Sampling

(1)

Applicability

This subsection applies with respect to sampling by a public water system of lead or copper in drinking water, irrespective of whether such sampling— (A)is required by the lead and copper rule; or (B)is voluntary sampling initiated by customers of the public water system. (2)

Reporting

Public availability of reports

A public water system shall make publicly available any report that is required by this section or by the lead and copper rule. (4)

Privacy

A public water system shall give the owner of each residential and nonresidential facility at which sampling data is collected the option to be identified only by block number and street name. (5)

Sampling protocol; instructions

The Administrator shall— (A)develop a protocol for sampling for compliance with the lead and copper rule; (B)in such protocol— (i)prohibit the use of techniques that minimize the detection of lead or copper in drinking water; (ii)require sampling under this section to occur not less than once per year; (iii)include criteria for site selection that prioritize testing at high-risk buildings; (iv)require sampling at all drinking water taps in all schools served by the public water system; and (v)require the sampling methodology to be scientifically based; and (C)develop instructions for compliance with such protocol for dissemination to public water systems and customers thereof. (c)

Action level exceeded

(1)

Investigations

The Administrator (or the State exercising primary enforcement responsibility) shall require on-site investigations on where the source of lead is for all individual samples with a lead or copper concentration above the action level— (A)to be completed by the public water system or local health department within 10 business days of the sample result; and (B)to include additional samples at additional locations to identify the potential scope of elevated lead or copper levels. (2)

Notification

Whenever a public water system detects a lead or copper concentration level above the action level, the system shall— (A)within 2 calendar days of detecting such an exceedance that is specific to one or more facilities, notify the persons at such facilities; and (B)within 10 calendar days of completion of sampling for a monitoring period applicable under section 141.86 of title 40, Code of Federal Regulations (or any successor regulation), make a report on any exceedance detected pursuant to such sampling publicly available. (d)

Public education

The lead and copper rule shall require testing results— (1)to be in a standardized format; (2)to be posted on the website of the Administrator, the State exercising primary enforcement responsibility, and the public water system; and (3)to include— (A)the provisions of consumer confidence reports under section 1414(c)(4) relating to lead and copper; (B)reports under subsection (b)(2) on the results of sampling; (C)lead service line replacement materials and financial assistance forms; and (D)how a consumer can request a water test. (e)

Service line inventory

A public water system shall— (1)develop, maintain, and beginning not later than 3 years after the date of enactment of the National Opportunity for Lead Exposure Accountability and Deterrence Act of 2017 make publicly accessible an inventory of the material composition of the service lines at all residential and nonresidential facilities, including— (A)online maps showing the locations of lead service lines; and (B)where information is available, a history of services performed on such lines, including partial line replacement; (2)give the owners of such residential and nonresidential facilities the option to be identified only by block number and street name; and (3)in developing such inventory, take measures to minimize any disturbance to service lines that might release contaminants. (f)

Service line ownership

A public water system shall collect, maintain, and beginning not later than 3 years after the date of enactment of the National Opportunity for Lead Exposure Accountability and Deterrence Act of 2017 make publicly accessible all legal documents establishing the ownership of service lines at residential and nonresidential facilities. (g)

Service line replacement

(1)

In general

Whenever a public water system replaces a lead service line, the lead and copper rule shall— (A)require the system to replace the line from the transmission line to where the line enters the facility; and (B)prohibit partial replacement. (2)
