A spatial analysis of private well water Escherichia coli contamination in southern Ontario.
Research to date has provided limited insight into the complexity of water-borne pathogen transmission. Private well water supplies have been identified as a significant pathway in infectious disease transmission in both the industrialised and the developing world. Using over 90,000 private well water submission records representing approximately 30,000 unique well locations in south-eastern On...
متن کاملBlue babies and nitrate-contaminated well water.
The use of nitrate-contaminated drinking water to prepare infant formula is a well-known risk factor for infant methemoglobinemia. Affected infants develop a peculiar blue-gray skin color and may become irritable or lethargic, depending on the severity of their condition. The condition can progress rapidly to cause coma and death if it is not recognized and treated appropriately. Two cases of b...
متن کاملNITRATE CONTAMINATION IN OREGON WELL WATER : GEOLOGIC VARIABILITY AND THE PUBLIC ’ S PERCEPTION 1 Aaron C . Kite - Powell and Anna
Approximately 4.5 million people in the United States who rely on well water are exposed to nitrate-N concentrations exceeding the 10 mg/l standard. In this study in the Southern Willamette Valley in Oregon we reassessed nitrate-N in rural wells sampled in 2000-2001, compared nitrate-N concentrations among geological units, and surveyed residents about their perceptions of well water quality. N...
متن کاملEstimation of nitrate concentrations in well and spring water using ANFIS and SVM models
Groundwater contamination by nitrate is a globally growing problem due to the population growth and increase of demand for food supplies.Increasing nitrate concentrations in soil solution and leaching into the ground water table cause water pollution and disturbs the ecological balance. In addition to natural nitrogen cycle, nitrate can be entered to soil and water from the human waste, urban a...
متن کاملInfluences on the water testing behaviors of private well owners.
Many private wells in the United States and Canada already are contaminated, or are at risk of contamination. Regular testing for pathogenic bacteria is one of the most concrete measures well owners can use to determine whether or not their drinking water quality is safe. This study explored the factors and causal relationships that influence well owner water quality testing behavior. In-depth,...
