Predicting Future Demands for Water

“…The industrial subsector includes water used for ''industrial purposes such as fabrication, processing, washing, and cooling, and includes Table 1 Examples of water production and purchase data by public water supply systems in selected communities in Northeastern Illinois in 2005 such industries as steel, chemical and allied products, paper and allied products, mining, and petroleum refining,'' and the commercial subsector includes water used for ''motels, hotels, restaurants, office buildings, other commercial facilities, and institutions'' (Avery, 1999). The industrial subsector includes water used for ''industrial purposes such as fabrication, processing, washing, and cooling, and includes Table 1 Examples of water production and purchase data by public water supply systems in selected communities in Northeastern Illinois in 2005 such industries as steel, chemical and allied products, paper and allied products, mining, and petroleum refining,'' and the commercial subsector includes water used for ''motels, hotels, restaurants, office buildings, other commercial facilities, and institutions'' (Avery, 1999).…”

“…A similar age and material classification of aquifers was used by the ISWS for a ground-water quality summary of Illinois (Gibb and O'Hearn, 1980). The agerelated aquifer classification also has been used by the ISWS for water-use reports (Kirk, 1987) and the USGS (Avery, 1995).…”

“…The largest freshwater withdrawals in Illinois, excluding the Chicago area, are in the LIRB. In 1988, the total freshwater use for the LIRB, including surface and ground water, was 4,100 Mgal/d (Avery, 1995). Surface water is used mostly for thermoelectric power.…”

“…Surface water is used mostly for thermoelectric power. Ground water is used mostly for community supply and irrigation (Avery, 1995). Other uses of ground water, in order of most to least use, include self-supplied industrial, self-supplied domestic, self-supplied livestock, and self-supplied commercial and mining.…”

“…Other uses of ground water, in order of most to least use, include self-supplied industrial, self-supplied domestic, self-supplied livestock, and self-supplied commercial and mining. Avery (1995) More than one-half of the drinking water in the LIRB is from ground water. In 1988, the total community-supply delivery was 190 Mgal/d, of which 108 Mgal/d or 57 percent was for domestic use.…”
