How to Filter Well Water

Using water from a Well can be a bit scary. Water filters can help clean drinking water, but what about the Well water your family comes in contact with from showering and brushing their teeth, that can affect the skin and hair that they have to use every day. What is the best way to filter well water? 

Use a Whole House Water Filtration system that contains:

  • Pre-Filter Sediment Removal 
  • Water Softener
  • Carbon Filter (kills Bacteria)
  • Pre-micro-sediment
  • Reverse Osmosis-(Dissolved Contaminants to .01 microns in size)
  • Polishing-Coconut Fiber-UV treatment (kills Virus & Cyst)
  • Minerals-added that were stripped

Most private Wells are supplied with groundwater that is not regulated or controlled. Even when the well is properly maintained, the surrounding environment is constantly changing that can leave your home’s water supply vulnerable to contamination and bacteria growth. How can you ensure that the water of your family is safe?


How to Filter Well Water


The best kind of Water Softener you need is the unit that will reduce minerals that make water hard and soften it by using techniques for removal of the ions that cause the water to be hard, in most cases calcium and magnesium ions. Iron ions may also be removed during the softening treatment process.

In some cases especially when the home is serviced by a Private Water Well, there may be or not be a suspicion of contaminants in the Well. Especially if the Well water has been built on an older property.

Most Wells have problems with hardness, where there is a known amount of extra minerals or iron content in the water supply. This is normal and an easy fix. Indications that your well water has hard water issues is Staining in sinks or toilet bowls.

The homeowner’s best way to resolve this water situation may be to treat the Well water right from the source as it comes and enters the house both with the water softener and a water treatment filtration.

This is called a Whole House Water Filtration Treatment with Water Softening treatment. This water treatment combines the two treatment processes together for the best possible water quality coming from your Well supply.

Whole House Water Filters with Water Softener


The Whole House Water Filtration System that is built for the Well water supply needs a little more treatment than what a normal water treatment filter would give. Well, water could contain contaminants like bacteria which is a common problem with wells.

Bacteria and other contaminants can be introduced into the Well from groundwater through a combination of reasons like intense rain events, construction, and various surface activities.

A common test for bacteria is the total coliform bacteria test. Aside from the Carbon Block that is typical for the removal of bacterial contaminants, other components like Pre and Post filters can be back-washed or removed and replaced. All these filters work in tangents and help to clean the system’s well water.

RO (Reverse Osmosis) Water filter systems contain pre-sediment filters to catch material that can block the filters and destroy their capability. Multi filters reduce a large amount of sediment of all sizes from whole-house water filters that assist in the process.

Water-borne sand, rust, dirt, and such are caught throughout the layers, and stages of the process and get blown away during backwash or can be manually removed by the Pre-Filters.

Filter media like activated carbon can last several years with proper backwash and manual filter cleaning. No chemical regeneration is required, and nothing is imparted into the house water. Whole house filters can remove anything and everything, any size from the point of entry into the house from the well.

Whole House filtering goes the extra step by filtering all incoming potable water that is at risk for contaminants. These filters come in stages with Reverse Osmosis Technology that will remove major health-related elements that make it through your water delivery system down to .01 microns in size.

Reverse Osmosis Technology is a system that uses filters. Just like a filter on a swimming pool. The same concept is used except that the filtering is done on a micron-scale which is a very small scale and an added pressure pushes the water through the small filters trapping small contaminants.

With the use of Pre-Filters, these technical and intricate filtering systems can last for extended periods of time and work more efficiently. You can save a lot of money by keeping the pre-filters clean and working well by setting up a regular maintenance program and keeping the filter clean.

Well Water Filter Systems Diagram


Multi-filters reduce large amounts of sediment of different sizes from the whole house water treatment system.
The filters can use layers of anthracite coal, calcined aluminum silicate, and garnet as media.

Water-borne sand, rust, dirt, and such are caught throughout the layers, get blown away during backwash cycles used as part of the treatment, or are manually cleaned by the owner.

It’s really easy to perform this job and is really important. Original media like activated carbon sometimes will last several years with proper backwash. There are no chemicals involved. Filters remove material physically.

Whole house filters can remove almost anything and everything from the point of entry into the house. It’s a great concept and each component depends on the other for overall efficiency.

When looking for the best well water filtration system, it’s important to take into mind a few factors, including what contaminants the system will filter out, filter size, flow rate, and filter type. Evaluating these factors will help you choose the right water filtration system for a home.

Unlike city water, water from private wells is untreated. This means your water may contain higher-than-acceptable levels of contaminants deemed by the Environmental Protection Agency or your local health department.

