High concentration of contaminants in drinking water can affect human health. This study assessed quality of groundwater at industrial and residential areas of Sango Ota, Ogun State. Water samples were collected in triplicates from 8 wells at industrial and residential areas and analyzed for its physicochemical properties. The pH, electrical conductivity, total dissolved solid (TDS), nitrate, sulphate, total suspended solid (TSS), total hardness (TH), iron, zinc, copper, lead, nickel, chromium and cadmium concentrations in the water samples were determined following American Public Health Association (APHA) procedure. Results showed that pH of 50 % of the wells were lower than minimum limit of 6.5 recommended by WHO. Sulphate, TH and iron in the water were significantly (p < 0.05) higher at residential area than industrial area. Electrical conductivity exhibited significant (p < 0.01) correlation with TDS (r = 0.701**) and NO32- (r = 0.922**) at residential area. At the industrial area however, concentration of salts in water samples was highly associated with SO42- (r = 0.864**) and Cd (r = 0.587**). Across locations of groundwater, iron and lead were above allowable WHO limits in drinking water. Cadmium was also above drinking limit at location T4 of the residential area. Consumers of groundwater in the study area are prone to health related challenges of heavy metal toxicity.

Quality of soil and water are determined by measuring the concentration of their parameters and comparing them with standards. In the present study, soil samples (top, sub and inner) from three zones, zone 1 (industrial area), zone 2 (10km from industrial area) and zone 3 (agricultural land/fields) of Puliyanthangal village, and the bore well, well and pond water samples of Kathiyavadi village were analysed from January 2019 to December 2019. Soil texture was sandy loam in all the zones. The pooled values for pH, electrical conductivity (dS/m), organic carbon (%), available nitrogen, phosphorous, potassium, iron, manganese, zinc and copper (mg/Kg) tested in zone 1, 2 and 3 were 7.9, 6.8 and 6.8; 0.3, 0.3 and 0.1; 0.09, 0.5 and 0.5; 11.7, 96.0 and 137.8; 4.5, 4.5 and 4.2; 88.3, 111.3 and 206.7; 3.6, 3.4 and 3.7; 2.1, 1.7 and 2.3; 0.4, 0.3 and 0.2; and 0.7, 0.5 and 0.7, respectively. The bore well and well water samples were clear and colourless without odour, whereas the pond water was slightly yellowish in appearance and colour, and without odour in all the three zones. The physicochemical parameters viz., water temperature, electrical conductivity, turbidity, total dissolved solids, pH, total alkalinity and total hardness for bore well, well and pond water were 27.9, 22.8 and 33.0°C; 975, 1532 and 737μS/cm; 0, 1 and 11NTU; 683, 1072 and 516mg/L; 7.4, 7.8 and 7.3; 276, 344 and 248mg/L; and 190, 732 and 272mg/L, respectively. Calcium, magnesium, free ammonia, nitrate, nitrite, chloride, fluoride, sulphate and phosphate represented the nutrient parameters and their respective values (mg/L) were 41, 174 and 58; 21, 71 and 30; 0, 0 and 1.1; 24, 29 and 22; 0, 0 and 0.8; 100, 184 and 60; 0.4, 0.4 and 0.4; 77, 120 and 49; 0, 0 and 0.8. The values of metal parameters reported nil except for iron (0.2mg/L) in pond water. The study inferred that the waning nature of soil and water might be due to location of industrial units.

