Although the dangers of radon gas in the home have been well publicized over the last few years, few people think of it coming in through their water supply. The state of Maine is requiring landlords to test for radon by March 1, 2014. (This is in addition to other water testing requirements already in place.)
Radon gas is created when the radioactive mineral radium degrades. Radium leaches from phosphates and other radium bearing rock formations (including granite) into the water. Radon will quickly escape from water as soon as it hits the air, but may linger in the room for minutes to hours. As water is run in the kitchen faucet or as one is taking a shower, the gas separates from the water and is inhaled.
The State of Maine limit for radon is less than 4000 pCi/L for drinking water. Up to 1/3 of all wells in Maine have radon gas over 4000 pCi/L.
A major health concern is the prolonged exposure to radiation. Elevated radioactive intake has been found to cause genetic disorders, birth defects, and many types of cancer. Radon gas may cause lung cancer and the longer you are exposed, the higher your risk. It has been linked to stomach, liver and brain cancer, also. In Maine, 25% of lung cancer deaths have been linked to homes with radon gas in the well water.
If your water is found to contain above the recommended levels of radon, we may recommend installing either a carbon filter or Bubble Up System to treat your water.
Please see section Resetting Backwash Cycle
for resetting the time instructions.
This filter consists of a mineral tank filled with media inside (often referred to as a bed) and a control head. As your water passes through the bed of the filter, the impurities in your water are attracted to the media particles inside the tank. The particles attach to the media inside the tank, removing them from the water before it exits the filter.
Eventually the media inside the tank becomes saturated, so the timer on the head of the system is set to automatically backwash the filter every few days to clean out the media inside the tank.
Carbon filters require very little maintenance but the media bed inside the tank does eventually wear out. The media will need to be replaced every 2-5 years, depending on the level of impurities and amount of water used daily.
If there is a power outage, or after daylight savings, you will need to reset the timer. This is important to reset because you don't want to unknowingly use water during a backwash cycle. Please see section Resetting Backwash Cycle for resetting the time instructions.
