Abstract: This study examines the effects of human activities on water quality in Lamingo dam, field study was carried out to ascertain how human activities affect the quality of water of the dam between 2013 and 2014. The analysis carried out included physico-chemical analysis. Surveys were carried out to find out from the inhabitants their daily occupation and other activities normally undertaken around the reservoirs that might affect the water quality, the survey identified some of the activities the inhabitants undertook as farming, fishing, cement blocks moulding, cattle rearing, car wash etc. The laboratory results of water samples collected from the dam revealed that the level of total suspended solids (TSS), total dissolved solids (TDS), pH, dissolved oxygen ( DO), chemical oxygen demand (COD), temperature, electrical conductivity, turbidity, hardness, benzene, cyanide, mercury and cadmium in the water sample were quite high. With the exception of pH , all other physico-chemical parameters measured are between 100% and 120% higher and have exceeded the maximum permissible limit given by the National Standard Water Quality (Nigeria) and World Health Organization (WHO). Presence of some of these pollutants, at various points of the dam, was observed and level of these pollutants at varying degrees was found. These and other high levels of some of the parameters were attributed to poor sanitation, improper farming methods such as excess use of fertilizers, improper fishing practices and discharge of domestic waste into the dam.
