The New Brunswick government will update the water quality testing and rating system by beach season after a "breakage" in the system resulted in incorrect swimming conditions being reported for Parlee Beach last summer, Environment Minister Serge Rousselle announced Monday. Rousselle admitted there were three weeks when the water quality at the province's most popular beach should have been rated poor, and it wasn't, putting beachgoers at risk for illness and disease. The rating errors came about because the results of the three bacteria level tests done in the Shediac Bay watershed at the beginning of every week were averaged out "for one reason or another," instead of the worst one being used to determine the rating, Rousselle said. ​"There was effectively a mistake done," he said during a news conference in Moncton. "So basically there was no … order to change the system. It is just that somebody by mistake did change the system."..... http://www.cbc.ca/news/canada/new-brunswick/parlee-beach-water-quality-serge-rousselle-1.3968708
