Drinking water supply of Southern Sardinia is majorily based upon rainwater. The quality of the collected raw water is strongly influenced by a number of environmental factors and safeguarding the overall quality of the raw water and the respective seasonal and event-driven fluctuation is paramount. The most productive water collection area is well known for its polymetal deposits. In the framework of the cooperation between EAF and Environmental Institute the sediments of the major reservoirs have been systematically studied for metals and nutrient elements and the lower lakes Sa Forada and Simbirizzi for pesticide residues and other persistent organochlorine compounds. High metal concentrations were encountered in the upper lakes, pesticide residues are present as well as the major PCB's at moderate concentrations.
