Sampling Instructions and Guidance
The Texas Commission on Environmental Quality (TCEQ) is including 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) PWS Monitoring Instructions
- REDUCED PWS Monitoring Instructions
- Guidance on Classification Tiers
- PWS homeowner instructions - English
- PWS homeowner instructions - Spanish
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 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.
- Lead and copper samples MUST be analyzed by a laboratory that is accredited in the "Drinking Water" matrix using an EPA approved drinking water method in the following table.

How Many Samples Are Required and When
|
System Size (number of people served) |
Number of sites for Initial/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 20467A : Sample Site Selection and Materials for sampling pool (Community water systems)
- Form 20467B : Sample Site Selection and Materials for sampling pool (Non-transient Non-community water systems)
TCEQ encourages public water systems to make available to the public any information regarding the location of lead plumbing, fixtures, and/or pipes including lead service lines. Methods to make this material publicly available include posting maps or other locational information on your system’s website, and adding into your Consumer Confidence Reports, Lead Consumer Notices, and Lead Public Education documents as applicable. TCEQ also encourages that the information be made available to your customers upon request.
- Form 20683 : LCR Chain of Custody, accompanies sample bottles to the laboratory for analyzing.
- Form 20680a : 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 : 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 Exceedance
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, the PWS 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). Forms and guidance documents are shown below:
- Form 20681a : Lead Public Education document for CWS PWSs
- Form 20681b : Lead Public Education document for NTNC PWS - Businesses
- Form 20681c : Lead Public Education document for NTNC PWS - Schools
- Lead Public Education Implementation
: For Community PWSs - EPA Lead Public Education Guidance for NTNC PWSs
- EPA Lead Public Education Posters
- Form 20495
: Corrosion Control Study - Form 20755 : Source Water Treatment Recommendation
- Form 20799 : Corrosion Control Treatment Installation Completion Certification
- Optimal Corrosion Control Treatment Evaluation Technical Recommendations
Technical recommendations that both systems and primacy agencies can use to comply with Lead and Copper Rule (LCR) corrosion control treatment requirements and to evaluate and designate optimal corrosion control treatment (OCCT) more effectively. - Lead and Copper Corrosion Bench-Scale Testing Guidance Manual: Guidance from the Colorado Department of Public Health on using a desktop study to evaluate OCCT. Including situations that necessitate corrosion testing, typical corrosion testing approaches, and processes for conducting a bench-scale immersion test.
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, chloride, iron, manganese, sodium, sulfate, total dissolved solids, hardness and an inhibitor such as orthophosphate, if added.
