LEACHATE, GROUNDWATER, SURFACE STREAM, TREATED WATER AND SOIL CHARACTERISTICS OF THE VICINITY OF A MUNICIPAL SOLID WASTE DUMPSITE AT UYO METROPOLIS, AKWA – IBOM STATE, NIGERIA.

These findings documented the physical, chemical and heavy metal contents in leachate, borehole water, surface stream, treated water and soil samples around the municipal solid waste dumpsite at Uyo metropolis, Akwa-Ibom State, Nigeria. Samples were collected during the wet and dry seasons 2010/2011. The samples were analysed for the following parameters: heavy metals (Fe, Cu, Mn, Zn, Cr, Cd, Pb), anions (PO34,SO2-4,Cl-, NO-3, NH+4-N), essential metals (Na, K, Ca, Mg), total dissolved solids (TDS), dissolve oxygen (DO), Chemical oxygen demand (COD), pH, salinity, turbidity and conductivity. The results revealed that most of the parameters recorded for the leachate samples significantly exceeded the WHO international standards for drinking water in both seasons. Fe (47.33 and 113.13mg(L), Cd (2.29 and 14.47mg/l), Cu (5.78 and 35.87mg/l), Cr (1.63 and 7.63mg/l), Pb (12.33 and 31.13mg/l), Zn (17.33, and 34.5mg/l), BOD (52.2 and 159.6mg/l), Cl- (284.37 and 536mg/l), NO-3 (74.03 and 87.83mg/l), TDS (1709.5 and 2043mg/l) and DO (1.73 and 2.73mg/l). In leachate, all the heavy metals, Cl-, COD, salinity, and conductivity contents showed significant increase (P
