Abstract Groundwater pollution, and the same pollution with sewage water resulting from improperdisposal by correct scientific methods, is one of most dangerous environmental disastersthat affect humans in particular environment general, as groundwater considered important resources, especially dry semi-arid surface areas. Study contamination wells E. coli bacteria a number ground wells, 70 reg...

BACKGROUND The implementation of treated municipal water systems in the 20th century led to a dramatic decrease in waterborne disease in the United States. However, communities with deficient water systems still experience waterborne outbreaks. In August 2004, we investigated an outbreak of gastroenteritis on South Bass Island, Ohio, an island of 900 residents that is visited by >500,000 person...

Groundwater contaminant source identification is an endeavor task in highly developed areas that have been impacted by diverse natural processes and anthropogenic activities. In this study, groundwater samples from 84 wells the pilot promoter region of Yangtze River Delta integration demonstration zone eastern China were collected then analyzed for 17 quality parameters. The principal component...

The presence of pharmaceutical compounds in the whole environment is a growing concern. These might be present effluents wastewater treatment plants and, hence, irrigation with treated sewage may source groundwater pollution. volcanic aquifer that lies NE Gran Canaria (Spain) was studied to address relationship occurrence and golf course has been irrigated regenerated water since 1973. Of 14 an...

Hormozgan Province is located in the south of Iran bordering the Persian Gulf. In this area, malaria is still considered a major health problem. In the province, eleven species of Anopheles were identified: An. pulcherrimus, An. sergenti, An. apoci, An. multicolor, An. subpictus, An. turkhudi, An. fluviatilis, An. stephensi, An. d'thali, An. superpictus, and An. culicifacies, among which only t...

Complaints associated with land-applied sewage sludges primarily involve irritation of the skin, mucous membranes, and the respiratory tract accompanied by opportunistic infections. Volatile emissions and organic dusts appear to be the main source of irritation. Occasionally, chronic gastrointestinal problems are reported by affected residents who have private wells. To prevent acute health eff...

During floods, human exposure to pathogens through contaminated water leads to the outbreak of epidemic diseases. This research presents the first extensive assessment of surface and groundwater samples collected immediately after a flood (December 2015) and post-flood (April 2016) from the Adyar River of Chennai, a major city in India, for major ions, trace metals, bacterial population, and pa...

lack of sewage collection systems, percolation of surface waters, and seepage of wells have raised the groundwater table in shiraz area in the south of iran. the growing population generates environmental pollution resulting in the degradation of the quality of surface and groundwaters used for agriculture. inorganic and organic pollutants have been traced in shiraz water resources. heavy metal...

in this study, technical and operational issues of 45 qanats in hamadan, semnan and khorasan razavi provinces were studied and executive strategies to improve water management in qanats were recommended. 15 qanats were selected and studied in each of the provinces. discharge, quantity and quality of qanat water, geometric characteristics including longitudinal slope, length, and flow section ar...

One hundred and twenty samples of drinking water sourced from wells and boreholes from eight local governments that comprise Kaduna north senatorial district of Kaduna state were randomly collected and subjected to Arsenic elucidation using standard laboratory method. The wells have the following results; 0.28, 0.25, 0.25, 0.40, 0.20, 0.30, 0.25 and 0.34 mg/L while the results obtained from the...
