The purpose of this study is to provide a better understanding of the impact of agricultural activities on groundwater quality in a semi-arid coastal environment (Korba, Tunisia). Impacts have been assessed through groundwater samples that were analysed for a range of chemical and biological parameters. Results indicate that groundwater overexploitation for irrigation and fertiliser use have affected the quality of the groundwater not only by direct contamination but also seawater intrusion. The implementation of appropriate regulatory and economic instruments to foster sustainable practices in the agricultural sector have been analysed within the framework of the EC (European Community) FP6 (funding program 6) INECO (Institutional and Economic Instruments for Sustainable Water Management in the Mediterranean Region) Project. Through stakeholder involvement processes, the project analysed issues relating to the regulation and control of groundwater abstractions, the promotion of wastewater reuse, efficiency improvements in irrigation water use, as well as instruments to strengthen the socioeconomic and institutional environment towards better managing and conserving available groundwater resources. © 2012 CIWEM.

The quality of a coastal aquifer (Korba, Tunisia) in a semi-arid agricultural region was studied by the collection and analysis of groundwater samples for their main chemical and biological parameters in relation to the SEQ evaluation system for groundwater quality. Results indicate important anthropogenic deterioration. Most of the samples were unsuitable for drinking-water production; animal drinking and irrigation with these waters will require caution. The high contamination is mainly due to the local intensive agriculture. Based on the objectives-oriented project planning method, regulatory and socio-economic instruments were extensively developed to encourage sustainable agriculture through a participatory exercise. © 2012 Copyright 2012 International Water Resources Association.

The objective of this study is to investigate physicochemical characteristics of sewage sludge taken from the municipal wastewater plant of Chotrana in the capital of Tunisia and to investigate compost made from the sludge (15.29 C/N ratios). A comparative study was made for major nutrient elements or macronutrients (e.g., carbon, nitrogen, phosphorous, potassium) and micronutrient elements (e.g.,manganese andmagnesium). Organic matter concentration at the end of composting was lower in final product. K, Fe, and Mn concentrations were more important inmature compost.Original sludge displays higher C, N, P, Ca, and Mg contents. An important observation was the amount of heavy metals and E.Coli present in the final product is lower than amounts mentioned for waste compost used in French norms, suggesting the final compost may be safe for agricultural use as well. © 2010 DEStech Publications, Inc.

The aim of this study was to evaluate xenobiotics contents (Detergent, heavy metal and chloride) of final compost made from different wastes (Textile sludge, municipal sludge, municipal waste and garden waste). After composting, there was an increase in total heavy metal contents in compost because of loss of mass due to biodegradation of organic matter. In addition, we recorded a slight increase of chloride content. On the other hand, this study demonstrates that aerobic biodegradation has important environmental consequence for detergent contents in the pile that biodegrade in the presence of air during the composting process. However, proper consideration should be given to the compost metal content and further field studies are required to examine the long-term effect of the final product in soils, particularly in relation to biological indicators of soil quality. © 2011 Academic Journals Inc.
