Private water well screenings set for Feb. 9-10 in Briscoe, Hall counties
Residents are invited to test their well water and review results
The Texas Well Owner Network, TWON, will host a private water well screening for Briscoe County and Hall County residents on Feb. 9-10 in Silverton and Memphis.
Joel Pigg, Texas A&M AgriLife Extension Service program specialist and TWON coordinator, Texas A&M Department of Soil and Crop Sciences, Bryan-College Station, said the Texas Well Owner Network program is for 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,” Pigg said. “It allows them to learn more about how to improve and protect their community water resources.”
There is a $15 cost per sample. Water samples will be screened for contaminants, including total coliform bacteria, E. coli, nitrate-nitrogen and salinity.
Water sampling and meeting information
Water samples can be dropped off on Feb. 9 from 8:30-11 a.m. at the following locations:
- AgriLife Extension office in Briscoe County, 415 Main St., Silverton.
- AgriLife Extension office in Hall County, 101 S. Ninth St., Memphis.
The results and educational meeting for both counties will be held from 11 a.m. to noon on Feb. 10 at the Silverton Downtown Association Community Center, 507 Commerce St., Silverton.
Sampling instructions
Attendees are asked to follow these instructions to collect their well water sample:
- Empty the contents of a new bottle of water, 12-20 ounces, and fill it with a water sample from your private water well.
- Take the sample from the spigot/hose bib nearest the wellhead. If a water hose is present, remove it and take the water directly from the spigot/hose bib.
- If an inside faucet is used, remove the faucet aerator before making the collection. Rinse and dry the exterior of the faucet to prevent contamination of the water sample.
- If possible, wipe with a Clorox-type towelette or paper towel dampened with a light bleach solution to kill any bacteria present on the faucet. Allow the cleaning solution to dry before collecting the sample.
- Turn the water on full force and let it run for 2 minutes or until the pump starts running.
- Reduce the water flow to a small stream, then take the sample.
- The sample should be collected within 24 hours of submission to ensure accurate results.
It is best to collect the sample on the day it is submitted. Keep the sample cool and transport it to the drop-off location in an ice chest as soon as possible after collection.
“We encourage you to bring samples from all wells on your property,” Pigg said. “Also, many participants who have water treatment equipment take samples before and after the treatment to make sure the equipment is functioning properly.”
Each sample should be labeled with both its name and the well from which it came.
It is essential for those submitting samples to attend the follow-up meeting to receive results, learn corrective measures for identified problems and improve their understanding of private well management, Pigg said.
Well water contaminants, concerns
Pigg said 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 contain pathogens that can cause diarrhea, cramps, nausea or other symptoms.
The presence of nitrate-nitrogen in well water is also a concern. Nitrate-nitrogen levels of 10 parts per million is considered unsafe for human consumption, he said.
“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,” Pigg said. “Infants less than 6 months of age and young livestock 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.
