Groundwater is one of the most important resources of water in the world. Studies show that low rainfall, persistent droughts, and over-exploitation have caused economic and environmental damage. Therefore, this study was conducted to evaluate the effects of rainfall and drought on the groundwater of Kashmar plain as one of the most important fertile plains of Khorasan Razavi in eastern Iran,...

Alkylphenol polyethoxylate (APEO) derivatives, such as nonylphenol monoethoxylate (NP1EO), nonylphenol diethoxylate (NP2EO), nonylphenol (NP) and octylphenol (OP), have been detected in the surface water, sediment, food and groundwater of numerous countries. Because groundwater is the main source of water for pig herds, the aim of this study was to measure the concentrations of APEO derivatives...

Leachate and groundwater samples were collected from Vendipalayam, Semur and Vairapalayam landfill sites in Erode city, Tamil Nadu, India, to study the possible impact of leachate percolation on groundwater quality. Concentrations of various physicochemical parameters including heavy metals (Cd, Cr, Cu, Fe, Ni, Pb, Fe and Zn) were determined in leachate samples and are reported. The concentrati...

Flooding’s impact on shallow groundwater is not well investigated. In this study, we analyzed changes in the depth and quality of a regional shallow aquifer in the 10.9 × 104 km2 Sanjiang Plain, Northeast China, following a large flood in the summer of 2013. Pre(2008–2012) and post-flood records on groundwater table depth and groundwater chemistry were gathered from 20 wells across the region. ...

Data collected for 35 yr from a 1790-ha strip mine reclamation site in Fulton County, Illinois, where biosolids were applied from 1972 to 2004, were used to evaluate the impacts of long-term biosolids application on metal concentrations in groundwater. Groundwater samples were collected between 1972 and 2006 from wells installed in seven strip-mined fields treated with biosolids at cumulative l...

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...

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...

Introduction: Being located in an arid and semi-arid region, Iran has always faced with limited water resources. As groundwater extraction has now exceeded the permitted limits all over Iran and the country faces considerable constraints in developing groundwater resources, severe water crisis looms large in the horizon. In this regard, a quick solution should be considered to supply water from...
