The Texas Well Owner Network, TWON, is hosting “Well Informed” water well screening events in Llano, Lampasas and Goldthwaite, Texas, Dec. 11-14 to allow residents to have their well water screened for possible contaminates.
John Smith, Texas A&M AgriLife Extension Service program specialist, College Station, said the Texas Well Owner Network program is for Texas residents who depend on household wells for their water needs.
“The TWON program was established to help well owners become familiar with Texas groundwater resources, septic system maintenance, well maintenance and construction, and water quality and treatment,” he said. “It allows them to learn more about how to improve and protect their community water resources.”
Water samples will be screened for contaminants, including total coliform bacteria, E. coli, nitrate-nitrogen and salinity.
Water sampling and meeting information
- Llano County: Dec. 11, water samples can be dropped off from 8-10 a.m. at the AgriLife Extension office for Llano County, 1447 E. State Highway 71, Unit E, in Llano. There will be a $15 per sample cost for the water screening.
On Dec. 12, the follow-up meeting to explain the results of the screenings will be from 6-7 p.m. at the St. James Lutheran Church, Schorlemmer Hall, 1401 Ford Street, Llano.
- Mills County: Dec. 12, water samples can be dropped off from 8:30-10 a.m. at the AgriLife Extension Office, 1011 4th Street (Courthouse), in Goldthwaite. There will be a $15 per sample cost for the water screening.
On Dec. 13, the follow-up meeting to explain the results of the screenings will be from 4-5 p.m. at the Mills County State Bank, 1103 Parker Street, Community Room, Goldthwaite.
- Lampasas County: Dec. 13, water samples can be dropped off from 8-10 a.m. at the AgriLife Extension office for Lampasas County, 409 S. Pecan Street, Lampasas. There will be a $15 per sample cost for the water screening.
On Dec. 14, the follow-up meeting to explain the results of the screenings will be from 1-2 p.m. at the Grace Fellowship Church, 2974 US-281, Lampasas.
Sampling instructions
Smith said area residents wanting to have their well water screened should pick up a sample bag, bottle and instructions from the Llano County AgriLife Extension office.
“It is very important that only sampling bags and bottles from the AgriLife Extension offices be used, and all instructions for proper sampling are followed to ensure accurate results,” he said.
Private water wells should be tested annually, he said. The samples will be screened for contaminants, including total coliform bacteria, E. coli, nitrate-nitrogen and salinity.
Smith said it is essential for those submitting samples to be at the follow-up meeting to receive results, learn corrective measures for identified problems and improve their understanding of private well management.
Well water contaminants, concerns
Smith said research shows the presence of E. coli bacteria in water indicates that waste from humans or warm-blooded animals may have contaminated the water. Water contaminated with E. coli is more likely to also have pathogens that can cause diarrhea, cramps, nausea or other symptoms.
The presence of nitrate-nitrogen in well water is also a concern, and water with nitrate-nitrogen at levels of 10 parts per million is considered unsafe for human consumption, he said.
“These nitrate levels above 10 parts per million can disrupt the ability of blood to carry oxygen throughout the body, resulting in a condition called methemoglobinemia,” Smith said. “Infants less than 6 months of age are most susceptible to this.”
Salinity, as measured by total dissolved solids, will also be determined for each sample, he said. Water with high levels may leave deposits and have a salty taste. Using water with high levels for irrigation may damage soil or plants.

The screenings are presented by AgriLife Extension and Texas Water Resources Institute, TWRI, in partnership with the AgriLife Extension office in Llano County.
Funding for TWON is through a Clean Water Act Section 319(h) nonpoint source grant provided by the Texas State Soil and Water Conservation Board and the U.S. Environmental Protection Agency. The project is managed by TWRI, part of Texas A&M AgriLife Research, AgriLife Extension and the Texas A&M College of Agriculture and Life Sciences.
