this subpart, if appropriate.
        (I) E. coli are bacteria whose presence indicates that the water may be contaminated with human or animal wastes. Human pathogens in these wastes can cause short-term effects, such as diarrhea, cramps, nausea, headaches, or other symptoms. They may pose a greater health risk for infants, young children, the elderly, and people with severely compromised immune systems. We found E. coli bacteria, indicating the need to look for potential problems in water treatment or distribution. When this occurs, we are required to conduct assessment(s) to identify problems and to correct any problems that were found during these assessments.
        (II) We were required to complete a Level 2 assessment because we found E.coli in our water system. In addition, we were required to take [INSERT NUMBER OF CORRECTIVE ACTIONS] corrective actions and we completed [INSERT NUMBER OF CORRECTIVE ACTIONS] of these actions.
        (III) Any system that has failed to complete the required assessment or correct all identified sanitary defects is in violation of the treatment technique requirement and must also include one or both of the following statements, as appropriate:
        I. We failed to conduct the required assessment. II. We failed to correct all sanitary defects that were identified during the assessment that we conducted.
        (iii) If a system detects E. coli and has violated the E. coli MCL, in addition to completing the table as required in part (d)4. of this paragraph, the system must include one or more of the following statements to describe any noncompliance, as applicable:
        (I) We had an E. coli-positive repeat sample following a total coliform- positive routine sample.
        (II) We had a total coliform-positive repeat sample following an E. coli- positive routine sample.
        (III) We failed to take all required repeat samples following an E. coli- positive routine sample.
        (IV) We failed to test for E. coli when any repeat sample tests positive for total coliform.
        (iv) If a system detects E. coli and has not violated the E. coli MCL, in addition to completing the table as required in part (d)4. of this paragraph, the system may include a statement that explains that although they have detected E. coli, they are not in violation of the E. coli MCL.
        (4) Required additional health information.
        (a) All reports must prominently display the following language: “Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791).”
        (b) A system that detects arsenic above 0.005 mg/L and up to and including 0.01 mg/l:
        1. Must include in its report a short informational statement about arsenic, using language such as: “While your drinking water meets EPA's standards for arsenic, it does contain low levels of arsenic. EPA's standard balances the current understanding of arsenic's possible health effects against the costs of removing arsenic from drinking water. EPA continues to research the health effects of low levels of arsenic, which is a mineral known to cause cancer in humans at high concentrations and is linked to other health effects such as skin damage and circulatory problems.
        2. May write its own educational statement, but only in consultation with the Department.
        (c) A system which detects nitrate at levels above 5 mg/l, but below the MCL:
        1. Must include a short informational statement about the impacts of nitrate on children using language such as: Nitrate in drinking water at levels above 10 ppm is a health risk for infants of less than six months of age. High nitrate levels in drinking water can cause blue baby syndrome. Nitrate levels may rise quickly for short periods of time because of rainfall or agricultural activity. If you are caring for an infant you should ask advice from your health care provider.
        2. May write its own educational statement, but must obtain approval from the Department for it.
        (d) Every report must include the following lead-specific information:
        1. A short informational statement about lead in drinking water and its effects on children. The statement must include the following information: If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. [Name of Utility] is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using the water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead.
        2. A system may write its own educational statement, but only in consultation with the Department.
        (e) Community water systems that detect TTHM above 0.08 mg/L, but below the MCL as an annual average, must include the health effects language for TTHMs prescribed in Appendix A to this rule.
        (f) Beginning in the report due by July 1, 2002, and ending January 22, 2006, a community water system that detects arsenic above 0.01 mg/L and up to and including 0.05 mg/L must include the arsenic health effects language prescribed by Appendix A to this rule.
        (g) Any ground water system that receives notice from the Department of a significant deficiency or notice from the laboratory of a fecal indicator-positive ground water source sample that is not invalidated by the Department under subparagraph (3)(h) of Rule 0400-45-01-.40 must inform its customers of any significant deficiency that is uncorrected at the time of the next report or of any fecal indicator-positive ground water source sample in the next report. The system must continue to inform the public annually until the Department determines that a particular significant deficiency is corrected or the fecal contamination in the ground water is addressed under paragraph
        (4) of Rule 0400-45-01-.40. Each report must include the following elements:
        1. The nature of the particular significant deficiency or the source of the fecal contamination (if known) and the date the significant deficiency was identified by the Department or the dates of the fecal indicator-positive ground water source samples;
        2. If the fecal contamination in the ground water source has been addressed under Rule paragraph (4) of Rule 0400-45-01-.40 and the date of such action;
        3. For each significant deficiency or fecal contamination in the ground water source that has not been addressed under paragraph (4) of Rule 0400-45-01-.40, the Department-approved plan and schedule for correction, including interim measures, progress to date, and any interim measures completed;
        4. If the system receives notice of a fecal indicator-positive ground water source sample that is not invalidated by the Department under subparagraph (3)(h) of Rule 0400-45-01-.40, the potential health effects using the health effects language of Appendix A of this rule.
        (h) If directed by the Department, a system with significant deficiencies that have been corrected before the next report is issued must inform its customers of the significant deficiency, how the deficiency was corrected, and the date of correction under subparagraph (g) of this paragraph.
        (5) Report delivery and recordkeeping.
        (a) Except as provided in subparagraph (g) of this paragraph, each community water system shall mail or otherwise directly deliver one copy of the report to each customer.
        (b) The system shall make a good faith effort to reach consumers who do not get water bills, using means recommended by the Department. EPA expects that an adequate good faith effort will be tailored to the consumers who are served by the system but are not bill-paying customers, such as renters or workers. A good faith effort to reach consumers would include a mix of methods appropriate to the particular system such as: posting the reports on the Internet; mailing to postal patrons in metropolitan areas; advertising the availability of the report in the news media; publication in a local newspaper; posting in public places such as cafeterias or lunch rooms of public buildings; delivery of multiple copies for distribution by single-biller customers such as apartment buildings or large private employers; delivery to community organizations.
        (c) No later than the date the system is required to distribute the report to its customers, each community water system must mail a copy of the report to the Department, followed within 3 months by a certification that the report has been distributed to customers, and that the information is correct and consistent with the compliance monitoring data previously submitted to the Department.
        (d) No later than the date the system is required to distribute the report to its customers, each community water system must deliver the report to any other agency or clearinghouse identified by the Department.
        (e) Each community water system must make its reports available to the public upon request.
        (f) Each community water system serving 100,000 or more persons must make its current year’s report available for reading and downloading on the Internet.
        (g) The Governor of a State or his designee can waive the requirement of subparagraph
        (a) of this paragraph for community water systems serving fewer than 10,000 persons.
        1. Such systems must:
        (i) Publish the reports in one or more local newspapers serving the area in which the system is located;
        (ii) Inform the customers that the reports will not be mailed, either in the newspapers in which the reports are published or by other means approved by the Department; and
