Holiday destinations in the EU receive every summer an increasing number of tourists searching to relax and enjoy their leisure time with their families and friends. Swimming in our seas, rivers and/or lakes is one of the most popular activities and the quality of such waters is, thus, of uttermost importance for the EU. Sewage and water draining from farms and farmland are the main sources of pollution, which can be increased due to floods and heavy rains that pour wastewater into rivers and seas. The European Environment Agency (EEA) and the European Commission publish the annual European bathing water quality report to help citizens stay informed about the quality of EU waters. In this context we have chosen Wastewater treatment as the IATE Term of this week!
