Industry with the <br />most effect on th~ water ~~ality of the Spring River nasin is in <br />the Joplin-Carthage area. Center Creek receives most of the <br />industrial waste discharged to the Spring River Basin. Waste dis- <br />charged from chemical industries to Center Creek have been and are <br />creating water quality problems in Center Creek. The l~rge ctuan- <br />tity of ammonia which is discharRed has, in the past, been respon- <br />sible for toxic conditions in the creek and are thought to be the <br />primary cause for oxygen deficits which are commonly found. The <br />water quality problem in Center Creek is quite complicated. Gen- <br />erally, though, only minor water quality control problems occur <br />from municipal and industrial effluents on interstate and intra- <br />state tributaries to the Grand (Neosho) River. <br /> <br />Agricultural wastewaters are not a significant basin wide prob- <br />lem but local complaints have been made to the Missouri Clean Water <br />Commission. In the Spring River Rasin alone, annually more than <br />180,000 caZSle are grazed and Some 35,000 tons of fertilizer are used <br />on lands. It has been reported that <br />appropriate water quality control is being initiated in areas which are <br />creating, or seem likely to create, pollution problems. For example, <br />under ?ublic Law 566 (U.S. Department of Agriculture) several small <br />watershed projects have been initiated whise should help to alleviate <br />sediment problems in the re~ion's streams. Silt is not a significant <br />water pollution problem in Missouri's interstate tributaries to the <br />Grand (Neosho) River. <br /> <br />Problems of pollution affecting both surface and f,roundwater <br />have persisted for many decades in the mined areas around Joplin. <br />The study in progress (Section 208 of P.L. 92-500) finds heavy metal <br />content of mine waters to exceed permissible levels for viable life <br />functions of aquatic organisms. Leachats from tailinR piles have <br />heavy metal cont~nt many fold greater than that of the min~ waters, <br />Hater from both sources discharge to streams, C~nter Creek being an <br />example. Stream bottom sediments are being investigated and high <br />lev~ls of h~avy m~tals ar~ beinR found along some stream seRments. <br />Improperly constructed de~p wells and w~lls which have become faulty, <br />permit polluted shellow groundwater to enter the deep aquifers. A <br />federally funded project of the 1930' s was the plugRing of all deep, <br />abandoned wells, which could be found. This has done much to Ruard <br />the quality of the deep ~foundwater. Unfortunately, not all abandoned <br />deep wells were located. <br /> <br />Hith larger populations and growing industrial centers and <br />the demand for water becoming Rr~ater, a number of alternatives <br />exis~ for the increase in the supply of water for the Newton- <br /> <br />100 <br />
