Results of a monitoring project for the water quality of three important rivers of western Greece (Acheloos, Louros and Acherontas) are presented in this paper. The results include the concentrations as well as the temporal and spatial distributions of nitrates, nitrites, phosphates, ammonia and...

The formation of chlorination by-products (CBPs) was investigated by bench-scale chlorination experiments with surface waters from different sources in Lesvos island, Greece. The main factors studied were organic matter content of water (expressed as UV-272 absorbance), time and chlorine dose. The...

Pollutants posing health risks to human health and to the aquatic environment often occur in drinking and surface waters, as a result of disinfection practices, agricultural and industrial activities, wastewater discharges. Toxic pollutants belong to different chemical categories, including...

A pilot-plant study was carried out with the water supply to Athens water works filtered through a granular activated carbon (GAC) filter- adsorber. The objective of this study was to evaluate the performance of GAC for the removal from drinking water of the two main groups of disinfection by...

The results of a research study about the groundwater quality in western Thessaly, that took place during the period 2001-2002, are presented in this paper. The study included two samplings during May and August of 2002. In May the water table is at high level while at the end of the summer the...

In the context of a research program regarding water quality management and protection plan for Lake Plastira, one of the main tasks was the establishment of a sound relationship between the minimum water level and the trophic state of the lake. The study involves the application of a eutrophication...

The Gulf of Astakos is a very important embayment of the Ionian Sea, as it offers an ideal environment for extensive aquacultures with tourism, agriculture and commercial activities. In view of the need for sustainable development of the region, the state of the gulf's quality was assessed on the...

The levels and the distribution of metals, hydrocarbons and organochlorine compounds were studied in mussels (Mytilus galloprovincialis) and surface sediments collected from Thermaikos gulf in March 1999. Hydrocarbon values were indicative of moderate pollution, whereas in some cases clear evidence...

The sustainable management of water resources often requires the identification of wastewater as a valued source of water. Although the benefits of wastewater reuse and reclamation have increased significantly in Europe because of the advances in effectiveness of wastewater treatment and...

The establishment of the Wastewater Treatment Plant of Athens is considered as the main factor contributing to the improvement of water quality and recovery of the marine ecosystem in Saronicos gulf as it removes significant percentage of pollutants entering the gulf, including heavy metals. The...
