Does boiling water remove trihalomethanes?

Trihalomethane concentrations were reduced in both chloraminated (74-98\%) and chlorinated (64-98\%) water upon boiling. Most of the remaining DBPs (e.g. haloketones, chloral hydrate, haloacetonitriles) were removed by at least 90\% after 1 min of boiling in both samples.

How do you remove trihalomethane from drinking water?

The easiest way to reduce or eliminate THMs in drinking water is to use a water pitcher with a carbon filter, install a tap-mounted carbon filter, or to use bottled water. When using a filter, check to verify that it is certified to remove THMs and follow replacement instructions recommended by the manufacturer.

Does trihalomethane cause cancer?

Due to the variations of the THMs compositions, it is observed that higher concentrations of total THMs do not necessarily lead to higher cancer risks.

What is the suspected health risk of trihalomethanes THMs in drinking water?

The byproducts, including THMs in water, can cause cancer and are suspected of causing reproductive problems. Research from the National Institutes of Health shows that people are exposed to THMs by drinking water, and by using it to shower, bathe, or wash dishes by hand.

Why is trihalomethanes a concern?

Trihalomethanes (THMs) are the result of a reaction between the chlorine used for disinfecting tap water and natural organic matter in the water. At elevated levels, THMs have been associated with negative health effects such as cancer and adverse reproductive outcomes.

What filters remove trihalomethanes?

Both Aquasana and Amway water filters are proven to be effective at removing more than 99\% of THMs from water. Kenmore and Culligan water filters also filter out large percentages of these substances.

What is a safe level of trihalomethanes?

Based on this review, the guideline for total trihalomethanes in drinking water is established at a maximum acceptable concentration of 0.1 mg/L.

What is the MCL for trihalomethanes?

(1) Subpart L – RAA compliance. (i) Compliance dates….40 CFR § 141.64 – Maximum contaminant levels for disinfection byproducts.

Disinfection byproduct	MCL (mg/L)
Total trihalomethanes (TTHM)	0.080

Are trihalomethanes bad?

Does bottled water contain trihalomethanes?

Various trihalomethanes were detected in four brands of bottled water, including Sam’s Choice and Acadia, at two to three times greater levels than the bottled water industry’s voluntary standard of 10 ppb (IBWA 2008).

How THM is formed?

THMs are formed in drinking-water primarily as a result of chlorination of organic matter present in raw water supplies. The rate and degree of THM formation increase as a function of the chlorine and humic acid concentration, temperature, pH, and bromide ion concentration (Stevens et al., 1976; Amy et al., 1987).
