Text Appearing Before Image:
e shut down for nearly 5 hours and measurements made atfrequent intervals during this period. The rising curves obtained aresimilar to those of 1910, which place the static head at approximately 102feet above city datum; this is for the wells at the pumping station. It was found that the specific capacity, or the yield under one foothead, of the Potsdam wells had decreased greatly since 1891. This isshown by the following table by Prof. C, S. Slichter contained in the1910 report of the Rockford water commission. Professor Slichter does not consider that the reduction in specificcapacity is entirely due to the mechanical clogging of the water-bearingsandstone in the vicinity of the wells. He believes that much of theclogging is because of the growth of low forms of plant life in the poresof the rock in the walls of the well, supported by the carbon dioxideliberated as a result of the reduction in pressure. 232 AETESIAN WATERS OF NORTHEASTERN ILLINOIS Specific capacity of Rockford wells
