San Angelo Water Disinfection Change for June
The City of San Angelo’s Water Utilities Department has temporarily changed the method of disinfection used in its public water supply.
The Water Department normally uses chloramine, a mixture of ammonia and chlorine, to disinfect water. Starting this past Saturday, and for approximately four weeks after, the Water Department will be using chlorine only, also known as “free chlorine.” The periodic and temporary conversion from chloramines to free chlorine, which is a normal procedure for water systems, ensures water safety in distribution lines and the highest quality of drinking water.
Free chlorine is a stronger disinfectant than chloramine. As a result, water users may experience a slight change in the aesthetics of their water during the conversion, including a noticeable “chlorine odor” and slight discoloration. Most symptoms should lessen after a couple of weeks and do not affect the safety of the water supply.
The Water Utilities Department encourages kidney dialysis patients to speak with their equipment supplier; different types of equipment may have varying needs and require adjustments. The City has contacted local hospitals to alert them of the change.
The processes most aquariums have for removing chloramines from water should do the same with free chlorine and need no adjustments. Even so, fish tank operators are encouraged to confirm that with their equipment supplier. Local pet stores have also been informed of the conversion.
The Water Department will monitor chlorine levels and water-quality standards in the distribution system on a daily basis to ensure the safety of the water and that all state and regulatory standards are met.
