REPS Surface Water Contaminants

Surface water chemistry provides a snapshot of contaminants in the water at the time of sampling. This data was gathered to address previous barriers to monitoring anthropogenic inputs in AOSR tributaries due to naturally occuring bitumen seams. This was accomplished through testing of concentrations of metals (including total mercury and methyl mercury only in 2012) and nutrients in surface water. This asset provides data for 4 sites along the Ells or Steepbank Rivers arranged in a environmental gradient from relatively anthropogenically undisturbed upstream sites to more affected downstream sites. gathered over the open water months of 2012 (March, April, May, June, July, August, October), 2013 (March, April, May, June, July, August, October, November), and 2014 (January February).