&lt;p&gt;The Chindwin River, a major tributary of the Ayeyarwady River in Myanmar, is approximately 850 km long with a watershed area of 115,300 km&lt;sup&gt;2&lt;/sup&gt;. The Chindwin River is essential for local livelihoods, drinking water, ecosystems, navigation, agriculture, and industries such as logging and mining. Over the past two decades, Myanmar&amp;#8217;s rapid economic development has resulted in drastic changes to socio-economic and ecological conditions in the basin. Water users in the basin reported that there is a rapid extension of gold and jade mining and they observed a noticeable decline in water quality along with increased sedimentation and turbidity. So far, however, Myanmar has not undertaken a comprehensive scientific study in the Chindwin River Basin to assess water quality and sources of water pollution and to effectively address issues of river basin degradation and concerns for public health and safety. This study aims to assess the status of water quality in the Chindwin River and the potential impact of mining activities on the water quality and loading through monitoring program and modeling approach. 17 locations in the upper, middle and lower parts of the Chindwin River Basin were selected for water quality monitoring. These sites are located near Homalin, Kalewa, Kani and Monywa townships where human activities and interventions could affect water quality. Water quality sampling and testing in the Chindwin River was conducted two times per year: in the dry season (May-June) and in the wet season (September-October) during 2015-2017. We monitored 21 parameters including heavy metals such as Lead (Pb), Mercury (Hg), Copper (Cu) and Iron (Fe). The observed values of Mercury in Uru River in the upper Chindwin River Basin which located nearby gold mining sites shown higher than the WHO drinking standard. This area also has high values of turbidity and Total Suspended Solid. The SHETRAN hydrological model, PHREEQC geochemical model and LOADEST model were used to quantify the heavy metal loads in the Uru River. Results from scenario analysis indicate an increase in Arsenic and Mercury load under increment of concentration due to expansions in mining areas. In both baseline and future climate conditions, the Uru downstream area shows the highest load effluent in both Arsenic and Mercury. These heavy metal loads will intensify the declining water quality condition in Chindwin River and can impact negatively on human health who use water for drinking. Therefore, we recommend that water quality monitoring should continue to provide scientific-evidence for decision-makers to manage water quality and mining activities properly.&amp;#160; Water treatment systems for drinking water are required to remove turbidity, Total Suspended Solid, and Mercury from raw water sources. Raising awareness of relevant stakeholders (local people, farmers, private sectors, etc.) is necessary as many people living in the Chindwin River Basin are using water directly from the river and other waterways without proper water treatment.&lt;/p&gt;

Water as excellent natural resource is meant to be of good quality to prevent the outbreak of water-borne diseases. The physical, chemical and biological qualities of water constitute groundwater quality. Water of poor physicochemical quality may have adverse effects on human health and the economy. The physicochemical evaluation of fifteen borehole waters in mile 50 Abakaliki was carried out during the rainy and dry seasons to determine their suitability for drinking using standard analytical methods. During the rainy season, the temperature was 28-30°C; pH, 6.63-8.51; dissolved solids, 1.04-17.01 mg/l; total suspended solids, 0.09-0.98 mg/l; total solids, 1.14-17.99 mg/l; electrical conductivity, 107-328 us/cm; turbidity, 1.27NTU-2.60 NTU total alkalinity, 27.68-82.23 mg/l; total hardness, 70.20-150.84 mg/l; total chloride, 67.30-124.14 mg/l; calcium hardness, 24.50-53.58 mg/l; magnesium hardness, 39.40-97.26 mg/l; sulphate, 30.03-61.88 mg/l; phosphate, 0.25-6.71 mg/l; potassium, 0.00-8.04 mg/l; nitrate, 1.16-8.03 mg/l; iron, 0.00-0.26 mg/l; lead, 0.00-0.05 mg/l; cadmium, 0.00-0.04 mg/l; copper, 0.00-0.23mg/l; chromium, 0.00-0.05 mg/l and zinc, 0.07-2.15 mg/l. During the dry season the temperature was 27-29°C; pH, 6.40-7.75; electrical conductivity, 24-149 us/cm; dissolved solids, 0.10-2.03 mg/l; total suspended solids, 0.02-0.29 mg/l; total solids, 0.13-2.64 mg/l; turbidity, 0.61NTU-1.90 total alkalinity, 19.96-55.97 mg/l; total hardness, 49.61-82.35 mg/l; total chloride, 26.31-80.72 mg/l; calcium hardness, 5.63-29.30 mg/l; magnesium hardness, 30.54-67.30 mg/l; sulphate, 13.88-39.18 mg/l; phosphate, 0.07-3.18 mg/l; potassium, 0.00-4.73 mg/l; nitrate, 0.44-4.95 mg/l; iron, 0.00-0.16 mg/l; lead, 0.00-0.02 mg/l; cadmium, 0.00-0.02 mg/l ; copper, 0.00-0.15 mg/l; chromium, 0.00-0.03 mg/l and zinc, 0.02-0.64 mg/l during the dry season. From the average 7% of cadmium and 33% of lead in the water samples were above the NIS required limits of 0.003 and 0.01mg/l respectively. Generally, the water from the borehole was of poor physicochemical quality and must be treated adequately before being used by humans.

