Abstract
This study examined the impact of leachate on ground and surface water quality in Lemna District of Calabar Municipality in Cross River State – Nigeria. Water samples were collected from both surface and groundwater source for physico-chemical and bacteriological analysis. The results showed the mean values of the measured parameters to be: pH = 6.2, Electrical conductivity = 63.38, temperature = 24.43, BOD5 = 1.08, Do = 5.35 and Zinc = 0.08. Others were coliform = 166.00, turbidity 24.50, lead 0.097 and total hardness = 30.73. The statistical analysis revealed significant differences between the measured parameter of BOD, Do, coliform, zinc, iron, turbidity, potassium, nitrate, copper, total hardness and sodium and the WHO minimum permissible standards for the above measured variables. It was concluded that surface and groundwater in the study area has been significantly affected by leachate. It was recommended that open dumpsite should be sited away from streams and groundwater aquifers that are used for domestic purposes.
