Abstract

A validation or adaptation of the TEC-PEC values for Switzerland is recommended before SQG can be implemented. Background concentrations can be established on a regional scale when a broad database is available, e.g. 5%-percentile of data. Else the FOREGS (Forum of the European Geology Surveys; www.gsf.fi/publ/foregsatlas) can be used as a rough indicator. A tiered approach that includes an initial comparison against TEC-PEC values and a subsequent consideration of background/natural metal concentrations can serve as a preliminary framework until SQG are implemented in Switzerland. Harmonisation of sampling and pre-treatment methods is required.

Wastewater treatment

Wastewater treatment is a process which removes and eliminates contaminants from wastewater and converts this into an effluent that can be returned to the water cycle. Once returned to the water cycle, the effluent creates an acceptable impact on the environment or is reused for various purposes (called water reclamation). The treatment process takes place in a wastewater treatment plant. There are several kinds of wastewater which are treated at the appropriate type of wastewater treatment plant.

Sewage treatment

Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges. Sewage contains wastewater from households and businesses and possibly pre-treated industrial wastewater. There are a high number of sewage treatment processes to choose from.

Water treatment

Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment. Water treatment removes contaminants and undesirable components, or reduces their concentration so that the water becomes fit for its desired end-use. This treatment is crucial to human health and allows humans to benefit from both drinking and irrigation use.
