Background: Trihalomethanes (THMs) are widespread disinfection by-products (DBPs) in drinking water, and long-term exposure has been consistently associated with increased bladder cancer risk. Objective: We assessed THM levels water the European Union as a marker of DBP estimated attributable burden cancer. Methods: collected recent annual mean municipal 28 countries (EU28) from routine monitoring records. linear exposure–response function for average residential by pooling data studies...
While natural organic matter (NOM) surrogates are established in disinfection byproduct (DBP) research, their use fractionation studies is rare. To understand how relate to drinking waters, a range of NOM were fractionated with XAD resins. Their trihalomethane (THM), haloacetic acid (HAA), haloacetaldehyde, haloacetonitrile, and haloketone formations after chlorination recorded. compounds higher log KOW values behaved as hydrophobic acids, the more hydrophilic did not clearly correlate KOW....
The HIWATE (Health Impacts of long-term exposure to disinfection byproducts in drinking WATEr) project was a systematic analysis that combined the epidemiology on adverse pregnancy outcomes and other health effects with low levels water (DBPs) European Union. present study focused relationship occurrence concentration DBPs vitro mammalian cell toxicity. Eleven samples were collected from five countries. Each sampling location corresponded an epidemiological for program. Over 90 identified;...
Formation of harmful disinfection by-products (DBPs), which trihalomethanes (THMs) and haloacetic acids (HAAs) are the major groups, can be controlled by removal natural organic matter (NOM) before disinfection. In literature, precursors is variable, even with same treatment. The treatment DBP NOM was examined intention outlining precursor strategies for various water types. Freundlich adsorption parameters hydroxyl rate constants were collated from literature to link treatability activated...
Biodegradation is a potentially important loss process for haloacetic acids (HAAs), class of chlorination byproducts, in water treatment and distribution systems, but little known about the organisms involved (i.e., identity, substrate range, biodegradation kinetics). In this research, 10 biomass samples tap water, system biofilms, prechlorinated granular activated carbon filters) from nine drinking systems were used to inoculate total thirty enrichment cultures fed monochloroacetic acid...
Ultraviolet light-emitting diodes (UV-LEDs) have recently emerged as a viable technology for water disinfection. However, the performance of in full-scale drinking-water treatment systems remains poorly characterised. Furthermore, current UV disinfection standards and protocols been developed specifically conventional mercury so do not necessarily provide an accurate indication UV-LED performance. Hence, this study aimed to test hypothesis that reactor can match Cryptosporidium inactivation...

The characterisation and treatment of natural organic matter are becoming more important to the water utilities in UK around world. This paper looks at relationship between bulk fractionated material performance conventional processes.
Haloacetic acids are a class of disinfection byproducts formed during the chlorination and chloramination drinking water that have been linked to several human health risks. In this study, we isolated numerous strains haloacetic acid-degrading Afipia spp. from tap water, wall distribution pipe, granular activated carbon filter treating prechlorinated water. These harbored two phylogenetically distinct groups alpha-halocarboxylic acid dehalogenase genes clustered with previously detected only...
Problems arise at water treatment works due to the reaction of natural organic matter with chlorine produce disinfection by-products (DBP). Trihalomethanes (THMs) are main DBP regulated in various countries. The UK THM standard is 100 μg L –1 while USA it 80 . At certain times year efficiency conventional processes compromised seasonal increases concentration (NOM). During these periods generally increase coagulant dose but this subsequently volume potable sludge generated. Advanced...

Seasonal periods of high rainfall have been shown to cause elevated natural organic matter (NOM) loadings at treatment works. These levels lead difficulties in removing sufficient NOM meet trihalomethane standards, and hence better alternative treatments are required. Here the removal was investigated by conventional coagulation using both bulk fractionated NOM. Initial experiments showed that over 70% hydrophobic hydrophilic acid fractions achieved works, while only 16% nonacid fraction...
