31 May, Excursion to Jehander's wetland

Jehander's a large company in the earth moving and construction industry, is planning to clean and store up to 100,000 tonnes of blasted bedrock per year, from Förbifart Sthlm. The explosives used has resulted in high nitrogen content in the wastewater, which will be purified by using a constructed wetland.
