(THMs), the most common of the DBPs, were first discovered in the 1970s (Bellar and Lichtenberg 1974; Rook 1974), and hundreds of DBP species have been identified since.
Tena, Fibre selection base on an overall analytical feature comparison for the solid-phase microextraction of trihalomethanes
from drinking water, Journal of Chromatography A: 1139(1), 27-35 (2007).
Description of trihalomethane
levels in three UK water suppliers.
Natural organic matter and formation of trihalomethanes
in two water treatment processes.
The Drinking Water Inspectorate's latest annual report states: "Dwr Cymru Welsh Water consider that the adverse weather conditions (torrential rainfall) in 2007 caused a general deterioration in raw water quality, resulting in higher levels of organic matter which challenged the performance of their treatment works giving rise to more coliform and trihalomethane
Researchers at the University of Memphis evaluate chemical analyzers and associated analytical methods for on-line monitoring of trihalomethane
(THM) and haloacetic acid (HAA) concentrations in drinking water.
While imposed for good reason, the rule also will increase the number of trihalomethane
(THM) and haloacetic acid (HAA5) compounds in drinking water samples that need to be tested.
Amy GL, Chadik PA, Chowdhury ZK (1987a) Developing models for predicting trihalomethane
formation potential kinetics.
In addition, the plant's discharge had trihalomethane
levels exceeding limits set by the National Pollutant Discharge Elimination System permit program.
The conversion to monochloramine provided higher concentrations of total chlorine (which includes both free chlorine and monochloramine) and lower concentrations of trihalomethane
compounds, the principal disinfection byproducts in treated water entering the distribution system (Table 1).
The injected water's trihalomethane
level is well below the federal limit for drinking water, but it is above that of well water - which typically contains zero, officials say.
Minimal disinfection by-products (DBP) formation at high biocidal rate -- 30%-50% reduction in trihalomethane
(THM) formation compared to traditional chlorination methods.
In Kenora, efforts are under way to reduce trihalomethane
(THM) in the system.
It also highlighted poor compliance with guidance on toxic trihalomethane
For example, EPA's regulation of trihalomethane
in drinking water has an estimated cost per normalized life saved of $600,000, whereas the regulation of Atrazine/alachlor in drinking water has an estimated cost per normalized life saved of $274 billion.
