300A: Lake Simcoe: the Urban Solution to Phosphorus Pollution

October 01, 2019

2:30PM - 3:00PM

Preliminary research of phosphorus-loading figures has been done using the Rural-Urban Transect planning tool. It relied on several decades of phosphorus measurements for Lake Simcoe, and assessed the differences in P-loading across the watershed.  The use of the Transect in this preliminary study reveals: the overwhelming extent of “sub-urban” as the development pattern within the watershed, the disproportionate impact of this pattern for P-loading, the predominant sub-urban contribution to the phosphorus problem on both a watershed and household basis, and urbanism as a possible solution to phosphorus pollution.