To protect your well water from harmful bacteria, Microorganisms, volatile organic compounds, and other common well contaminants, you’ll need to get your water tested annually and treat your water according to the test results. Other contaminants that are removed by Well Water Filter Systems:

  • Sediment-are particles such as sand and dirt that naturally occur in well water, but removing them is important to ensure water is clean and to minimize wear on appliances.
  • Sulfur-too much sulfur, in and of itself, isn’t necessarily bad in drinking water, many detest the smell of sulfur, which can have a rotten egg odor.
  • Iron-Iron plumbing pipes can contaminate water as it enters the house, but iron also can come naturally from the ground. Like many contaminants, low levels are generally not harmful, but high levels are of concern and can cause organ damage, acne, fatigue, and joint pain.
  • Organic chemicals can include pesticides, pharmaceuticals, paints, dyes, and disinfectants that can contaminate well water. Organic chemicals such as these can cause liver and kidney damage as well as damage to the nervous and reproductive systems
  • Heavy metals-include copper, lead, cadmium, arsenic, and chromium. While trace amounts of these metals are generally not harmful, significant amounts of heavy metals can pose health threats, such as an increased risk of cancer, especially if consumed over time.
  • Nitrate can naturally contaminate well water and doesn’t normally pose an issue, but high levels can be a concern. Consuming too much nitrate can cause headaches, nausea, and even an increased risk of cancer.


Tap Water Filter Systems for Home


Besides RO whole house filters there are other alternative systems like UV. Ultra Violet Treatment has been around for decades in water treatment and works well if the water being treated doesn’t contain particulate matter that can negatively affect the operation.

Wells systems that employ this type of treatment for bacteria removal normally uses Pre-and Post Filters to remove finer particulate matter before the well water is treated with Ultraviolet light.

If you decide to go with the UV instead of Carbon Filters or Reverse Osmosis you will still need the Pre-filters along with Post Filters. Higher water pressures may damage equipment and may not allow for proper exposure time with a UV lamp.

The systems are installed so they can be isolated much like all the other components that make up the whole house filtration system. Every component in the well water filter system is plumbed so it can be bypassed and replaced if needed.

Ultraviolet or UV energy is found in the electromagnetic spectrum between visible light and x-rays and is described as invisible radiation. In order to kill microorganisms, the UV rays must actually strike the cell.

UV energy penetrates the outer cell membrane, passes through the cell body, and disrupts its DNA stopping the reproduction of cells. UV treatment does not alter water chemically; nothing is added except energy.

The sterilized microorganisms are not removed from the waterUV disinfection does not remove dissolved organics, inorganics, or particles in the water. By the time the Well water makes it through the system, there aren’t many bacteria leftover from this kind of treatment. The UV is very reliable and has a proven track record to do a great job.


Flow Rate Water Filters


One obstacle for Ultra Violet is that doesn’t use media. Light treatment is it is dependent on time and flow rate which is formulated for each light and treatment system. It also is dependent on any particulate such as sand or dirt that may make its way into the UV Stage of treatment.

As you can see in these pictures of Well systems each component is meant to be taken offline to clean or swapped. Each component is a stage of treatment that has a job to do. Whole House Filters look complicated but in reality, they are not.

The Activated Carbon Filter needs Pre-filters so they can work more effectively. The UV light also needs to be filtered so it has a better kill rate and is more effective. Sediment Filters will add life and allow the overall efficiency of the system to work much better.

If you swapped the UV light out with a Reverse Osmosis Filter it would do the same work but in a different way. The applications may be completely different and the prices will also be something for the homeowner to investigate.

You could use all the methods together to ensure higher-quality tap water. That would also be up to the person installing the system. Reversed Osmosis is becoming hugely popular and inexpensive as the years go by.

Unlike UV which takes nothing chemically from drinking water, the one drawback of RO is the removal of minerals that are stripped away during the process. These minerals are naturally found in water and are healthy.

Wouldn’t you know it, Manufacturers of water treatment systems have come up with a way of using RO and then inserting the minerals back into the drinking water. So this System would add another component. This component would add minerals to the Well water.

Well, water filters physically remove the matter from the Well water. Each of these components except the Water Softener is a filter that uses some filter media that will reduce contaminants by physically removing them or filtering them from the Well water. Water Softeners systems reduce iron from the well water coming into the house.

If you didn’t use this water filter and drank directly from the Well then your body would become the filter and would remove most of the same contaminants and particulates from the Well Water. Unfortunately, those undesirable chemicals, bacteria, and particulate matter like dirt, rust silt, and other nasty things would stay in your body and after a while make you sick. You are just one big human filter absorbing whatever is in the air or water in the world you live in.
