Does a Whole House Water Filter Work if My Home Uses Well Water?

If your home doesn’t get water from the municipal water treatment plant you may be wondering what your options are for water filtration. The level of protection you’ll enjoy when you install a Whole House Water Filter is a common concern many homeowners have.

Starting with the general question of whether a Whole House Water Filter works for you is a good one, but there are additional questions that really get to the heart of your well water filtration needs. We will address these to help you decide if a Whole House Water Filter is what you need and the additional components you should consider.

Primary Uses of Home Well Water Filtration

Most homeowners that utilize water filtration systems install them to do the following:

  • Improve the taste and clarity of their water
  • Eliminate or remove specific contaminants

While all water filtration systems help to eliminate or remove specific contaminants, there may be different impurities that you are concerned about within your well water supply. This is partly why there are different filtration components – such as a sub-micron post-filter and a UV filter – that may be more attractive to some homeowners than others.

Ideally, you should get a water assessment every year to test for the most common pollutants. These tests will look for unwanted items like pesticides, inorganic chemicals, volatile organic chemicals, bacteria, viruses and other undesirables that may cause sickness or that have been correlated with disease.

Health Canada provides some resources for treating well water and mentions that bacteriological testing should be conducted by the provincial health lab in your locale or by a certified private lab.

What is Filtered from Well Water with a Whole House Water Filter?

Contaminants that cause foul odors

It is often cited that well water smells like rotten eggs. This distinctive smell is hydrogen sulfide, a contaminate that exists naturally in groundwater but does not pose immediate health problems in most instances. The activated carbon filter that comes standard in Filter Butler’s Whole House Water Filter will absorb the odor-causing chemicals that give the unpleasant smell created from hydrogen sulfide.

While the presence of hydrogen sulfide in water is generally considered to be harmless, there are sources that reference adverse symptoms and effects from higher concentrations. These symptoms include minor effects like headache and asthma problems to more severe health concerns such as respiratory tract irritation and at extremely heavy concentrations, death.

Bacteria and parasites

If you get your water from a well you are at an increased risk of ingesting water that is contaminated by bacteria and parasites. These contaminants can cause minor health problems but can also be associated with more serious health concerns such as diarrhea, vomiting, chills, fever, headaches, abdominal cramps, and malaise[1]. These symptoms are commonly associated with the cysts Cryptosporidium and Giardia, which the add-on water filtration component, the UV filter, can help to inactivate. The UV filter works in conjunction with the sub-micron post-filter to eliminate bacteria and parasites and dramatically reduce organic and sediment particles. The two components are highly recommended for homeowners who rely on wells to get their water.

How do Contaminants get in My Well Water?

You may have heard that overlying soil acts like a filter for groundwater, helping prevent disease-causing microorganisms like Cryptosporidium and Giardia from entering your water supply. This is generally the case and groundwater is typically a safe option for consumption. Unfortunately, the improper design, installation or age of your well may mean that is it more susceptible to the infiltration of undesirable contaminants than you may think.

This is why it is advised that you test your well water annually and be proactive about keeping your family safe from pollutants in your drinking water with the installation of a Whole House Water Filter.
