Role Of Groundwater-Lake Interactions On The Behavior Of Chemicals In A Nearshore Aquifer, Sabina Rakhimbekova
Role Of Groundwater-Lake Interactions On The Behavior Of Chemicals In A Nearshore Aquifer, Sabina Rakhimbekova
Electronic Thesis and Dissertation Repository
It is well recognized that groundwater-surface water interactions play an important role in controlling the flux of groundwater-derived inorganic chemicals to surface waters. While these interactions have been well-studied in marine, and river and stream settings, the influence of these interactions on chemical fluxes to large lakes is poorly understood. Nearshore aquifers adjacent to inland coastal waters, such as the Great Lakes, are characterized by dynamic flow patterns and the mixing of groundwater and lake water, which have distinct chemical compositions. This sets up an important reaction zone in the nearshore aquifer that may modify the fate of groundwater-derived chemicals …
Estimation Of Nutrient Loads From Septic Systems To Tributaries In The Lake Erie Basin, Lauren Oldfield
Estimation Of Nutrient Loads From Septic Systems To Tributaries In The Lake Erie Basin, Lauren Oldfield
Electronic Thesis and Dissertation Repository
Septic systems are often cited as an important source of nutrient loading to surface waters; however, there is limited quantitative evidence supporting this. To address phosphorus (P) load reduction targets for Lake Erie that were set by the Canadian and United States governments, there is a need to quantify the contribution of septic systems to P tributary loads. Doing so is challenging due to the diffuse nature of this nonpoint source, the lack of septic system inventory across Ontario, and the complexity of P transport in the environment. In this study, the artificial sweetener acesulfame, a tracer for human wastewater, …
