Analysis of Groundwater Quality from Coastal Aquifers around Agbara Industrial Estate, Lagos, Southwest Nigeria.

Abstract

he quality of water is measured in terms of its physical, chemical and bacteriological characteristics. Groundwater in most coastal aquifers has deteriorated owing heavy anthropogenic interference with the hydrological cycle. The study revealed that the pH in the area is low and enhanced the high rate of microbial activity typified by elevated concentration of BOD. COD, total coliform and E.coli. They human and microbial activities affected the colour. The high concentration of manganese may be due to effluent from the industries within the estate which are discharge into the environment without proper treatment. The Piper diagram shows that the water type in the area in Na-Cl type indicating a possible marine source. Good sanitary habit and proper treatment of industrial effluent before discharge into the surrounding is advocated.
