‘Is it safe to drink tap water?’: Ask a doctor

Recent reports of a contaminated water supply in the Dallas-Fort Worth area — leading to residents being warned not to use water from their faucets earlier this week — have sparked general safety concerns.

The city of Grand Prairie, Texas, announced that firefighting foam was detected in the water on Tuesday, then announced on Thursday that the water is safe to drink, per local reports.

Fox News Digital spoke to experts about potential risks with unfiltered tap water.

ASK A DOCTOR: ‘CAN I BE DEHYDRATED EVEN IF I’M NOT THIRSTY?’

Generally speaking, it’s safe to drink tap water, according to Dr. Brynna Connor, a board-certified family medicine physician in Frisco, Texas, and an ambassador for Northwestpharmacy.com — "as long as it’s from a public water system and there aren’t any active boil water advisories issued by local health committees and/or water companies."

"According to the Centers for Disease Control (CDC), the public water system in the United States is one of the safest in the world, ensuring that water in the public systems meets federal standards for safe consumption," Connor told Fox News Digital.

In some cases, however, there could be risks associated with drinking unfiltered tap water, including various illnesses impacting the gastrointestinal system, neurological system and reproductive system, according to Connor.

"Additionally, lead poisoning and hepatitis are potential risks that come with drinking unfiltered tap water, along with nitrate contamination and fluoride exposure," she added. 

Infants, older adults and people with weakened immune systems are particularly susceptible to the potential risks that come with drinking unfiltered tap water, the doctor said.

Jennifer Dunphy, a doctor of public health and co-founder of the WIN Network in Los Angeles, California, agreed that most tap water is regarded as safe to drink, as it is regulated by standards that require harmful chemicals to be limited to a minimum — but that doesn’t mean there’s no risk at all.

"Just because tap water does not cause immediate health issues doesn’t mean there isn’t a concern for long-term health consequences," she told Fox News Digital.

Tap water may contain trace amounts of chemicals like chlorine and arsenic, the doctor warned.

"These chemicals may accumulate in the body over time, and there is conflicting evidence on whether they pose long-term health risks," Dunphy said.

Cherilyn Davis, MD, a physician with Elliston Pediatrics in New York, reiterated that in the U.S., it’s generally safe to drink tap water, but noted that the regulations do not apply to wells that are privately owned.

"If you’re drinking well water, be sure to check with the owner that they’re monitoring for any contaminants beforehand," she advised.

If unfiltered tap water has contaminants in it, drinking it may lead to certain health issues like upset stomach, vomiting, diarrhea and nausea, Davis warned.

Other symptoms may include headaches or even fever.

"If the unfiltered water contains high levels of lead, it can lead to learning problems for children," she said. 

"Chemicals and contaminants may end up in water simply because they’re naturally occurring in the environment, or it could be from the way land is operated on or nearby sewers or wastewater treatment systems that malfunction."

One way to combat potential chemicals is to use a home filtration system.

"There are many affordable filtration systems that can filter out or mitigate the amount of chemicals left in your drinking water," Dunphy said.

When choosing a system, she emphasized the importance of making sure it is proficient at filtering the chemicals of concern.

"For example, only certain filters filter out arsenic, while some specific filtration systems are focused on chlorine," she noted.

Filtration is especially important for those who use well water, the experts agreed.

"If you’re getting your tap water from a private well, it’s important to test the water regularly to ensure it’s safe," Connor advised.

"Well water can easily be contaminated by substances like heavy metals, bacteria, parasites, and pesticides and/or herbicides, or other contaminants, such as plutonium, uranium or radium."

Those who live in an area where the water is known to have high levels of contaminants or have a lead service line should also consider a filtration system, the doctor advised.

"If you don’t want to install an entire filtration system, you can use a faucet-mounted filter, a point-of-use filter or a pitcher filter," she added.

Dr. Joseph Mercola, a board-certified family medicine osteopathic physician in Florida, agrees that using a home filtration system is a "smart move" that can help improve taste and provide "peace of mind."

Filtration is especially important for people with health concerns, those with weakened immune systems and young children, according to the doctor.

"From my understanding, reverse osmosis systems are very effective, removing up to 99% of contaminants," he told Fox News Digital. "If that's not an option, activated carbon filters with ion exchange can also work well." 

Mercola recommends choosing a filter certified by NSF International to ensure that it’s effective. 

