Check your pet
We are working with the municipalities of Uitgeest and Heemskerk to ensure clean and healthy water. To this end, we are collaborating with Velt (the Association for Ecological Living, Cooking, and Gardening) to conduct research into substances that can end up in the water via pets.
Do you have one or more dogs or cats? If so, you can help us.
Check on your pet
We are investigating which substances pets carry on their bodies. These substances may come from the use of products such as flea treatments. Through hair and dust, these substances can eventually end up in surface water.
By gaining a better understanding of this, we can work more effectively toward clean water for people, animals, and nature.
How it works
If you participate, you will receive a test kit. It contains:
- a vacuum cleaner attachment;
- a tube for collecting hair and dust;
- a return envelope;
- clear instructions.
You can easily collect a sample at home, and we’ll pick it up from your home or you can drop it off at city hall.
Participation is free
Participation is free. We'll take care of everything.
As a thank-you, you can pick up a free dog or cat treat at Welkoop in Heemskerk. After signing up, you will receive a code for this.
Various participants
To ensure a representative sample, we are looking for participants from different parts of the municipalities. That is why we will be selecting participants from among the applicants.
You’ll hear back soon to let you know if you’ve been selected. Even if you aren’t selected, we’ll keep you updated on the results—if you’d like. And you’ll get the treat for your dog or cat either way!
You can register untilMay 17, 2026.
