Water Treatment Standards | Water Testing MN

Although U.S. water supplies rank as one of the safest in the world, some contaminants still can enter the drinking water after it has left the treatment facility. Installing a water treatment system offers you more control over the quality of your water.

While no federal regulations exist for residential water treatment devices, there are several voluntary national standards that establish minimum requirements for the safety and performance of products used to treat home drinking water.

These standards are generally divided according to the technology used by the product. The numbers assigned to each standard reflect the order in which the standards were developed.

Below are the standards and the type of technology each covers, along with a description of the purpose or intended function of the technology.

Adsorption/Filtration (NSF/ANSI 42 & 53)

This process occurs when liquids, gases, dissolved or suspended matter adheres to the surface of, or in the pores of, an adsorbent media.  Carbon filters would be an example of this type of product.

Softeners (NSF/ANSI 44)

These systems incorporate a cation exchange resin that is regenerated with sodium or potassium chloride. The softener reduces calcium and magnesium ions and replaces them with sodium or potassium ions.

Ultraviolet Treatment (NSF/ANSI 55)

These systems use ultraviolet light to disinfect water (Class A systems) or to reduce the amount of nondisease causing bacteria in water (Class B).

Reverse Osmosis (NSF/ANSI 58)

A process that uses reverse pressure to force water through a semi-permeable membrane.

Most reverse osmosis systems incorporate one or more additional filters before or after the membrane.

Distillers (NSF/ANSI 62)

These systems heat water to the boiling point, and then collect the water vapor as it condenses, leaving behind contaminants such as heavy metals. Some contaminants that convert readily into gases, such as volatile organic chemicals, can carry over with the water vapor.

Shower Filters (NSF/ANSI 177)

These products attach directly to the pipe just in front of the homeowner’s showerhead.

Keep in mind that claims of being certified to an NSF/ANSI standard do not mean that a product will be able to effectively reduce a specific contaminant. As a result, it’s important to verify that the product is certified under that standard for reduction of the specific impurities of most concern to your family.

If your water is not as pure as bottled water, the water treatment and filtration experts at All Ways Plumbing, Inc. could suggestion a simple and inexpensive water purification system that would bring it to that level of purity, thus relieving you of the bottled water expense and inconvenience.

A never-ending supply of drinking water is something that many of us take for granted. We simply turn on the tap and there it is. Do you know where your drinking water comes from or how its quality compares to other water sources around the country?  Many people now use home water treatment devices, but how do you know which product is right for you? If you live in the suburbs of Minnetonka, Maple Grove, Plymouth, St. Louis Park and Edina you draw your water primarily from the Prairie du Chien-Jordan aquifer and might be astounded at how “hard” your water is and how much you might benefit from simple forms of water treatment and purification!
