Green layer of scum on Jones Lake in Moncton not toxic, city says

Much of the surface of Jones Lake in Moncton's west end is covered by a thick, green layer of scum. The city has determined it's "horse hair" algae, also known as "cotton ball" algae. Dan Hicks, the director of parks for the city, says it might not look good, but it isn't toxic to people or pets. "It doesn't cause really human health issues in any great way, but there's certainly an abundance of it in Jones Lake right now," he said.

'Cleaner than ancient arctic ice,' university scientists plan to study Tiny groundwater

'Cleaner than ancient arctic ice,' university scientists plan to study Tiny groundwater

Two University of Alberta scientists gave Tiny Township council a taste of the municipality's superior groundwater while asking the municipality to collaborate on a project they hope to launch next year. William Shotyk and Michael Powell were at a recent committee of the whole meeting to present the work they've done so far studying the artesian spring present in this region of Ontario. "The groundwater has below-detection limits of nitrates and phosphates," said Shotyk, professor and Bocock agriculture and the environment chair. "It's an indication of the water quality. The other perimeter is chloride.

Province 'serious about compliance' at Travellers Rest, P.E.I. wash plant

Province 'serious about compliance' at Travellers Rest, P.E.I. wash plant

A potato wash plant in Travellers Rest is cleaning up its act, and the pressure is on after the province issued a directive letter in mid-January. P.E.I. Potato Solutions is getting ready to open a new, larger facility next month, said co-owner Austin Roberts. Neighbours have made numerous complaints to the provincial Department of Environment as well as Environment Canada regarding the plant’s practices over the years. On Dec. 26, a heavy rainfall, combined with other factors, caused a holding pond containing organic waste from the plant to discharge into the environment.

Decontaminating pesticide-polluted water using engineered nanomaterial and sunlight

Decontaminating pesticide-polluted water using engineered nanomaterial and sunlight

QUÉBEC, Jan. 15 2020 /CNW Telbec/ - Atrazine is one of the most widely used pesticides in North America. Researchers at the Institut National de la Recherche Scientifique (INRS) have developed a new method to degrade it that combines a new nanostructured material and sunlight.  Atrazine is found throughout the environment, even in the drinking water of millions of people across the country. Conventional water treatments are not effective in degrading this pesticide. Newer processes are more effective, but use chemicals that can leave toxic by-products in the environment.
