Inventory of the pollution potential from farms within the Kola River Basin: a mass balance approach
2001 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

Background: Almost all human activities on the Kola Peninsula are close to the Kola River. The Kola River is a provider of water for about 400 000 people. During the 1990s there have been outbreaks of Salmonella and other stomach sicknesses. The water has also at times had nitrate levels that exceeded the drinking water limits for children. It is suspected that the waste from animal farms impact the water quality. The aim of this thesis project is therefore to assess the potential for pollution from the animal farms within the drainage area. Research questions: • What kinds of waste are produced and in what amounts? • What is the polluting potential of the farms? • Risk analysis: How can the potential be realised? Demarcation: The substances in focus are nitrogen, phosphorus and potassium. The farms included in the study are: • The Fur and Cattle Farm Kolskiy - holds foxes, minks (for production of furs) and cows • The Fur and Cattle Farm Murmansk- holds foxes, minks (for production of furs) and cows • The Poultry Farm Murmanskaya - holds layers • The Pig Farm Pridgorodniy - holds pigs • The Poultry Farm Snezhnaya - holds broilers • The Fish Farm Taybola - holds salmon • The Pilot Farm Voschod - holds reindeers and cows Method: A mass balance approach was used. The data was collected with the use of questionnaires, investigative tours and interviews. A literature study was also carried out. Pollution Potential and Risk Analysis: Pollution potential Risk The liquid waste ponds Pond failure High Medium Drainage and leakage Medium High The solid waste and its spreading on the fields High High The organic waste from fur production Medium High The wastewater High High The gas emissions Low High Other activities, the usage of herbicides and other substances Not known High Examples of recommended measures and continued investigations: • Investigate at frequent intervals where the weakest points of the ponds are (major and minor): investigate and apply alternative measures and actions. • With regard to the fur animals, improve the collection system of the waste by collecting the waste more often and making sure that waste does not fall onto the snow. • Develop a water protection strategy for all the farms. • Investigate if there is a way to make the usage of fertilizers more effective in the area. • Continue the water sampling in the creeks to find out the real pollution from the farms. • Carry out ground water analysis, especially on nitrates.
