Section 5-1.48 - Reporting and recordkeeping requirements

(a)Reporting requirements for tap water monitoring for lead and copper and for water quality parameter monitoring.

(1) Unless the State has specified a more frequent reporting requirement, a water system shall report the following information for all tap water samples specified in section 5-1.42 of this Subpart and for all water quality parameter samples specified in section 5-1.43 of this Subpart to the State within the first 10 days following the end of each applicable monitoring period; for monitoring periods with a duration of less than six months, the end of the monitoring period is the last date samples can be collected during that period as specified in sections 5-1.42 and 5-1.43 of this Subpart:

(i) results of all first draw lead and copper tap samples collected in accordance with section 5-1.42 of this Subpart, including site locations and the criteria used in selecting the site in accordance with section 5-1.42(a)(1) of this Subpart;

(ii) documentation for each tap water lead or copper sample for which the water system requests invalidation in accordance with section 5-1.42(e) of this Subpart;

(iii) the 90th percentile lead and copper concentrations measured from among all lead and copper tap water samples collected during each monitoring period and calculated in accordance with section 5-1.41(c) of this Subpart, unless the State calculates the system's 90th percentile under subdivision (h) of this section;

(iv) with the exception of initial tap sampling conducted pursuant to section 5-1.42(b)(1)-(3) of this Subpart, the system shall identify any site which was not sampled during previous monitoring periods, and include an explanation of changes in sampling sites if any;

(v) the results of all tap samples for applicable water quality parameters collected in accordance with section 5-1.43(b)-(d) of this Subpart; and

(vi) the results of all samples collected at the entry point(s) to the distribution system for applicable water quality parameters under section 5-1.43(b)-(d) of this Subpart.

(2) For a nontransient noncommunity water system, or a community water system meeting the criteria of section 5-1.47(b)(2)(g) of this Subpart that does not have enough taps that can provide first-draw samples, the system shall provide written documentation to the State identifying standing times and locations for enough first-draw samples to make up its sampling pool by the start of the first applicable monitoring period in accordance with section 5-1.42(a)(3) of this Subpart or, identify in writing, each site that did not meet the six-hour minimum standing time and the length of time for that particular substitute sample collected, and include this information with the lead and copper tap sample results that are required to be submitted pursuant to subparagraph (a)(1)(i) of this subdivision.

(3) At a time specified by the State, or if no specific time is designated by the State, then as early as possible prior to the addition of a new source or any long-term change in water treatment, a water system deemed to have optimized corrosion control, a water system subject to reduced monitoring pursuant, or a water system subject to a monitoring waiver pursuant, shall submit written documentation to the State describing the change or addition as required under section 5-1.22(a) of this Subpart. A water system shall obtain approval from the State before implementing the addition of a new source or long-term change in water treatment. Examples of long-term treatment changes include the addition of a new treatment process or modification of an existing treatment process. Examples of modifications include switching secondary disinfectants, switching coagulants (e.g., alum to ferric chloride), and switching corrosion inhibitor products (e.g., orthophosphate to blended phosphate). Long-term changes can include dose changes to existing chemicals if the system is planning long-term changes to its finished water pH or residual inhibitor concentration. Long-term treatment changes would not include chemical dose fluctuations associated with daily raw water quality changes.

(4) Any system serving 3,300 or fewer persons applying for a monitoring waiver pursuant to section 5-1.42(f) of this Subpart, shall provide the following information to the State in writing by the specified deadline:

(i) by the start of the first applicable monitoring period, any system serving 3,300 or fewer persons applying for a monitoring waiver shall provide the documentation required to demonstrate that it meets the requirements of section 5-1.42(f) of this Subpart;

(ii) no later than nine years after the monitoring previously conducted pursuant to section 5-1.42(b) or (c) of this Subpart, each system serving 3,300 or fewer persons desiring to maintain its monitoring waiver shall provide the information required by section 5-1.42(f)(1)-(3) of this Subpart;

(iii) no later than 60 days after it becomes aware that it is no longer free of lead-containing and/or copper containing material, as appropriate, each system serving 3,300 or fewer persons with a monitoring waiver shall provide written notification to the State, stating the circumstances resulting in the lead-containing and/or copper-containing materials being introduced into the system and what corrective action, if any, the system plans to remove these materials.

(5) Each ground water system that limits water quality parameter monitoring to a subset of entry points under section 5-1.43(b)(2)(iii) of this Subpart shall provide by the commencement of such monitoring, written correspondence to the State that identifies the selected entry points and includes information sufficient to demonstrate that the sites are representative of water quality and treatment conditions throughout the system.

(b)Source water monitoring reporting requirements.

(1) A water system shall report the sampling results for all source water samples collected in accordance with section 5-1.44 of this Subpart within the first 10 days following the end of each source water monitoring period.

(2) With the exception of the first round of source water sampling conducted, the system shall specify any site which was not sampled during previous monitoring periods, and include an explanation of why the sampling point has changed.

(c)Corrosion control treatment reporting requirements.

By the applicable dates under section 5-1.41(c) of this Subpart or a date specified by the State, systems shall report the following:
