Domestic Purpose

Water wells are usually dug by artisans who lack professional skills. Such wells are used at various homes in Gwagwalada Area Council of Abuja for domestic purpose, on the assumption that underground water is safe. Thus, the suitability of such well water was assessed. The objectives were to assess their properties and compare with regulatory standard for domestic purpose. Thirty (30) water samples were purposely collected from six wards (Dobi, Ibwa, Paikon-Kore, Tungan Maje, Zuba and Ikwa). Five water samples were randomly collected from each ward for laboratory analysis. Laboratory results were statistically analyzed using range, mean, correlation and multiple determination coefficients. Suitability of water properties for domestic purposes was determined by comparing range and mean values with NSDWQ and WHO standard for domestic uses. Result showed that the concentrations of water properties ranges as follows: temperature (26.59-30.73oC), pH (7.17-8.23), electrical conductivity EC (222-354 μs/cm3), TDS (12.14-21.54mg/l), Turbidity (0.29-0.93NTU) hardness (13.58-39.72mg/l), chloride Cl-(4.29-8.93mg/l), Fe (0.54-0.71mg/l) and Cu (0.02-0.06mg/l).Water samples generally had low electrical conductivity (222-354 μs/cm3), and mineral nutrients but elevated concentration of some heavy metals. The twenty- three water quality parameters tested could explain 96% of the overall water quality leaving only 4% unexplained. All the samples fell short of regulatory standard in terms of EC, Fe and Cu while well water from Ikwa fell short of many heavy metals for domestic purpose. It was concluded that well water in Gwagwalada Area Council are not potable. Thus, treatment before direct consumption and precautionary use of well water were recommended for the residents.

The Impact

This study aims to investigate the quality and vulnerability of surface water (Aries River catchment) in order to identify the impact of past mining activities. For this purpose, the pollution and water quality indices, Piper and Durov plots, as well vulnerability modeling maps were used. The obtained results indicate that the water samples were contaminated with As, Fe, Mn, Pb and have relatively high concentrations of SO42−, HCO3−, TDS, Ca, K, Mg and high values for the electrical conductivity. Possible sources of the high content of chemicals could be the natural processes or the inputs of the mine drainage. Generally, according to the pollution indices, which were correlated to high concentrations of heavy metals, especially with Pb, Fe and Mn, the water samples were characterized by heavy metals pollution. The water quality index classified the studied water samples into five different classes of quality, namely: unsuitable for drinking, poor, medium, good and excellent quality. Similarly, medium, high and very high vulnerability classes were observed. The Durov and Piper plots classified the waters into Mg-HCO3− and Ca-Cl− types. The past and present mining activities clearly change the water chemistry and alter the quality of the Aries River, with the water requiring specific treatments before use.

The water quality of the transboundary Pyanj River in the formation zone and along the riverbed before merging with another tributary of the transboundary Amu Darya River-the Vakhsh River was studied. The water quality on the upstream river corresponds to the very soft class (> 1.5 mmol/dm3) and in the middle and the downstream to the soft class (1.5-3.0 mmol/dm3). At the upper, middle and lower reaches of the Pyanj river the concentration of alkaline earth exceeds alkali metals (Ca2+ + Mg2+> Na+ + K+) at HCO3- > SO42- + Cl- and according to the Handa classification they are characterized by temporary rigidity. To assess the criterion of applicability of the Pyanj river water for irrigation the coefficient of sodium adsorption (SAC) was calculated for water samples from the upstream (Khorog), middle (Darvaz) and the downstream (Lower Pyanj) of the Pyanj river that were equal to 0.88; 1.07; 1.71, respectively. The SAC values for all water samples (from the upper, middle and lower reaches) of the Pyanj river indicate their good qualities for irrigation of agricultural land. The concentration of heavy metals in the Pyanj river is significantly lower than the maximum permissible concentration (MPC).

