Allen participates in the TCEQ lead and copper monitoring program. In-home lead and copper testing is conducted once by the City every three years. Our Annual Water Quality Report [PDF] and the Texas Drinking Water Watch website reflect the results of the most recent lead and copper testing.
To gather samples for this program, the City asks residents of 50 older homes built before 1986 to draw a “first morning” water sample for laboratory testing. Residents collect the first draw so the lead that is possibly in faucets or solder has had many hours to leach into the water at the tap. These 50 homes are all volunteers approved by the TCEQ for lead and copper program inclusion as “indicative” lead test sites for pre-1986 homes in the City.
After residents submit their samples to the City of Allen, we mail them to the designated state laboratory for testing. Test results are posted on the Texas Drinking Water Watch website and in our Annual Water Quality Report [PDF]. To use the DWW website, follow instructions provided above under the DBP discussion. For lead and copper results, see the “PBCU Summary” link.
Based on the water quality and human health issues caused by the drinking water of Flint, Michigan, the EPA will soon revise the lead and copper testing rules. We expect either tighter standards, more testing, or both to be required in the near future.