Davis noted that while it’s not absolutely necessary to use a filtration system, it can help to further filter out any germs or contaminants.

"Some substances in tap water are good to drink, like fluoride, which keeps your teeth healthy," she noted. 

"Look for filters that eliminate only the unwanted components of the tap water."

It's crucial to be proactive about understanding what's in your water, Mercola emphasized.

"Drinking pure water is vital, as it supports your body's functions and health."

The doctor recommends testing your tap water regularly, which will help you choose the best filter for the contaminants in your area.

Homeowners can also read their local water quality report to better understand what's in their tap water, he advised. 

It’s important to follow local advisories about water safety in emergencies or when traveling to areas with questionable water quality, Mercola added.

Trump accepts largest police union endorsement, blasts Harris as a 'defunder': 'Kamala's crime wave'

The nation’s oldest and largest police organization endorsed Donald Trump Friday, saying there is "zero doubt" they want him in the White House for a second term, while the former president blasted his opponent, Vice President Kamala Harris, as a "defunder" of law enforcement, and vowed to end "Kamala's crime wave" if elected. 

Trump traveled to North Carolina Friday to speak at a meeting of the Fraternal Order of Police and accept their endorsement, calling it an "honor." The organization also endorsed Trump in 2016 and 2020. 

"Public safety and border security will be important issues in the last months of this campaign," FOP National President Patrick Yoes said. "Our members carefully considered the positions of the candidates on the issues and there was no doubt—zero doubt—as to who they want as our President for the next four years: Donald J. Trump."

Yoes said that during Trump’s first term, he "made it clear he supported law enforcement and border security."

"In the summer of 2020, he stood with us when very few would. With his help, we defeated the ‘defund the police’ movement and, finally, we are seeing crime rates decrease," he said. "If we want to maintain these lower crime rates, we must re-elect Donald Trump." 

Yoes said FOP leadership met with Trump—but said a similar meeting was not offered by Vice President Kamala Harris’ campaign.

"As the nation’s oldest and largest law enforcement labor organization, the FOP’s presidential endorsement is one of the most sought-after endorsements by candidates running for the presidency," Yoes said. "The FOP is the number one voice of America’s law enforcement. We have a responsibility to our members, to the 800,000 sworn law enforcement officers in the United States, and to the communities they serve to do our part in determining the direction in which our country will head."

Yoes said Trump, during his first term, "provided our nation with strong, effective leadership." 

"Now that he is seeking election to a second term, we intend to help him win it," Yoes said. 

Trump touted the endorsement Friday afternoon during an event with members of the Fraternal Order of Police. 

"It's an honor to be here. This is a big endorsement for me…It's an honor," Trump said. "I'm thrilled to be back with the incredible heroes and patriots of the Fraternal Order of Police, an incredible group and a group that's highly respected all over the country."

Trump added: "To all of the law enforcement men and women here today, I respect you so much. I admire you, and as your president, I will always back the blue as I did." 

Trump blasted his opponent Vice President Kamala Harris as a "defunder." 

"I back to blue more than any other. I was not a defunder like Kamala. She was a defunder. She was a ten year defunder. When you, when you want to defend for ten years, that's the end of that one," Trump said.

He joked: "I think I could leave right now, and you say there's no way that we're not voting for that guy." 

"I consider you in this room to be America's finest," Trump said. "You're all over the country, all over from the country, all over the place. And, we really appreciate you being here." 

Trump said law enforcement officers just want to "see our country, be safe and prosperous, and we want to love our country."

"We know all about you and the great job that you do. And, the people of this country respect you greatly for it. So I just want to thank you on behalf of everybody," Trump said. 

"Under the Harris regime, 99% of law abiding citizens suffer while criminals run free and our country is plagued into literally third world conditions. In many ways, we're a third world country, but we're going to clean that up real fast," Trump said. "I'm here today to declare that we do not have to live this way. And when I'm President of the United States, we are not going to take it anymore." 

Trump said that there has been a 43% increase in violent crime since the Biden-Harris administration came into power, including a 58% increase in rape and an 89% increase in aggravated assault. 

"And under Comrade Kamala, assaults on police officers are up a minimum of 32% and many of them are not reported. And if they are reported, they're not taken down. And shootings of our police officers are up by over 16%," Trump said. "The day I take office is the day that Kamala's crime wave comes to an end. It's a crime wave in our country. We've never seen anything like it."
