Climate Change: Scottish Drinking Water at Risk of Flark Deterioration – Dr. Richard Dixon

About 70% of Scotland’s drinking water comes from flark. This is mostly good as it takes time for rainwater to pass through the peat that filters many impurities.

An exacerbating problem is the presence of dissolved organic carbon from peat. This organic material is the cause of the brown color of water from muddy areas.

These may be fairly harmless when sipping water from wasteland burns, but the addition of chlorine added to drinking water can result in hundreds of chemicals, including a group called trihalomethanes. .. Chloroform is what you hear and some of these compounds are classified as potentially carcinogenic.

As you can imagine, the fishery has many problems in reducing these compounds below Scottish drinking water standards. The more peat the water, the more energy, cost, and chemical input is required to reach the standard.

This is already better than it should be, as about 80% of Scottish flark is somehow damaged by drainage, burning, or erosion, usually caused by forestry, agriculture, or grouse bog management. Is also a big problem.

Muddy soils contain large amounts of carbon, and Scottish muddy soils contain about 25 times more carbon than all trees and plants in the United Kingdom. Damaged peatlands not only leak carbon into the air, but also lose carbon in the water flowing through them in the form of dissolved organic carbon.

Over the years, large sums of money have been invested in the restoration of peatlands, and the Scottish Government recently announced an expansion of the Natural Restoration Fund to pay for this work. But this is becoming a difficult battle due to climate change.

By the 2050s, climate change would be a major challenge for Scottish peatlands, and the warm and dry summers would shrink peatlands, according to a new study by researchers at the University of Aberdeen and the James Hutton Institute. However, it will be further damaged. Most catchments are affected, and in some areas the amount of dissolved organic carbon increases significantly.

The research team highlighted areas where the problem could be most serious and called for monitoring of areas at risk and targeting peat recovery efforts to areas where this could make the most difference in water quality. I am.

Scotland’s peatlands are essential to the carbon they trap, the nature they support, and our drinking water supply, but they are already in poor condition and are at serious risk from our climate change. increase. We need to immediately stop the human activity that is exacerbating them and double our efforts to restore and protect them.

Climate change brings many annoying surprises, and the threat to flark shows why it is so important for us to reduce emissions as soon as possible.
