T
he sewage debate has been raging in the Capital Regional District for decades. With each passing year, the distinction between political and environmental motives behind a proposed $783-million project grows more difficult to separate. Jay Cullen, a professor at the University of Victoria School of Earth and Ocean Sciences, recently led a CafĂŠ Scientifique talk titled “Victoria’s Sewage Treatment: a Brief History of Slime.â€? The discussion was a part of a free, informal series aimed at bridging the science-to-public gap – something that has been missing when it comes to the highly politicized sewage debate over whether or not the CRD truly needs to change its ways of streaming sewage into the Strait of Juan de Fuca through Clover and Macaulay points. “The CRD operates a world-class program to determine the impact of the effluent on the health of the marine environment and the potential impact on public health,â€? says Cullen, Natalie North whose research is focused on metal Reporting chemistry in sea water. “For the most part, the impact of the effluent on the marine environment, and certainly on public health, is minimal.â€? Cullen does admit the effluent does have some measurable impact on the marine environment. It causes changes in the invertebrates that live in the sediments around the outfalls, reduces species richness and is the source of a greater abundance of organisms able to tolerate high levels organic loading from the outfalls. But the impacts, Cullen says, are reversible and confined to about 200 metres from the outfalls themselves. Cullen agreed to lead the talk based on the false assertions he’s seen people make in the CRD: one of which is that the effluent has no impact whatsoever. The other: that the impact is a devastating environmental disaster in progress. PLEASE SEE: UVic tries to separate poop from politics, Page A8
