Winter Road Salt – the Next Acid Rain? – May Threaten Adirondack “Queen of American Lakes”

Tendrils of fog curl above the waters of the Queen of American Lakes, as Lake George in New York’s Adirondack Mountains is known.  Biting winds gusted out of the northwest yesterday, and an early snow is forecast for tomorrow.  But for this one afternoon in late fall, cold winds fetching across slate-gray waves have gone…

Stop that Cow: When Ecuadoran Cities Organize to Protect Water Supplies

Arturo Quevedo, the engineer responsible for the watershed protection program for Loja, Ecuador’s municipal water agency, has a kind demeanor. His slightly crooked front teeth are prominent beneath his moustache as he waxes ebullient about clean water percolating through forested slopes, coursing through pipes, and hydrating Loja’s children.

Harmful Algae Blooms Plague Lake Erie Again

Like a cruise ship captain leading a voyage through environmental hell, Phillip Musegaas points out oil slicks, the sewage treatment plant, and the huge pipes where raw sewage flows into the creek every time it rains. He notes…

Counting Water Bugs for Rocky Mountain BioBlitz

Tiny bugs called macro-invertebrates help make freshwater ecosystems tick, and as a team of volunteers found out at Lily Lake in Rocky Mountain National Park, they’re diverse, abundant and just plain cool little creatures. Rachel Harrington, a freshwater ecologist at Colorado State University in Fort Collins, Colorado, led the BioBlitz volunteers in identifying the water…

Leaf Packs Help Measure Water Quality

  We recently covered the expedition to Peru by the Amazon Center for Environmental Education and Research (ACEER) to measure water quality along the new Transoceanic Highway, which will cross South America from east to west when finished. The ACEER team has been using stream surveys and leaf packs developed by the Stroud Water Research…
