“…In the view of [9], groundwater is believed to be comparatively much clean and free from pollution than surface water. This view is in agreement with the observations of [12] and [13] where it was revealed that exploitation of underground water for domestic purposes is prominent in developing countries because of the susceptibility of surface sources to pollutants and also as a result of its fair quality. It was also emphasized that groundwater is less open to pollutants and when even contaminated water is introduced to the surface of the earth, it undergoes natural treatment in the course of infiltration before it replenishes or added to the antecedent groundwater.…”

“…13 shows that the most widely varied parameter studied in the study area is coliform counts as the entire area have 9 regional patterns. Lagelu, Oyo West and Ona-Ara LGAs are grouped at the base of classification as strongly low region while 12 LGAs namely Orelope, Iseyin, Itesiwaju, Kajola, Shaki East, Egbeda, Shaki West, Ibarapa Central, Ibarapa East, Oriire, Irepo and Ibarapa North are at the peak of the classification, the strongly high region. The remaining LGAs are either moderately high, high, mildly high, low, moderately low or strongly low.…”

The knowledge of spatial pattern of groundwater quality is important to ensure a holistic approach to the management of the resource quality status in space and time. Thus a sample each of underground water was collected from each of the selected 5 rural communities in each of the selected 25 out of the 33 LGAs in Oyo State for the purpose of quality assessments. Eleven (11) parameters namely water temperature (°C), pH, electr ical conductivity (EC), Sodium (Na + ), SO 4 , Potassium (K + ), Nitrate (NO 3 ), Phosphate (PO 3 ), coli-form count, Oxidation Redox Potential (ORP) and Total Dissolved Solids (TDS) were subjected to standard laboratory analysis. The data was further subjected to analysis of variance and Duncan post-hoc test. ArcGIS version 10.1software was applied to generate maps to show the Duncan groupings of each of the quality parameters across the study area. Two (2) parameters namely pH and sulphate show homogenous distribution while the other nine (9) parameters are heterogeneous. Descriptive analysis showed that the groundwater in the study area is generally fit for human consumption. However, adequate attention needs to be given to temperature and potassium contents because they both slightly exceeded the Ogunbode and Ifabiyi; JGEESI, 11(1): 1-15, 2017; Article no.JGEESI.34634 2 standard required. The mapping affords spatial understanding of the distributional pattern of the parameters so that appropriate water quality management measure/s can be taken at a minimised cost to ensure appropriate levels of the parameter in the water to safeguard human health. Repeated investigation is required to determine the regularity or otherwise pattern of the water quality parameters. Original Research Article

Ground water is well described through some physical and chemical characteristics viz temperature, pH, turbidity, electric conductivity, total dissolved solid, total hardness, total alkalinity, nitrates, chlorides, fluorides and metal ions like calcium, magnesium, iron etc. Ground water is commonly used as drinking water for human worldwide, because it is quite economic, easy to use and less vulnerable to contamination than surface water. Nowadays, industrialization, urbanization, fast growth of civilization and increase in population have led to deterioration of the groundwater quality rapidly. Domestic and industrial discharge, landfills, improper drainage system, seepage through sewer lines, agricultural practices such as intense use of pesticides and fertilizers, uneven rainfall and mismanagement are some of major causes for its pollution. Therefore, it is necessary that the quality of ground water should be checked regularly for some physical and chemical parameters as their presence in water above the permissible limit has a serious effect on human health. Hence assessment of physicochemical characteristics of ground water is very important for human health studies and therefore an important research topic in recent years. In the present work, physicochemical characteristics associated with ground water are reviewed along with their health effects.

“…They studied the degree of fluoride contamination and identification of hydrogeochemical process in mobilising the fluoride contamination. Thangavelu (2013) has mapped the quality of groundwater using GIS in Coimbatore, India. GIS provides sophisticated map-generation capabilities, useful in communicating results of data analysis (Burrough and McDonnell, 1998).…”

Fluoride contamination of groundwater is an emerging problem all over the world. Occurrence of fluoride in groundwater has drawn worldwide care due to its significant influence on human physiology. Fluoride is a vital element, which is good for the teeth enamel and helps to avoid dental and skeletal caries. In excessive doses, it leads to fluorosis. In India most of the people in rural areas are dependent on groundwater for drinking purposes and have a possible chance of developing fluorosis. In the present study, assessment of fluoride hazard of groundwater quality was carried out in Palghat District from January and December 2012. Assessed 64 groundwater sample locations were interpolated using inverse distance weighted (IDW) method in ArcGIS 9.3. The results shows that fluoride contamination in groundwater is high in month of January (>0.87 mg/l) compared to December (>0.69 mg/l). Among the 12 blocks of Palghat District, Kollengode block is highly affected by fluoride contamination in the month of January and Chittur block in December. Groundwater quality of Kollengode and Chittur blocks is highly affected and it is unhealthy for drinking with prior treatment.
