SAN FRANCISCO Nearly one-fifth of the raw groundwater used for public drinking water systems in California contains excessive levels of potentially toxic contaminants, according to a decade-long U.S. Geological Survey study that provides one of the first comprehensive looks at the health of California’s public water supply and groundwater.
One of the surprises in the study of 11,000 public supply wells statewide is the extent to which high levels of arsenic, uranium and other naturally occurring but worrisome trace elements is present, authors of the study said.
Public-water systems are required to bring many contaminants down to acceptable levels before supplying customers. But the findings highlight potential concerns involving the more than 250,000 private wells where water quality is the responsibility of individual homeowners, state officials said.
Today, Lake Powell’s vastness is diminishing with water levels falling under 45 percent capacity. The conditions at Lake Powell are beginning to look similar to Lake Mead, the world’s largest reservoir, which sits 180 miles downriver and is also drying up at a shocking pace.
Lake Powell’s “Bathtub ring” now appears 100 feet above boaters
Water levels at Glen Canyon dam have fallen more than 100 feet. The shoreline of Lake Powell now shows a deepening “bathtub ring” – a natural phenomenon that shows how high water levels used to be. This “bathtub ring” now shows in the sandstone walls of the canyon some 100 feet above today’s boaters who must now navigate around emerging islands and mud bogs. Continue reading
As drought, flooding, and climate change restrict America’s water supply, demands from population growth and energy production look set to increase, according to a report from the U.S. Government Accountability Office.
These two changes squeeze our natural water reserves from both directions. The stress is becoming clear and will soon manifest as water scarcity problems all over our country. Continue reading
The geo-political map is set to change. Is the world ready?
There’s a popular geopolitical parlor game called Who will be the next superpower?
While the game excels at triggering a mind-fogging tsunami of nationalistic emotions, it doesn’t shed much light on the really consequential question: What is power?
These are important questions to ponder as, around the world, unsustainable policies from the 20th century are beginning to fail in earnest. What will the future geopolitical landscape look like in their aftermath?
With about half of the country still suffering from extreme drought, farmers and businesses in the Western United States are looking at another hot, dry summer.
And the country’s water risk is a lot worse than most assessments suggest, according to a recent study from the Columbia University Water Center. Continue reading
