In discussing the water quality evaluation for use in different purposes, the author will briefly examine some of the major important water quality standards. These standards serve as a basis for appraisal of the results of chemical water analysis in terms of suitability of the water for various intended uses. According to total dissolved salts (TDS),  major  ions as cations ( Ca2+, Mg2+, Na+, K+), anions (CO₃2⁻, HCO₃⁻  ,SO₄2⁻, Cl⁻), with some heavy metals such as Al3+, B3+ , Cd2+, Co2+, Cr3+, Cu2+, Fe3+, Mn2+,  Mo2+, Ni2+,  Pb2+, Sr2+, V2+   and Zn2+  The results  indicate  that  the samples of Nubian sandstone aquifer is suitable for drinking of human and livestock , suitable for laundry purposes and for irrigation. While the samples of Fractured dolomite limestone aquifer are unsuitable for drinking and irrigation.

Two constructed wetlands were evaluated regarding their performance in treating different wastewaters under the tropical conditions of Thailand. The first one was for treating the domestic sewage from a governmental institute, whereas the latter was used to improve the quality of the effluent from a central aerated lagoon, for which the influent had been already pretreated by about 100 factories in an industrial estate. The hydraulic loading rate and the hydraulic retention time were 0.015 m3/m2.d and 28 days and 0.3 m3/m2.d and 3 days for the two wetland systems, respectively. The physical and chemical water quality and the occurrences of protozoa and metazoa were monitored for three seasons, each of which had samples taken twice a week for two months. The temperature was quite constant throughout the whole year, ie., 26 to 31°C and 25 to 34°C for the two wetlands, respectively. The water quality of the wetland effluents was rather good; the BOD and TKN were only 4.5 and 3.3 mg/l and 2.7 and 6.8 mg/l for the two cases. A relationship between the filtered BOD and the zoological characteristics was established. As a result, a simple glance at the occurrence of certain metazoa and protozoa can rapidly but approximately predict the water quality of the system.

AbstractThe location and development of cities has been influenced basically by various environmental factors. However, the relationship is bilateral, because not only the environment can affect the city, but the city can affect the environment in different ways, depending on recovery. This is especially true in the case of large cities such as Budapest where the different geological, geomorphological, hydrological, soil and bio-geographical conditions can be changed in very small areas, which implies that land use can be also modified as well. The aim of our study was to determine the chemical water quality of three small streams in Budapest which have same water flow and compare the field and the laboratory test results. Between many natural characteristics of these streams similarity is evident, however, several differences were found between the watersheds in terms of human land use. Statistical data analysis was performed as well, which was the aim to explore the relationship between the parameters. Overall, according to our study it can be concluded, the small streams have similar water chemical properties, but some parameters need special attention in the future, because the investigated small streams can be categorized into polluted and sometimes heavily polluted category.

Water is one of the renewable resources essential for sustaining all forms of life and quality of drinking water is very fundamental for human health. Human activities such as mining act as sources of water contamination which consequently lead to ecological, environmental and health problems. To the best of our knowledge, no study has been conducted around the Thundulu Phosphate Mine to establish the quality of drinking water. In this regard, this study was carried out to evaluate the physico-chemical water quality parameters of areas surrounding the Thundulu Phosphate Mine in Phalombe District. Groundwater samples from the villages surrounding the Phosphate Mine were collected both during the wet and dry seasons for analysis of physico-chemical water quality parameters (pH, electrical conductivity, turbidity, nitrate, chloride, sulphate, fluoride, iron, calcium and magnesium). The study also investigated microbiological water characteristics mainly Escherichia coli and faecal coliforms. Results showed that pH, electrical conductivity, turbidity, nitrate, chloride, sulphate, phosphate, calcium and magnesium complied with the national and international standards set by Malawi Bureau of Standards (MBS) and World Health Organization (WHO). As regards to microbiological characteristics, it was revealed that water from three sources (B2, B3 and B4) was contaminated with Escherichia coli and faecal coliforms.
