What is the pH value tap water Netherlands?
pH value tap water Netherlands is a frequently searched search term. As well as ph value drinking water and ph value tap water. pH is an abbreviation of the French words Pouvoir Hydrogen and this indicator measures the acidity of water. The pH value is one of the most important indicators for all living things in or out of water. A human being raised in water as an embryo and fully grown baby. We often forget this as adults. The pH scale covers the range of 0-14. The 0 pH value implies that you have very acidic water. If the pH is higher than 7, we talk about alkaline or basic water.
What is the pH level of tap water in the Netherlands, and what does this tell us about the quality of your drinking water? Tap water in the Netherlands has an average pH of between 7.5 and 8.5, which is slightly alkaline. Water companies adjust the pH accordingly because water with too low an acidity corrodes pipes and can leach harmful substances such as lead or copper.
In practice, this means that the water you drink at home is chemically safe, but not necessarily optimal for your body. The pH level varies by region and season. If you consistently drink water with a pH level closer to neutral or slightly higher, you’ll be providing your body with better conditions. The result follows: the acid-base balance in the blood remains more stable.
Dutch tap water has pH values around 7 to 8.5. However, this value can vary from day to day and from city to city. The higher the pH above 7, the more alkaline the solution. In the household, for example, soap is known to have a pH around 10. Acidic solutions have a pH below 7. The lower the pH is below 7, the stronger the acid. For example, a strong acid is concentrated hydrochloric acid with a pH lower than 1.

Complexity of the pH scale
Water has the chemical formula H₂O. This means that each water molecule contains two hydrogen atoms (H) and one oxygen atom (O). These water molecules then break down into negatively charged hydroxide ions (OH⁻) and positively charged hydrogen ions (H⁺). In general, therefore, the molecule is neutral.
The pH value of water is determined by the concentration of hydrogen ions. Before we continue: to avoid having to work with awkward numbers, the pH value is defined as the negative logarithm of the hydrogen ion concentration. For a hydrogen ion concentration of, for example, 0.01 mol/l (= 10⁻² mol/l), the solution in question has a pH value of 2. The higher the hydrogen ion concentration, the lower the pH value. For example, if the value is reduced from 7 to 6, the concentration of hydrogen ions will be ten times higher.
Measuring pH
You can measure the pH value of tap water in the Netherlands in various ways. For instance, there are strips of paper with colour codes on them. This can be put into water after which the strip changes colour. That it produces inaccurate measurements is a big disadvantage, despite the big advantage of these strips is that they are very cheap. To accurately measure the pH value of tap water, it is best to use a digital meter. They can measure pH values to the nearest tenth.

Adjust pH with an alkaline water ioniser
Alkaline or acidic solutions can then be used to adjust the pH level. These products, which come in the form of minerals and salts, are known as pH Down or pH Up products. Examples include minerals and salts such as bicarbonate tablets, which are dissolved in tap water. Alkaline water ionisers or oxygen generators also help to create – or rather, to adjust – the pH level. On the other hand, water ionisation devices also enable the production of alkaline drinking water. Their far more important function, however, is to produce oxygen-rich water, which contributes to our health.
It helps our bodies speed up the elimination of free radicals - toxic acids. The third function is to filter tap water at the nano level while retaining its minerals. This stops plastic - and asbestos particles in a home water filter in the water ioniser.
Alkaline or alkaline water what is it?
Alkaline water has a lower acidity level than tap water. This means it is rich in “alkaline compounds”, including magnesium, bicarbonate, calcium and potassium. It can neutralise acids in your blood and help your body absorb nutrients more quickly. The pH of tap water is almost 7. We call this a neutral pH. Alkaline water, on the other hand, has a pH above 7.
Health claims of pH
We have compiled a list of various claims, incorporating the latest research findings.
- With alkaline water, you put less strain on the body.Our body has a self-regulating system in which organs each require a slightly different pH. The pH level of drinking water hardly affects this. You extract slightly less salts from your body. To balance 1 glass of cola, you need large amounts of ph 10 value water. What supports the body much better is drinking water with a high ORP value. An index to measure the oxygen richness of water. Oxygen-rich water accelerates the elimination of free radicals, as it is packed with antioxidants. So this claim is true.
- Alkaline water supports athletes
Hydration helps athletes recover faster. Water is measured for this purpose with the ORP value or oxygen content. The pH level of tap water is unrelated to this. The pH level of tap water in the Netherlands is perfectly fine. However, the ORP level of tap water is far too low. Moreover, there is scientific evidence to support this claim. This claim is therefore untrue.
- Alkaline water helps remove toxins
Alkaline water supports an alkaline diet. It helps the body to maintain its pH balance more easily. Furthermore, internal regulatory systems that rely on salts need to use less stored energy. Toxins or free radicals are flushed out more quickly by the much more active blood, thanks to oxygen-rich water with a high ORP value. So this claim is not true.
Can you make alkaline water?
Local tap water may be more acidic but how can this be remedied. The Netherlands' 10 water utilities aim to provide tap water with a neutral pH. Our advice is to buy an Alpha water ioniser. This creates alkaline oxygenated ultra-fine filtered drinking water through an electrolysis process. Ionised water has proven its power as various medical examinations to the use of oxygenated drinking water demonstrate this.

