For years, I’ve been standing on my deck in San Francisco, looking south to Silicon Valley for innovation in water efficiency. But I’m starting to realize that I might have been gazing in the wrong direction. Maybe I need to turn around and look north, over the spires of the Golden Gate Bridge, toward the Emerald Triangle in Humboldt, Mendocino and Trinity counties, the hotbed of California’s newly legalized commercial cannabis production.
During the long campaign, you ran on a platform of change, and since the election, you have charted a course toward improving our nation’s infrastructure. I urge you to focus some of that change and a significant portion of those infrastructure improvements on the one issue at the center of survival for all Americans, regardless of whom they voted for — water.
It’s no secret that municipalities across the country are facing budget constraints.
It may seem farfetched, but the reality is that many Americans don’t have regular access to clean drinking water.
