One of the most effective ways to address arsenic in Wisconsin home drinking water is through reverse osmosis (RO), which uses a specialized membrane to remove contaminants at the molecular level. RO systems are commonly installed under the kitchen sink to provide safe drinking and cooking water, but they can also be scaled up for whole-home use. For households seeking full protection across all taps, point-of-entry (POE) systems—such as whole-house reverse osmosis, ion exchange, or adsorption units using activated alumina or iron-based media are available. These larger systems ensure that not only drinking water but also water used for bathing, cleaning, and laundry is treated, offering comprehensive protection for the entire household. Diamond H2O can help you select and install the appropriate solution for your home.

What is Arsenic?
Arsenic is an element that occurs naturally in soil and bedrock formations. It is tasteless and odorless in water and can only be detected by testing.
Where is it Found?
Since arsenic is a natural part of our environment, everyone is exposed to small amounts. The major source of arsenic exposure is drinking water that contains elevated levels of arsenic. Traces of arsenic are also found in groundwater, lakes, rivers and ocean water. Other sources of arsenic exposure include: foods containing traces of arsenic, smoke from wood, coal, tobacco products, dust from some industrial processes, pesticides, anti-parasitic veterinary medicines, folk remedies, and some treated lumber. Some fruits and vegetables absorb traces of arsenic from the soil they grow in. Ocean fish and seafoods naturally have high levels of an organic non-toxic form of arsenic.

Test Your Water
Confirming the presence and concentration of Arsenic in your drinking water help determines what options are available for treatment. Additional testing (of Silica, Sulfate, Nitrate, pH, Iron, TDS, and alkalinity) may be required to determine expected lifespan of different treatment options. TGA Labs, a state certified laboratory, works directly with Diamond H2O to determine the best arsenic water filtration solution for your home.

Determine the right system for you
Determining the right arsenic water filtration solution is about half science and half art. Our experts will consider all factors like the ones below to determine the right arsenic removal system for your home.
- Size of the Home
- Water Quality
- Other Interacting Systems
- Plumbing
- Available Space for Equipment
- Other Goals for Treatment

Enjoy your Water!
When your arsenic filtration system is installed, you can begin enjoying your home’s drinking water! While our systems primarily target the removal of arsenic from water, you may notice other benefits as well. This could range from removing silica (which may cause staining) to reducing ions – all of which help produce relatively pure drinking water. Don’t forget to ask your experts what other benefits your system will have based on your water quality.

After Install
Although your new equipment to remove arsenic from your water will work when installed, it will eventually require maintenance. This is especially important when treating health concerns like arsenic in drinking water. The maintenance required will be dependent on your usage and water quality, which is why testing your water ahead of time is so important. While systems may last longer than 20 years, maintenance may be required anywhere from every year to every five years. Our experts will leave you with a maintenance plan and can even set up reminders to give you confidence in your arsenic filtration system and ensure your water remains arsenic free.
