The Water resources of the NAR are presently being used for various and, in many instances, conflicting purposes. The use of these waters can generally be described within the following categories: municipal and industrial water supply, recreation, commercial fishing, commercial navigation, power generation, and irrigation. The major water bodies in the NAR Study Area in the vicinity of population and industrial centers are seriously degraded by pollution. Study Area is served by waste collection and treatment facilities. The Non-Industrial waste load before treatment is expected to nearly double by the year 2020 (43,800,000 P.E.'s vs. 86,600,000 P.E.'s). It is expected that this same loading after treatment will decrease through time due to increased treatment; from 16,000,000 P.E.'s to 9,760,000 P.E.'s. The 1960 Industrial waste load to the waters of the NAR Study Area is estimated at 67,033,000 P.E.'s before treatment which is reduced to 40,100,000 P.E.'s after treatment. See Table 6 for the breakdown of the present waste load by major water-using industry groupings. The total industrial waste load before treatment is expected to increase nearly ten-fold from 67,033,000 P.E.'s in 1960 to 624,000,000 P.E.'s in 2020. The industrial waste load before treatment in the year 2020 will amount to nearly 90% of the total load generated.
