Tap Sampling Instructions and Guidance

The information below includes the Environmental Protection Agency (EPA) sampling guidance along with PWS instructions and homeowner instructions. The PWS recommendations and guidance are to assist you in your sampling events and include the removal and cleaning of aerators, pre-stagnation flushing, and bottle configuration.

• Initial or Routine 6M Monitoring Period Instructions
• Reduced PWS Monitoring Instructions
• Guidance on Classification Tiers
• Homeowner instructions - English
• Homeowner instructions - Spanish

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.

Tap Sampling Requirements

Table 1: Number of Tap Samples Required for Initial/Routine and Reduced Monitoring based on population served.

Initial Sampling: Systems must complete two (2) rounds of consecutive six month sampling. The monitoring periods for collection are:

6M1: Jan 1 - June 30, analytical results are due to TCEQ no later than July 10

6M2: July 1 - Dec 31, analytical results are due to TCEQ no later than Jan 10

Reduced Sampling: Systems that have completed their two rounds of initial sampling can be reduced to 1 year or 3 year sampling based on their 90th percentile lead and copper sampling during their initial sampling period. Reduced monitoring has a second requirement of a seasonal sampling period:

Reduced: Jun 1 - Sept 30, analytical results are due to TCEQ no later than Oct 10

Lead and Copper Tap Sampling Forms

PWSs are required to use these forms to help them with Lead and Copper Rule sampling. All sampling site addresses should be reviewed before sampling and updated if needed.

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.

The number of samples listed above are sampled quarterly - twice within a six-month monitoring period.

For TCEQ to utilize sample analysis data, each sample must be analyzed by a NELAP Accredited laboratory or a TCEQ approved laboratory utilizing approved/accepted sampling methods and adhering to the Public Water System Supervision (PWSS) Program Quality Assurance Project Plan (QAPP).

• Please note that Initial and routine WQP samples, including field measurements for pH and temperature, must be collected in the presence of an individual holding a valid water operator's license.

Texas Drinking Water Public Laboratories Maps

Texas Drinking Water Public Laboratories Maps: TCEQ has developed the following maps to help you locate NELAP accredited public laboratories across the state of Texas that offer lead and copper or water quality parameter testing. Use the maps below to find a laboratory near you and their contact information. Always call laboratories to confirm their address, sample drop off hours, and prices.

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.

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.
