Assessment of Monthly Variation of Some Physicochemical Properties of Gosa and Kuje Dumpsites in Abuja, Nigeria

The indiscriminate dumping of hospital, industrial and some toxic waste in open dumpsites without proper disposal technique alters the physico chemical properties of the soil. Baseline information on the contaminant effects on soil from open dumpsites will go a long way to effectively pave the need for engineered landfills in the FCT. To evaluate some physiochemical properties of the dumpsites soil, one way analysis of variance (ANOVA) test was used to compare the averages of the physico chemical parameters for significant differences. Results revealed that temperature varied significantly (p less than 0.0005) from one depth to another; other physicochemical parameters however had no readily discernable pattern of change with respect to depth and varied insignificantly from one depth to the other. it was observed Soils at the disposal sites showed high pH, TDS and EC regime in comparison to control sites. Soil samples collected from the dumpsite showed variation in physico-chemical parameters with pH (7.7-8.5), EC (311-507), Temp. (25.9-30.4) 0C and TDS (153-252) mg/L and pH (7.2-8.4), EC (135-681), (Temp. (24.3-28.9) 0C and TDS (88-370) mg/L respectively.
