Noatak, Alaska, United States


Low water on the Noatak River may be the reason behind changes in the water quality in community wells. The water quality began to change in the plant as measured (eventually) by the need for twice as much chlorine and Naclo polymer in order to get an acceptable residual of chlorine. The change indicates that the well recharge had been depleted and the that wells began operating on stored water in the aquifer. This water would have been older, likely anaerobic and higher in organics and in inorganics such as iron and manganese.
