Clean, pure water — in sufficient amounts — is one of the most important foundations for optimal health.
Unfortunately, most tap water is far from pure, containing a vast array of disinfection byproducts, fluoride, radiation, heavy metals, agricultural runoff, pharmaceutical drugs and perfluorooctanoic acid (PFOA), a chemical used in the production of Teflon and flame retardants.1
And that's the short list. What's worse, more than half of the 300-plus chemicals detected in U.S. drinking water are not even regulated.2
Each year, red flags over toxic drinking water are raised across the U.S., with reasons varying from location to location. The poisoning of Flint, Michigan, brought much-needed attention to the problem in the U.S., while also exposing the political inertia and outright lies that allow these things to happen.
Olympic Games Highlight Brazil's Water Pollution Problem
In Brazil, the Summer Olympic Games have brought renewed attention to that nation's horrendous water pollution problem.3,4
According to reports, 30 percent of the sewage lines in Rio de Janeiro are exposed, allowing raw sewage to flow openly through the streets, and Guanabara Bay, where sailing competitions will be held, is severely contaminated with fecal matter.
Only half of the city's sewage is ever treated before spilling into waterways. But Brazil certainly is not alone. Water pollution is a significant problem around the world, including the United States. Deteriorating infrastructure only adds to an already challenging problem.
Safe Drinking Water Is Becoming More Difficult to Obtain
According to a recent study, contamination of water supplies around the globe has increased the cost of water treatment by 50 percent in some areas, making it increasingly difficult to provide safe drinking water for all residents.
According to the researchers, two major culprits contributing to the contamination and subsequent price hikes are farms operating in areas that supply water to surrounding cities, and large numbers of people living on and around underground watersheds. As reported by Reuters:5
"Nearly 90 percent of the world's urban watersheds face some level of degradation from agricultural chemicals and increased sediment, making water treatment more expensive, the study said ...
When someone upstream decides to expand agriculture or build more houses it will have a cost (on water treatment) which is not accounted for in the market place,' said McDonald, lead scientist at The Nature Conservatory, an environmental group."
The answer is better land-use management that addresses fertilizer runoff. Dramatic reduction in fertilizer use is also recommended. These remedies are equally costly, but at least they provide a more long-lasting solution.
In some areas, farmers are trying new conservation methods to ward off toxic runoff and protect water quality. Strategies include the construction of artificial wetlands and underground "bioreactors" hooked up to drainage systems to capture nutrients.6
Others have started using cover crops and no-till methods to slow fertilizer and pesticide runoff. The Mississippi River Basin Healthy Watersheds Initiative alone spends $30 million a year to curb agricultural pollution in its high-priority watersheds.
According to one study, it would cost as much as $2.7 billion a year to shrink the dead zone in the Gulf, created by agricultural pollution washing down the Mississippi river.
Lakes and Rivers Across US Are Severely Polluted
While some water contamination is invisible, some is clearly evident. There's no mistaking the raw sewage flow and trash-filled beaches of Rio de Janeiro, for example.
Algae blooms are another sign that agricultural runoff has contaminated a body of water, the nitrogen feeding microorganisms that explode in numbers, turning the water thick and bright red, neon green or muddy brown, with a stench to match.
As the microorganisms extract oxygen from the water, fish and other water organisms suffocate and die in large numbers. The bacteria are also hazardous to anyone coming into contact with the water.
Questions have also been raised about the potential hazards of eating fruits and vegetables irrigated with algae-infested water. As reported by The Washington Post:7
"Utah Lake, a freshwater lake that covers some 150 square miles — one of the largest lakes in the Western states — has been drenched in cyanobacteria, also known as blue-green algae.
The bacterial cell counts reached the tens of millions per milliliter, according to the Salt Lake Tribune. Two years prior, a cyanobacteria bloom that was toxic enough to kill two dogs was far less concentrated, numbering in the hundreds of thousands of cells per milliliter."
