The Texas Well Owner Network, TWON, is hosting three upcoming events in the Texas Panhandle Sept. 17-18 for residents to have their well water screened.
Joel Pigg, Texas A&M AgriLife Extension Service program specialist and TWON coordinator, Bryan-College Station, said the 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.
There will be a $15 per sample cost for the water well screening.

Sampling instructions
A water sample form must be completed for each sample submitted. Follow the directions below for sample collection. (See twon.tamu.edu for a printable version of the collection instructions and the sample information sheet.)
• Pour the contents out 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 to the wellhead. Remove the water
hose if one is present and take the water directly from the spigot/hose bib.
• If an inside faucet is used, remove the aerator on the faucet before making the
collection. Rinse and dry the exterior of the faucet to prevent contamination of the
water sample.
• If possible, wipe off with a Clorox-type towelette or paper towel wetted with a light
bleach solution to kill any bacteria present on the faucet. Allow the cleaning solution
to dry before sampling.
•Turn the water full force and let it run for 2 minutes or until you hear the pump start
running.
•Reduce the water flow to a small stream, then take the sample.
Refrigerate the sample and transport it to the drop-off location in an ice chest as soon after collection as possible. It is best to collect the day the sample is submitted. Otherwise, make sure the sample is kept cool and out of direct sunlight. The sample should be collected within 24 hours of submission to ensure accurate results.
“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 your name, and if you bring more than one sample, the label should indicate which well the sample came from.
Private water wells should be tested annually, he said. The samples will be screened for contaminants, including total coliform bacteria, E. coli, nitrate-nitrogen, arsenic and salinity.
Pigg said it is essential for those submitting samples to be at the appropriate follow-up meeting to receive results, learn corrective measures for identified problems and improve their understanding of private well management.
Well water contaminants, concerns
Pigg said that 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,” 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, in partnership with the AgriLife Extension offices in Childress, Motley, Cottle, Haredman, Foard, King, Donley, Collingsworth and Hall counties. Additional support provided by Gateway GCD, Mesquite GCD.
Funding for TWON is through a Clean Water Act 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, a Texas A&M AgriLife Research unit that combines expertise across The Texas A&M University System.
