Item ASSESSMENT OF A GROUNDWATER QUALITY FOR DRINKING PURPOSE IN ILORIN, NIGERIA(Faculties of Science and Engineering, Nigerian Defense Academy, Kaduna, 2016) Eletta, O.A; Adeniran, J.A; Adewoye, L.T; Adenle, A.AGroundwater is a major source of water supply in Nigeria where there is an inadequate supply of water for domestic, industrial and agricultural uses. This paper examines the suitability of water samples from a target hand dug well (TW) in a residential area in Ilorin, Nigeria for drinking purpose. The samples were characterized to determine physico - chemical properties over eight weeks due to the observed, oily, greenish blue water discharged from the groundwater source. Another well in the neighborhood was investigated as a control (C). Concentration of selected anions, cations and the presence of hydrocarbons were established in the contaminated well with focus on nutrients and hydrocarbons related to sewer, paint and petroleum compounds to establish the possibility of leakages from sewers, the auto repair/painting workshop and the petroleum products pipeline which are located uphill of the well. The results of physico -chemical characterization carried out on the TW showed pH:7.3 – 7.9; turbidity: 1.2 – 4.5 NTU; total hardness; 175.30 – 222.02 mg/l; TDS: 90 – 125 mg/l. Concentration of cations and anions ranged between 0.16 – 0.24 for Fe; Mn: 0.01 – 0.06; Zn: 0.18 – 0.45; NO32-: 5.95 – 12.76; SO42-: 192.1 – 235.85; Cl-: 230.63 - 283.32 all in mg/l. A Gas Chromatography Mass Spectroscopic analysis (GC-MS) carried out on the water samples from TW showed that, 24.83% of the peaks are within 90 – 100% quality range which confirms the compounds suggested from the installed NIST11 library are correct within minimal error limit.Item Energy recovery from municipal solid waste in Nigeria and its economic and environmental implications(Wiley Periodicals, Inc., 2019) Yusuf, R.O; Adeniran, J.A; Mustapha, S.I; Sonibare, J.AAn assessment of potential biomass resources inNigeria for the production of methane and power generation is presented in this paper. Nigeria, as an underdeveloped and populous country, needs an uninterrupted source of energy. The country's energy problems have crippled large sectors of the economy. The percentage of people connected to the national grid is 40%. These 40% experience electricity supply failure on average 10–12 hours daily. Energy generation from municipal solid waste (MSW) is an effective MSW management strategy. Yearly waste generation has increased from 6,471 gigagrams (Gg) in 1959 to 26,600 Gg in 2015. This amount is projected to reach 36,250 Gg per year by 2030. Methane emission for 2015 was 491 Gg, and it is projected to reach 669 Gg in 2030. These values translate to 3.48 × 109 kilowatt hours (kWh) of electricity for 2015, with a projected 4.74 × 109 kWh by 2030. The revenue to be derived from the electricity that is generated could have been US$365.04 × 106 for 2015, and it is estimated that it will reach US$473.82 × 106 by 2030. It was found that methane emissions from MSW increased with time, and capturing this gas for energy production will lead to a sustainable waste management.
