The article presents a deposition of ornaments from the Late Nordic Bronze Age period V. An archaeological excavation along with non-pollen Palynomorph (NPP) and pollen ana-lysis has resulted in new knowledge about poorly illuminated tradition spring offerings. With starting point find at Hedegyden this aims to improve understanding depositional practices relation springs. ornaments, but focuse...
Ground water is considered as a valuable resource for drinking, agricultural, and industrial uses. As human activities are known to affect water quality, studies of this source are necessary to maintain quality standards. Despite heavy agricultural and industrial activity in the Lenjanat region (Isfahan), there has been no evaluation of ground water quality in this area.In this research project...
abstract aims: fluoride is one of the anions present in soil and water, and determining its level in drinking water is vital for preventing dental and bone diseases in societies. this research aimed to determine fluoride concentrations in drinking water sources of rural and urban areas of babol city, iran. instrument & methods: this descriptive cross-sectional study was conducted in babol city,...
The chemical composition of water collected from different wells in Ta’if city was evaluated in order to determine the suitability as a potable or at least for irrigation. This study indicated that most of the chemical parameters such as . Ba, Cd, Cr, Zn & Fe do not fall within the permissible limit. Anions varied greatly between water sampled collected from different wells. Clvaried between 32...
OBJECTIVE To assess the contamination level of total and faecal coliforms in water wells and distribution networks, and their association with human health in Gaza Governorate, Gaza Strip. METHODS Data were obtained from the Palestinian Ministry of Health on contamination of total and faecal coliforms in water wells and distribution networks, and on the incidence of water-related diseases in ...
This study was conducted over seven villages near Darbandikhan district including (2) wells and (5) springs. It covers more than 60 km, to assess the suitability of ground water quality for drinking purpose using water quality index through investigating of different wells and springs; this technique is very useful tool for quick assessment for any water system. This was done by subjecting the ...
Recent studies on the contamination of groundwater with human enteric viruses have focused on public water systems, whereas little is known about the occurrence of viruses in private household wells. The objective of the present study was to estimate the incidence of viruses in Wisconsin household wells located near septage land application sites or in rural subdivisions served by septic system...
assessing the quality of groundwater is important to ensure the sustainablesafe use of these resources. however, describing the overall water quality condition isdifficult due to the spatial variability of multiple contaminants and the wide range ofindicators (chemical, physical and biological) that could be measured. therefore, in thiscase study, some water quality parameters including na, mg,...
Waterborne pathogens are known to reside in surface water systems throughout the U.S. Cryptosporidium outbreaks over recent years are the result of drinking water supplied from such sources. Contamination of aquifers has also led to several reported cases from drinking water wells. With high resistance to typical groundwater treatment procedures, aquifer infiltration by Cryptosporidium poses a ...
Shale-gas production using hydraulic fracturing of mostly horizontal wells has led to considerable controversy over water-resource and environmental impacts. The study objective was to quantify net water use for shale-gas production using data from Texas, which is the dominant producer of shale gas in the U.S. with a focus on three major plays: the Barnett Shale (~15,000 wells, mid-2011), Texas...
