Officials with SIRWA (the Southern Iowa Rural Water Association) say that as of today (Tuesday, August 12th), the Boil Water Advisory remains in effect for customers in NW Adams, Montgomery, SE Cass Counties and the Cities of Grant, Carbon, Brooks, Bridgewater and Lyman; account numbers beginning with 047, 048, 081, 082, 084 and 005. If you have any questions, call 641-782-5744.![NW_Adams_SE_Cass_Map jpg](http://www.kjan.com/wp-content/uploads/2014/08/NW_Adams_SE_Cass_Map-jpg-231x300.jpg)
SIRWA customers who have been under the Drinking Water Advisory are supplied with water produced by the Corning Municipal Water Department. Currently, the Corning Municipal Water Department uses chloramines for disinfection of the drinking water. Chloramines are created by combining chlorine and ammonia. They are conducting a free chlorine burnout of their water distribution system. The Corning Municipal Water Department will be using free chlorine as their disinfectant for approximately the next 30 days.
Officials hope the free chlorine can be distributed throughout the SIRWA distribution system being served by the Corning Municipal Water Department by the weekend and the Drinking Water Advisory may be lifted at that time.
SIRWA customers may notice open flushing hydrants throughout the SIRWA distribution system during this period and possibly overflowing water storage towers. The flushing hydrants will be opened to allow flushing of the system to help remove sediment from the pipes and distribute the change in disinfectant. Overflowing water storage towers further aid in the flushing process.
Possible Noticeable Effects: It is important to understand that during this temporary change there may be some discoloration or cloudiness in the water and possibly a slight chlorine odor or taste. If this is experienced you may want to run the water through the tap until it clears. Minor pressure fluctuations and small air pockets may also occur. Hydrant flushing should remove a majority of the color and odor, but some may reach customer lines during the process.
Customers who use tap water for kidney dialysis at home should consult their doctor to advise them if any changes are necessary in their residual disinfectant neutralization procedures. Customers utilizing the water for aquariums should monitor both free and combined chlorine residuals.
