SAINT LEO, FL – After hearing about contaminated public drinking water supplies in Flint, Mich., and a handful of other communities, more than half of respondents in a national poll say they are very or somewhat concerned about the safety of their own hometown’s water supply, the Saint Leo University Polling Institute ( found.

The new national survey also reveals that more than three-quarters of those polled were at least somewhat aware of the contamination that has occurred in various states and communities and was reported nationally in news media. The online poll contacted 1,001 adults nationally from June 10 through June 16. A parallel sample of 500 adults was polled during the same time period in Florida, the home state of Saint Leo University.

Results were markedly similar in the national and state surveys, revealing widespread unease about water supplies. Saint Leo science faculty commenters said that because of the provisions of the federal Safe Drinking Water Act (first passed in 1974 with subsequent updates) to protect drinking water and its public sources, for the most part, the United States provides safe drinking water from the tap—a benefit that many places in the world do not enjoy. Still, recent cases have raised fears, and the public appears to have serious questions about water resources.

The polling institute’s June survey included questions to gauge public perceptions of water quality, of the reliability of the infrastructure, and attitudes about regulation, among other issues.

The survey started asking about confidence in water supplies with these questions:

Water safety has been in the news lately.  Contaminants such as lead has been found in public water supplies in Flint, Michigan; Sebring, Ohio; Washington, D.C.; Durham, North Carolina; Columbia, South Carolina, and many other communities. Prior to receiving this survey, how    aware would you say you were about the water contamination issues?  Would you say…


Awareness level indicated U.S. –   % Florida – %
Very aware 37.5% 34.4%
Somewhat aware 41.4% 44.6%
Combined: very aware and somewhat aware  78.8% 79.0%
Somewhat unaware 10.0% 9.8%
Not at all aware 6.6% 7.0%
Combined: Somewhat unaware and not at all aware 16.6% 16.8%
Unsure 4.6% 4.2%


 How concerned would say you are about the safety of water in your hometown…

Level of concern U.S. – % Florida –  %
Very concerned 27.2% 28.2%
Somewhat concerned 31.7% 30.6%
Combined: Very and somewhat concerned 58.9% 58.8%
Somewhat unconcerned 17.8% 26.8%
Not at all concerned 21.1% 16.2%
Combined: somewhat and not at all concerned 39.9% 43.0%
Unsure 2.3% 3.2%


“Because of the egregious actions of a few elected officials in Flint, hundreds of thousands of people were affected,” commented Dr. Leo Ondrovic, associate professor at Saint Leo, where he is a member of the science faculty. “So it is no surprise that a majority of survey respondents are concerned about water quality issues. But the truth is that domestic water supplies in the U.S. are among the safest sources of clean water. The Safe Drinking Water Act requires the Environmental Protection Agency to set standards for drinking water, and empowers them to enforce water quality.” The EPA, the 50 states, tribal governments, and water systems are supposed to work together to ensure standards are met for more than 170,000 public systems.

Bottled Water Not a Sure Fix

What may seem to consumers as an obvious alternative to tap water is not necessarily a solution, cautioned Dr. Laura Altfeld, another Saint Leo scientist and associate professor. She worries that some people think bottled water is safer than tap water in the United States—but people should not make this assumption, she said. Bottled water is regulated less frequently, and not uniformly, she noted. Oversight involves the Food Drug Administration, and not the EPA, she added.

“Bottled water also presents an additional cost to the consumer, may consist merely of tap water anyway—and therefore be subject to any hazards consumers want to avoid by purchasing bottled water—and can present new hazards, such as chemical contaminants that may leach from the bottle and into the water,” the biologist continued.

Underlying Water Resource Questions

The polling institute survey probed people’s attitudes about rights to supplies of water and about resource management. The survey presented respondents with a number of statements, and asked them to indicate whether they strongly agreed, somewhat agreed, somewhat disagreed, or strongly disagreed.

Respondents revealed agreement—strongly agreed or somewhat agreed—to the following statements. They are listed here in descending order (of the entire U.S. base).

  Statement U.S. – % agreeing, strongly & somewhat Florida – % percentage agreeing, strongly & somewhat
Clean, consumable water is a human right 90.4% 93.0%
I’m willing to pay more in taxes to ensure safe, consumable water supplies 72.2% 71.6%
We face an impending water crisis in the United States 64.7% 62.2%
We have increased water conservation measures over the past year such as reduced watering 62.5% 63.8%
The federal government should force states to share their supplies of water with other states 52.7% 56.6%
Our household has reduced reliance on the public water supply out of fear for safety 31.2% 33.4%


Altfeld said that it makes sense to her that most people consider water a right: “None of us can survive without water.” In 2010, the United Nations decided to make an explicit declaration of the human right to access to safe drinking water, noting water has become a more important worldwide issue.

Within the last year, Ondrovic noted, Pope Francis stressed (using italics) in his written teaching on care of the environment (Laudato Sí) that “access to safe drinkable water is a basic and universal human right.”  Ondrovic wondered if the pontiff’s influence can also be credited to some degree for the broad agreement shown among the Saint Leo poll respondents.

With that said, more than six in 10 Americans see an impending water crisis. Notably, residents of rainy Florida registered concern at levels as high as the national sample about water resources.

Altfeld attributed that to manmade stresses on the peninsula. “Even though Florida receives abundant freshwater in the form of rainfall relative to some other states,” Altfeld said, “it is not immune to problems associated with freshwater quality and quantity limitation. We Floridians put enormous pressure on our aquifer as consequences of intense development, agriculture, and industry. We also have difficulty preserving natural landscapes, particularly freshwater wetlands, which act, in part, to recharge our aquifer.”

And visible stresses on freshwater drinking water sources are visible in other parts of the country, as well. For instance, Ondrovic described the consequences pollution is having for water suppliers in the Midwest, where algae blooms have appeared.  “The toxic algae contaminating lakes in Ohio can be linked to water pollution issues,” Ondrovic said. “Algae blooms are usually promoted by pollution in the form of nutrient runoff from agricultural and commercial activities. The algae is not only very difficult to physically remove, but it is also very difficult to deal with the toxins.”

And in another case, he added, “Water contamination in North Carolina was found to be related to a leaking coal ash pit. Both are examples of why our water sources are at risk and growing scarce.”

Ondrovic added that he found it “shocking” that more people were willing to pay increased taxes to ensure safe consumable water than reported using conservation measures. It could not be determined from the survey results though, to what degree conservation measures, such as reduced lawn watering, are voluntary, given that it is common for communities to enforce mandatory reductions.

Altfeld said that overall, she found hope in the survey results “in that they reveal substantial public awareness and concerns over water as an invaluable, and nonnegotiable, resource. I hope we will all remember to continue to ask good questions of and demand transparency from our resources managers. In addition, we need to be willing, and to remain willing, to make changes in how we think about and use water to contribute to vigilant stewardship of this critical resource.”
