<br />~. <br />o <br />f'v <br />o <br /> <br />. <br /> <br />The last assumption is most frequently taken. The Bureau of Recla""ation <br /> <br />. <br /> <br />has compiled a summary of many of the estimates in columns 2 to 8 of <br /> <br />Table VI- 5. <br /> <br />Using their estimates as shown in columns 9, 10, and 11 of Table <br /> <br />. <br /> <br />VI-5, the Bureau has estimated municipal damages on the basis of <br /> <br />the same set of assumptions as their agricultural damages in the <br /> <br />. <br /> <br />previous section. See Table VI- 6. <br /> <br />By comparison, Va lentine 19 estimated annual urban damages to be <br /> <br />$124,300 per mg/l for the year 2,000 when the salinity was projected <br /> <br />. <br /> <br />to be 300 mg/l greater than in 1970. <br /> <br />The EPA estimate was that municipal damages would increase to <br /> <br />$3, 564,000 annually by 2010. See Table VI-7. In their estimate, the <br /> <br />. <br /> <br />estimate for municipal damages reduces to <br /> <br />$3,546,000 <br />464 <br /> <br />= $7,642 per mg/l per year <br /> <br />. <br /> <br />whic)1 is much less than the USBR estimate. Again, the project entitled <br /> <br />"Salinity Management Options for the Colorado River" is designed to <br /> <br />. <br /> <br />provide some improved estimates of municipal damages, <br /> <br />Industrial Damages and Costs. The use of industrial water in the <br /> <br />Lower Basin areas where quality is a deterrent is primarily for cooling <br /> <br />. <br /> <br />and boiler feed. Minerals in boiler feed water causes scale formation <br /> <br />on heating units, corrosion in the system, and also affects the quality <br /> <br />of steam produced. In cooling systems, the mineral content affects <br /> <br />. <br /> <br />28 <br /> <br />. <br />
