Fuzzy Water Quality Index (FWQI) was applied in order to assess the degree of drinking water resources in Yazd province, Iran. Thisstudy has also offered the creation of a new fuzzy water quality index (FWQI) to evaluate this tool’s applicability. 12 chemicalparameters including toxic and non-toxic heavy metals measured in 71 groundwater samples collected from drinking water resourcesin rural a...

Introduction In a recent study of public-supply-well water quality in the United States, nearly two-thirds of all samples from 932 public wells tapping 30 regionally extensive aquifers contained detectable amounts of drinking-water contaminants that originated entirely or primarily from manmade sources. Twenty-two percent of the samples contained at least one contaminant (manmade or naturally o...

Arsenic pollution in groundwater caused serious environment and health problem world widely. Few are reported for the occurrence and mechanisms of arsenic pollution in deep aquifers, though it is well documented by numerous study for arsenic enrichment in shallow groundwater. In this study, arsenic pollution was found in deep wells for drinking purpose. A total of 112 drinking groundwater sampl...

fifty-four drinking groundwater samples were collected in april 2010 from some districts of the dakahlyia governorate, egypt. the water samples were analyzed by atomic absorption spectrophotometer for iron, manganese, lead, nickel, chromium, zinc, copper, cobalt and cadmium concentrations. all samples but two were found suitable for drinking; from the water sample from aga district showed sligh...

BACKGROUND Nitrite (NO2-) and nitrate (NO3-) contaminations of groundwater are considered as one of the major health challenges in recent decades. This study aimed to evaluate the nitrite and nitrate concentrations in the drinking groundwater of Shiraz, South-central Iran by statistical models. METHODS From 43 active wells of Shiraz drinking water supplies, 344 samples were collected in the h...

Groundwater quality regarding major anions and cations in the Birjand Plain located in the largest desert in Eastern Iran was monitored in this study. Fifteen boreholes were considered as sampling stations and the parameters pH, TDS, EC and major anions and cations were measured in groundwater samples. The dominant groundwater types can be introduced as sodium-chloride and magnesium-sulphate. T...

Fluoride is one of the parameters which is non-degradable and naturally occurring inorganic anion found in many natural streams, lakes, and groundwater. Serious problems are faced in several parts of India due to the high consumption of fluoride through drinking water. These may cause dental and skeletal fluorosis to humans. This study aims to examine the level of fluoride in both Bharalu river...
