Water Balance Tecniques Using Stable Isotopes

The acid sensitive lakes program (ASL) was initiated in 1999 to collect baseline environmental data to determine if lakes and catchment soils in the Fort McMurray area were being affected by airborne acid emissions from oil sands operations. In 2002, a stable isotope component was added to the annual ASL lake sampling program, involving collection of water samples from the 50 lakes followed by laboratory analysis of the naturally occurring stable isotopes of water, oxygen-18, and deuterium. This work provides an enhanced perspective of the variability fo hydrological processes that had formerly been a primary source of uncertainty in acid sensitivity modeling efforts.
