Through the construction of drainage ditches. much of the former bog has been convened to agricultural lands and peat has been extracted. The drainage ditches have caused extensive changes to the hydrology and ecology of the bog, including the loss of Sphagnum moss and invasion by birch and aspen. Human activities have potentially contaminated the bog. The large pool of organic matter in Wainfleet Bog can bind/sorb hydrophobic contaminants. Measured as TOC, there are high levels (up to 200 mg/L) of aquatic organic matter (dissolved plus suspended) in the drainage water at Wainfleet Bog. This mobile organic matter may play an important role in flushing contaminants from the bog. Large seasonal fluctuations in TOC are related to climatic and hydrological changes"--Abstract. gccst Water management gccst Wetlands Crowe, Allan, 1952- Canada. Environment Canada.
