Geneva, 1985 (ISO 7888:1985). volume 5, Article number: 1 (2016) J Chem Soc Nigeria 36(1):95–101, Ezeribe AL et al (2012) Physico-chemical properties of well water samples from some villages in Nigeria with cases of stained and mottle teeth. Therefore, this study is conducted at Wondo Genet Campus to check drinking water quality and to suggest appropriate water treated mechanism. 0000031259 00000 n 0000005698 00000 n 0000345702 00000 n Electrical resistivity (also called specific electrical resistance or volume resistivity) and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts electric current.A low resistivity indicates a material that readily allows electric current. Fresh water is already a limiting resource in many parts of the world. 0000355435 00000 n Deterioration of drinking water quality arises from introduction of chemical compounds into the water supply system through leaks and cross connection (Napacho and Manyele 2010). Part of The study area is categorized under Dega (cold) agro-ecological zone at the upper part and Woina Dega (temperate) agro-ecological zone at the lower part of the area. 0000001260 00000 n In most of the countries, majority of water supply bears less than 20 mg/l, while in some countries the sodium quantity in water exceeded from 250 mg/l (WHO 1984). The current investigation ranges were 6.52–6.83 which are in the range of WHO standards. The samples were analyzed for intended water quality parameters following internationally recognized and well established analytical techniques. Nitric acid was used to preserve samples for metals analysis. The mean total dissolved solids concentration was found to be 118.19 mg/l, and EC value in Wondo Genet Campus was 192.14 μS/cm. Terms and Conditions, Both authors read and approved the final manuscript. Instead of this study small dam indicates the starting point of Wondo Genet campus drinking water sources rather than large dams constructed for other purpose. According to WHO standards, EC value should not exceeded 400 μS/cm. Drinking water in the South East mainly comes from rainwater. 0000004296 00000 n x�b```b``g`c`��� ̀ �@1v�� This is the important parameter for the use of water. 0000003906 00000 n Conductivity is a measure of the ability of water to pass an electrical current. According to WHO standards, concentration of sodium in drinking water is 200 mg/1. are developed for individual parameters to protect the environment According to WHO (2011) risk associated in Wondo Genet campus drinking water is low risk (1–10 count/100 ml). This was done by dipping the thermometer into the sample and recording the stable reading. The current investigation indicated that EC value was 179.3–20 μS/cm with an average value of 192.14 μS/cm. The results exhibit that concentration of sulfate in Wondo Genet campus was lower than the standard limit and it may not be harmful for human health. In addition, most sources are found near gullies where open field defecation is common and flood-washed wastes affect the quality of water (Messeret 2012). Similar value was reported by Soylak et al. In the study areas, the chloride value ranges from 3–4.4 mg/l in Wondo Genet Campus, and the mean value of this drinking water was 3.7 mg/l. The conductivity of this Solution at 25 OC, ~25, is 1 290 mS/m. Drinking water quality assessment and its effects on residents health in Wondo genet campus, Ethiopia. %PDF-1.4 %���� The mean values of total coliform bacteria in drinking water. All drinking water samples collected from Wondo Genet Campus were analyzed for total coliform bacteria and ranged from 1 to 4/100 ml with an average value of 0.78 colony/100 ml. ...
