Farmers in peri-urban areas use diluted wastewater for irrigation. Over time, heavy metals may accumulate in agricultural soils and food crops causing health problems when consumed. Physicochemical, heavy metals (cadmium, lead and chromium) and microbial analysis of water, soil and vegetables were conducted to ascertain the quality of water and vegetables using standard methods. The results of the study showed that the water quality indicators; dissolved oxygen, biochemical oxygen demand and water temperature were not within the recommended standards of Ghana’s Environmental Protection Agency. The presence of heavy metals in the water, soil and vegetables were in the order of; soil (1.47 ± 0.017 of cadmium, 0.0019 ± 0.00011 of chromium and 0.541 ± 0.017 of lead) > vegetable (1.472 ± 0.044 of cadmium, 0.0020 ± 0.00010 of chromium and 0.474 ± 0.021 of lead) > water (0.068 ± 0.009 of cadmium, 0.0047 ± 0.00037 of chromium and 0.110 ± 0.014 of lead). Cadmium, chromium and lead concentrations in soil, vegetables and water varied significantly. Cadmium and lead concentrations as well as coliform counts in water and vegetables exceeded Food and Agriculture Organization/ World Health Organization’s maximum permissible levels. Soil samples from the control site showed almost negligible concentrations of heavy metals (0.00017 mg/kg of cadmium, 0.00014 mg/kg of chromium and 0.0011 mg/kg of lead) whereas farm sites had heavy metals as a result of long-term wastewater irrigation. Cadmium and lead concentrations in the water and vegetables makes them toxic and microbial populations of faecal coliform in water and lettuce indicated faecal contamination. Therefore, the quality of vegetables produced using the Bibini river is low and unsafe for human consumption.

Water is one of the most important natural resources which play an essential role in human life. Most of the Nigerian institutions stored water in either plastic or overhead tanks for different purposes. However, there has been a growing concern over the safety of the stored water for human consumption following reported cases of microbial occurrence in water stored in tanks. This study aimed at investigating the water quality stored in plastic tanks in Umaru Musa Yar’adua University Katsina. Water samples were collected from plastic tanks and analyzed for some physico-chemical and heavy metals parameters. The result of physico-chemical parameters obtained shows that only dissolved oxygen, biological oxygen demand and chemical oxygen demand were observed above the maximum permissible limit for drinking recommended by WHO and NSDWQ with the mean value of 55.18 mg/l, 38.86 mg/l and 38.08 mg/l respectively. While the remaining parameters such as pH, electrical conductivity, total dissolved solids, turbidity, total suspended solid, alkalinity, sulphate, nitrate, phosphate, chloride and total hardness were found within the acceptable limit. However, analyzed result of heavy metals parameters revealed that all parameters were observed within desirable limit by WHO and NSDWQ for drinking water and suggested that the quality of water stored in plastic tanks was very good. It is concluded that, the quality of water stored in plastic tanks is suitable for human consumption. It is therefore recommended that, continuous monitoring of the water should be maintain so as to ascertain the safety of the water

Abstract Although flood hit the entire part of Chennai, Tamil nadu some three years ago, the quality of water is still found to be worse because of major inundation in these areas. The current inspection deals with the physico-chemical analysis of the ground water samples collected from ten locations in Neelangarai and Triplicane area in Chennai, Tamil Nadu and assessed using Heber Water Quality Index (HWQI) in the post tsunami circumstances. The factors examined were pH, fecal coliform, total dissolved solids (TDS), dissolved oxygen (DO), temperature biochemical oxygen demand (BOD) and turbidity. In addition to these parameters, pointers like electrical conductivity and salinity were also taken into consideration. The over all HWQI outcomes for all the trials in Neelangarai area were determined between 65.02 and 72.25 and Triplicane area was 66.64 - 70.71, which suggest that all the samples are medium to good in quality and could used for human consumption.

