Abstract
A deterministic lake dose calculation model has been applied to estimate the quantity of Ca carbonate-based material needed to achieve a desired initial water chemistry in a whole lake treatment of two Adirondack acid lakes. The study lakes were treated with calcite during May 30–31, 1985.
The model accurately simulated laboratory column water chemistry profiles (spatially and temporally) and dissolution efficiencies; however, the model predicted conservative efficiencies for the study lakes. Time-series water chemistry profiles of the lakes suggest that epilimnetic mixing extended suspension time of fine calcite particles, and that atmospheric carbon dioxide intrusion rate was greater than expected. The combination of these factors enhanced dissolution efficiency.
