Mercury through the air into rivers has greatly decreased in recent years 2023-06-05

Good news: “Atmospheric [mercury] deposition from domestic power plants decreased by 91% across the contiguous U.S. from 6.4 Mg in 2010 to 0.55 Mg in 2020.”

Bad news: “Despite large deposition declines, an end-member scenario for remaining exposures from the largest active power plants for individuals consuming self-caught fish suggests they could still exceed the U.S. Environmental Protection Agency reference dose for methylmercury.”

Better with room for further improvement

We know mercury is a problem in the Alapaha River, coming through the air from coal Plant Scherer, north of Macon, Georgia. So by this paper the problem is lessened, but still is a problem.

It’s also a problem on land, for example near the Okefenokee Swamp, where the proposed strip mine may stir up mercury, as mentioned in the Clinch County resolution against that mine and for the Swamp.

You can still help stop that mine.

Hamilton County Planning Commission wants conditions on Nutrien phosphate mine permit renewal 2023-03-28

Update 2023-04-13: More materials: Hamilton County Planning Commission on Nutrien phosphate mine permit renewal 2023-03-28.

Update 2023-04-12: The County Commission meeting will be April 18th.

The Nutrien Phosphate Mine in Hamilton County, Florida, is up for renewal by the Hamilton Board of County Commissioners on Tuesday, April 28 18, 2023, at 6 PM. There will be a Public Hearing. Since time to speak will be limited, best to send written comments in advance.

The renewal request has already been reviewed by the Planning and Zoning Board (PNZ), on March 28, 2023. PNZ recommends renewal with some conditions.

Private landowners, a number of whose property is inside the mine boundary, object that some of Nutrien’s plans for disposal of waste such as clay will adversely affect those landowners’ businesses as well as wildlife and waters.

Dennis J. Price, P.G., of Hamilton County filed a page of questions.

Bienville Outdoors filed a a request to find other options for settling areas.

Maybe you would like to comment on effects of this mine on the Suwannee River, Swift Creek, the Floridan Aquifer, or public health.

PFAS forever chemicals are in everything –WUFT 2023-02-14

“This stuff is in everything,” said Suwannee Riverkeeper John Quarterman.

In the Withlacoochee River, in fish in the Alapaha River, maybe in your house. Georgia, Florida, and U.S. EPA should do something about it.

A new study by the Environmental Working Group, an activist group focused on research, revealed that eating a single freshwater fish is equal to drinking water with high PFAS levels for a month.

PFAS in fish in Alapaha River 2023-01-17

Largemouth bass caught in the Alapaha River at Statenville Boat Ramp had high concentrations of PFAS forever chemicals.

EWG summarizes the risk:

Eating just one PFAS-contaminated freshwater fish per month could be the equivalent of drinking a glass of water with very high levels of PFOS or other forever chemicals.

What does this map show?

From coast to coast, and in almost every state in the U.S., high levels of the “forever chemicals” known as PFAS contaminate freshwater fish. The potential harm is not limited to fish, but the pollution poses health risks to communities that catch and eat the fish.

Forever chemical residue can even be in your house lot 2022-11-27

That house you bought may come with forever chemicals, per- and polyfluoroalkyl substances (PFAS), which can harm human (and wildlife) health in many ways.

Florida permits shipping sewage sludge from south Florida to north Florida for agricultural fertilizer. It’s not clear how prevalent the same practice is in Georgia. But from fields it can wash into waterways, and subdivisions may be built on fields that had sludge applied.

At the end of Joy Road in Fairfield, a steep dead-end road climbs a hillside to a scattering of homes with distant mountain views and some of the higher concentrations of per- and polyfluoroalkyl substances (PFAS) the state has found to date in groundwater. The neighbors here live under what one resident, Nathan Saunders, called the “cloud of an unknown future,” fearing how PFAS exposure may erode their health.

Abstract

While research and regulatory attention to per- and polyfluoroalkyl substances (PFAS) has increased exponentially in recent years, data are uneven and incomplete about the scale, scope, and severity of PFAS releases and resulting contamination in the United States. This paper argues that in the absence of high-quality testing data, PFAS contamination can be presumed around three types of facilities: (1) fluorinated aqueous film-forming foam (AFFF) discharge sites, (2) certain industrial facilities, and (3) sites related to PFAS-containing waste. While data are incomplete on all three types of presumptive PFAS contamination sites, we integrate available geocoded, nationwide data sets into a single map of presumptive contamination sites in the United States, identifying 57,412 sites of presumptive PFAS contamination: 49,145 industrial facilities, 4,255 wastewater treatment plants, 3,493 current or former military sites, and 519 major airports. This conceptual approach allows governments, industries, and communities to rapidly and systematically identify potential exposure sources.
