The City of Ames, Iowa, derives its water supply from a thirty foot sand and gravel stratum, lying between the depths of seventyfive and one hundred and five feet below the normal ground surface. The water is organically pure and is satisfactory as a city supply, except that it is somewhat hard about 16 grains and carries a high iron content. At the present time the water is aerated, but adequate storage is not available to give detention period sufficient to settle out the iron. Consequently, this settlement takes place in the mains and results in annoying discoloration whenever any unusual disturbance occurs in the mains. Frequent flushing helps, but the relief is only temporary. No treatment other than the aeration is given the water. It is tested on Tuesday and Thursday of each week and is always found satisfactory. Occasionally the Bacteria aerogenes show up, but the irregularity with which this occurs indicates contamination from some source after the water has left the ground. With the iron removed, the water would be entirely satisfactory as a supply, and its accessibility and abundance make the consideration of any other supply unnecessary. It is not, therefore, the supply itself that is causing the city administration concern, but rather the inadequacy of the wells, storage, and distribution system. The rapid growth of the city in the past few years has necessitated heavy outlay for new mains, hydrants, valves, meters, etc., all of which have been financed from the earnings of the plant, so that the ever increasing discrepancy between the demand and the storage, while not entirely overlooked, was at least neglected. Certain incidents have impressed on those directly in charge of the water supply the absolute and immediate need of strengthening the system, and in April, 1923, a special election was called to vote a $70,000 bond issue to carry out the needed extensions. This election was peculiar in that it carried by an overwhelming
