Drinking Water: Extreme Weather Events Threaten Quality, Says Report

The greatest risks to water quality come from cumulative impacts of extreme weather events that happen sequentially, like a drought followed by a wildfire followed by a flood, says joint Australian-US study. As climate change likely increases the frequency of extreme weather events, resilience must be built into the management of watersheds and water treatment systems for recovery to happen.

Report: Society's Water Safety Net Is Fraying

US Ports Modernize While Water Supply and Quality Deteriorate

In preparation for the expanded Panama Canal and the prospect of gigantic cargo ships, US coastal cities have entered a frenzy of deepwater port infrastructure refinement complete with federal funding. All the while, water infrastructure funding lags and our water quality (and quantity) deteriorates.

Water, Air Quality Concerns Heighten Conflict Between Pig Farms and Environmental Advocate

Many communities exposed to pollution from large pork facilities are reaching the end of their rope. US pork is a growing industry, but most pigs are raised in factory farms that produce tons of manure and run-off. According the EPA, due to agricultural run-off, over half of America's freshwater is too polluted for use. As a result, many pork farms are being targeted with lawsuits.

Try eel, crab or salmon as an alternative. [Shape]
