Evaluation of the microbiological quality of wastewater effluent-irrigated maize
Background and Aim: Water crisis in many regions of the world especially arid and semi-arid areas such as Iran, is an important obstacle for socioeconomic development and food security. Under such circumstances, wastewater reuse in agriculture can be regarded an important alternative water source. However, treated wastewater may contain some types of pathogenic microorganisms which can threaten...
متن کاملMonitoring Shallow Groundwater Nitrogen Loading from Dairy Facilities with Irrigated Forage Crops
California’s dairies are the leading confined animal industry in the state. A majority of these family-owned dairies with an average herd-size of nearly 1,000 animal units are located in low-relief valleys and basins. Little is known about the impact of traditional and proposed dairy farming practices on water quality in the extensive alluvial aquifers underlying these basins. We have recently ...
متن کاملDairy Factory Wastewaters, Their Use on Land and Possible Environmental Impacts – A Mini Review

This review investigates dairy wastewaters, factors affecting their composition, some probable effects on land and compounds that may be used to trace the migration of pollutants...
متن کاملTitle:Long-term Transformation and Fate of Nitrogen in Mound-type Soil Absorption Systems for Septic Tank Effluent
Background/Need: The potential for groundwater contamination by fixed nitrogen forms originating from septic tank soil absorption systems is a widespread and growing concern. This concern is exacerbated by significant difficulties and uncertainties in predicting the transformations and fate of nitrogen in any given soil-based wastewater infiltration system. Monitoring to evaluate the extent to ...
