:198 Ozone Water Purification

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet environment.

1:5:10:198 EcoTip: Ozone has some uses for killing bacteria as a part of water purification. This method has become popular for spas and swimming pools permitting a reduced amount of chlorine to be used. When used for drinking water purification, it should be combined with other types of filtration and purification to address contaminants that ozone doesn’t reduce.

Ozone has been used for helping to achieve low bacteria levels in spas, hot tubs, wells, pools and water purification units. One way of generating ozone uses UV light which was discussed yesterday in :197.

:197 UV Water Purification

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet environment.

1:5:10:197 EcoTip: Ultra Violet Light (UV) has some uses for killing bacteria as a part of water purification. Think of it as an alternative to chlorination. Unlike chlorine it has no residual effect.

UV has been used for helping to achieve low bacteria levels in spas, hot tubs, wells and water purification units. The UV light needs to be shielded so it is concentrated on the water and avoids causing damage to people’s eyes and skin. UV is rendered useless when “shadowing” occurs. In order for it to be effective the bacteria must be exposed to the UV light. Sediment, hardness, minerals, iron, manganese or turbidity will also make the UV system ineffective because the bacteria is shielded from the UV.

This information was paraphrased from the third edition (released in May 2008 ) of Prescriptions for a Healthy House: A Practical Guide for Architects, Builders & Homeowners which I wrote with architect Paula Baker-LaPorte and physician Erica Elliott.

:089 Know Your Reps

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet.

1:5:10:089 Tip:If you have been following this blog, you can probably tell that I am a firm believer in the need for environmental infrastructure. You personally can reduce, reuse, recycle and that simply won’t be enough. Each of us can make a difference, but political action is just as important. Get to know your local, state & federal representatives and not just what they say they will do, but find out what they are actually doing and have done in the past.

Additional Information

Congressional representatives can be searched at: https://forms.house.gov/wyr/welcome.shtml

U.S. Senate representatives at: http://www.senate.gov/

State representatives can usually be tracked down by searching Google for: <your state>senate and <your state> assembly

They are also commonly listed in the government listing section of your phone directory.
