Potable water is essential for human survival but contaminations through human activities have jeo pardized it. This research will create awareness on the condition of hand dug well water used and reduce transmission of diseases in the study areas. The study deals with the determination of physic-chemical parameters and Mineral composition of water samples collected in the month of September, 2019 from hand dug well from selected local government areas in Oyo State Nigeria, (Ibadan North-East, Ibarapa Central, Afijio, Ogbomoso South and Iseyin local government). The parameters examined were Temperature (ToC), Potential Hydrogen (pH), Conductivity (µ/S-1/cm), Total Dissolved Solid (TDS ppm), Salinity (ppm), Dissolved Oxygen (DO mg/L),Potassium (K+), Calcium (Ca2+), Magnesium (Mg2+), Zinc (Zn2+) and Chloride (Cl-). Standard analytical methods were used. The analytical results of the study revealed that Temperatures are within 27 and 28oC, the pH of the samples ranges from 4.7-6.8, Conductivity falls between 785-1671 µ/S-1/cm. The TDS ranges from 550-1346 ppm, Salinity from 384-956 ppm while DO had the values ranges of 6.03-11.44 mg/l. Potassium (K+) (1.92-6.22 mg/l), Calcium (Ca2+) (14.74-18.52 mg/l), Magnesium (Mg2+) (6.34-7.81 mg/l), Zinc (Zn2+) (0.39-0.47mg/l) and Chloride (Cl-) (26.19-28.70 mg/l). It was noted that, Conductivity, salinity and DO were high compared to WHO and NSDWQ permissible standard limits. This indicated that pollution from dumpsites and erosion has great impact on the water. The mineral compositions of the water samples are within the permissible limit recommended by WHO. It is advisable that proper drainage and sewer systems should be constructed in all areas to ensure proper disposal of hazardous liquid waste, thereby preventing seepage into groundwater and surface water.

This study aims to determine the iron content of water wells in Dulalowo and Heledulaa, Gorontalo City. Ten well water samples were taken randomly from five different wells in each district. Water samples at each well consist of top, middle, and bottom water. Determination of iron level using Atomic Absorption Spectrophotometer (AAS) at a wavelength of 248.33 nm. The results showed that the iron concentration of well water in Dulalowo was 0.030 (D1), 0.265 (D2), 0.224 (D3), 0.158 (D4), 0.149 ppm (D5). Meanwhile, iron levels in Heledulaa were 0.100 (H1), 0.039 (H2), 0.159 (H3), 0.198 (H4), and 0.235 ppm (H5). These results prove that the Fe content in the well water in the two districts is still fulfil the drinking water standard which is a maximum of 0.3 mg/L iron.

<p>Chloride is an anion that dissolves easily in water samples and it is the main inorganic anion founded in water samples. Excess of chloride ions in drinking water can damage the kidneys. The aims of this study is to determine chloride levels in well and PDAM water samples in Ngelom Village. Determination of chloride levels in water samples using the Mohr argentometric titration method. The samples used was well water and PDAM water, each was taken from 20 locations in Ngelom Village. The samples were mixed with K<sub>2</sub>CrO<sub>4</sub> indicator and then were titrated using the silver nitrate standard solution until the end point of the titration was marked with a brick red color. The results of the analysis of chloride levels in well water of 92 to 491 mg/L and in PDAM of 57 to 230 mg/L. Based on these results, it can be concluded that chloride levels in both well water and PDAM water samples were below maximum threshold which appointed in Permenkes RI No. 416/Menkes/Per/IX/1990 (≤600 mg/L).</p>

Thirty six dug well water samples from different houses along three transects and four Buriganga river water samples from four different Ghats (boat terminals) of the Old Dhaka of Bangladesh were collected during dry and wet periods for water quality assessment. The depth of these dug wells varies from 3.4 to 16 m with an average depth of 10 m with diurnal variations. The hydrochemical classification shows that the dug well and Buriganga river water samples are Ca-HC03 type. More than 50% dug well water samples were contaminated as concentration levels of Ca, K and Fe in both periods were high whereas over 25% Buriganga river water samples were tainted as concentration levels of Ca, Mg, Fe and Mn in dry season exceeded the drinking water quality standard limits of World Health Organization (WHO), Department of Environment (DOE) and United States Environmental Protection Agency (USEPA). If the dug well water is protected from contamination, the shallow groundwater in this part of Dhaka city should be an alternative perennial source of water especially during the dry season when water scarcity looms large Asiat.
