Concentration of trihalomethanes (THM) and precursors in drinking water within distribution networks. Water chlorination is the disinfection method most widely used, having however the disadvantage of producing trihalomethanes (THM) as secondary compounds, which are included in the list of priority ...
The Safe Drinking Water Act and its Amendments (SDWAA) may potentially limit each individual species of THM compounds in water distribution systems since the health risks associated with these species are not alike. A new approach to characterize and model the kinetics of THM species using nonlinea...
The water treated by lime softening had significantly higher levels of THMs in comparison to the water treated by reverse osmosis. With the aging of reverse osmosis membranes (after 5 years), the THM levels exhibited similar levels in both distribution systems. The THM concentrations at the cul ...
Test results obtained by Rachel Connor over a four-year period showed high levels of potentially cancer-causing chemical trihalomethane (THM). We're drinking it now but medical advice is it may take decades to see the effects; MORE RESIDENTS FEAR FOR WATER NEAR WINDFARM; Cancer-causing chemic...

This paper describes trihalomethane reduction in an Istanbul drinking water plant. The total THM levels (TTHM) could be controlled by decreasing the post-chlorination doses. After the commencement of the pre-ozonation process, pre-chlorination was terminated and a sudden drop of THM values in ...
The DBPs that have been quantified in drinking water are generally present at low to mid 渭g/l levels or below. Approximately 50% of the total organic halide (TOX) formed during the chlorination of drinking water and more than 50% of the assimilable organic carbon (AOC) formed during ...
low pH chlorinated finished drinking water, this study suggests that it is important for utilities to encourage consumers to flush drinking water through the plumbing in their home to ensure that THM concentrations reflect the levels in the distribution system rather than elevated levels in the home...
However, it generated higher levels of THM than chloramination. THM generation was directly related to chlorine residual and contact time. The results suggested that breakpoint chlorination could effectively inactivate total coliform while meeting the drinking water standard.Chloramination with the use of...
