2 <br />0 constituents as natural products of the weathering of min- <br />erals. If the nature of these weathering reactions is more <br />understood, then perhaps control procedures which limit <br />those reactions can be used. Abatement methods which stop <br />the pollution from occurring will decrease the need for <br />waste water treatment facilities for a mining operation. <br />Many of the abatement procedures which are suggested in the <br />EPA documents (2) are the same as those which are suggested <br />here, the difference being that the scientific basis for <br />those procedures will be more fully explained in this guide. <br />Besides the EPA documents, other texts and reviews have <br />been used for background information. The general texts by <br />Stumm and Morgan (6) and by Hem (7) are useful summaries <br />of the properties and chemistry of water. Reviews specific <br />to mine drainages that are of <br />(8), Moran and Wentz (9), and <br />Symposium, No. 18 (10). Some <br />on Front Range Mine drainages <br />(11, 12). <br />The analytical procedure <br />interest are those by Wentz <br />the American Water Resources <br />of the results of the studies <br />have already been published <br />s that have been used in this <br />research have been those suggested in the Standard Methods <br />Manual for Water and Wastewater (13) or the U.S. Geological <br />Survey water analysis manual (14). The methods of collection <br />and analysis specific to mine drainages have already been <br />published (15). Monitoring procedures will be discussed in <br />a later section and the analyses required to do that monitor- <br />ing will be more fully explained in that section.
