A water quality index provides a single number that expresses overall water quality at a certain location and time based on several water quality parameters. The objective of an index is to turn complex water quality data into information that is understandable and useable by the public. Eight most important parameters such as pH, total dissolved solids (TDS), total hardness, calcium(Ca), magnesium (Mg), total alkalinity, dissolved oxygen (DO) and electrical conductivity (EC) were taken for the calculation of WQI. The WQI values for the River Ravi ranged from 54.8 to 97.88. The values of WQI showed that the water was free of any impurities at the sampling site except for 2-3 months where its values were less than 70. Whenever there are human activities e.g., dam operations, water gets polluted to some extent, so the value of WQI decreases. It was found that the parameter which is required in least amount contributes a high statistical value to the index. It is concluded that WQI can be used as a tool in comparing the water quality of different sources. It gives the public a general idea of the possible problems with water in a particular region. The indices are among the most effective ways to communicate the information on water quality trends to the public or to the policy makers and water quality management.

The study was carried out in the months of May- September 2005 and November-April 2006. The study made use of the random sampling technique for the administration of questionnaires. Along side the administration of the questionnaire, some selected Participatory rural Appraisal (PRA) tools were employed. Results revealed that, Fuel wood (FW), Kerosene (K), Sawdust (SD), Cooking gas (CG), Charcoal (CH), Rubber (RB), Electricity (EL), were the main energy types/sources identified in the Buea Municipality. Saw dust and Fuel wood were found to be the most frequently consumed energy type/source in the Buea Municipality with a resultant effect on deforestation. On an aggregate weighting, the area was found to consume a total of about 253m3 of FW, 744Litres of K, 14602Kg of SD, 6360Litres of CG, 20625Kg of CH, 3861g of RB, and 40,299KW of EL in a month. Monthly total household expenditure on the various energy types/sources for the study area was evaluated at about 10496640 FRS CFA (US$ 20993). The quantity supplied and consumed of the identified energy types/sources were observed to be adversely affected by income levels of consumers, market prices for these energy types/sources, seasons and the disappearing forest.
