NEW AUBURN - With four sand mines in operation within a few miles of New Auburn public schools, district officials have taken extra precautions to keep silica sand out of the building's air system.
Superintendent Brian Henning says the district has been using higher-quality air filters at double the price, spending about $1,500 this school year.
West-central Wisconsin is a hot spot for sand mining and residents have expressed environmental and health concerns about the tiny sand particles generated by mining. The sand is mixed with chemicals in hydraulic fracturing _ a high-pressure process used to extract natural gas and oil from the ground.
Henning tells the Eau Claire Leader-Telegram (http://bit.ly/HjCgBE ) school officials took dust scrapings from the air filters and sent it to a Madison lab for testing. They found a small amount of silica on the filters.
RHINELANDER - Wild Instincts celebrated the release of BBC's "Supercharged Otters," which filmed at Wild Instincts in Rhinelander.
Saturday's viewing at Rouman Cinema in Rhinelander had a complementary showing of the episode.
The episode features otters that spent seven months with Rehabilitation Director Mark Naniot and his team.
The episode gives people a look into the life of an otter.
"Like everything else it's the web of life. Everything's all interconnected and even if it's just the pure enjoyment of watching an otter swim or catch a fish and seeing how playful they are sliding down a mudslide or sliding through the snow that alone is immeasurable really," said Naniot.
