Evaluation of surface water quality for domestic and agro-industrial applications along the tropical rainforest gradient, central Cameroon

The primary water supply to the inhabitants of the tropical rainforest is surface water with limited water quality data. A hydrogeochemical study was conducted to identify the processes that control surface water chemistry and to examine the quality of water sources for domestic and agricultural purposes. In the two seasons, fifty-six water samples were collected from rivers within the study area. The primary ions and...

Water quality analysis in Manoka Island and Youpwé, Douala, Cameroon: Hydrogeochemical and bacteriological perspectives

This study investigates the water quality of surface and groundwater sources in Manoka Island and the Wouri estuary (Youpwé), areas significantly impacted by urbanization, industrial activities, and agriculture. Physicochemical parameters (pH, EC, TDS, temperature, and salinity) were measured on-site, and 50 samples (13 boreholes, 29 hand-dug wells, and 8 surface water) were analyzed for major ions using...

Growth response of anguillid eels in two Kenyan rivers with varying levels of habitat integrity

Eels of the genus Anguilla have a unique life cycle that involves long migrations between freshwater and marine environments, making a significant contribution to biodiversity and fisheries. This study examined the growth and health of Anguillid eels in two Kenyan rivers with differing habitat integrity; the Ramisi and the Athi-Galana-Sabaki (AGS) Rivers. Four species which are the Anguilla bengalensis, Anguilla...

Calibration of the Hargreaves and Priestley-Taylor equations for estimating reference evapotranspiration in the Densu River Basin in Ghana

Reference evapotranspiration (ETo) defines the maximum evapotranspiration that can occur in a basin. Its accurate estimation is therefore very important in accurately estimating how much water is available in any Basin for use since the actual Evapotranspiration (AET) that occurs depends on the ETo estimated. AET is a parameter that is difficult to measure on the field and therefore is mostly estimated from ETo....
