Monitoring of Fresh Water Quality

Updated 2013-01-26

Fresh water quality monitoring program is designed to collect long term water quality data from lakes and rivers. It serves EU obligated data collection among other interests. The data is used to detect variation in time in the measured variables and to assess the physiological and chemical state of the water body. The program is managed by the Finnish Environment Institute (SYKE). Regional centres for economic development, transport and the environment are responsible for the field work needed for maintaining the monitoring stations. Monitoring frequency varies between locations from annual to once in three, six or 12 years.

This is a National Implementation Plan (NIP) project

Methods & Procedures

Procedures and methodology used for, e.g., sampling and sample storage, sample pretreatment, extraction and analysis, including which laboratories are involved, references to methods employed, etc.

Surface water temperature is measured daily during the ice-free season at 30 stations (5 stations north of Arctic Circle). Water temperature is measured by digital thermometers. The sensor, which is fixed at a 1 to 2 m long cable, is placed at a depth of 0.2 m. Chemical analysis is conducted from water sample taken every year, or once in three, six or 12 years depending on the location priority.

Additional Information

Is this a bi- AND multi-lateral project (i.e. a project involving cooperation between different countries)?
