Drinking Water Lead and Copper Program

Community (CWS) and non-transient non-community (NTNC) public water systems (PWSs) are required to sample inside plumbing (kitchen sinks and restroom sinks) under the Lead and Copper Rule (LCR). This page is intended for public water systems, laboratories, and the general public. You'll find a link to Texas Drinking Water Watch, instructions, forms, and laboratory information associated with the Lead and Copper Rule.

Texas Drinking Water Watch

Use this searchable database of analytical results, schedules and violations to learn more about the quality of your drinking water and your public water system's compliance with state and federal regulations.

2016 Systems

All community and non-transient non-community water systems are subject to LCR monitoring requirements.This area proides a list of PWS's scheduled to sample during the 6M1, 6M2, and reduced 2016 monitoring periods including the number of tap sample sites (2016 PWS lists are not meant to replace sample information found in DWW).

How Many Samples Are Required and When

System Size

 (number of people served)

Number of sites for

 Intial/Routine monitoring

Number of sites for Reduced monitoring:

1YR, 3YR, or 9YR

More than 100,000 100 50
10,001 to 100,000 60 30
3,301 to 10,000 40 20
501 to 3,300 20 10
101 to 500 10 5
100 or fewer 5 5

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


Tap Water Lead and Copper Forms

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

  • Form 20467 pdf.gif: Sample Site Selection and Materials for sampling pool
  • Form 20697 pdf.gif: Changing addresses from previously approved sampling pool
  • Form 20683 pdf.gif: LCR Chain of Custody, accompanies sample bottles to the laboratory for analyzing.
  • Form 20680a pdf.gif: Lead Consumer Notice, CWS PWS to report and certify customer lead results after the PWS receives the analytical results back from the laboratory.
  • Form 20680b pdf.gif: Lead Consumer Notice, NTNC PWS to report and certify customer lead results after the PWS receives the analytical results back from the laboratory.

 

LCR Action Level Exceeders

Action levels (ALE) for lead/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, the PWS is required to sample for water quality parameters, source water lead and copper sampling, and tap water lead/copper sampling as part of a corrosion control study. Lead action level exceedances also requires Lead Public Education (LPE) to be delivered and posted.

Laboratory Information

The information provided 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 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.
  • TCEQ NELAP Accreditation Program pdf.gif: Laboratories accredited by the State of Texas under NELAP.
  • For information on acceptable sampling methods under the Lead and Copper Rule, please see Accepted Sampling Methods Exit the TCEQ
  • Electronic Sampling Requirements: Contact the for electronic sampling requirements.

Water Quality Parameter Sampling

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, and an inhibitor such as orthophosphate, if added.

TCEQ approved laboratories are not necessarily the same as the TCEQ NELAP accreditied laboratories and have different approval requirements. Contact the TCEQ Laboratory Approval Coordinator for information.
