“…Nitrate and sulfate was determined using HACH DR/2000 direct reading spectrophotometer. Total solids and magnesium were determined by gravimetric and Atomic absorption spectrophotometer (AAS), respectively (Balogun et al, 2012). Water samples intended for chemical analyses were vacuum filtered through 0.45-lm nylon membranes.…”

A study was conducted to determine the biological, chemical and physical drinking water quality from shallow wells in agrarian communities. An insitu membrane filtration test kit was used to determine the microbiological quality of water and a photometer was used for the chemical analyses. Water samples were collected from protected shallow wells during wet and dry seasons of the year 2012 to determine the change in quality with different seasons. The results of the analysis show that Gapkan had the least value of pH of 6.7 while Lade had the highest value of 8.4. ANOVA (P<0.05) showed pH to be statistically higher during the wet season than in the dry season. The conductivity during the wet season was observed to range between 1210 µS/cm and 1678 µS/cm for Kpada and Gakpan communities respectively. Turbidity values during the wet season ranged between 4 and 7 NTU while dry season analysis ranged between 2 and 3 NTU. Sulphate concentration was the lowest at 431 mg/L in Fey and highest of 532 mg/L at Duro and Rifun Woro during the wet season. Chloride content within the wet season varied between 260 and 269 mg/L while that of the dry season varied between 124 and 130 mg/L. Highest and lowest concentrations of nitrate recorded during wet season was 0.42 and 0.23 mg/L for Kusogi and Fey respectively. The colour observed during the wet season ranged between 17 TCU and 19TCU while that of the dry season ranged between 10 and 13 TCU. Current status of the water in the study areas are fit as source of drinking water for the community, though plans should be put in place for mini treatment plants that can serve these communities to enhance good drinking water delivery..

“…More than 30% of groundwater supply in Lagos State taps water from the CPS to meet domestic, municipal, and industrial water demands (Akoteyon 2013). The aquifer is tapped for groundwater supply in Lagos through the establishment of the micro-and mini water works (Balogun et al 2012). Lateral variations exist in the CPS aquifer due to its lithology and water quality.…”

“…The approaches of water quality assessment and hydrochemical processes abound in the literature. For instance, the application of water quality indices (WQI) serves as a veritable scientific tool for assessing the suitability of water quality for various uses in an integrated manner (Balogun et al 2012). The WQIs also helps to reveal the effects of individual groundwater parameters on the overall water quality in a given location (Sarala and Uma Mageswari 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.

Water is one of the most important and most precious natural resources. It is essential in the life of all living organisms from the simplest plant and microorganism to the most complex living system; the human body. Water is combination of hydrogen and oxygen atoms, with a chemical formula H 2 O. It is known to be the most abundant compound (70%) covering the earth surface. It is significant due to its unique chemical and physical properties. But due to increase in human population, industrialization, use of fertilizer in agriculture and man-made activities, it is highly polluted with different harmful contaminants (Reda et al., 2016) Regular drinking water monitoring is essential for supplying people with a high quality and healthy water that meets requirements of legal regulations. According to Asonye et al., 2007), availability of safe and reliable source of water is an essential prerequisite for sustained development. However, human population will suffer from various water borne diseases with the continuous use of contaminated drinking water. The availability of good quality water is an indispensable factor for preventing diseases and improving quality of life. Natural water contains different types of impurities which are introduced into the aquatic system by different ways such as weathering of rocks and leaching of soils, dissolution of aerosol particles from the atmosphere and from several human activities, including mining, processing and the use of metal based materials (Ipinmoroti and Oshodi, 1993; Adeyeye 1994; Asaolu, 1997). The increased use of metal-based fertilizer in agricultural revolution of the government could result in continued rise in concentration of metal pollutions in fresh water reservoir due to the water runoffs. Also faecal pollution of drinking water causes water born disease which has led to the death of millions of people. (Adefemi and Awokunmi, 2010). Access to safe drinking water is key to sustainable development and essential to food production, quality health and poverty reduction. Safe drinking water is essential to life and a satisfactory safe supply must be made available to consumers. Water is thus becoming a crucial factor for development and the quality of life in many countries. In individual arid areas it has even become a survival factor. Therefore, water
