Through its independent citizen science research and consultancy PULSAQUA helps build a sustainable world, leading the field when it comes to water-related environmental problems where society is involved. With our citizen science and water management expertise we help government agencies, NGOs and industries achieve structural change by working together with society.

About the name - PULSAQUA

As you might understand, the name refers to momentum or so called impulsive force, which is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction in three-dimensional space. If m is an object’s mass and v is the velocity (also a vector), then the momentum is

P = M x V

To induce an impulsive force on water, we just multiply input of many citizen scientists (creating a big mass) with a well directed velocity (work done by PULSAQUA and finance from clients).

Therefore, a warm welcome to all (future) citizen scientists and clients, together we will be able to bring momentum and change.


A world where people and companies are aware of their own actions and the effect of those actions for their fresh- and saline water environment, in that way achieving the (water-related) Sustainable Development Goals.


To induce an impulsive force on water issues and awareness concerning these issues by advising, creating and investigating via Citizen Science.


By 2020, have established a name in environmental citizen science research and consultancy.

By 2025, start seeing the effects on the behavior of people, policies and companies towards a sustainable future.

PULSAQUA was founded in January 2019 as a onewomens business by me, Sandra de Vries. I am a Water Management engineer, experienced in project set-up and management, citizen science research methods and connecting science to policy and people. I aim to work with people interested to reach a certain goal, using citizen science methods. I do this in a creative way, not immediately taking the obvious and straightforward route, resulting in surprising and up-beat projects. Topics of knowledge include:
  • Water-related sustainable development goals (SDG) monitoring
  • Mangrove conservation
  • Fieldwork for hydrology purposes
  • Green infrastructure in the urban environment
  • Environmental problems related to water-management
    • Plastic waste in the fresh-water system
    • Groundwater over-abstraction
  • And of course, citizen science
