“…Also, Olatunji et al (2015) reported the suitability of groundwater quality for drinking based on their study in Ilorin metropolis, Nigeria. Balogun and Adegun (2013) reported the high concentration of EC, TDS, Cl, and trace metals in their study around Igando. A similar study by Yidana and Yidana (2010) asserts that the WQI of the Voltaian sedimentary basin in Ghana is suitable for drinking purpose.…”

“…Groundwater quality can be influenced by the lithology, water-rock interaction, and changes in space and time (Todd and Larry 2005;Srinivasamoorthy et al 2008;Bhattacharya and Bundschuh 2015).The continuous rise in anthropogenic activities, uncoordinated development, has led to an increase in point source pollutants such as leachates from dumpsite, seepage from the septic tank, and municipal sewage plants among others. Current emerging pollutants from agro-based activities such as nitrate, pesticides, and other heavy metals and persistent organic products (POPs), volatile organic carbon (VOCs) among others pose serious challenges to human health and the sustainability of groundwater (Kumazawa 2002;Jalali and Kolahchi 2008;Balogun and Adegun 2013;Salami and Susu 2013;Ocheri et al 2014).…”

Integrated approaches of water quality indices, multivariate statistical analysis, and geostatistical technique were applied to examine the groundwater quality and hydrochemical processes in Lagos, Nigeria. Fifteen samples each were randomly collected from peri-urban, rural, and urban settlements totaling 45 samples from protected dug wells during dry and wet seasons. Samples were analyzed for physicochemical parameters, anion, and cation using standard method. The result shows that 95.6% of the samples during the dry season had pH below the minimum guideline for drinking water. Factor analysis explained 73.5% and 84.2% of the variance during dry and wet seasons, respectively, and extracted two factors-salinity and weathering of minerals. Gibbs plot indicates rock-weathering process as the mechanism controlling the groundwater system. Drinking water quality index shows excellent quality. Revelle index indicates that 6.6% of the samples are strongly affected by salinity during the wet season. One-quarter of sample indicate very severe corrosion based on the water stability index in both seasons. The Piper's plot delineated four facies with primary hardness and mixed waters being the dominant during the dry and wet seasons, respectively. The study concludes that the groundwater is suitable for drinking. The study contributes to knowledge in the mapping of groundwater salinization and water stability indices and delineation of water types for information dissemination with a view to ensuring effective groundwater quality management. A policy that will ensure adequate protection of groundwater pollution from leachates, salinity, and anthropogenic impacts was recommended for sustainable groundwater use in the region.

“…Groundwater is an essential resource that requires sufficient protection from human-induced pollution sources. Human actions and resultant climate change have affected the standard quality of both surface and underground water [1], [2], especially from newly uptake pollutants through agricultural processes, nitrate, pesticides, other heavy metals and organic products, and volatile organic carbons; are a potential danger to human health and groundwater sustainability [3], [4], [5], [6], [7]. Among other water sources, groundwater is a source of fresh water and a dependable means of water provision in Nigerian communities and was considered less contaminated by pollution to surface running waters [8]; earth's surface groundwater quality relies on other factors:-the quality of inflow water, precipitation, rural-urban dumpsites and landfill systems and significantly, the form of sewerage systems adopted in the population [9] of Nigeria's municipal wastewater treatment systems are not adopted estates and landlords have their installed domestic wastewater platforms.…”

Groundwater is an essential resource that requires sufficient protection from human-induced pollution sources, assessments of water quality is an essential tool for water resources management strategies. the Physicochemical parameters measured were Hydrogen ion concentration (pH), Temperatures (oC), and electrical conductivity (EC), total bacteria and faecal coliform counts (Tb/fcc) were determined using the membranefiltration method; pH values was measure using a pH meter (Hach), the pH meter sensitivity was determined using buffers with a pH of 4.0 and pH of 9.0 and electrical conductivity values were taken, the TDS, total dissolved solids, measured using a meter; the SO42-, Fe2+ and NO3- were determined using Hach DR/2000 spectrophotometer. The water sampled temperatures range between 25.80 °C and 27.90 °C and arithmetic mean of 25.85 °C. The pH values of sampled wells and boreholes were in the acceptable pH range of 6.5 – 8.5, electrical conductivity values measured from the samples ranged from 94 μS per cm to 1418 μS per cm, having an arithmetic average of 370 μS/ cm; it is just one well that exceeded the permissible limit of 1000 μS per cm. The Total Dissolved Solids values ranged from 73 mg per Litre to 528 mg per Litre, an arithmetic average of 370 mg per Litre. The maximum value of 528 mg per Litre from zone B exceeded the acceptable limit of 500 mg per Litre. The concentrations are from 5 to 27×10 cfu / mL for total coliform counts and 0 to 12×10 cfu / mL for E. coli.77.2% of the samples fall within BOD values >3 mg per Litre, and 32.8% had BOD > 5 mg per Litre, signifying biogenic pollution and a possible seepage of mildly treated wastewater from sewage tanks near the wells. BOD and the bacteriological studies, for assessing biogenic pollution in water, indicated water samples are contaminated with wastewater.

Aquifer vulnerability using geophysical and physiochemical methods in parts of Ethiope West Local Government Area of Delta State, Nigeria

Supply of potable water in Oghara communities in particular and parts of Ethiope West Local Government Area of Delta State in general is inadequate as a result of increasing population and development activities in the area. This can be resolved and sustained if groundwater resources are effectively managed. This study was carried out to determine the aquifer vulnerability and groundwater quality using geophysical and physiochemical methods in parts of Ethiope West Local Government Area, Delta State. Thirty vertical electrical soundings and four dipole–dipole profiling were administered using Abem Terrameter SAS 1000 AB. The field data were curve matched and iterated using WinResist and Dipro software. The aquiferous zone was found in the fourth layer with resistivity ranging from 159 Ωm to 100234 Ωm, thickness ranging from 12 m to 156 m, and depth ranging from 32 m to 162 m except VES 25, whose aquifer is in the third layer. The dipole–dipole resistivity structure shows low resistivity values along areas where waste dump was sited with resistivity ranging from 300 Ωm to 630 Ωm. This finding suggests that the leachate from the dumpsite is affecting the characteristics possessed by the subsurface close to it. The first order geoelectric and Dar-Zarrouk parameter study of aquifer protective capacity revealed a protection capacity value less than 0.1 for VESs 1–18 and 20–30, while VES 19 revealed a value of 0.24. Thus, Oghara communities are extremely unprotected, and the aquifer is prone to contamination. The physiochemical analysis carried out indicates that groundwater is slightly acidic with a pH value ranging from 5.40 to 6.40 when compared with the WHO permissible limit. The groundwater flow direction is depicted from the east to the west; this will assist policy planners to decide where dumpsites and companies generating waste could be sited to preserve groundwater potential.
