Drinking water supplies are becoming a big issue in the United States, as water shortages and the rise of plastic pollution are forcing many Americans to seek bottled water instead.

According to a survey by the Pew Research Center released Thursday, more than one-third of Americans say they would like to drink water that is treated with a water filter.

While that number may seem small to some, it’s a large number when it comes to a country that relies heavily on the tap for nearly half its water.

“That’s a very high percentage of Americans, and we know that water filters are a very effective water filter,” said Peter J. Shumway, a professor of environmental and natural resources at George Mason University.

He noted that Americans are generally more willing to pay for water filters if the filter is certified by the government and the company providing the water has the required certification.

But for many Americans, the filters are still not up to par, according to the survey.

Only 35 percent of Americans said they were willing to buy a filter that can filter more than 1,000 gallons of water a day.

And a whopping 56 percent said they would not be willing to spend money on a filter if the company did not offer a guarantee that the filter would be able to filter up to 1,500 gallons of drinking water a week.

The poll also found that just 29 percent of respondents said they had been “completely” informed of the dangers of plastic contamination.

The findings are consistent with previous studies that have shown Americans are more likely to use plastic than their European counterparts, and are more willing than others to pay a premium for the convenience of plastic.

The Pew study also found Americans are significantly more likely than Europeans to say they have no idea about the risks of plastic to drinking water.

Just 30 percent of U.S. adults said they did not know the risks posed by plastic.

But even though Americans are not aware of the plastic pollution, they are not being warned.

According the survey, 37 percent of adults said that they had never heard of plastic, while 28 percent had heard of it in a past job interview or a family member.

And more than a third said they knew about the problem from someone else in the family.

And the majority of Americans (62 percent) have never seen a plastic bag.

This poll comes just a few weeks after the Department of Health and Human Services issued a warning about the dangers posed by the growing plastic pollution in the U.K., Germany, France and other countries.

According a recent study, a study of nearly 7,000 water samples found that more than 40 percent of the samples had levels of plastic that were unsafe for drinking or using.

And the study also showed that a whopping 57 percent of people said they thought plastic was a threat to the environment, compared to 33 percent who thought it was a problem for humans.