Potable water is becoming progressively scarce due to anthropogenic pollution and it has necessitated monitoring of water quality of rivers and dams as a subject of ongoing concern and research. This study was conducted to assess the quality of water collected from four different dams (Agba, Igbaja, Oloru and Omu-Aran) in Kwara State, Nigeria using standard procedures. Water and sediment samples were collected from three different spatial locations on the dams. The average values of most physicochemical parameters like pH, temperature, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Total Dissolved Solid (TDS), Total Hardness (TH), Alkalinity, some nutrients such as chloride (Cl-), sulphate (SO42-), phosphate (PO43-), nitrate (NO3-) and some heavy metals such as Cu, Zn have values that were within World Health Organisation (WHO) guidelines for drinking water for each of the dams while Cd and Fe concentrations were observed to be much higher than WHO guidelines for drinking water. This could be as a result of anthropogenic input. The dams’ sediments analyzed for heavy metals showed that Mn, Zn and Cd were high in the dams, which can be easily washed into the water body through leaching, thereby causing detrimental effect to the consumers.

Taking in consideration that drinking water is a vital element without which the normal existence of humans and other living things in our planet cannot be thought of, we are motivated to research the wells and springs used for drinking in the villages of Bajgora, Kovacica and Kaqandoll. The suspicion that the waters of this mountain massif contain heavy metals due to the presence of mineral ores also prompted us to investigate the degree of presence or not of heavy metals in these waters. To assess the water quality of these wells, in the monitoring network that includes these three villages, we have pinpointed five monitoring points, determining the organoleptic, physic-chemical, and microbiological and heavy metal parameters. During the research process, in order to evaluate the water quality as accurately as possible, classical and instrumental methods of chemical analysis were applied. We have compared the results of the analysis with the standard values of AI16 / 2012- Administrative Instruction of Kosovo that has to do with the quality of water for human consumption and that is in full compliance with EU Directive 98/83 EC. The obtained results denote the presence with heavy metals of Pb, Zn, Cd and Ni, in four of the five samples taken for research. Therefore, we have come to the conclusion that the presence of these metals results as a consequence of the geological composition and ore-rich underground layers of this mountain massif.

Present communication deals with a study of Physico-chemical parameters such as pH, Temperature, Total Suspended Solids, Turbidity, Dissolved Oxygen, Biochemical Oxygen Demand, Nitrate and Phosphate in water samples of Channarayapatna, Janivara, Anekere and Baghur water bodies in Channarayapatna taluka, Karnataka state of India. The water quality of the samples was compared with standard values given by World Health Organization (WHO) and United State Salinity Laboratory for drinking and irrigation purposes. Water Quality Index (WQI) was also calculated to know the overall quality of water samples. Water quality index (WQI) of Surface water body of various Sampling locations of Channarayapatna taluka, Karnataka ranged between 61.82 and 68.27 indicates the fair quality of water. The water quality index is calculated by indicator (100-point scale) shows that water is suitable for drinking purposes only after pretreatment like filtering, boiling, reverse osmosis and electro dialysis. WQI can play a big role in justifying the water pollution problems after encountered in different surface water bodies. Application of Water Quality Index (WQI) in this study has been found useful in assessing the overall quality of water and to get rid of judgment on quality of the surface water.Int J Appl Sci Biotechnol, Vol 4(4): 475-482

The aim of the study is to assess the quality of water from selected recreational fountains in Ciechocinek and Inowrocław health resorts. All analyzed water fountains are characterized by seasonal changes in their discharge. The exceedance of biochemical oxygen demand and chemical oxygen demand values found in the water samples may indicate water contamination with compounds of organic origin getting from the external environment to the basin of the fountain or too little recirculation of water. A significant improvement in water quality was noted in fountains in which water exchange occurred due to, for example, its failure. In addition, the water was characterized by a relatively high content of general hardness and conductivity. Reported exceedances of water quality parameters disqualify it for direct human consumption. It does not meet the requirements for drinking water. It is recommended to introduce supervision over the quality of water from fountains by the bodies of the State Sanitary Inspection in the form of water monitoring in order to eliminate from the water compounds that may have a negative impact on human health. It is recommended to regularly use pre-filtration, chlorination and sodium hypochlorite in water in fountains to eliminate physical impurities.
