Groundwater at historically low levels

The only well in the Withlacoochee, Little, or Alapaha River watersheds that seems to be instrumented for near-realtime depth measurements is in Valdosta. That well is now at historic lows, compared to 55 years of back data.

On the graph to the right, the black triangle in the middle of the green is the median over those 55 years since 1957. The green is 25th to 75th percentile. The yellow is 10th to 24th percentile. The red is below 10th percentile. I’m guessing below the red means never been seen that low before in that month.

The current depth shown, 137.52 feet below the surface on 26 April 2012, is not the lowest ever seen, which was 152.31 feet on 19 September 1990. But apparently it is lower than seen before for April.

Maybe we should think about water conservation more frequently than just when Valdosta’s water pumps have problems. Not just for watering lawns; also for agriculture and silviculture. Maybe we should try to plant crops that don’t require as much irrigation, or plant them in ways that don’t lead to so much evaporation. Maybe we should be more careful about clearcutting trees, which causes rapid runoff that doesn’t get back into the groundwater as much. Maybe we should think about how much growth do we want.

Groundwater levels: red

In case anybody thinks the recent rains have done away with the drought in Georgia, take a look at this USGS map of groundwater levels today:

USGS Active Groundwater Network map 18 April 2012
Legend for USGS Active Groundwater Network map 18 April 2012

South Georgia, all red and orange. Here’s more detail.

It’s also worth remembering that while our Floridan Aquifer does recharge somewhat, that much of its water has been there since the last ice age. So if we keep mining water at a rapid rate, the aquifer will keep falling.

Glyphosate found in all samples of urine, many times drinking water limit

Mike Barrett wrote for NaturalSociety 26 January 2012, Monsanto’s Infertility-Linked Roundup Found in All Urine Samples Tested,
A recent study conducted by a German university found very high concentrations of Glyphosate, a carcinogenic chemical found in herbicides like Monsanto’s Roundup, in all urine samples tested. The amount of glyphosate found in the urine was staggering, with each sample containing concentrations at 5 to 20-fold the limit established for drinking water.
So, we now know what pesticides are doing to bees. What are they doing to humans? Well, we know that, too: lower IQ in children, organ disruption, miscarriages, birth defects, and infertility.

11 year old is onto Monsanto and how to fix the food system

The “dark side of the industrialized food system.” as related (accurately) by Birke Baehr at TEDxNextGeneration Asheville.
Conventional farmers use chemical fertilizers made from fossil fuels. Then they mess with the dirt to make the plants grow. They do this because they’ve stripped the soil from all nutrients from growing the same crop over and over again. Next more harmful chemicals are sprayed on fruits and vegetables. Like pesticides and herbicides to kill weeds and bugs. When it rains, these chemicals seep into the ground, or rise into our waterways, poisoning our water, too.
His personal goal:
A while back, I wanted to be an NFL footall player.
I decided I’d rather be an organic farmer instead.
[applause]
That way I can have a greater impact on the world.
He’s got a turn of phrase:
We can either pay the farmer, or we can pay the hospital.

Toxic corn and cotton pollute our streams

Steve Connor writes in The Independent 28 Sep 2010 that GM maize ‘has polluted rivers across the United States’:
An insecticide used in genetically modified (GM) crops grown extensively in the United States and other parts of the world has leached into the water of the surrounding environment.

The insecticide is the product of a bacterial gene inserted into GM maize and other cereal crops to protect them against insects such as the European corn borer beetle. Scientists have detected the insecticide in a significant number of streams draining the great corn belt of the American mid-West.

The researchers detected the bacterial protein in the plant detritus that was washed off the corn fields into streams up to 500 metres away. They are not yet able to determine how significant this is in terms of the risk to either human health or the wider environment.

This is the same “gene from the bacterium Bacillus thuriengensis (Bt)” used in Monsanto’s RoundUp Ready cotton and peanuts and soybeans. Since Continue reading →

2,4-D: Back to the Past

So, having just spent a decade breeding mutant superweeds by pouuring pesticides on crops, what’s the recommended future of weed science?

Pour pesticides on crops until they breed more mutant superweeds.

So what is our old friend 2,4-D, which used to be commonly used back in the 1980s? Continue reading →

Farmland for Food, Wildlife, Flood Control, Air Quality, and Agrotourism

Gretchen found this one, too (think I can get her to blog?). Judi Gerber writes about Why Saving Farmland Is So Important:
…without local farms, there’s no local food, or, as the American Farmland Trust (AFT) puts it: “No Farms, No Food.”.

And it’s not even just food:

Farmland is green space, even though most people don’t think of it that way. It is a significant contributor to environmental quality. As AFT states, “Farm and ranch lands provide food and cover for wildlife, help control flooding, protect wetlands and watersheds, and maintain air quality. They can absorb and filter wastewater and provide groundwater recharge. New energy crops even have the potential to replace fossil fuels.”

And there’s more:

Farmland provides fiscal stability to local governments and boosts the economy. It does this by contributing to a community’s infrastructure and helps a local economy through sales, job creation, and support services or businesses.

One of the most unique of these support services is tourism, or more specifically, agri-tourism. There are plenty of places that people visit to see rural scenery or to enjoy the food or drink of a specific region including the wineries in California’s Napa Valley, or popular farm stays like those found in Italy, and increasingly, here in the United States.

There are some plans afoot about agrotourism in Lowndes County.

Lowered Beaver Pond

Did the great beaver dam pipe experiment succeed?

Pipe

Why yes, yes it did. You can see one of the pipes underneath the second log. And the water in the beaver pond is clearly lower.

Maybe the beavers won’t gnaw down as many trees. Gnawed

Cancer in the Air, Food, and Water

Lyndsey Layton writes in the Washington Post that:
An expert panel that advises the president on cancer said Thursday that Americans are facing “grievous harm” from chemicals in the air, food and water that have largely gone unregulated and ignored.
Somebody noticed!

The President’s Cancer Panel called for a new national strategy that focuses on such threats in the environment and workplaces.

Epidemiologists have long maintained that tobacco use, diet and other factors are responsible for most cancers, and that chemicals and pollutants cause only a small portion — perhaps 5 percent.

The presidential panel said that figure has been “grossly underestimated” but it did not provide a new estimate.

“With the growing body of evidence linking environmental exposures to cancer, the public is becoming increasingly aware of the unacceptable burden of cancer resulting from environmental and occupational exposures that could have been prevented through appropriate national action,” the panel wrote in a report released Thursday.

Federal chemical laws are weak, funding for research and enforcement is inadequate, and regulatory responsibilities are split among too many agencies, the panel found.

The problem is not too many agencies. Here’s the problem: Continue reading →
