Creek study finds ‘super high’ sewage counts at Chedoke falls
(Flamborough Review, Richard Leitner, Dec 14, 2012)
Illegal sewer hookups are once again being blamed as the likely source of “super high levels” of fecal contamination at three escarpment waterfalls along Chedoke Creek.
Biweekly tests by Redeemer University College chemistry students this fall found the worst pollution at Mountview Falls, whose flows run beneath the stretch of Chedoke radial trail where the city installed a new pedestrian bridge in January.
Coliform counts there averaged 342,000 per 100 ml of water and were as high as one million – the latter more than 400 times the provincial limit of 2,400.
Readings for E. coli were also highest there, averaging 550 times the limit for recreational use, as were those for other indicators of sewage, like phosphate, nitrate, ammonium and biological oxygen demand.
Testing at waterfalls to the east – by the escarpment stairs at Cliffview Park and the eastern edge of Chedoke golf course – also found fecal contamination of up to 100 times the provincial limit.