To purchasing a water ioniser To justify this choice and take pride in it as a health decision, it is important to realise that the ORP value indicates the oxygen content of drinking water. However, this value is a much more important indicator than the Water pH value.
Frequently Asked Questions
What is the water quality of Dutch tap water, and what role do the pipes play in this?
Tap water in the Netherlands is generally safe to drink. However, the pipes have a significant impact on its quality. Old copper or lead pipes can leach metals into the water because the water is in prolonged contact with the material. This alters the acidity and the taste. In newer homes, the pipes are often made of plastic. These release fewer substances. If you want to be sure of what’s coming out of your tap, you can have a water test carried out. A specialist can help you understand the results and decide whether a water ioniser would be beneficial in your situation.
Do PFAS substances pose a risk to the quality of my drinking water?
PFAS are substances that are difficult to break down and end up in the environment. They can enter drinking water via groundwater. In the Netherlands, drinking water companies monitor PFAS levels very closely. Concentrations in tap water are generally below the European standard. Nevertheless, some people opt for additional filtration as a precautionary measure. A water ioniser with a good filter can reduce certain contaminants. If you’d like to know which filter is suitable, ask an expert who understands water filtration and ionisation for advice.
What is the difference between osmosis water and water with a high pH level produced by an ioniser?
Reverse-osmosis water is highly purified. It contains hardly any minerals and has a low acidity level. This makes it more acidic than alkaline. Water with a high pH from an ioniser, on the other hand, is alkaline and does contain minerals. These minerals are good for your metabolism. Reverse osmosis water often tastes flat. Ionised water with a higher pH tastes fresher to many people. Both options have their pros and cons. In short, which one you choose depends on your health needs and the quality of the tap water in your home.
What are the frequently asked questions about using a water ioniser for daily drinking?
Many people wonder how to set up and maintain an ioniser correctly. The filters need to be replaced regularly, usually after three to six months. The electrode plates also require attention: flush the appliance weekly on the acidic setting. This prevents limescale build-up. People also often ask what the best pH level is for everyday use. For drinking water, this is generally between 8.5 and 9.5. The staff at gezondwaterdrinken.nl are trained to advise you on the correct settings for your situation.
So what are you going to do with this knowledge of pH?
Knowing the pH level of your tap water is the first step — knowing what to do with that information is where the real impact lies. A water ioniser adjusts the acidity directly at the source: your own tap. This means you can drink water every day at the pH level you consciously choose.

pH value of tap water In the Netherlands, tap water is generally slightly alkaline, with a pH value that is almost always between 7.0 and 8.5. Water companies monitor this closely, as a pH that is too low or too high can corrode pipes and affect the taste. If you want to be sure that your tap water falls within the safe range, you can easily test it yourself using a pH meter or test strips — this will give you an immediate insight into the ph value of tap water.