Ohio's Lake Erie is another troubled hotspot. Not only is this large freshwater reserve plagued by algae blooms, chemical contamination is so severe the lake has actually caught on fire several times.8 Other severely affected lakes in Ohio include Buckeye Lake and Grand Lake St. Marys.9
Four Florida Counties Declare State of Emergency Over Algae Blooms
This summer, toxic algae is also overwhelming Florida, causing four counties to declare a state of emergency. In the Palm Beach Post video above, a manatee can be seen swimming through the thick green algae bloom covering a canal in Stuart, Florida, on June 29, 2016.
The algae covering Florida's canals and beaches originate from Lake Okeechobee, the largest freshwater lake in Florida, which receives agricultural runoff both from the cattle farms on its north side and the sugar cane fields along its south border.
Contaminated water then flows toward the east and west coasts via the Caloosahatchee River and the St. Lucie Canal.
Staying Safe at the Beach
Algae are not the only hazard lurking in local swimming holes and beaches, though. Unlike algae, which you can clearly see, other dangerous bacteria can also contaminate water without anyone suspecting it.
In July, a 50-year-old man who spent a Sunday afternoon swimming at a Galveston, Texas, beach became infected with Vibrio vulnificus bacteria. By the time he got to the emergency room four days later, the doctors informed him they would need to amputate his leg or he would likely die from the infection.10
So what can you do to minimize the risks to yourself and your family when visiting lakes and beaches this summer? Steve Fleischli, water program director for the Natural Resources Defense Council (NRDC), offers the following suggestions:11
✓ Check your state and local health department website for any water quality alerts. You can also check the Swim Guide,12 which provides water quality reports for 7,000 beaches in the U.S. and Canada. They even have an app you can download to your smart phone. Whether there's a current advisory or not, avoid beaches that have a history of water quality problems.
✓ When you get to the beach, search for any water advisory postings.
✓ In urban areas, avoid entering the water after a heavy rain. Wait at least one day; ideally two or three days.
✓ Stay clear of areas near pipes, ditches or culverts. Also avoid creeks that run out into the ocean.
✓ Inland lagoons tend to be high-risk due to the lack of water movement. If an area smells or you notice slime, leave.
✓ Do not enter the water if you have any open cuts or sores. Also avoid dunking your head, as this will allow water to enter your eyes, nose or mouth.
✓ When fishing, thoroughly wash and disinfect skin punctures and scratches. Avoid touching the bait and bait bucket with your bare hands.
✓ Should you develop any signs or symptoms of an infection following a trip to the beach, such as redness, fever, vomiting, diarrhea or abdominal pain, see a doctor.
Think Water Pollution Is Bad? Just Wait Until the Aquifers Are Drained
According to the Environmental Protection Agency (EPA), U.S. states with high congregation of concentrated animal feeding operations (CAFOs) report 20 to 30 serious water quality problems each year.13 But that's not all. CAFOs and large monocrop farms are also depleting aquifers of valuable drinking water.
We're using up groundwater much faster than it can be replenished. Agriculture is a major contributor to this problem, using 70 percent of the world's fresh water — a volume that could be reduced by implementing sustainable and regenerative farming methods that improve the soil's ability to retain water and prevent runoff. As reported by Mashable last year:14
"Humanity is rapidly depleting a third of the world's largest groundwater aquifers, with the top three most stressed groundwater basins in the political hotspots of the Middle East, the border region between India and Pakistan, and the Murzuk-Djado Basin in northern Africa. Making matters worse, researchers say in a pair of new studies,15 we don't know how much water is left in these massive aquifers."
Water-intensive energy production, such as fracking operations, are also using up valuable freshwater supplies. According to James Famiglietti, Ph.D., a senior water scientist at NASA's Jet Propulsion Laboratory, the majority of our global groundwater "[is] past sustainability tipping points," which means we're on our way toward running out of freshwater worldwide.
And once the freshwater aquifers are drained, that's when the real crisis will set in, likely launching "water wars" and social unrest across the globe.16,17
Deteriorating Infrastructure Puts Your Health at Grave Risk
Adding to these ever-growing conundrums is a lack of investment in infrastructure. Old water pipes can leach lead and other toxic materials, leading to catastrophe. The poisoning that occurred in Flint, Michigan, is but one such example. In August 2015, Virginia Tech scientists led by Marc Edwards18 discovered Flint's tap water was contaminated with, in some cases, astronomically high levels of lead.
