Constituents of Leachate Generation and Migration in Ministry of Agriculture Forest Nursery Open Dumpsite in Jos Plateau State, Nigeria

Abstract

The constituents of leachate generation and migration in ministry of agriculture nursery open dumpsite in Jos Plateau were determined. Leachate extraction from solid waste (SW) was carried out. Test dumpsite soil with different elevations. Elevations were with uniform density. Representative solid waste dumpsite soil sample were collected from one dumpsite. The collected SW soil subjected to column experimental test, results showed physicochemical parameters (pH, TSS,TDS and EC) range of descriptive value in terms of histogram values of 5.66 – 8.23(1.0m to 1.5m depth) pH, 90.65 – 1125.96mg/l (0.5 to 2.0m depth) TSS, 17.78 – 156mg/l (1.5 to 0.5m depth) TDS, 9.02 – 80.01 us/cm and principal component summary analysis. The histogram and principal component summary values increase. Alkalinity has highest concentration, followed by hardness which has least, BOD5 has lower values, followed by COD which has higher value, Cl−increasing, S04 2-, N03 values increases, P04 in waste decreases with increase time and depth. The Na+, increasing K+ second to Na+, increases, Mg2+ and Ca2+ in MSW increases as time and depth proceed. The results of Cu, Fe, Cd and Pb in histogram had moderate to high values. All were examined for physicochemical, alkalinity and hardness, BOD5, COD, anions, cations and heavy metals to study the seasonal variation of significant parameters. The results from the leachate analysis were used as a tool to identify the processes and mechanisms affecting the soil and water chemistry from the study area.
