Trihalomethane concentrations in surface water are usually higher than in ground sources (Villanueva et al.
Nevertheless, the formation of chlorinated byproducts such as
trihalomethanes (THMs) and haloacetic acids (HAAs) is related to reactions between chlorine and natural organic matter (NOM) [4,5].
Distribution and determinants of
trihalomethane concentrations in indoor swimming pools.
Blood and breath analyses as biological indicators of exposure to
trihalomethanes in indoor swimming pools.
Woolcott, "
Trihalomethanes in public water supplies and adverse birth outcomes, " Epidemiology, vol.
Mazzarella held a news conference to discuss efforts to bring the city into compliance with state regulations concerning the levels of
trihalomethanes in the water supply.
Residents were recently mailed letters about the level of
trihalomethanes in its drinking water.
Trihalomethanes (THMs) are compounds derived from methane that incorporate three halogenated atoms.
Influence of exposure assessment methods on risk estimates in an epidemiologic study of total
trihalomethane exposure and spontaneous abortion.
Despite low filtration rates and long empty-bed contact times (EBCTs), conventional slow sand filters have achieved limited removals of organic precursor material, with dissolved organic carbon (DOC) and
trihalomethane formation potential (THMFP) reductions averaging less than 15 to 25 percent.
During that time, the
trihalomethane levels in the distribution system were above the regulatory limit.
Our second article specifically addresses the issue of
trihalomethane. Without discussing all the details, I can say that our process significantly reduces
trihalomethane levels.
