Summary
Barium, a naturally occurring element, has sparked concern in NYC’s water supply. Understanding its origins and health implications is crucial for residents.
- The Nature of Barium: A chemical element with potential health risks.
- How Does Barium End up in Drinking Water?: Both natural processes and human activities contribute.
- Current Regulations on Barium Levels: Governed by federal and state guidelines, but local implementation varies.
However, there is more recent public talk of the quality of the water we drink, particularly in big cities such as New York City. But one compound that’s been in the crosshairs of scientists and concerned citizens alike is barium. But for all its eerie moniker, barium is a chemical element that occurs naturally in the Earth’s crust, and that leaks into our water supplies by accident and by industrial process. New Yorkers turn on their taps each morning, and the question of whether or not their water has barium floats in the air.
The Nature of Barium: What You Need to Know
Barium is a chemical element, the chemical symbol is Ba, and the atomic number 56. It’s an alkaline earth metal and is commonly used in drilling fluids for oil and gas wells, as well as in the production of rubber and glass. The element doesn’t come up much in the scientific literature, but when it’s in water to drink, its presence can be highly consequential.
There’s naturally barium present in some rocks and soil, but it’s the concentrations that get out of hand. Barium, if consumed in excess, can lead to gastrointestinal issues, blood pressure and other diseases. The only way to get at the larger problem, therefore, is to learn its causes and health impacts.
How Does Barium End up in Drinking Water?
Barium enters a water body in a number of ways. Natural causes can be Barium containing rocks and minerals dissolve into the water (natural processes, such as rainfall, can also contribute). There can also be anthropogenic (human-caused) reasons, for example, in industrial discharges and agricultural runoff with fertilisers and pesticides.
New York City is notably the only city where water comes from both nature and man. It has more people, older infrastructure and so Barium contamination is more likely. These include the contamination of old pipes and warehousing with Barium which only compounds the problem.
Current Regulations on Barium Levels in Drinking Water
The Environmental Protection Agency (EPA) regulates the amount of Barium allowed in a drinking water supply under the Safe Drinking Water Act. The legal limit is 2 mg/L. Over this point, there is a strict penalty for public safety.
In New York, there is even a state regulation in the state, which matches roughly the federal guidelines. But these rules aren’t enforced the same way in NYC as they are in other cities. Local treatment plants, for instance, may have different technologies or processes to track and eliminate Barium — all of which impacts the quality of water at your faucet.
Barium Monitoring Methods
Conventional barium detection in labs is typically performed by spectroscopy with expensive apparatus and technical expertise. These methods are true, but they take time and money.
But the good news is that new, faster ways of detecting it have been developed thanks to technological advances. Some of these include:
Disposable test kits with instant results.
High-tech sensors inserted in water storage tanks.
Android apps attached to home filters.
These technology developments have made it possible to test more often, and have the public monitoring their own water quality.
What Do Test Results Reveal?
The Barium tests for NYC water have always varied a little bit but were often within the safe range of the EPA. Perhaps this is a signal that current monitoring and treatment programmes work very well in controlling Barium levels.
But when it comes to New York City’s Barium levels in comparison with national and international norms, you have to consider a host of external variables, such as geographic distribution and density. The city could do fine in some studies, but the higher probability due to its special conditions cannot be discounted.
Treatment Options: Removing Barium from Water Supply
Beurrage, exchange of ions and so on are chemical methods of barium removal. These are chemicals added to the water which stick to Barium and are easier to filter out. This type of procedure is used in big water treatment plants, and is generally considered extremely effective.
Other than chemical disinfection, activated carbon or reverse osmosis filtration systems can be used, particularly at home. Some of these can even be mounted on taps for an added measure of protection for skeptical customers.
Public Opinion and Awareness
Incredibly, people don’t know about Barium in NYC water. While state and federal laws do exist, there’s been very little media reporting on the matter, so most New Yorkers are unaware.
Grassroots campaigns and grassroots action, however, are beginning to stir the pot. Increasingly, public forums, social media campaigns and educational sessions focus on water quality monitoring such as Barium levels.
Legal Ramifications and Public Accountability
Thousands of water quality lawsuits have been brought in the past, but rarely one involving Barium. These court cases are also a wake-up call to governments to tighten laws and offer more public services.
The management of water quality doesn’t just rest with government bodies. There are also judicial avenues for complainers or for collective action. This is a dynamic context where accountability from the state and public engagement are necessary.
