| Abstract | Urban living generates waste that is usually treated to some degree and then discharged into water bodies. Too much waste can pose a risk to aquatic ecosystems and species. Pollutants can remain
environmentally damaging even after passing through conventional sewage treatment. Municipal wastewater, including residential, commercial and industrial wastewater, is the major source of contaminants in the marine environment. In southern Canada,
where most Canadians live, much of the municipal wastewater is treated by reducing some of the oxygen, suspended solids, phosphorus and sometimes ammonia and nitrogen to reduce the environmental impact on the receiving aquatic ecosystems. The map
shows the percentage of the population without access to sewage treatment by ecoregion. |
| Summary | (Plain Language Summary, not published)
The map was originally published online in the Atlas of Canada, 6th Edition as an interactive digital map derived from a shapefile and mapped online
using MapServer, a platform for publishing spatial data to the web. In order to preserve the geographical content of this Edition during its publication from 1999 to 2009 all the maps have been converted from their online interactive form to a raster
and made available in PDF and JPEG. |
