Easy Fixes: Vinegar and Chickenshit

Two interesting papers in the science lit today on home-brewed solutions to industrial-strength problems. The first: contaminated water can clean itself if simple organic chemicals such as vinegar are added. The second: chicken manure cleans soil that’s been contaminated by crude oil.

The vinegar solution was tested on groundwater tainted by former textiles factories, smelters, and tanneries. The leftovers of these industries produced harmful chromium compounds that cause cancers and all kinds of kidney, liver, lung and skin troubles. But add dilute acetic acid, aka vinegar, and—presto!—the oxidized chromate became non-soluble. That means it’s no longer bio-available and can be left safely in the ground without risk to the surrounding ecosystem. The vinegar feeds and grows naturally-occurring bacteria which then alter the chemistry of the chromium compounds, rendering them harmless.

Good job bacteria!

The chicken guano solution was used on soil contaminated by crude oil spills. Conventional clean-up bears a heavy environmental cost since detergents become pollutants themselves and persist in the environment for a long time. Better to bioremediate: use natural or engineered microbes to metabolize the organic components of crude oil. But too often that requires expensive nitrogen and phosphorus fertilizers with their own hefty environmental price tags (decreased soil quality). But when chicken manure was added to the soil—presto!—nearly 75 percent of the oil was broken down after two weeks. At least 12 different species of oil-munching bacteria liked the chickenshit menu and responded by metabolizing the oil.

Let’s dig back through our great-grandmothers housekeeping diaries and find out what else they (probably) knew that we’ve forgotten?

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
