to know the water quality characteristics of tehran subterranean canals, from 20 feb. 1978 to 23 sept. 1978, samples were taken from 23 of them by simple random sampling without replacement, and were analyzed according to the 14th edition of standards method for the examination of water and waste water 1975. arithmetic average concentration of water analyses of 23 subterranean canals were drawn...

neurotoxicants present in water supply may affect human functions in terms of attention, response speed and perceptual motor speed. neurobehavioural performance can be influenced by gender, age and education levels. this study aims to assess the neurobehavioral performance of palm oil estate residents with private water supply in southern peninsular of malaysia.a total of 287 and 246 participan...

background and aims: the main cause of many problems in developing countries is related to the provision of safe drinking water. since the health of drinking water is important in the busy centers such as hospitals, clinics and health centers, this study was done to investigate the role of water coolers connected to the municipal system in microbial quality of drinking water in behbahan city. m...

the paper presents the case study of the current formation of a brazilian pit lake from an iron ore mining activity. the water used for the filling of the lake comes from rain, ground water and the complementary pumpage from a close river. at its final stage, which will be reached around year 2018, lake aguas claras will have a surface area of 0.67 km2 and the depth of 234 m, which will make it...

for better understanding of tehran ground water, samples were taken randomly from 340 out of 655 deep & semi deep wells in 1993, which dug by tehran water supply and sewage engineering company. 260 water specimens were examined chemically and physically and compared with the 1993 world health organization (who) and food and agriculture organization (fao) criteria and analyzed statistically. log...

drinking water has received considerable attention recently. however, misuse and mismanagement have resulted in a rapid and widespread decline in source-water quality and supply. water quality guidelines can be used to identify constituents of concern in water, to determine the levels to which the constituents of water must be treated for drinking purposes. membrane technology for the water cyc...

AWIXACT. A Geographic Information System (GIS)-based, lumpedparameter water quality model was developed to estimate the spat ia l and temporal n i trogenloadingpat terns for lower coastal p lain watersheds in eastern North Carol ina. The model uses a spatially distributed delivery ratio (OR) parameter to accountfor nitrogen retention or loss along a drainage network. Delivery rat ios are calcul...

The development of a surface water evaluation index is a critical factor in the assessment, restoration and protection of stream water quality. Quantifying water pollution in specific grade using dominant parameters is important, as this can explain the current state of water pollution with accuracy. As a result, an integrated multi-parameter water quality index has been developed. It is based ...
