Physical disturbance, pollution from agriculture, settlement or industry may affect water quality in our rivers. Management in Norway aims to have a good water environment. Environmental monitoring is required to monitor the water quality and on obtaining information on measures necessary to achieve the goal of good water quality.
The acquisition includes sampling, chemical and biological analyses in Norwegian rivers.
Monitoring environmental toxins in fresh water is a part of the Norwegian authorities' basic monitoring of the environmental condition of water. The intention of the programme is to document the occurrence, levels and accumulation of environmental toxins in Norwegian lakes, as well as to contribute to classifying lakes in accordance with the Water Directive.
The assignment involves sample taking, chemical analyses and reporting.
The intention of the programme is to get information on the occurrence and fate of environmental toxins in the Norwegian fresh water eco-system. The programme involves sample taking and the analysis of samples from different levels in the food chain (abiotic samples, plankton and fish) in a chosen large lake. Environmental toxin levels will also be measured in top predators in a reference lake for comparison. The data acquisition shall provide the basis for assessing the danger to health and the environment and for identifying the requirements for regulating chemicals nationally and/or internationally.
The intention of the sub-programme is to provide information on the occurrence and level of the EU's prioritised environmental toxins in fresh water fish, for classifying the chemical state in accordance with the water regulations. The programme includes the analysis of samples that have been obtained for other activities on behalf of the Norwegian Environment Agency.
Compared with other European countries, Norway has a broad and versatile range of relatively intact hydrometric areas. The extent of the activities that influences the hydrometric areas has however increased. Physical interventions, pollution from agriculture, built-up areas or industry are examples of such activities. The climatic changes are also influencing the Norwegian rivers. The Administrative Authority in Norway aims at having a good aquatic environment. This must be documented by surveillance. The Environmental Protection Authorities also requires comprehensive knowledge about processes related to nutritive substances and environmental poisons in Norwegian rivers, in order to assess how the rivers influence the Norwegian coastal areas, and if measures must be implemented for achieving the goal for a healthy aquatic environment.
The procurement is for sample taking, chemical and biological analyses in Norwegian rivers.
