You are Being Misled

The Billion $ Wastewater Management scheme being foisted on us by our politicians and special interest groups will do more harm than good for the environment!

ARESST response to GSA statement on sediment coliforms




The October 3rd media release(1) by Georgia Strait Alliance (GSA), TBuck Suzuki Foundation (TSF), and David Suzuki Foundation (DSF) presented misinformation suggesting that Victoria’s current system of natural marine treatment needs to be replaced.

In a subsequent October 4th CHEK TV news-cast(2), retired UVic microbiologist Dr. Ed Ishiguro presented informal test results that were neither scientifically peer-reviewed nor published.On the same news-cast, CRD director Judy Brownoff cited his tests to support her promotion of the CRD’s sewage plan.

ARESST offers the following documented clarifications:

  • Dr. Ishiguro, GSA, TSF, and DSF compared(3) fecal coliforms in local marine sediments to fecal coliform water standards (from Health Canada,(4) US EPA, and WHO).
  • They were negligent to apply water quality standards to evaluate sediments.Their claims of contamination and threat to human health are therefore unfounded.
  • Their claim that human fecal coliforms traveled 2-10 km is absurd. The marine environment is hostile to coliforms from the human gut.(5) A peer-reviewed analysis of 1700 samples found no evidence beyond 400 metres of fecal coliforms from Victoria’s outfalls(6).
  • Fecal coliforms from plants and animals exist throughout the marine environment.(7)  Their presence in sediments off William Head or Trial Island is no more related to Victoria’s outfalls than sediment coliforms off Tofino or Alaska.

At an October 9th sewage meeting(8), in response to a query from Director Brownoff, CRD science staff reported no problems with fecal coliforms – thus contradicting Ishiguro, GSA, TSF, DSF, and herself.

The CRD offers many scientific studies online(9) confirming that Victoria’s current method of marine treatment is essentially as effective as secondary treatment. Victoria’s system already meets the objective of the new Federal regulation(10) because there is no evidence of a threat to fish, fish habitat or human health due to consumption of fish from the waters around Victoria.

Citizens should be outraged that the majority of CRD Directors voted NOT to invite experts(11) to explain all this evidence to the sewage committee.

Citizens should be equally outraged that our elected representatives are not using this abundance of scientific evidence to make the case to Ottawa that it is senseless to continue to force Victoria to build a costly and unnecessary land-based treatment system.
