Test Your Water

Find out what’s
in your tap water

Ignorance is not bliss when it comes to our health

Over four billion people worldwide have access to tap water.

Yet, contaminated supplies, chronic pollution, inefficient treatment methods, unreliable distribution networks, and an increasingly array of factors pose significant challenges for maintaining safe drinking water.

How do you know if your tap water is really safe? Put it to the test.

Your water is tested by experts

The Horn & Co. Analytics GmbH was founded as a neutral, independent and accredited test laboratory in 1994. Since then, it has been certified according to ISO/IEC 17025 and stands for speed and precision in the areas of material, environment and hygiene. The many years of experience of their qualified employees from the fields of chemistry and microbiology guarantee individual problem solutions that are based on the needs of the industrial, public and private customers.

As a drinking water test center approved by the State Office for Nature, Environment and Consumer Protection, we guarantee you standardized analyzes in accordance with the Drinking Water Ordinance.

Why test your water?

Why should I test my tap water?

Your tap water potentially contains contaminants that are harmful to your health. In Germany, water companies deliver clean water to your house and control its quality till the point-of-entry. However, it is not ensured that the water coming out of your kitchen tap (point-of-use) has the same quality. So, it is recommended to test your tap water regularly (once a year) to make sure there are no pollutants in your water.

What is included in the water test?

Your purchase contains a box of all relevant water testing materials to your door, and also express shipping back to the laboratory. The package includes two water sample bottles and cooling pads. The water analysis consists of 5 parameters: copper, lead, chromium, nickel and bacteria colonies at 22°C and 36°C incubation temperature.

How does it work?

Conducting a home water test is very simple and doesn’t need much time and effort. After purchasing your water test, our lab partner will send you a package with cooling material and empty water bottles. When you receive the package, you will have to do the following:

1. Freeze the cooling pads overnight.
2. Take a water sample in the morning between Monday to Wednesday.
3. Put the coolpads and water samples in the package and seal it.
4. Attach the express post stamp (included in the package) and bring it to your closest post office with express service.
5. You will receive your results after one week.

Why are these contaminants bad for me?


The element copper is of natural origin. Copper pipes or components containing copper can lead to an increased concentration in drinking water, potentially causing liver and kidney damage to infants and young children.
Threshold value: 2mg/l


Lead is a heavy metal that was used until 1973 for drinking water pipes which are still used in many places today. This is the most common cause of increased lead content in drinking water. Lead is highly toxic to humans, as it can accumulate in the body, even when small amounts are ingested. If lead is deposited in the body, it is excreted very slowly. In this way, it can cause chronic poisoning, which manifests itself in headaches, fatigue, emaciation and defects in blood formation, the nervous system and muscles. These lead poisonings are particularly dangerous for children and pregnant women.
Threshold value: 0,01mg/l


In nature, chromium only occurs in compounds with other elements. Natural spring water contains very small amounts of chromium compounds. Chromium is used, for example, in the manufacture of stainless steels and for alloying, which means that the pipes in drinking water installations may be the cause of increased chromium content in your water. Some chromium compounds can trigger allergic and asthmatic reactions.
Threshold value: 0,05mg/l


The heavy metal, nickel, is mainly used for alloys. It usually gets into drinking water through nickel components in the fittings and pipes. Nickel is harmless to humans in small quantities. However, higher concentrations pose a health hazard, causing discomfort and nausea.
Threshold value: 0,02mg/l

Bacteria 22°C & 37°C

The colony numbers at 22 °C and 37°C incubation temperature (not water temperature) give a general overview of the hygienic condition of the extraction point and/or the water supply system. Increased colony numbers often occur after work on the pipe network, in old pipelines or after a longer water service life. Different colonies grow at different temperatures, so the colonies can only be found during the examination at the bespoken temperature points and depending on their characteristics they may or may not be harmful to humans. Our test results indicate the amount of colonies at this temperature. If the amount is greater than the recommended threshold then you may want to investigate further or find other drinking water solutions.

How do I know that I am getting reliable test results?

We scouted the most reliable water examination laboratory and chose to work with the Horn & Co Analytics GmbH. They are certified by DIN EN ISO/ICE 17025 : 2018 and have been in business since 1994.

Why is Mitte offering water tests?

At Mitte, we concern ourselves with water quality on a daily basis. We believe that water quality is a fascinating and important topic that could be spoken about more. This naturally extends to the question: Is my tap water good enough to drink? This water test will give you some insight on the quality of your tap water so you know exactly what you are consuming on a daily basis. And should you want to consider alternatives to drinking tap water, then we have the perfect solution that provides not just clean, but also mineral-enhanced water, for you.

Is it possible to test other water contaminants you haven't listed?

If you’re interested in testing other water contaminants that we are not currently testing, please feel free to send an email to [email protected]. We will let you know as soon as we are able to test that contaminant.

Discover Mitte

Mitte is the first of its kind smart home water system that purifies and enhances water through a process inspired by the natural water cycle. It works in two simple steps: first, it purifies water with a proprietary distillation-based method, then it enhances the purified water with essential minerals.
