Groundwater microbial community samples are traditionally collected using pumping techniques optimized for groundwater chemistry assessment although the impact of groundwater pumping parameters on apparent bacterial community structures (BCS) is not really known. We therefore studied the impact of pumping lift, flow regime and tubing material on BCS, which were analyzed by terminal-restriction ...

INTRODUCTION A significant proportion of water for human consumption has an underground origin becoming 80% in Chilean rural areas where profound wells represent the only search of water for human and animal beverage. AIM To study the microbiological quality of water from agricultural land for livestock production in the province of Valdivia (40°S), Chile and its potential impact on human hea...

Natural gas has become a leading source of alternative energy with the advent of techniques to economically extract gas reserves from deep shale formations. Here, we present an assessment of private well water quality in aquifers overlying the Barnett Shale formation of North Texas. We evaluated samples from 100 private drinking water wells using analytical chemistry techniques. Analyses reveal...

In several endemic fluorotic zones of rural India, home-made parboiled rice is the main staple. Studies were therefore conducted to investigate whether any relationship exists between the concentration of fluoride in the water used for parboiling paddy, and in the parboiled rice. Parboiled rice (PBR) was prepared in the laboratory using water from different origins (rivers, open wells, tube wel...

the activity concentrations of 235u, 232th, 226ra, 40k and 137cs in ground and surface of drinking water resources in iranian city of arak were determined by gamma ray spectrometry with ahpge detector setup, coaxial p type and 8192 channels mca. the water samples differed in radioactivity content depending on their origin and place. in the drinking water samples from aman abad, mobarak abad, an...

Generic Escherichia coli was isolated from surface water and groundwater samples from two dairies in Northern California and tested for susceptibility to antibiotics. Surface samples were collected from flush water, lagoon water, and manure solids, and groundwater samples were collected from monitoring wells. Although E. coli was ubiquitous in surface samples with concentrations ranging from se...

In Northern Thailand, incidences of fluorosis resulting from the consumption of high-fluoride drinking-water have been documented. In this study, we mapped the high-fluoride endemic areas and described the relevant transport processes of fluoride in enriched waters in the provinces of Chiang Mai and Lamphun. Over one thousand surface and sub-surface water samples including a total of 995 collec...

Süt, yaşamın her evresinde önemli bir besin kaynağıdır. Sütün bileşimi, kalıtımsal, fizyolojik ve çevresel faktörler ile yetiştirme koşullarına bağlı olarak büyük ölçüde değişir. Kaliteli süt üretimi, ekonomik anlamda sağlık açısından çok önemlidir. Günümüzde endüstrideki hızlı gelişmeye ortaya çıkan çevre kirliliğinin olumsuz etkilerinden birisi de insan hayvanların ağır metallere maruz kalmas...

Abstract: Background and Aim of the study: The landfill leachate is contains various contaminates that can effect on quality of surface water and wells. In this study influence of the leachate from Albourz landfill in Qom (Qom, Iran) was investigated on quality of groundwater. Material and methods:   In this experimental study, Samples were collected from wells around the landfill site. Va...

Vulnerability assessment has become an important element for wise resource management and land use planning. This work examined the sensitivity of karstic aquifers, in the area of Irbid governorate northwest Jordan, to surface contamination by applying the EPIK method, and then compared this susceptibility evaluation to water-chemistry data collected from wells and springs within the area. An a...
