In response to questions from the Pinedale Roundup to the
E.P.A.(Environmental Protection Agency) in regards to the Pinedale Water
System's recent violation, the E.P.A. sent the following letter:
Stephen-- thanks for the follow-up inquiry regarding the Pinedale
drinking water system. I want to emphasize that The Town of Pinedale has
been cooperative and quick-to-act in response to EPA’s Notice of
Violation (issued on October 17) regarding the use of the EPA-approved
corrosion control treatment technology at the water system. The
approved treatment is back on at levels that will help mitigate
corrosion and lead in drinking water and EPA is satisfied that this
matter has been addressed. As you may know, last month, the Pinedale
water system submitted its most recent reporting for lead and copper
which (based on the 90th percentile calculation of collected samples required by the Act) is below the Safe Drinking Water Act action level for lead.
has a long history of cooperation with EPA in delivering drinking water
in the community. While we regret any miscommunication or missed
opportunities to clarify drinking water requirements with local
officials, the Safe Drinking Water Act does require a clear set of steps
related to changing approved control technologies. Moving forward, we
are committed to maintaining clear lines of communication with operators
and local officials to make sure our collective efforts recognize local
needs and are consistent with the Safe Drinking Water Act.
Town’s current EPA-approved corrosion control technology is sodium
silicate. While other control technologies may be used, under the Safe
Drinking Water Act, water systems are required to conduct studies and
notify EPA in writing prior to making any permanent changes in
treatment. EPA must then review and approve these changes before they
are implemented. In this case, EPA was aware soda ash was being used by
system operators, however the intention to permanently replace the
approved sodium silicate corrosion control inhibitor with soda ash was
not made clear to EPA, nor were the appropriate bench studies done to
determine the effectiveness of this method. My understanding is that
EPA became aware that the sodium silicate was turned off permanently
during a sanitary survey in August 2016.
sampling of schools is not specifically required, the School District
is implementing a voluntary sampling program. I understand Gregg
Anderson of the Sublette County School District is leading this effort
and is in contact with the operators from Pinedale water system.
Hope this is useful.
A safe and happy Thanksgiving to you and yours!
USEPA Region 8
As stated in the letter, please be assured that your water is and always has been safe to drink.
