Important Note about Bacterial Contamination of Portland Water

Most of the residents of the Town of Portland are aware that the town water system in our town has tested positive in two tests for the presence of Total Coliform Bacteria which is a bacteria that often is considered an indicator of the presence of more dangerous bacteria that could possibly pose a health risk for those who consume it. The most common forms of bacteria found in water systems (private and public) are Coliform and E-Coli, but other notable forms are Cryptosporidium and Giardia, both of which are also dangerous and cannot be disinfected by Chlorine which is the usual way that bacteria is killed or prevented in municipal water systems. (NOTE: Cryptosporidium and Giardia are NOT present in Portland’s water system so please do not be alarmed) This town-wide Coliform contamination will almost certainly result in larger amounts of Chlorine injected into the system which may or may not completely disinfect the system and the piping and fixtures in your home.

There is a product available that is designed to kill all forms of bacteria that are typical in this type of contamination. Ultra-violet light (UV) has been used for many years to do just that. An easy explanation about how UV works from Trojan Technologies is that as the water passes by the UV bulb, the UV rays “penetrate into the bacteria and viruses and destroy their ability to function and reproduce. The process is simple but effective and our systems destroy 99.99% of harmful microorganisms without adding any chemicals or changing your water’s taste or odor”.

A big advantage to installing a UV system in place of bottled water or in addition to bottled water is that although many people drink bottled water, it gets very expensive to cook with and use it for other things you would normally use tap water for. Along with the expense it can be quite inconvenient to use bottled water to wash vegetables and fruit, and other food items that require soaking or washing in cold water.

We install UV systems, and we strongly recommend it to give our customers in Portland and anywhere water contamination is possible, the peace of mind that your water can be free from bacterial contamination. The basic unit from TrojanUV that we are currently installing is the TrojanUVMax-D which is rated for up to 14 gallons per minute of water running through it. This unit is reliable and requires very little maintenance, if there are no other impurities in your water (i.e. hardness, iron, sediment, etc.) this should operate without any service need other than a change of the light bulb once a year.

Please read some additional notes:

  • Although a UV system is very effective in killing contaminated water entering your home, it will not prevent contamination due to “Cross-connections” within your home. Some common forms of household cross connections are: hose connections without vacuum breaker backflow preventers, certain types of toilet fill valves, cross connections of well system to the city system, hoses left in outdoor pools or fountains, water irrigation systems without proper backflow valves, etc. We can certainly visit your home and inspect your plumbing system for such cross connections.
  • We also recommend having your water in your home tested before and after installation of UV systems. If bacteria is already present in the municipal water system before installing the UV system, it may not clear up bacteria in the piping after it and the system may need to be chlorinated to immediately disinfect.
