Water Testing Services

At Structure Tech, we understand the importance of clean and safe drinking water for you and your family. That’s why we offer comprehensive home water testing services to ensure the quality of your water supply.

Water Testing for Homes in Minnesota

Water testing helps determine whether a home’s drinking water is safe and free from contamination. The purpose of testing, especially for private wells, is to analyze the water directly from the source (the well or aquifer) before it’s been treated or filtered. This gives the most accurate picture of the water quality being drawn from the ground.

If the client prefers, we can also collect samples after the home’s filtration or conditioning system or from both the raw and filtered sources for comparison. Please note that taking samples from both will double the cost of testing.

Comprehensive Testing

• Well Water Analysis Sampling Package: This includes testing for Nitrate, Bacteria, and Arsenic. This is the most common package requested and tested for.
• Advanced Contaminant Testing: We can also test for specific contaminants such as arsenic, iron, heavy metals, and more.

What do you test for?

We offer a variety of certified and non-certified tests.

Microbiology

Chemistry – Metals

• *Arsenic, *Copper, *Iron, Lead & *Manganese

Chemistry – Inorganics

*MDH certified

Where We Collect Water Samples

Unless instructed otherwise, our inspectors collect samples directly from the well source. Depending on the home’s setup, water can be drawn from several possible locations:

• Spigot near the pressure tank or well equipment: This is the preferred location because it provides the purest sample from the source. However, it can sometimes be difficult to collect from due to limited space, lack of a nearby floor drain, or risk of contamination if the bottle touches the fixture.
• Exterior faucet: A good option when not winterized. We won’t use exterior faucets that have been shut off for the season.
• Laundry or utility sink: Acceptable as long as the fixture isn’t connected to a filtered or conditioned water line.
• Kitchen sink: Only used as a last resort, since most kitchen faucets contain plastic parts that can’t safely be flamed (a required step for sanitization before collection).

If the client specifically wants water tested after the home’s filtration or conditioning system, we can accommodate this request – just keep in mind that these fixtures almost always include plastic components, so this method carries a slightly higher risk of contamination.

Well vs. City Water Testing

It’s important to know whether a property is on well water or municipal (city) water, since the testing process and sampling bottles differ. City water bottles contain preservatives, while well water bottles do not. Using the wrong type of bottle can produce inaccurate results, so we confirm this information ahead of time.

For MLS-listed properties, our team can typically verify the water source through the listing. For non-MLS homes, we’ll ask the client or property owner to confirm.
