On July 20, 2018, at 6:00 a.m. East Rio Hondo Water Supply Corporation (PWS ID 0310096) and Arroyo City (PWS ID 0310031) will change our primary disinfectant from "Chloramines" to "Free Chlorine". The change in disinfectant is conducted to combat an aggressive algae bloom currently taking place in Cameron County Irrigation District #2’s raw water supply system that feeds our surface water treatment plants. We are currently working on an alternative treatment technique to treat the higher algae concentrations in our raw water and intend to implement this technique as soon as possible in order to limit the amount of time needed for free chlorination. Our goal is to revert back to chloramines next week. You will be notified as soon as possible when any changes are made. During this conversion process, both to and from free chlorine, a stronger chlorine/bleach odor may be apparent in your drinking water, as these odors are a product of the breakdown of chloramine by free chlorine. All regulatory requirements will be adhered to during this process in regards to the level of chlorine in your drinking water. E.R.H.W.S.C. advises any customers with medical conditions affected by Free Chlorination to consult medical professionals in regards to any affects concerning consuming chlorinated drinking water. If you have any questions, please contact Amanda M. Ramos, Administrative Services Manager at (956)247-7817.
