Why is there massive amounts of lead in the Flint River?
Why is it that you are congenitally incapable of understand and presenting facts correctly.
The Flint River does not contain massive amounts of lead. Period.
The lead came from the residents HOMES because they had lead pipes and or soldier. The flint river water contained chlorides and chlorates, (from road salt) which prevented orthophosphate from controlling corrosion. This was compounded by the slightly lower ph of the flint water increasing corrosion.
go over in the corner by your dish and lay down you fucking imbecile.

Fortunately, once again your crap is easy to defeat.
Let me quote YOUR OWN LINK:
quote:
The main contributor of the Flint River’s high chloride concentrations, according to Edwards, is road salt combined with the natural salt content of the river and the additional chloride the city uses to clean the water. “In US cities where ice is a problem in winter, the average road salt use per person per year is 135 pounds,” he says. “It’s incredible. In many northeastern cities because of road salt use, salt content in rivers has doubled in the last 20 years.”
Now, regarding your allegation about lead: Using your own source, again:
quote:
Edwards found that chloride concentrations in the city’s drinking water had soared from 11.4 mg/l to 92 mg/l after switching to the Flint River. He said high chloride levels corrode plumbing infrastructure, causing lead particles to separate from the pipe and leach into the water.
Using your own source here is a quote supporting what I said - the lead was due to increased corrosion:
quote:
Edwards wrote that after the switch to the Flint River water, the corrosiveness level as measured by the Larson Iron Corrosion Index rose from “0.54 (low corrosion) to 2.3 (very high corrosion) and the chloride to sulfate mass ratio (CSMR) index for lead corrosion increased from 0.45 (low corrosion) to 1.6 (very high corrosion)”.
Since you're fond of Wiki - here's a quote: https://en.wikipedia.org/wiki/Flint_River_(Michigan)
quote:
Tests showed after water left Flint's treatment plant, it was lead free, but by the time it reached the tap, it sometimes had elevated levels of lead. This happened because the Flint River water was more corrosive to lead pipes than the previously used water source, Lake Huron.
Now, as to your second quote. That was quite a bit of deceptive work, there. The EPA required GM to do clean-up based on concentrations of pollutants in the silt (not the water).
Your figures, which you attempt to pass off as showing the Flint River water supplied to the residents was contaminated with lead
a). Were from 2007, prior to clean-up
b). Were near the GM outfalls (Ie., where gm was dumping into the river
c). In contrast, the flint river water intake was near mott lake - upstream by miles.
In other words - you gave false information.
But lets analyze even your crap information. The concentration of lead in the silt is expressed in milligrams per kilogram.
In otherwords 10e-3/10e3. We are talking about parts per million at the point.
If you then take the fact that in that area the river is 150 feet wide, and more than a dozen feet deep with a flow rate of billions of gallons an hour - you get the actual factual conclusion that lead in the flint water supply is not a factor. Which is of course, true, since I posted the flint water treatment plant water quality report which says the same damn thing.
Here's a few more FACTS for you.
quote:
History shows that as early as 1964, the U.S. Geological Survey noted high levels of chloride in the river, which often comes from road salt. But it said that didn't preclude it as a source of drinking water, even though a series of reports had noted that Flint River water was always more challenging to treat than Lake Huron water.
The river supplied Flint's drinking water for 50 years and improvements to the treatment plant had allowed it to be used as a backup supply since the 1970s. When Flint connected to Detroit's system in 1967, most of the concerns about the river water involved quantity, not quality: Experts worried the river couldn't supply enough water to meet growing demand, especially in drought conditions.
quote:
"We have such a fantastic river and it's taking a beating," said Rebecca Fedewa, director of the Flint River Watershed Coalition, a nonprofit environmental group....
Improvements have even come in the most industrialized part of the river near downtown Flint as industry has shut down and some sites have been cleaned up.
"It's about 2 miles out of 142, but that's the impression people have of the whole river," Fedewa said. "Now we have people who think that if they get near the water they are going to get chemical burns. They think their kayaks are going to melt."
Much of the river winds through woods and farms.
"There are stretches of that river where you can kayak for two or three hours without ever crossing a road," she said.
The Flint water plant draws from the river south of Mott Lake and well upstream from the most polluted parts of the river. From 1917 through 1967, the river provided drinking water to the city.
"The intake for the water was above the city," said David White, a Flint native and president of the Genesee County Historical Society...
Farther upstream from Mott Lake is the Holloway Reservoir, filled with river water that residents use for swimming, boating and fishing.
"There is fantastic fishing throughout the watershed," Fedewa said. "We have smallmouth bass, walleye. People have actually caught steelhead in downtown Flint."
Fedewa said people eat the fish out of the river. The DNR issues the same warnings for the river as it does for all fish in Michigan, which can contain mercury from air pollution.
As for quote:
Uh, you have went full fucking retard, the pipes are not painted with lead.
And I dont give a fuck what slobbering factless nutsucker link you posted, orthophosphates were not used.
No, the pipes aren't painted in lead, moron - they ARE lead. Flint has 60,000 homes that either HAVE lead pipes, or pipes joined with lead soldier. As I said about a dozen times so far.
As for orthophosphates not being used. Also as I said - for more than half a dozen posts. Orthophosphates - the industry standard in preventing corrosion WEREN'T used because testing revealed they did not work. The river chemistry meant that flint river chemistry was 317% more corrosive. Addition of orthophosphate, which has its own health concerns reduced that to 298%. Which meant it was not an effective treatment for the problem.
So, in summary:
You are wrong about flint river water being the source of the lead.
You are wrong about GM being the cause of the problem.
You deliberately posted false and inflammatory information in the hopes that people wouldn't catch your deception.
The source of the problem was not the republican appointed administrator - it was the karegondi water authority not correctly treating the water, which had been successfully done from 1917 to 1967. That water authority which was appointed entirely by democrats.
