Map of Nose Creek stormwater drainage network summarizing the most relevant manholes tested for the human sewage marker HF183 upstream of the positive outfall site labeled N#1. Note the manholes upstream of N#1 where HF183 was positive and quantifiable (red dots), detectable but not quantifiable (yellow dots), or not detected (green dots). Also note the directional flow of stormwater through the system, represented by drainage networks positive for HF183 (red arrows) as well as stormwater flows with no demonstrable HF183 detection (black arrows). Note that all maps presented were created and co-owned with the City of Airdrie, and have been used with permission.
