Seepage Interceptor Drains And Topsoil Salinity, T R. Negus

Journal of the Department of Agriculture, Western Australia, Series 4

The Department of Agriculture established 121 trials in its Narrogin advisory district starting in 1972 to measure the effect of bulldozer and grader built seepage interceptor banks and drains on the topsoil salinity of the land downslope of them.

The ideal system would generate no hazardous wastes in the first place but this, of course, is wishful thinking for highly industrialized societies. The next best or “preferred” solution is a system which emphasized reduction and recycling of hazardous wastes. The existing waste management systems in the world today, however, almost exclusively emphasize treatment and disposal. This thesis assesses the hazardous waste …
