Water Well Screening March 25th

Sharing is caring!

LINDEN — The Texas Well Owner Network is hosting a water well screening March 25 in
Linden to give area residents the opportunity to have their well water screened.
The screening will be from 8:30–10 a.m. at the Texas A&M AgriLife Extension Service office
for Cass County, County Office Building, 604 Hwy 8, Linden, Texas.
A meeting explaining screening results will be at 6:00 p.m. March 26 at the Cass County Law
Enforcement Training Center, 1031 CR 1913 in Linden.
The screening is presented by AgriLife Extension and Texas Water Resources Institute in
partnership with the AgriLife Extension office in Cass County.
John Smith, AgriLife Extension program specialist, College Station, said area residents wanting
to have their well water screened should pick up a sample bag, bottle and instructions from the
AgriLife Extension office in Cass County. Bottles and bags will be available at least a week
before the turn-in date.
“It is very important that only sampling bags and bottles from the AgriLife Extension office be
used and all instructions for proper sampling are followed to ensure accurate results,” Smith said.
The samples must be turned in by 10 a.m. on the day of the screening. The cost for each sample
is $10.
Smith said private water wells should be tested annually. Samples will be screened for common
contaminants, including total coliform bacteria, E. coli, nitrate-nitrogen and salinity.
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 present that can cause diarrhea, cramps, nausea or other
symptoms, Smith said.
“Water with nitrate-nitrogen at levels of 10 parts per million is considered unsafe for human
consumption,” Smith 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. Infants less than 6 months of age and young livestock are most
