Which country has the most hard water?

A new study has found the United States has the second-highest level of hard water in the world, behind only Japan, according to a new report.

The report, released Monday by the Pew Research Center, comes as lawmakers in at least nine states have called for new limits on the amount of chlorine in drinking water supplies in an attempt to keep water safe from the deadly water crisis in Flint, Michigan, and the subsequent water contamination crisis in California.

The study found the U.S. has the highest rate of water pollution from chlorine in the developed world.

The report found that of the 20 countries in the report, six of them have at least a 50 percent concentration of chlorine, while China has the lowest concentration of water.

The U.K., which has been hit hard by the water crisis, has not had a problem with chlorine in its drinking water.

But the U,S.

and Europe are far apart in their efforts to limit the amount and types of chlorine found in the water supplies, with the U.’s total levels at more than 1,000 parts per billion (ppb) and Europe at just under 200 ppm.

The Pew report said the U is far behind China in the use of chlorine but has a higher concentration of disinfectants than the other countries in its study.

In terms of the amount, the U., which is in the middle of a massive drought, has more chlorine than any other country.

The new report said countries that have a high concentration of chloramine and chloramine-containing compounds are often found in sub-Saharan Africa, where most people live.

It said China, which has the world’s largest population of Chinese, has the third-highest concentration of these compounds.

The data on the water used in the U.—more than three-quarters of the total amount of water—is not available for the U of A. That data is available from the National Center for Environmental Information, but the Pew report did not make any reference to that.

The lack of data on how the U’s water is treated is particularly important, according the report.

As it has been for years, the Pew researchers looked at the number of days it took for the chlorine to wash out, how much chlorine was used, and how much the water was treated.

The researchers found that about two-thirds of the water in cities and towns in the study was treated before it reached the consumers, and that about 90 percent of that was treated with disinfectants and disinfectants-rich water, the report said.

The remaining 5 percent was treated less than half as much.

The authors of the report wrote that the data showed that “a significant proportion of chloramines and chloramines-rich wastewater” is being stored in the ground.

They said that this “can lead to a significant reduction in the amount the disinfectant industry uses to clean the water supply and to the level of disinfectant that is being used.”

The study also found that the U and other countries have been putting chlorine into the drinking water for more than 30 years, but that the concentration of the chemical in the drinking waters is now rising.

The researchers found a slight decrease in the concentration in the United Kingdom, with only about a tenth of the U.-level level.

The scientists said the “growing concentration of high-level chloramines in drinking-water sources” raises concerns about the health effects of chlorine exposure in humans.

The U. of A.’s drinking water, they said, could contain “significantly elevated” levels of high levels of chlorines and chloraminates, including “potentially harmful” effects on human health.

The problem is compounded by the fact that some of the most common types of chlorine-containing chemicals are now being used, the researchers said.

The group also found the use in the countries of chlorinated water was also growing.

“While it is likely that chlorine use is not the only cause of the increasing levels of contaminants in drinking systems, it is clear that the increase in use has increased contamination,” they said.
