Kristen Villebrun and Wendy Bush hoped they wouldn't have to pray for Chedoke Creek, but four years after they first raised alarm about the water's condition, they were part of an Indigenous full moon ceremony to do just that. About 50 people showed up near Princess Point on the dark and frigid Monday evening for the monthly ceremony, which was particularly special as it focused on Chedoke Creek. The body of water that runs into Cootes Paradise had about 24 billion litres of sewage and storm water runoff leak into it due to a gate being left open.
“We tested in 2015 and had 53 milligrams per litre result. Over 20 mg/l needs to be reported to health unit — they advise that a notice should be posted to advise users who may have a medical reason to manage sodium intake — which we did. When we did a test this spring, it came back 120 mg/l. Again, we advised the health unit and posted.”
A handheld ‘tricorder’ that can test for biological contamination in real-time has been the dream of science fiction fans for decades. And UBC Okanagan engineers say the technology is closer to science fact than ever before. Using a small and inexpensive biosensor, researchers in the School of Engineering have developed a novel low-cost technique that quickly and accurately detects cryptosporidium contamination in water samples.
