Residents of Ardmore may have received a notice from the city about the quality of their drinking water.
The city notified residents Wednesday that the water supply did not meet EPA requirements for the total organic carbon treatment requirements during the 12-month period of October 2016 through September 2017.
Utilities Director Shawn Guerin said use of alternative supplies of water was unnecessary, though the notification sent out by the city did recommend anyone with specific health needs to consult their primary physician
“I’m baking, brushing my teeth and bathing with it,” Guerin said. “Nothing was found in the water. We just violated a rule.”
Latest calculations reveal that Ardmore did not remove the average percentage of organic carbon required by the Environmental Protection Agency. Ardmore met a removal ratio of only .95 of these organic compounds from area lakes instead of the EPA required 1.0 ratio.
The slight variation in acceptable ratio came from a bad batch of polymer the city uses to coalesce organic material in lakes for removal. Guerin said the poor quality of this batch in the past year caused standards to be merely a touch below expectations.
Various organic elements form a sort of blob at the bottom of bodies of water when city crews apply this polymer. Guerin said the polymer failed to compile the material as thoroughly as he would prefer.
So the only error in water purification comes from less-than-ideal chemicals used to purify water, according to Guerin.
Guerin also discussed the city’s plans for long-term water quality assurance.
A portion of Beard Street was closed Wednesday for the Public Works Authority to replace an old water line, which Guerin called a “dead end” line.
A dead end line means the water stops and is not cycled in a continuous flow through other water lines, so when water hits a dead end line it stagnates and some quality is lost. The old line was replaced with one that will continuously cycle water underneath the ground.
This small job is the first of several water lines to be replaced over the next decade with similarly functioning lines.
Several dead end lines are installed in the southwest region of Ardmore, Guerin said, and two to three of these line systems near Harvey and McLain Roads, spanning up to two miles,  are currently slated for renovation.
According to rough estimations, Guerin said these projects could reach up to $1 million each, but he said it is difficult to tell at this point in time with pending engineer designs and budget stipulations.
“What you want to have is a loop system,” Guerin said. “If not, water hits an end, goes stagnant and we have to flush water lines to get rid of old water. These will keep it circulating and moving.”
