The information below is to assist PWSs in finding a laboratory to perform the lead and copper analysis under the TCEQ National Laboratory Accreditation Program (NELAP). It is also for NELAP accredited laboratories assisting PWSs with lead and copper analysis.
- Laboratories must deliver and accept only one liter unpreserved wide mouth laboratory-grade bottles. (30 TAC §290.117(h)(1))
- First-draw tap samples should be received at the laboratory within 14 days after collection date so laboratories can preserve the samples. (30 TAC §290.117(h)(2)(E))
- Laboratories cannot accept bottles for analysis without TCEQ Form 20683 - LCR Chain of Custody completely filled out and signed by the PWS representative. This form has the necessary information on it to determine first-draw samples and sampling sites or addresses.

Water Quality Parameter Sampling Instructions and Guidance
Water Quality Parameters under the LCR are used to determine the corrosivity of the water flowing through the distribution system. All PWSs with a population over 50,000, new PWSs of all populations, and any PWS who have exceeded the action levels are required to sample for water quality parameters (WQP).
WQPs consist of: pH, alkalinity, temperature, conductivity, calcium, chloride, iron, manganese, sodium, sulfate, total dissolved solids, hardness and an inhibitor such as orthophosphate, if added.

Action levels for lead and copper are based on a 90th percentile calculation. The action level for lead is 0.015 mg/L and 1.3 mg/L for copper. If a PWS exceeds either of the action levels, it is required to conduct entry point and distribution water quality parameter sampling, entry point lead and copper sampling, and tap water lead and copper sampling. The PWS uses the sample results to submit a source water treatment recommendation, an optimal corrosion control treatment designation, and a corrosion control study. Lead action level exceedances also require delivery and posting of Lead Public Education (LPE).

On December 16, 2021, EPA announced next steps to strengthen the regulatory framework on lead in drinking water. Following the agency’s review of the Lead and Copper Rule Revisions (LCRR) under Executive Order 13990, EPA has concluded that there are significant opportunities to improve the rule to support the overarching goal of proactively removing lead service lines and more equitably protecting public health.
In a Federal Register Notice, EPA announced that the LCRR will go into effect to support near-term development of actions to reduce lead in drinking water. At the same time, EPA will develop a new proposed rulemaking to strengthen key elements of the rule. The agency anticipates finalizing the forthcoming Lead and Copper Rule Improvements (LCRI) prior to October 16, 2024, the initial compliance date in the LCRR.
CWSs and NTNCs with service lines (public or private) connected to the public water distribution system must complete a comprehensive spreadsheet inventory using form TCEQ-20943. (Rev. Date - 1/25/2023)
TCEQ is offering a free statewide program to help eligible participants conduct voluntary sampling and analysis for lead in drinking water at their schools and child care facilities.
