An Assessment on the Safety of Drinking Water Resources in Yasouj, Iran

Abstract

The health of drinking water is an important criterion for developed countries and around half of the world’s population is deprived of sanitary and safe drinking water. By identifying the time of pollution occurrence and the places that are most sensitive to pollution the management of the quality of drinking water can be planned. Since the landfill for Yasouj, a city in Iran, was located in a higher place than the drinking water wells, which were drilled in a karst aquifer, the safety of the drinking water resources (including eight wells) of Yasouj were investigated in the present study. For this purpose, different parameters, comprising the concentration of eight heavy metals and eight ions, alkalinity, total harness, pH, biological oxygen demand (BOD5) and total coliform, were measured over 12 months and the obtained data were compared with the WHO’s and Iran’s drinking water standards. To assess the measured data statistically, SPSS software was applied. From the reported results, the water characterizations of the wells complied with the mentioned standards; however, four of the wells were more prone to supply higher quality water. It is noted that Hg, Cd, and the total coliform of wells were close to the permissible values reported by both the aforementioned standards. Therefore, the water obtained from wells should be disinfected before using and Hg and Cd concentrations need to be monitored regularly to prevent poisoning. Due to the rapid movement of pollutants in karst areas, it is very important to detect their presence in the water resources over time. Consequently, continuous monitoring and sampling is one of the most important protection dealings for karst aquifers.

Detection of Groundwater Quality Changes in Minia Governorate, West Nile River

“…in addition to the data collected from unpublished report and studies we get from Egyptian Ministry of Water Resources and Irrigation. These factors are important for determination of groundwater quality [17,18,37,46], the calculated statistics of groundwater quality parameters are shown in Table 2 and their classification according to FAO guidelines for interpretation of water quality for irrigation is shown in Table 3. The geodatabase for these samples was constructed and linked to the digital point data in Shapefile format.…”

“…The evaluation of water quality has a vital rule in the planning, design as well as operation of irrigation systems, especially in arid and semi-arid regions [17,18]. Water quality monitoring methods and degradation through different sources have been widely considered [19].…”

Examining the Role of Clean Drinking Water Plants in Mitigating Drinking Water-Induced Morbidity

“…Contaminated drinking water poses a serious threat to human life across the world. Diseases transmitted due to drinking contaminated water include cholera, diarrhea, typhoid, and dysentery [5]. Waterborne diseases, especially diarrhea, kill approximately one million people globally, and, mostly, children under five years of age are at a higher risk of diarrhea [6].…”
