PFAS in tap water North Holland PWN warning

PFAS in tap water a big offload.

PFAS, also known as poly- and perfluoroalkyl substances, are a group of chemicals that are widespread in our environment. These substances are widely used in industrial processes and products, which means they can end up in our drinking water and food. The presence of PFAS in tap water in North Holland has recently raised concerns and led to warnings from PWN, the region's drinking water company.

It is becoming increasingly difficult for drinking water company PWN to supply North Holland with healthy tap water. The cause? Small industry discharges their wastewater through the sewer and that water flows into the surface water of the IJsselmeer. And PWN draws three quarters of its water from the IJsselmeer lake. Everyone in North Holland thinks the tap water comes from the dunes. There, the water is pumped in and filtered with dune sand for plus minus 3 months.

PWN warns of future cost increase as soon as PFAS in tap water

Who is responsible for monitoring the PFAS toxic discharges? The duty to report and duty to permit are two issues where there is great discrepancy between them. Rijkswaterstaat started a pilot project in 2022 on intensifying monitoring. However, the environment department is beating around the bush.

PWN currently has the capacity and resources to filter some of the toxins from the water. The concentrations may rise further and then PWN will have to opt for less sustainable and costly methods.

Take matters into your own hands against PFAS in tap water and buy a water ioniser with an ultrafine tap water filter which, besides ingesting PFAS, drug residues, microplastics and pesticides, also accelerates the free radicals from your body by oxygenating water.

What are PFAS and why are they a problem in drinking water?

PFAS, or poly- and perfluoroalkyl substances, are a group of chemical compounds characterised by their unique water- and grease-repellent properties. These properties have led to PFAS being widely used in industrial processes and products, such as fire-fighting foams, non-stick coatings and water-repellent textiles. The impact of PFAS on drinking water lies in the fact that once released into the environment, these substances are difficult to degrade and can therefore circulate in drinking water sources for a long time.

A list of PFAS substances includes a listing of the different types of chemicals that fall under the PFAS category, such as perfluorooctane sulphonic acid (PFOS) and perfluorooctanoic acid (PFOA). The explanation of the abbreviation PFAS shows that it is a very broad category of chemicals, all of which have a similar chemical structure and therefore exhibit similar properties and risks. 

How do PFAS get into drinking water?

PFAS can enter drinking water in various ways, including discharges from industrial sites, fire-fighting foam spills at airports and the use of PFAS-containing products in households. Due to the mobile nature of PFAS, they can move through soil and groundwater, eventually ending up in drinking water sources such as rivers, lakes and groundwater.

What are the health risks of PFAS?

Exposure to high concentrations of PFAS via drinking water has been associated with a number of health risks, including elevated cholesterol levels, immune system damage and even cancer. Although epidemiological evidence is still limited, studies suggest that long-term exposure to low concentrations of PFAS may also have negative health effects, especially in vulnerable groups such as pregnant women and children.

How does PFAS affect the quality of tap water?

The presence of PFAS in drinking water directly affects the quality of tap water, as these chemicals can contaminate potential sources of drinking water. The National Institute for Public Health and the Environment (RIVM) has established guidelines on the presence in drinking water to ensure the quality and safety of our drinking water. These guidelines serve as guidance for drinking water companies and government agencies to monitor and regulate concentrations of PFAS in drinking water.

How can exposure to PFAS in drinking water be reduced?

To reduce the amount of PFAS in drinking water, there are several measures that can be taken, including identifying and managing potential sources of PFAS contamination, improving treatment processes and implementing stricter regulation and enforcement regarding the use of PFAS-containing substances.

What are the consequences of long-term ingestion of PFAS?

Long-term intake of PFAS through drinking water can have significant health consequences, as these chemicals can accumulate in the body and cause long-term adverse effects. It is therefore essential to reduce exposure to PFAS in tap water to a minimum to protect the health of the population.
