An "Xli in the matrix indicates that the type of con- <br /> <br />trol method is generally applicable to the activity source. <br /> <br />Table VII-l provides a further breakdown of the options available <br /> <br />within each class of control and implementation methods. These ap- <br /> <br />proaches include both technological and management controls and eco- <br /> <br />nomic, legal, social, and educational implementation possibilities. <br /> <br />Working from a detailed breakdown of problem sources, and using <br /> <br />Table VII-l as a guideline, various methods for control of these sour- <br /> <br />ces are identified in Appendix VII-A. Problem sources and control <br /> <br />methods for the following pollutants are contained in the Appendix: <br /> <br />Salinity <br />Sediment <br />Nutrients <br />BOD, DO, SS <br />Temperature <br />Heavy Methods <br />Radio Acti vity <br /> <br />The structure developed in the Appendix is used as a basis for <br /> <br />problem analysis, and in identifying subbasin (geographical) location <br /> <br />and distribution of problem types, and developing impact issues for <br /> <br />further study in the analysis phase of the project. <br /> <br />AGRICULTURAL TECHNOLOGY CONTROLS AND RESPONSE <br /> <br />Salinity Control Technology for Irrigation <br />Return Flows <br /> <br />The irrigation technologies available today have been developed <br /> <br />13 <br /> <br />-,'- <br />
