Excerpt from Water-Supply and Irrigation Papers of the United States Geological Survey, 1899: No. 30 West Saginaw takes its water direct from the river, under a dock close to the heart of the city and near a large sewer, the settling tank being 75 by 22 feet and the river current variable. The water is of a muddy-green color, with a good deal of bark ﬂoating around in the tank. Alma takes water from a mill race 300 feet above a sewer. There is no protection to the banks of the stream above. Both of these places, however, use almost exclusively for drinking purposes water from deep wells which comes under clay and is therefore safe. In Saginaw it is said that the salt water from the deeper wells has found its way into some of the shallower rock wells and contaminated them, and the waste bitterns go into the river. But individual wells, however numerous, are not an ideal supply for a large town, with the running here and there to neighbors, the possibility of some wells being too shallow to be safe, and the liability to contamination from dug wells. The Saginaw is so sluggish a stream that it is practically a pond. A plant situated as far up as the East Saginaw plant, there fore, if the banks were bought for a riverside park and protected for a few miles, and if the reﬂux of water from the lower river were prevented, especially if there were a gravel bed instead of decaying planks between the settling tank and the river, might furnish a fairly satisfactory water supply; but one would probably not have to go far - not beyond Vassar - to secure an ample and pure supply in sand stone. Analyses of these waters will be given in a later paper. Most of the other large cities are supplied from the Great Lakes, and seem to find no objection to that source, though Chicago's experience shows that there is a possibility of danger to be guarded against.
