The cost of the screenings is $15 per sample. Water samples will be screened for contaminants, including total coliform bacteria, E. coli, nitrate-nitrogen, arsenic and salinity. 

“The TWON program serves residents who depend on household wells for their water needs,” said 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.

“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 can be dropped off at the following locations on July 20 from 8:30-10 a.m.:

  • Brewster County: AgriLife Extension Office for Brewster-Jeff Davis County, 2101 Farm-to-Market Road 1703, Alpine; or Brewster Groundwater Conservation District, 201 W. Ave. E, Alpine.

The rainwater harvesting will be a part of this program.

Sampling instructions

Those submitting samples are asked to follow the water sample instructions available at twon.tamu.edu. A water sample form must be completed for each sample.

In partnership with the AgriLife Extension offices in Brewster, Jeff Davis and Presidio counties, the screenings are presented by AgriLife Extension and the Texas Water Resources Institute, a unit of Texas A&M AgriLife Research that combines expertise across The Texas A&M University System
