Kempner Water Supply Corp. announced Wednesday it will convert its disinfectant used in the distribution system from chloramine to free chlorine from June 14 through July 14.
The decision comes after KWSC members expressed concerned about a greenish tint to their water. KWSC General Manager Bruce Sorenson said the switch should help remedy the issue.
“When we use the chloramine, chloramine lasts longer in the system and is more effective for a longer period,” he said. “But free chorine is way more effective.
“We have an issue with water right now in the lake,” Sorenson added. “The water you see going down the river that is green is what is in the lake. It is hard to treat green water.”
Sorenson noted the Texas Commission on Environmental Quality says water with a color is fine to consume. He said even microfilters struggle to filter out the green color, but free chorine will assist in destroying it.
“What we’ve noticed is if we treat the water coming out of the plant, it is crystal clear,” he said. “As it loses its chlorine residual, the color comes back.”
Extra debris from the heavy flooding that occurred during May is what has led to a greenish color in area creeks and rivers which ultimately flow into Stillhouse Hollow Lake, the production site for the KWSC.
The water supplier tells customers that during the disinfectant change, “you may notice a slight change in the taste or smell of your water. These changes are normal and do not affect the safety of your water. The water remains safe for drinking, cooking, bathing and other household uses.”
Those with questions should contact KWSC at 512-9323701 or email info@kempnerwsc.com.
Sorenson said he expects the water to return to normal in the next two weeks after implementation of the chemical switch.
