Economic Effects of Mineral Content in Municipal Water Supplies

Description: Report describing the application of conventional cost experience to physical features of source of supply, treatment, pumping, transmission, distribution, and storage for community water supply sources. Some costs due to readily removable water quality characteristics like suspended solids, color, taste, and order are measurable, as are other conventional costs of operation and maintenance. Other costs related to an excess of dissolved solids, however, tend to be unknown and are the subject of… more
