New Research Highlights Hidden Disinfection Byproducts in Tap Water That May Be Harmful to Human Health

New Research Highlights Hidden Disinfection Byproducts in Tap Water That May Be Harmful to Human Health

For decades, municipal water treatment has been one of the greatest public health achievements in modern history. Disinfectants like chlorine and chloramine are added to tap water to eliminate harmful bacteria and viruses, helping prevent serious waterborne diseases.

But recent research suggests that the chemistry of treated water may be more complex than many homeowners realize.

A new study from researchers at Stevens Institute of Technology found that when disinfectants react with naturally occurring organic matter in water, they can form what are known as disinfection byproducts (DBPs). 

This emerging research highlights an important point: even properly treated tap water contains a mix of minerals, disinfectant residuals, and chemical reactions that vary from home to home.

And that’s only part of the picture.

In Edmonton, many homes also deal with hard water — high levels of calcium and magnesium that can lead to scale buildup, reduced appliance efficiency, dry skin, and increased energy costs. 

So while water may be disinfected for safety, it can still impact your home’s plumbing, your appliances, and even the way it tastes and feels.

A Two-Tier Solution For Resolving Water Problems in Edmonton

Resolving common home water issues often requires a two-tier solution that addresses both mineral content and chemical contaminants. 

Water softener systems tackle hard water by removing calcium and magnesium, preventing scale buildup, protecting appliances, and improving daily comfort, while reverse osmosis (RO) filtration systems focus on the water you drink, reducing chlorine, disinfection byproducts, heavy metals, and other impurities.

Tier 1 – Using Water Softeners to Improve Water Quality 

Even treated municipal water can contain chemical byproducts from disinfectants interacting with natural minerals in water. While these levels are safe to drink, hard water minerals like calcium and magnesium can influence water quality, contributing to scale buildup, appliance wear, and minor chemical interactions in your home plumbing.

Scale from hard water can reduce water heater efficiency by up to 24% as per the Water Research Quality Foundation. Calcium and magnesium can interact with disinfectant residues, ultimately worsening the effects of DBPs already present in tap water.

For Edmonton homes, this makes water softening an important step. The city’s water supply, sourced from rivers like the North Saskatchewan, naturally carries higher levels of calcium and magnesium, making hard water an even greater concern for local homes.

Water softeners use an ion exchange process to remove hardness minerals, replacing them with sodium or potassium ions. This prevents scale from forming and improves overall water flow and efficiency throughout your home. 

Many users report softer skin, smoother hair, and fewer irritations after switching to softened water, while it also reduces the amount of soap, shampoo, and cleaning products needed in laundry and bathrooms.

In essence, a water softener system is not just an investment in your health but an upgrade in your lifestyle as well.

Tier 2 – Using Reverse Osmosis for Cleaner Water Supply

While water softeners address hard water, reverse osmosis (RO) systems focus on the water you drink and cook with, providing an additional layer of protection that traditional filtration systems often cannot. 

Unlike standard filters, which may remove chlorine or sediment, RO systems use a semi-permeable membrane to reduce disinfection byproducts, heavy metals, dissolved salts, and other microscopic impurities. This leads to cleaner and safer drinking water. 

While softeners mainly address the hardness minerals in water, RO systems focus on removing DPBs, filtering out impurities as small as 0.001 microns. They complement softeners by delivering purified water at faucets, ice makers, and drinking points, while softeners protect pipes, appliances, and overall household water quality. 

Combined together, a water softener and an RO system form a comprehensive two-tier solution, addressing both mineral-related issues and chemical contaminants at the source.