Water Quality Indices

The present study was conducted to evaluate the quality of drinking water in randomly selected schools in Erbil city, Kurdistan Region, Iraq. The water quality indices such as the Heavy metal Pollution Index (HPI) and Heavy metal Evaluation Index (HEI) were applied to characterize water quality. Eighteen schools were incorporated and sampled for their water storage tanks available to students. Water samples and sediment samples from tanks floor were analyzed by Inductively Coupled Plasma Optical Emission Spectrometer for the determination of twenty-two metal elements. In drinking water samples, all detected metals did not exceed the permissible limits of the World Health Organization. The results of this study showed that the average values of HPI and HEI for As, Cd, Cr, Cu, Fe, Pb, Mn, Ni, and Zn were 54.442 and 0.221, respectively. According to data of the water quality indices, the schools drinking water quality are good and suitable for drinking in terms of heavy metals. However, sediments samples contained high concentrations of all elements including the toxic heavy metals (As, Cd, Cr, and Pb). Re-suspension of sediments into water column after refilling storage tanks can pose a serious threat to students drinking water from such vessels. It is therefore recommended that proper storage tanks are provided to the schools accompanied by continuous sanitation and hygiene practice to mitigate the corrosion of tanks to avoid health risks of toxic metal

This study was conducted to know the status of physicochemical water quality parameter and heavy metal concentration in the water of Buriganga river, adjoining to Dhaka city. Water samples were collected from five different points of Buriganga river and were analyzed to determine pH, electrical conductivity (EC), total dissolved solids (TDS), dissolved oxygen (DO), biological oxygen demand (BOD), chromium (Cr), lead (Pb), cadmium (Cd), copper (Cu) and manganese (Mn) content. Most of the measured water quality parameters and concentration of heavy metals were exceeded the standard level set by ECR and ADB. Among heavy metals concentration, level of chromium and cadmium were 4-5 times higher than the standard drinking level, these results indicate that surrounding industrial wastewater discharging from textile and tannery industries, which pollute the Buriganga river water. During the observation, at Hazaribagh station BOD level was found 32 times higher than drinking water standard level and 6 times higher than standard irrigation level, indicating Buriganga river water is extremely polluted by microorganism and is not suitable for household and irrigational use. Similarly, DO level at Buriganga river water was 5 times lower than the standard level, which indicates that Buriganga river water is extremely polluted and is unsuitable for aquatic life which are dependent on DO for their sustain. In the present study, the measured level of EC, chromium, cadmium and copper were found higher level as compare to the previous studies.J. Environ. Sci. & Natural Resources, 9(2): 97-104 2016

Abstract Background An increase in the urban population and the rising demand for food and other essentials perpetuate a rise in the amount of waste being generated daily by each household. In low-income countries, this waste is eventually thrown into open dump sites. It can cause severe impacts on human health and the surrounding environment. This study was aimed at assessing the effect of a solid waste dump site of Teppi town on surrounding soil and river water quality. Methods A total of three surface water, one leachate water samples, and four soil samples were collected and were analyzed. Six heavy metals for surface water and leachate samples and four heavy metals for soil samples were measured by flame atomic absorption spectroscopy. Additionally, physical and chemical parameters were analyzed using standard methods. The soil and water data were analyzed statistically using Origin pro version 8.0 computer software packages. Analysis of variance (ANOVA) was used to assess whether the mean values of heavy metals and physicochemical parameters in soil and water samples varied significantly between distances and location from the dump site, possibilities less than 0.05 (p< 0.05) was considered statistically significant. Results pH of soil was slightly basic (pH 8±0.1 up to 8.7±0.21. Similarly, EC was lower in 60 meters (1800±0.5μs/cm) and higher in the other sample sites (3490±0.66-4920±1.04μs/cm). The concentration of heavy metals such as cadmium (0.53±0.01-2.26±0.02 mg/kg), zinc (623.93±0.29-859.41±0.02mg/kg), lead (3.26±0.25-57.560.26mg/kg), and copper (204.06±0.06 337.11±0.01mg/kg) in the sample soils has been found to be higher than Ethiopian EPA and USEPA guideline values. Lead, cadmium, manganese, nickel, copper, and zinc in the leachate water and nickel and manganese in nearby river water, total dissolved solid, BOD5, chemical oxygen demand, and turbidity for both leachate and stream water samples were found to be higher than the Ethiopian EPA and WHO standard guideline values. Conclusions The finding suggested that solid waste open dump site adversely affects soil and water quality in the study area and probable source of human health risks via the food chain. The soil in the area requires Phytoremediation technologies. In addition, sanitary landfill is recommended.
