Stormflow-dominated loads of faecal pollution from an intensively dairy-farmed catchment.
Rainstorms can flush large amounts of faecal pollution from land sources into water bodies, threatening, particularly, contact recreation and bivalve shellfish harvest. We quantified the faecal pollution loads of stormflows in the Toenepi Stream, draining a catchment in intensive dairy-farming (Waikato Region, New Zealand). In this stream, as is typical, E. coli concentration peaks well ahead o...
متن کاملSpatial assessment of animal manure spreading and groundwater nitrate pollution.
Nitrate concentration in groundwater has frequently been linked to non-point pollution. At the same time the existence of intensive agriculture and extremely intensive livestock activity increases the potential for nitrate pollution in shallow groundwater. Nitrate used in agriculture could cause adverse effects on human and animal health. In order to evaluate the groundwater nitrate pollution, ...

to study the spatial and temporal variation of nitrate pollution in groundwater in the vicinity of zayandehrud river in isfahan province monthly water samples were collected from 100 wells in the study area. the average n03-n concentration ranged from 1.2 to 25.7 mg/l (5.4 to 115.6 mg/i as no3) and average n03-n concentration in groundwater was 9.6 mg/i, which is lower than the standard limit (...
متن کاملSeasonal Assessment of Nitrate, Nitrite, and Heavy Metals Pollution in Groundwater of Ardabil Aquifer, Iran
One of the most important resources for drinking water is groundwater. Recently, the quality of groundwater has been endangered due to several reasons, including human activities, vast agricultural activities, and the discharge of industrial wastewater containing nitrogen (N) and heavy metals. For this study we investigated the values of NO3, NO2, and some heavy metals and analyzed the groundwa...
