A One-Year Survey of Halogenated Disinfection By-Products
Conclusions
In the present study, which examined DBP variations as a function of treatment practice, season and sampling location, the overall picture that emerged was that no single sampling event captured the complete image of the behaviour of DBPs in drinking water.
DBP concentrations were observed to fluctuate as a function of water treatment practice (and variations therein), age of the water and temperature of the water. DBP concentrations were usually higher in the summer than in the winter for all treatment processes.
With chloramine treatment DBP concentrations did not, in general, increase significantly with distance (time) in the distribution system. With chlorine treatment THM concentrations increased with distance (time) in the distribution system and maximum values were found at the sampling point furthest from the treatment plant.
The behaviour of the other DBPs was far more complex. Their concentrations showed an initial increase with distance (time) in the distribution system, but depending on the season and age of the water the concentrations could either increase or decrease at greater distances (time) in the distribution system.
Of particular importance from a regulatory viewpoint is that no single site or time of year could be selected to provide simultaneous maximum values for the three major DBPs (TCM, DCAA and TCAA). The development of a sound sampling strategy to assess consumer exposure to DBPs will require more in depth studies to provide a greater understanding of the DBP behaviour within distribution systems.

Water For Life
Water For Life is dedicated to renting equipment for filtering and purifying water of chlorine, heavy metals, lead, bacteria, cysts, parasites, THM, trihalomethane, and viruses so that you experience water that is crystal clear, refreshing and tastes clean. We have self filling water bottles for your office and we provide specialty purified water for industries such as printers, welding shops and aquariums.
Our self filling bottled water is for those of you who don't have the time to lift bottled water, store bottle water, or deal with empty bottled water bottles. Our bottled water never leaves the top of your water cooler. Instead we connect our purified or filtered water right to the bottled water and it fills up when you take a cup full.
We have researched the effects of chlorine, and chlorine by products in the Victoria water system and alone they constitute enough reason to filter and purify our drinking water, shower, and bath water.
In the process of changing Victoria City water into great tasting, crystal clear drinking water we use carbon / charcoal filters, poly spun filters, reverse osmosis membranes, and KDF media to filter various impurities from your tap water so it is pure and healthy.
Please look at our research page and breaking news page to discover for yourself what is in tap water and what can be done to protect yourself from ingesting disinfection agents in Victoria City water.
Ask about whole house filter systems. The only way to end chlorine entering your body is for you and your family is to install a whole house, point of entry filtered water system.
We rent reveres osmosis and carbon filter systems for your home, office and industry. Our rental water purification systems include full maintenance including the cost of filters for one standard rental price.
With the Water For Life under sink water purification system, tap water first flows through three pre filters to remove dirt, rust, sediment and chlorine.
If the cooler or holding tank is less than full, the water continues on to the next stage of the process.
The reverse osmosis membrane, will separate contaminants from the molecules of water. The contaminants are then washed down the drain and the purified water then moves on to your water cooler or pure water reservoir.
We also rent whole house water filters that filter the water for your whole house or business. Whole house big blue water filters create a rain water like shower for you whole family. Look for combined rates for whole house water filters and reverse osmosis water filters on our price list page. For higher ranking with Google and Yahoo use shop in Victoria BC Canada.
