Estrogen-like and dioxin-like organic contaminants in reclaimed wastewater: transfer to irrigated soil and groundwater
In semi-arid regions, treated wastewater reuse for irrigation is a common practice since wastewater is considered as a non negligible water resource in these areas. However, treated wastewater contains traces of organic compounds which may contaminate the receiving environment i.e. soil and groundwater. Some of these organic compounds have the ability to bind to estrogen receptor (ER) or dioxin ...

Irrigation of certain Mediterranean plants with heavy metals
The ability of some Mediterranean plant species to absorb heavy metals present in wastewater from treatment plants is researched. Their tolerance to high concentrations of heavy metals is also assessed. Myoporum sp., Nerium oleander and Geranium sp. were irrigated with wastewater, normal irrigation water, and irrigation water enriched with metals. The concentration of metals in the wastewater, ...

Groundwater quality assessment and its suitability for agricultural purposes in the Behbahan Plain, SW Iran
Groundwater is the main agricultural water resource in arid and semi-arid regions, so, preserving it is extremely important. In this study, groundwater quality was assessed for irrigation, using the principal chemical and physical quality parameters from 30 wells in the study area. Groundwater classification on the basis of electrical conductivity reveals that more than 85% of the samples taken ...

Heap Leach Pad Monitoring - Case Study
2D Electrical Resistivity Imaging Objective Study was performed at a Heap Leach Copper Mining site in Chile to determine the impervious zones for the irrigation. The first base survey is performed to locate the impervious zones to be able to improve irrigations. The second monitoring survey is performed after 50 days of irrigation through drilled two boreholes to observe the improvement of ...

Sensitivity analysis using a diffuse pollution hydrologic model to assess factors affecting pesticide concentrations in river water
We quantitatively evaluated the factors that affect the concentrations of rice-farming pesticides (an herbicide and a fungicide) in river water by a sensitivity analysis using a diffuse pollution hydrologic model. Pesticide degradation and adsorption in paddy soil affected concentrations of the herbicide pretilachlor but did not affect concentrations of the fungicide isoprothiolane. We attributed ...

Reducing agriculture’s water footprint
Decentralized Water Reuse Can Help Preserve Sources of Fresh Water As the world population grows, so does the demand for food and the need to grow more crops. In many regions of the world, water has become a scarce resource, with supplies affected by climatic changes. Not only does water scarcity limit farmers’ ability to irrigate their crops, but overdrawing groundwater supplies for ...

Senix Water Level Sensors Drive Irrigation Automation Project
Australia’s Water Crisis Irrigation management is serious business in Australia especially within the Murray-Darling Basin, a 1,000,000 square kilometer watershed that is home to Australia’s most productive agricultural land. The basin’s 23 rivers have some of the lowest and most variable flows in the world. A massive system of dams, lakes and canals stores water from ...

Use of domestic sewage effluent for sustainable production of vegetable in Kashmir valley
Trace metals in discrete portions of knoll kohl were evaluated along with chemical composition of sewage effluent, irrigation water, and soil. High nutrients, Fe and Mn levels were noticed in the sewage effluent, whereas irrigation water showed recommended norms. Knoll kohl grown on sewage-irrigated soil accumulated sufficiently good amount of trace metals available to consumers. This study also ...

Spatial variation in irrigation demand and supply across canal commands in Punjab: a real integrated water resources management challenge
The Indus Basin Irrigation System (IBIS) is more than a century old. Water allowances and canal water distributions responded to increasing crop water requirements in a southward direction, e.g. higher water allowance in Sindh as compared to Punjab. But within a province, the canal water supplies do not address the issue of difference in irrigation demand. The consequence is unprecedented ...

Efficient water conservation in agriculture for growing urban water demands in Jordan
A significant worldwide challenge is to increase the food supply to accommodate a population growing to 9,000,000,000 in the face of climate change. Per capita water supply in Jordan is among the world's lowest. Despite this scarcity, three-quarters of Jordan's water use is consumed by irrigated agriculture, while producing low economic values from additional water used compared to urban uses. ...
