Microbiological and physicochemical quality of some water points in the Nkolafamba Subdivision (Center Region, Cameroon)

A study was carried out with the objective of evaluating microbiological and physicochemical quality surface water in Nkolafamba subdivision, Center Region Cameroon. Five sampling points were selected based on several criteria. The bacteria isolated Mesophilic Aerobic Heterotrophic Bacteria (BHAM), that witnesses to faecal contamination Pseudomonas. Some abiotic parameters measured using usual techniques. results show some such as temperature almost constant around 25 °C during period. There is also a pH which tended towards neutrality de (7,04 ± 1,03 U.C). However, it noted stations are quite oxygenated (63,96%). Bacteriological analyzes revealed an average value 5.17 units (logUFC / 100mL) recorded for BHAM. Overall, abundances total coliforms averaged 4.18 100mL). waters harbor pathogenic microflora, P. aeruginosa pasteurella, abundance can sometimes reach 5,462 (log CFU These germs be cause eye infections or septicemia users these waters. have high bacterial load, pollution observed predominantly animal. pH, electrical conductivity, Suspended Solid (SS), nitrates turbidity influenced distribution germs. degradation favoured by their proximity sources pollution, runoff contaminated stations. waters, without any treatment, not recommended human consumption according standards World Health Organization.Keywords: Abiotic variables, coliforms, streptococci, bacteria, rivers.
