the toxin that shut off toledo’s water? the feds don’t make you test for it.

Doug Keller is a water man in sandarski, Ohio.
He had a hard week.
He runs the small city\'s water treatment plant, which draws drinking water from troubled Lake Erie.
The factory is located 60 miles downstream of Toledo.
What happened to Toledo\'s water?
It\'s good or bad, it\'s bad now-
Usually go to Keller\'s factory.
As a result, Toledo was frightened last weekend when he issued a rare \"no water\" warning for its 500,000 customers.
Toledo\'s water treatment plant absorbs a blue flower.
Green algae, and a worrying high level of algae blue toxin
These things are so powerful that the military has studied the potential of their weapons.
Now the toxin is in Toledo\'s faucet.
Keller hurried to test the drinking water of sandarski.
But he doesn\'t have.
There is no national standard for algae toxins in drinking water. U. S.
The utility does not need to be tested for this.
How common this toxin is in drinking water is a mystery.
Monitoring is voluntary.
Even if the water company is indeed looking for toxins, how and when the tests are carried out opens the door for inconsistent results. The U. S.
S. Environmental Protection Agency has been discussing drafting rules for blue toxins for many years, but has not taken action.
The lack of national standards did not lead to a water crisis in Toledo.
But that makes the problem more complicated.
This makes it harder for people to know if water is really safe for cooking, bathing and drinking.
Algae breeding in Lake Erie and other lakes and reservoirs is expected to deteriorate
Due to the mix of global warming, invasive species and pollution --
This problem is expected to occur more frequently.
Toledo is thought to be a turning point.
\"I bet we will soon have national guidelines for these toxins,\" Jeffrey M said . \"
Renter, program director, Ocean grant College, Ohio.
\"It will be a wise move.
At sandarski, Keller will not wait for the direction.
Hours after Toledo issued a warning early Saturday morning, Keller ordered a test of supply in his city.
He went on testing every day last week.
Keller said: \"The confidence of my customers has been shaken . \" His official title is director of water.
Terrible toxins in blue
Green algae are called algae toxins.
Its goal is the liver, where it can accumulate and clog.
It can cause diarrhea and nausea.
Dogs die after eating flowers in contaminated lakes.
The same is true of cattle and horses.
Human death is rare.
Of the 1996 patients, 130 dialysis patients in Brazil were affected by algae toxins.
At least 50 people were killed. So with no U. S.
Some states have tried to fill regulatory gaps with rules on algae toxins.
Ohio announced its drinking.
Water test strategy in 2011 when people are painfully aware that harmful flowers will be the regular force of summer.
But even under Ohio guidelines, Keller only needs to test Weekly whether sandarski\'s water contains blue toxins and only needs to be tested if it is found to be blooming nearby.
This year, to be on the safe side, Keller began testing sandarsky\'s water every week at the beginning of the year, flowering or not.
He tested Tuesday before the Toledo water crisis. All was clear.
But four days have passed. Keller worried.
Sandusky doesn\'t have the tools to test if his water contains blue toxins.
Detection of toxins is not an easy process, which is one reason why federal regulators are reluctant to release national standards.
Sandusky shipped samples to other utilities.
Usually kai le dou someone
Whoever has free time, his lab staff, his maintenance staff-
Drive to the Elysee Palace, Ohio, about 45 minutes from the hotel.
But earlier last week, the laboratory staff of Eliya were out of town.
So the samples were sent to the town of Oregon outside Toledo.
As with most utilities, Sandusky takes water for testing in two places: after collecting water, it is called \"raw material\", after processing, that is, finished water.
The result will come out in a day.
Tests on Monday showed that plants in sandarski are absorbing water.
Algae toxins 41 per billion. The blue-
Green muck.
But that level is not a concern.
Below the restrictions recommended by the World Health Organization 1.
Drinking water is divided into 0 servings per billion.
Sandusky levels cannot be detected after standard water treatment.
The finished water was clean.
The results of Tuesday\'s survey show:
61 parts per billion in raw water.
However, the water flowing into the faucet is still very clear.
Sandusky also checks water three times a week under a microscope.
A staff member at a processing plant placed a drop on the slide and looked for a black ball of the unique shape of the algae toxin that stuck together.
This is an inaccurate approach, but it gives Keller a better idea of what\'s going on in Lake Erie.
For most water treatment plants, it is not difficult to fight off the surge in algae toxins.
In Sandusky, Keller processes water with alum, which is attached to toxic particles and discarded like heavy objects.
He added powdered activated carbon to absorb any residual toxins.
It seems like a trick.
Keller added that perhaps if the water flowing into the sandsky plant reaches a catastrophic level of 10 per billion for the algae toxin, \"I don\'t know if we can handle this well, \"I don\'t want to try. ”But the blue-
The green algae floating in Lake Erie are not serious.
In fact, it is considered a mild case.
At 2011, the lake is blooming by a worse one.
And there were no accidents in the regional water supply system.
That\'s why Toledo\'s current troubles are so interesting.
Experts are curious about why Toledo can\'t stop toxins from reaching the tap.
Heidi Griesmer, a spokesman for the Ohio Environmental Protection Agency, said the state government was investigating the matter.
Toledo officials did not respond to requests for comment many times.
Wayne Carmichael said something went wrong, he is a retired biology professor at Wright State University in Dayton, has been studying algae toxins for many years, and has worked with the federal government on Toledo\'s water problem.
\"They seem to have missed the bloom,\" Carmichael said . \".
\"They were surprised, I\'m sure.
But like the weather, the flowers in Lake Erie are predictable.
In the summer, the National Oceanic and Atmospheric Administration produced a weekly heat map showing \"harmful algae reproduction\" in Lake Erie \".
A new map came up the day before Toledo released its \"useless\" order.
The water near Toledo was red with anger.
\"They should test every few days so you don\'t miss such an activity,\" Carmichael said . \".
There are also problems with testing.
There are different agreements.
A method was used by Toledo\'s water officials.
The other was used by state officials.
In the first few days of the water crisis, different levels were detected. Some were fine.
Others were shocked.
Very confusing.
Is water safe?
\"Different labs use different processes,\" Griesmer said . \".
As Toledo officials have tried to explain in the city\'s preliminary report on the incident: \"There are conflicting and inconsistent parameters for the sampling and analysis of algae toxins due to harmful algae reproduction. ”The U. S. EPA jumped in.
It worked with Ohio officials to develop a new Standard Test Method for Ohio utilities.
\"So we can know that we have confidence in the results,\" Griesmer said . \".
The proposal was quickly passed on to other water treatment plants in Ohio.
Keller received a copy of him on Tuesday.
Federal officials are considering drinking water rules for algae toxins and other blue toxins. In June, the U. S.
EPA hosted a meeting in Arlington, Va.
, Discuss how to deal with Blue toxins and other water pollutants such as agricultural pesticide ethanol in the next step.
It will take years to join the federal Safe Drinking Water Act.
But at the meeting, EPA officials discussed a new method for detecting toxins.
This may help speed up the process.
\"We need national monitoring,\" said Alan Robertson of the American Water Industry Association.
At the same time, Keller is wary of Sanders water.
He has been running the water plant for 20 years.
More and more challenges.
A few years ago, it was a zebra clam. An invasive species blocked the water inlet.
Then the dead Lake District. Now, it’s blue-green algae.
\"There was never a dull moment,\" he said . \"
He\'s going to buy sandarski\'s own Blue toxin. Testing Machine.
He thinks the problem will last for a long time.
He just got the latest daily test results.
At the moment, the water in Sandusky is clean.
