Since discovery of harmful disinfection by products (DBPs) like trihalomethanes (THMs) and haloacetic acids (HAAs) in chlorinated waters the removal of organic DBPs precursors gained priority in drinking water treatment. Historically, coagulation process was arranged to remove turbidity, typically...

The transport of volatile organic contaminant (VOC) mixtures in the unsaturated zone is typically controlled by a combination of transport (i.e., advection, dispersion, and diffusion) phenomena, phase change (i.e., volatilization, dissolution) and reaction processes (i.e., sorption, biodegradation)...

The present paper deals with water quality modification during its stagnation in copper distribution pipes caused by electrochemical corrosion processes. Copper is chosen as plumbing material because of its wide use in drinking water distribution systems all around the world, and because of its...

The Olympic Rowing and Canoeing Center constructed at Schinias, accommodated the rowing and canoe – kayak sprint competition of the 2004 summer Olympic Games. This paper presents the results of a study which aimed at assessing the water quality characteristics, regarding microbial pollution, of the...

The objective of this study was to provide a quantitative description of the impact of converting tropical forests into pastures for cattle grazing in terms of the sediment, nitrogen and phosphorus concentrations at the outlet of a river basin located in North West Costa Rica. The Soil and Water...

The objective of this study was set on three goals: (i) Chemical and radiological characterization and leaching properties of the mixture of fly and bottom ash, (ii) Chemical, radiological and mineralogical characterization of the Kastela Bay sediments, and (iii) Estimation of the influence of...

Speciation behavior of trihalomethanes formation in chlorinated waters due to the effects of bromide is mathematically modeled by a three-tier scheme. Equations for the mole fractions of the mono-, di-, and trihalo-intermediates at each tier level in terms of the initial bromide to chlorine molar...

Salinity is a common problem in Greek islands, especially, during the summer period when the saltwater intrusion becomes more severe due to extensive over pumping. In the past few years, the industrial zone of the City of Herakleio in Crete appears to have an increasing water demand as result of the...

(NMEA) and N-nitrosodiethylamine (NDEA) are highly mutagenic compounds that are suspected of carcinogenic activity to the human body. The aim of the paper is the evaluation of the possibility of N-nitrosomethylethylamine and N-nitrosodiethylamine formation as a result of the reaction of...

Sea eutrophication is a natural process, however in many cases is considered one of the major forms of water pollution affecting coastal areas, lakes and reservoirs all over the world. Many methodologies have been developed for assessing eutrophication and during the last decades, the contribution...