They also found a number of other toxins, including high levels of trihalomethanes19 — carcinogenic byproducts from water treatment — and dangerous bacteria such as E.coli and Legionella, the latter of which is suspected of causing an outbreak of Legionnaires' disease.20 Illinois also battled an outbreak of Legionnaire's last year, courtesy of contaminated drinking water.21
Fifty-three residents of the Veterans Home in Quincy — a 129-year-old facility — were sickened and 12 died, which led to the implementation of a $5 million water treatment plant and new delivery system. Still, a month after the reconstruction, two more veterans contracted the disease. Authorities are currently working on identifying the source of the new outbreak.
Edwards also blew the whistle on lead-contaminated water in Washington, D.C. back in 2003. As in Flint, some of the lead levels in the water were high enough to be classified as hazardous waste. Yet in both instances, the EPA kept the contamination problems under wraps.
Lead Contamination Appear to be Widespread in the US
Lead contamination may be far more widespread in the U.S. than previously realized, as municipalities have dragged their feet when it comes to replacing old water pipes. For instance, 8.5 percent of children in Pennsylvania have elevated lead levels, as do 6.7 percent in parts of New York State and 20 percent in Detroit.22
In Baltimore, schools have relied on bottled water for years due to elevated lead levels in the tap water. According to a recent investigation, at least 350 schools and day care centers across the U.S. test above the EPA's action level for lead content in water. 23,24 In the U.S. as a whole, more than half a million children between the ages of 1 and 5 suffer from lead poisoning. As noted in a recent Pittsburg Post-Gazette article:25
"Lead causes a multitude of cognitive deficits, from attention problems and learning disorders to disruptive behaviors, impulsivity and increased aggression. Lead is most detrimental to children because their brains are still developing — in fact they absorb [four] to [five] times as much ingested lead as adults from a given source, according to the World Health Organization.
There is no safe level of lead, according to the Centers for Disease Control and Prevention, and damage is irreversible. Not all is understood on its impact, but one thing is clear — the best treatment is prevention and abatement."
Water Safety Questioned in Massachusetts
Corrosive groundwater speeds up and increases the release of toxic metals from old water pipes. This problem was recently highlighted in a report by the Boston Globe, which noted that 90 percent of the groundwater in Massachusetts may be corrosive enough to cause the leaching of toxic metals from household pipes. Residents drawing water from private wells are at greatest risk. Signs you may have a corrosion problem include:
• Blue-green stains in your sink
• Metallic-tasting water
• Small plumbing leaks
Industrial Farms Are Among the Worst Polluters on the Planet
It's a painful irony that agriculture has become one of the worst polluters on the planet, contaminating soil, air and water with toxic pollutants as par for the course of food production. According to a report26 by Environment America, Tyson Foods Inc. is the worst polluter of U.S. waterways, releasing 104.4 million pounds of toxic pollutants into waterways between 2010 and 2014, second only to a steel manufacturing company.
In third place, we have the U.S. Department of Defense, followed by Cargill and another steel manufacturer. Of the top 15 polluters on this list, six are food companies, commingling with some of the largest chemical producers in the world, including DuPont and BASF.
There are answers. Old pipes can be replaced, thereby addressing lead contamination, but in order to address water contamination as a whole, not to mention the depletion of freshwater aquifers, we must prevent contaminants from entering the water in the first place and reduce water consumption.
This is the only way to adequately address declining water quality and quantity, and this would require significant changes to entire industries. What we need is sufficient will — personal, corporate and political — to implement the needed changes.
How You Can Protect Your Health and Promote Healthy Change
In the meantime, you'd be wise to take precautions to protect your health as best you can, which includes evaluating the safety of your water and making sure your water is properly filtered. You can find more information about water filtration in my previous article, Lead-Contaminated Water Becoming Increasingly Prevalent.
You can also push for positive change by purchasing foods from farmers who have implemented regenerative practices. Remember, each time you buy food, you're voting for a system. Either you're promoting the status quo, which is destroying our air, soil and water, or you're furthering a cleaner more sustainable system. En masse, we can have a great impact on how foods are grown and raised. If you live in the U.S., the following organizations can help you locate organically-grown and non-CAFO foods:
