The Ayensu River plays very important roles in the lives of the inhabitants living within and beyond its catchment. The Ayensu River has however received relatively little attention in the field of research and it was against this background that this research was conceived, to generally assess the quality of the river water and to investigate the various human activities that impact negatively on the river water quality.

The rational for the research was to assess the quality of treated water supplied to the western part of Accra by the Weija Headworks. The quality of water treated at the headworks before distribution and that of selected households were assessed.

The study involved analysis of water samples from wells, salt pans and lagoons as well as soil samples in the proximity of areas in communities where small-scale salt mining activities is undertaken in the Komenda-Edina-Eguafo-Abrem (KEEA) District.
