2 major beaches have a mystery pollution problem, Mount Allison professor says

Two major recreational beaches in eastern New Brunswick have a fecal pollution problem that needs solving, says an environmental microbiologist at Mount Allison University.

• Parlee Beach water quality causing worries

Prof. Douglas Campbell says ParleeBeach and Murray Beach have had sporadically high readingsof E.coliand fecal streptococci dating back to at least 2011.

"I don't mean a little bit 50, 60, or 100 times acceptable count levels on certain days," he said Sunday. "Then they drop back down, and they go back up."

'There's a problem'

The numbers were taken from weekly testingdone during the tourismseason by Research and Productivity Council office in Moncton. The province gives colour-coded warnings when the levels are unhealthy, but doesn't publish the actual amounts.

Campbell was approached by community members inthe Shediac areawho were concerned about the pollution, so he began to collect the data through access to information. He will work with the Shediac Bay Watershed Association as he attempts to figure out where the problem originates.

"There's a problem and we have ideas and wedon'tknow why yet."

Though Campbell is shining a light on the issue, it is well known to local beach-goers.In August, the water at Parlee Beachwasrated poor more days than it wasrated good.

In January, Campbellplans to assign students in his environmental microbiology class to assemble the data and attempt to correlate it with events, currents, rainfall and tides. A separate geographic informationsystems class will also attempt to solve the mystery.

Campbell notes that the problem doesn't seem to stretch down to the Nova Scotian shore.

"This is not strait-wide contamination of the entire water body," he said. "It is somewhat localized."

He said part of the problem is that the testing takes two days, so you're "always looking in the rearview mirror." There are clues that can be looked for, however.

People or other animals?

Aside from looking for specific weather events or problems with sewage handling stations, researcherscan look at the level of E. coli, which diminishes quickly in salt water, as opposed to the fecal streptococcus, which persists.

"We're going to try to see if we can look at the ratios of persistent streptococcus to transient E. coli."

They'll also try to determine whether the waste is predominantly from peopleor from other animals. There have been concerns from some residents that the areais overdeveloped.

Campbell said despite the dour subject matter, it's an exciting opportunity.

"From a pedagogical point of view, I think it's going to be great," he said. "I wish we weren't doing it, but wow, what a chance for our students to really sink theirteeth into something."
