Haloacetic Acids in Drinking Water: What You Need to Know
Monday, January 20, 2025
Haloacetic acids are formed when disinfectants such as chlorine are added to tap water
Haloacetic acids (HAAs) are a group of chemical byproducts formed
when disinfectants like chlorine interact with organic and inorganic
matter in water. These acids are commonly found in treated drinking
water in the Philippines due to the widespread use of chlorine as a
disinfectant in public water systems. The five major types of haloacetic
acids include monochloroacetic acid, dichloroacetic acid,
trichloroacetic acid, monobromoacetic acid, and dibromoacetic acid.
While disinfection is critical for eliminating pathogens, the presence
of HAAs in drinking water has raised concerns about their potential
impacts on human health.
Prolonged exposure to elevated levels of HAAs has been linked to a
variety of health risks. Studies suggest that chronic ingestion of water
containing high concentrations of HAAs may increase the risk of
developing cancer, particularly of the bladder and colon. Some HAAs,
like dichloroacetic acid and trichloroacetic acid, are classified as
probable or possible human carcinogens based on laboratory studies
involving animals. In addition, there is evidence that HAAs may disrupt
liver function and impact reproductive and developmental health,
although further research is needed to fully understand these effects in
humans.
The Role of Water Filtration in Removing Haloacetic Acids
Haloacetic acids (HAAs), harmful byproducts of water disinfection
processes, can pose risks to human health when consumed in high
concentrations over time. Advanced water filtration systems, such as
PureH2O, have proven effective in reducing HAAs in drinking water,
ensuring safer consumption. Filtration technologies like activated
carbon filters, reverse osmosis, and granular activated carbon (GAC)
systems are particularly efficient in targeting and removing these
contaminants. These systems work by trapping the chemical compounds
within their filtration media or by forcing water through semipermeable
membranes, which separate impurities, including HAAs, from the water
supply.
Good water filtration not only reduces HAAs but also helps minimize
exposure to other disinfection byproducts (DBPs) and contaminants. Using
point-of-use filters, such as those attached to faucets or pitchers,
can complement municipal water treatment and provide an extra layer of
protection. Additionally, maintaining proper filtration system care,
such as timely replacement of filter cartridges, ensures consistent
removal efficiency. For households reliant on private water systems,
investing in high-quality filtration systems is especially crucial to
safeguard against HAAs and promote overall water quality.
