GROUNDWATER QUALITY ASSESSMENT OF CHILANCHIL ABAY WATERSHED: THE CASE OF BAHIR-DAR CITY WASTE DISPOSAL SITE

Improper dump sites have served many years as an ultimate disposal site for all types of waste; municipal solid waste, industrial sewage and hazardous waste in developing countries such Ethiopia. Physical, chemical biological processes interact simultaneously to bring about the overall decomposition wastes (chemically laden leachate). If not, deal properly, kind dumping can cause pollution groundwater (because Leachates) surface water (through contaminant transportation by flooding movements). Therefore, this study investigates spatial temporal variation quality within Chilanchil Abay watershed during dry wet season due Bahir Dar city. Water samples were collected from 6 sampling points 30th March 20th August a monthly period. Over 10 parameters pH, TDS, Electrical conductivity, Turbidity, Temperature, DO, BOD, COD, TC, NO3- PO43–, analyzed. Moreover, status area was evaluated Canadian Quality Index. Based on result model sample throughout raged 42 46.2 (marginal status).
