Summary
New Yorkers should understand the role of chlorine in their water treatment process:
- Chlorine is vital for disinfecting water and preventing waterborne diseases.
- NYC has used chlorine effectively for decades, evolving its methods over time.
- Chlorination enhances water quality, taste, and safety, providing cost-effective treatment.
Our drinking water is something that any citizen in a big city like New York should care deeply about, and particularly about whether it is good or bad. Millions of people depend on the public water supply daily, so knowing how it is treated becomes even more important. One of the main components used for this is chlorine.
Historical Background of Organochlorines
Chlorine is an extremely effective disinfectant and the main purpose of chlorine in water treatment is to remove harmful microorganisms that cause many diseases. Since its introduction into water treatment more than 100 years ago, chlorine has reduced, if not eradicated, waterborne disease such as cholera, typhoid and dysentery. The magic of chlorine is that it gets on the wall of bad bacteria and kills them.
What’s more, chlorine prevents the growth of pathogenic microbes in the water flowing from the treatment plant to our faucets. By keeping a residual chlorine level, the water doesn’t get contaminated. It’s a bit like an armoured vehicle that constantly monitors the water, to make sure that what gets into our taps isn’t tainted by virulent germs.
The Evolution of Chlorine Use in NYC
New York City — a huge city with a lot of different people — has never been able to have good water. There were multiple water-borne disease epidemics in the first decades of the 20th century, and water treatment was essential. Enter chlorine. When it was added to NYC’s water treatment system, it changed everything. In time, the cases of illness caused by tainted water began to decline, and chlorine was an effective disinfectant.
But as the decades have passed, NYC’s chlorination process and equipment has gotten more sophisticated. With technological advancements and scientific research, we can now get better chlorine levels and better water treatment. It’s proof that NYC doesn’t want the city to be without good water.
Benefits of Chlorinating NYC's Water Supply
- Protection Against Waterborne Diseases: As mentioned earlier, chlorine effectively combats harmful pathogens, reducing the risk of diseases like cholera and typhoid.
- Enhanced Quality and Taste: Contrary to popular belief, optimal chlorine levels can enhance the overall taste of water by removing certain contaminants.
- Cost-effective Treatment: Chlorination is not only effective but also economical, ensuring large-scale water treatment without exorbitant costs.
Chlorine’s role isn’t just restricted to disinfection. Its addition ensures that the water remains protected throughout its journey from the treatment facility to our homes. The residual chlorine acts as a safeguard, preventing any subsequent contamination.
Potential Health Concerns and Myths
Another complaint is the taste and smell of chlorine in the tap water. Although for some people the smell can be too strong, it’s usually a harbinger that the water is safe. But, of course, taste or smell don’t always tell you about the chlorine levels. Water quality, minerals and compounds all can affect the taste and smell of the water.
For many years, there were rumours that chlorine had health risks in drinking water. The chlorine concentrations used to disinfect water have always been well researched and are safe for human consumption. These are usually the chemicals that are left behind after chlorine combines with living materials. NYC knows this and there are techniques used to reduce these by-products and keep the water within safe and acceptable ranges.
The Science Behind Chlorine Treatment
Chlorine is disinfecting because it disintegrates the cell walls of bacteria that kill us, turning them harmless. Chlorine reacts with water to create hypochlorous acid and hydrochloric acid when mixed with water. But particularly the acid hypochlorous is very effective in removing bacteria and viruses.
An alternative or companion of chlorine is sometimes used instead, called chloramine. Chloramine is a combination of chlorine and ammonia, and its disinfectant action lasts longer than chlorine alone. This allows for water to stay in place over time, which is great for big networks such as NYC.
Alternatives to Chlorine in Water Treatment
Chlorine has a long history of efficacy, but there are several other options in the works for water treatment. An obvious choice is ozone, an oxidant that can kill bacteria. There’s also ultraviolet (UV) disinfection — UV light kills or switches off undesirable creatures.
But each technique has pros and cons. For example, ozone and UV are powerful disinfectants but don’t give the residual protection chlorine does. That’s because the water, after a treatment, is easily contaminated. That residual protection, among other things, is what makes chlorine the go-to for a large percentage of public water systems.
How NYC Monitors and Regulates Chlorine Levels
NYC also is very serious about having clean water. It’s been implemented in such a way that the city monitors it on a strict basis so that the chlorine levels are kept at an optimal and safe level. At several locations along the water network, test are done every day. This is so that harmful bacteria are effectively killed, and the chlorine remains in acceptable levels.
Not only does NYC have daily checkpoints, it has regulations in place to control the chlorine levels. The city complies with rules of organizations such as the Environmental Protection Agency (EPA). These regulations are based on a lot of research and are meant to provide you with the safest and best water supply.
Tips for New Yorkers: Handling Chlorinated Tap Water at Home
If you don’t like chlorine’s smell or taste, there are home remedies for that. Simple methods include:
Drinking from a Pitcher: Placing tap water in a pitcher for hours will dissolve chlorine, making it taste better.
Chlorine taste & odor filter: There are numerous water filters available in the market which could eliminate chlorine smell and taste.
Water Boiling: Boiling water for a few minutes removes chlorine.
Be reminded, these methods could decrease the chlorine in the water and the antimicrobial action. So if you store treated water, drink it within a day or two so it doesn’t go bad.
