There are many reasons why a well owner may be considering adding a treatment system.
Perhaps you dislike the taste or smell, or there is a specific contaminant like lead that you are concerned about. Identifying the reason you want to treat your water will help you make the decision on what treatment system you choose to install.
Next, you will want to do some research. With some many options, this may seem like a daunting task. Look for options that solve the particular issue(s) you are having. Keep in mind that no treatment system removes all contaminants. Many times you have to have multiple treatments to achieve the water quality you desire.
What is treatment device certification, and how do I know if a treatment device has been certified for the contaminant I want to remove?
Treatment device certification is the process of evaluating and verifying the performance, safety, and quality of water treatment devices. This ensures that devices meet specific standards and are effective at treating contaminants they claim to help with. Certified devices are often marked with a logo or mark. It is important for you to look for a certified device since they have been tested and proven effective.
Independent organizations such as NSF, Underwriter’s Laboratory (UL), or Water Quality Association (WQA) have a rigorous process that a product has to pass to ensure that the treatment method will meet your expectations. Both NSF or WQA have webpages you can visit to find products that have been certified to remove certain contaminants.
Who can help me decide what treatment system to use?
The Minnesota Department of Health has create a Home Water Treatment Guide that covers treatment for any common constituent in well water. You should also contact a water treatment professional who can go over the options and help you make the best decision. This is highly recommended if your systems handles a large volume of water or has significant contamination.
