Groundwater Quality in Coastal Aquifers in Morocco OceanDocs
Pulido-Bosch, A.; Targuisti, K.; Cerón, J.C.; El Stitou Messari, A J.; El Morabiti, K.; Aoulad Mansour, N..
The results of an initial research carried out in the several coastal aquifers are exposed. The studied areas are situated in the northern most part of Morocco. At the northeast are located the detrital aquifers of Smir and Martil-Alila, and in the northwest is located the detrital aquifer of Charf El Akab. The areas are underlain by detrital sediments of Pliocene to Quaternary age. Generally, groundwater has a high salinity and concentrations moder- ated to high of nitrates. The waters are meanly sodium-chloride type in Smir and Mart il- Alila aquifers. The waters are sodium-chlorid- and calcium-bicarbonate type in Charf El Akab aquifer. The hydrochemical study of the water of the aquifers shows that the salinity is conditioned by human activities (waste...

Groundwater Quality: Ghana OceanDocs
This is one of a series of information sheets prepared for each country in which WaterAid works. The sheetsaim to identify inorganic constituents of significant risk to health that may occur in groundwater in thecountry in question. The purpose of the sheets is to provide guidance to WaterAid Country Office staff ontargeting efforts on water-quality testing and to encourage further thinking in the organisation on waterqualityissues.

TRADABLE PERMITS FOR CONTROLLING NITRATES IN GROUNDWATER AT THE FARM LEVEL: A CONCEPTUAL MODEL AgEcon
Morgan, Cynthia L.; Coggins, Jay S.; Eidman, Vernon R..
Nitrate contamination of municipal and domestic well water supplies is becoming an increasing problem in many rural and urban areas, raising the cost of providing safe drinking water. The objective of this paper is to describe a marketable permit scheme that can effectively manage nitrate pollution of groundwater supplies for communities in rural areas without hindering agricultural production in watersheds. They key to implementing this scheme is being able to link nitrate leaching from nitrogen fertilizer applied to crops at a farm to nitrate levels measured at a drinking water well.
