Environmental Working Group

I highly recommend visiting the EWG site to view their tap water data base. It makes it easier to interpret some the data and possible harmful effects found in the water quality reports above. Also it shows the best filtering method for each substance or chemical. Just enter your zip to begin!

Chlorine vs. Chlorimine

Either Chlorine or Chlorimine will be added to your water to ensure your water stays disinfected as it travels through miles of pipe to reach your faucet.

Chlorine was the original and most common method of disinfection used today. Its effective and low cost. Chlorine is volatile and can escape from water as it travels through water mains. This reduces it’s residual, making the water more susceptible to microbial growth. Also, it doesn’t perform well in mixed company.  A high percentage of dirt or germs in the original water source will react with chlorine to produce chemicals called disinfection by-products. Some of these by-products, specifically trihalomethanes (THMs), were found to be carcinogenic after a lifetime of exposure.

Chlorimine is chlorine with ammonia added. Chloramine is less volatile than chlorine so it stays in the water longer. This ensures all areas of the water distribution network are properly disinfected. It also has lower levels of disinfection byproducts, which is why water systems are making more use of it. According to the Environmental Protection Agency, chloramine provides better protection against bacterial regrowth in water systems with large storage tanks and dead-end water mains. Since chloramine treated water is more corrosive than chlorine treated water, the level of pipe corrosion inhibitor needs to be increased when a municipality switches over to chloramine. Otherwise lead can leach from solder in copper pipes or from lead pipes themselves. When used with dialysis equipment or aquariums it must be removed from the water.

While chlorine and chloramine are not considered to be harmful they are primarily responsible for tap waters bad taste and smell. Also, chlorimine treated water in a glass will take up to a week to dissipate vs. a couple days with chlorine. Most basic carbon filters can easily remove chlorine. However, chlorimine requires more contact time with carbon or the use of catalytic carbon to remove.

With a reverse osmosis filtration system with sufficient carbon you can remove both. Since it has already arrived at your home or office, you no longer need it or have to drink it!
