What you need to know about water-related chemicals


— As more people in the state turn to the water supply, more of them are encountering a toxic chemical called ammonium nitrate, a potentially deadly compound.

In a series of recent stories, Politico has learned about more than 30 chemicals that are used in the water treatment industry.

Some are safe to use and some are not.

We’ve also learned that some of the chemicals are being phased out in Wisconsin.

In the months since the Wisconsin Supreme Court ruled in favor of the state’s water-treatment industry, the state has added more than 200 chemicals, including nitrate and ammonia.

And the state is now adding more than 1,000 chemicals in the near future.

It’s a trend that is only expected to continue.

The Environmental Protection Agency has announced that more than 700 new chemicals are planned to be added to its hazardous chemicals list within the next two years.

But it doesn’t specify which chemicals the agency is looking at.

A spokeswoman said the agency has “been working closely with the Wisconsin Department of Health and Environmental Quality to develop the list.”

A spokesman for the state Department of Water Resources told Politico in an email that the department has taken a step toward updating its hazardous list.

He said the department is working with the EPA and the Wisconsin Chemical Council to develop an updated list.

In recent weeks, we’ve learned about ammonium-nitrate.

The state has removed it from its water-based treatment systems.

But we don’t know what the EPA’s list of chemicals is.

And that list is being phased-out in Wisconsin, too.

That’s because some of those chemicals are coming out of the wastewater treatment plants, where they are used to remove contaminants from the water.

The Wisconsin Environmental Protection Act prohibits the state from using chemicals in wastewater treatment unless they are approved by the EPA.

But the EPA does not have the authority to require that companies stop using them.

So what chemicals do the EPA require companies to use?

And why are some of them coming out?

We asked a dozen companies that manufacture and sell ammonium, nitrate or ammonia products to tell us about the chemicals they use and why.

Companies say that the chemicals come from both the raw sewage and the treated water, which they treat with a mix of chlorine, iodine, and other chemicals.

These chemicals are mixed with water, added to the wastewater and then treated with a chemical called sodium nitrate to remove the nitrates.

The EPA and some environmental groups have said that sodium nitrates are a dangerous substance, which is why they are removed from the wastewater.

The chemical industry argues that sodium is safer because it’s produced in small amounts and doesn’t have the corrosive properties of ammonium.

In fact, there are some studies showing that sodium, when combined with other chemicals, can neutralize nitrates and other pollutants that could harm humans.

“Sodium nitrate is a very, very safe product,” said Kevin Cone, president of the Wisconsin State Council of Manufacturers, an industry group.

“The EPA has said that it’s a safe product.”

The EPA is considering banning sodium nitrites in its hazardous chemical list.

In the meantime, the agency continues to monitor the situation.

But if the EPA finds a chemical in Wisconsin’s wastewater that could pose a health risk, the company must remove it from the system and replace it with another one that has a lower toxicity.

There are a few companies that are currently using sodium nitrite, including the manufacturer of the water-treated chemicals.

The company declined to provide the name of the company or the number of chemicals it uses, citing federal regulations.

But in a recent interview with Politico, the owner of the plant said he has more than 300 chemicals that come from the treated wastewater.

It appears that many of the new chemicals being used in Wisconsin are sodium nitro compounds, which are a byproduct of a process known as sodium nitrification.

The process takes sodium nitric acid and water to separate it into sodium nitride and sodium nitrosulphite.

These compounds are combined with nitrates to form nitrate nitrite.

The resulting nitrate produces ammonia.

Nitrate nitrate compounds are used primarily in industrial and residential water treatment plants.

It’s unclear whether the ammonium and nitrite are being added to water systems to remove nitrate.

In one recent case, the EPA ruled that the ammoniodide used in a Wisconsin wastewater treatment plant must be removed from its system.

But this ruling doesn’t apply to a small group of water-purification plants.

These plants produce a product called sodium-nitrite.

The Milwaukee Journal Sentinel first reported that ammonium Nitrate was being added in December 2016 to a sewage treatment plant in northern Wisconsin.

That plant is in the city of Kenosha.

The Journal Sentinel obtained a copy of a March 30, 2016, letter from the EPA to the Kenosas water