Water, source of life, is also a source of disease when it is polluted. The aim of this study is to analyze the physicochemical quality and the bacteriological quality of the wells, boreholes and tank for drinking water in the Commune of Allada. The methodology is based on the collection of data, data processing and analysis carried out at the Laboratory for Quality Control of Water and Food (LCQEA) of the Ministry of Health. From the water sampling carried out at three (03) traditional wells, two (02) boreholes, two (02) tanks and water of river (02), bacteriological and physicochemical analysis were performed. The results showed that pH is higher at the tank than other water sources. Well 3 (P3) has a very high electrical conductivity (EC) which was 384.95 μS / cm and 192.47 mg / L for total dissolved solids (TDS). The tank 2 exhibited high value in pH 9.14; 71.72 (μS / cm) for the electrical conductivity (CE) and 35.86 mg / L, in total dissolved solids (TDS). Well 2 (P2) has a high turbidity of 4.53 (NTU) at all analyzed water points. The concentration of iron, copper nickel and cobalt remains low(less than 0.4 mg / L).Wells 2 and tank 1 are concentrated in lead, respectively 20.75mg / L and 13.71mg / L. Tank 1 and 2 have a high concentration of cadmium compared to other water points. The presence of Escherichia coli with a high concentration at home SONEB (39 CFU) and at well 2 (7.10 2 ) was found. In view of these results some recommendations were made.

Water is very important to the existence of humans though could also serve as vehicle for pathogenic organisms and dangerous organic and inorganic matters. The physicochemical and microbial analyses of selected borehole water samples in Awka residential areas were conducted with the aim of ascertaining suitability or otherwise for human consumption. The total hardness, pH, alkalinity, some common elements and presence of toxic metals were determined by standard methods of American Public Health Association. The presence of microorganisms in the water samples was also determined. Results of the physicochemical analysis of the borehole water samples showed a mean pH value of 5.52 below the WHO standard of 6.5 - 8.5 and mean total hardness of 150 ppm greater than the WHO standard of 70 ppm. The microelements such as manganese, zinc, lead, selenium, nickel and cadmium were found to be below detectable levels in the water samples. Five bacteria species were isolated and identified in the water samples as Staphylococcus epidermidis, Pseudomonas aeruginosa, Enterobacter aerogenes, Escherichia coli and Klebsiella pneumoniae. The physicochemical properties and the bacteria load of most of the water samples indicate that they were unfit for human consumption as the samples were outside WHO reference standard for potable water suggesting a need for increased awareness for improved sanitation and hygiene practices in the state.

Objective: We assessed the degree of risk to the health of the rural population of different ages with constant peroral intake of nitrates with drinking water. Materials and methods: The study was conducted within the rural residential areas of Zhytomyr region and it is a part of the research "Ecological and social assessment of the state of rural residential areas in the context of sustainable development." Drinking water samples were taken from public and private sources of decentralized water supply: wells, bore-wells and natural sources. A total 549 water samples were taken. In the study, we used general scientific methods: analytical, field, laboratory and statistical ones. Results: Among the studied areas, the largest excess of the average content of nitrates was recorded in drinking water of rural settlements of Berdychiv district. The risk assessment showed that the children aged 0-10 years were the most sensitive population to nitrates, and the women were more vulnerable to nitrates than the men among the adult population. The significant correlations between an excess of nitrate content in drinking water and cancer among adults and children in Berdychiv district have been proven. Conclusions: It has been proven that with a constant oral intake of nitrates with drinking water, harmful effects on the health of the rural population are observed, which, according to their sensitivity to their action, were distributed as follows: children 0-10 years old> adult women> adult men> adolescents.Taking into account the results obtained, it is necessary to monitor constantly the quality of drinking water sources of decentralized water supply in rural areas and to inform the rural population about water quality and the impact of its impurities on human health.
