Is There an Effective Well Water Filter?

Bringing well water into your house puts lots of responsibility on the home owner. With the number of contaminants that may be in the water supply it is a necessity to do comprehensive research on well water filters.

The first step before you go out and look at any well water filters is to get a chemical analysis done on your water. This is easily done by taking a water sample down to the nearest certified water testing laboratory in your area. Just by searching on the internet you can find your state certification officer by visiting the U.S. EPA Web site.

If you’re lucky, in some areas your local health department may do the testing for free. Now armed with information you can now make some informed decisions about well water filters.

One of the most common naturally occurring kinds of pollution found in well water were organisms such as viruses, bacteria and other microorganisms. The good news is that these creatures only typically occur after flooding and during the spring runoff. So they are not present in the well water throughout the year

The bad news is that these organism can cause a variety of physical illnesses. Diarrhea and nausea are the most typical reactions that a person drinking one of these microorganisms would have. The effects are usually short lived but quite acute.

To remove these microorganisms, it’s important to have a well water filter that uses a sub micron filter for removing these and other microscopic organisms that may be in the well. It’s hard to believe but another commonly occurring element in the water supply is radon. Radon is a by product of decaying uranium. This element occurs as a gas but some areas may find this in their well water.

There is no need to panic if radon does turn up in the water supply. The main concern if it is inhaled into the lungs. A carbon based water filter is the simplest solution for removing this substance from the water supply.

So you can see that by simply investigating in systems that have both a sub micron and carbon based filters associated with them, you will be assured of purchasing an effective filtration system.

Your next step is to take what you have learned about well water filters and continue your research. The only way that you can make an informed decision is to know all the facts first. By being informed you can feel confident that your purchase will be right for you and your family.

Pros & Cons of Various House Foundations

Slab, Crawlspace or Basement? When building a new home, which foundation is the best choice? I offer the pros & cons of the typical three choices.


– Least expensive to build
– No moisture/humidity to deal with under sub-floor
– Easy access for handicapped or senior persons, since very close to ground level

– Hard surface, takes a toll on your body/joints
– Difficult to run additional wires/pipes
– HVAC typically located in the attic (unconditioned space)
– A leak in a water supply line in the slab is very expensive to fix
– Entrance at ground level, not as eye appealing
– High likelihood of radon issue (can be easily mitigated)
– More prone to wood destroying insect issues, since close to ground


– Able to install additional wires/piping easily if needed
– Wood floor structure is softer than concrete
– Entrance higher off ground, more eye appealing
– Easy access for repairs
– Less likely to have a radon issue (on ventilated crawlspaces)

– Moisture issues (water & humidity) are a major issues, creates fungus growth & rot
– Easy access for unwanted pests
– HVAC in unconditioned space


– Able to install additional wires/piping easily if needed
– Wood floor structure is softer than concrete
– Easy access for repairs
– Entrance higher off ground, more eye appealing
– HVAC is located in conditioned space (more energy efficient)
– Additional storage/workshop
– Inexpensive additional square footage, can be finished at a later time
– Increased re-sale value of home & increased buyer appeal
– You can build on a sloping grade
– Provides shelter during extreme weather (tornado’s, hurricane’s, etc)

– Most expensive to build (compared to a slab or crawlspace)
– Need a sloping lot to build a walkout basement
– Higher likelihood of radon issue (can be easily mitigated)

How radon was discovered

Radon was discovered in 1900 by a German chemist Friedrich E. Dorn. He called it radium emanation. What he discovered was radon-222, while a scarcer isotope, radon-220, was actually observed first, in 1899, by the British scientist, R.B. Owens, and the New Zealand scientist, Ernest Rutherford. In 1984 a nuclear plant worker in Pennsylvania discovered radioactivity on his clothing while exiting his place of work through a radiation detector. The source of the radiation was determined to be radon decay products on his clothing originating from his home. It wasn’t until then that the medical community became aware of the possible extent of radon related problems.

Radon – an introduction

Radon - 222
Radon - 222

Rn is the chemical symbol for radon. It is a radioactive gas that  occurs naturally and can be found in soils, rock, and water throughout the world. It has numerous different isotopes, but radon-220, and -222 are the most common. Radon is a gas that is created in the soils where uranium and radium are found. Since these elements can be found everywhere in the world any building has the potential for elevated levels of radon. The more uranium found in the soil, the higher the potential for elevated radon levels within that building.

Because radon is an inert (or noble) gas, meaning that it does not react or combine chemically with other substances except under certain special conditions, it can move up through the soil into the atmosphere, where it is easily diluted and presents little concern. However, when radon enters a building, it can build up and become a health concern

You cannot see or smell radon, and there is no way that your body can sense the presence of radon; however, it can have a detrimental effect on the inhabitants by increasing their likelihood of developing lung cancer.

How is radon created?

The presence of Radon in the atmosphere or water is not due to any man made process or other source of pollution, but is mainly derived from uranium deposits in the soil. Uranium (Uranium-238) decays into a stable form of Lead through a series of steps which include the break down of uranium into radium (Radium-226) , which in turn decays into radon gas (Radon-222). Radium-226 and Radon-222 are present in almost all rock, soil and water.

How radon gets into your home!!!

Since radium 226 can be found in low concentrations in almost all rock and soil, it is not a question of “if”, but “how much” radon you really have. Radon is generated in rock and soil and it escapes into the atmosphere through cracks and spaces between the rocks and soil. This results in an average outdoor radon concentration of about 0.4 pCi/L (picocuries per liter of air). At these concentrations there is no real danger. However, if radon is allowed to seep into homes and buildings through cracks and holes in the foundations and walls, the concentration can build up to much higher levels, at which point research suggests there is a reason for concern.

The average indoor radon concentration is about 1.3 pCi/l. Radon concentrations in a home can very depending on several factors including; house design, soil conditions, local geology, and the weather, such as high or low atmospheric pressures, and warm or cold climate. For example, indoor radon levels increase substantially during the winter months. As indoor temperatures increase relative to the outside temperatures, a thermal effect occurs. The rising warm air within a building is displaced by cold denser outside air, some of which seeps in through the foundation cracks, vents, and holes from the underlying soils.

Furthermore, exhaust fans inside the house can create a lower (negative) pressure inside the home relative to the surrounding soil and air, and radon can actually be drawn into the building.
