Prof. Dr. Jasper Griffioen is specialised in environmental geochemistry and hydrology. He performs research to stimulate sustainable management of water resources and soil both in the Netherlands and abroad. In his research, he addresses the full suite of activities from 1. geochemical and hydrological monitoring of our environment, via 2. process-oriented field and modelling studies and 3. impact or risk analysis of anthropogenic activities on water and soil quality to 4. establishment of nature-based management solutions using geochemical engineering principles. Preferably, he combines field characterisation and assessment campaigns with modelling studies.

Traditionally, he studied soil and groundwater contamination from agricultural and urban activities especially in relation to drinking water resources and groundwater-dependent ecosystems. For the latter, he recently introduced the concept of zoohydrology, in addition to ecohydrology, to study the two-way interrelationship between hydrology and animals. This was broadened with research on the impacts of geo-energy related activities, where he addresses both the potential of green technologies (aquifer thermal energy storage, hydrogen storage, and also enhanced olivine weathering) and the environmental risks of either these technologies or traditional ones (natural gas production, disposal of radioactive waste). In result, he addressed contaminants such as nitrate, ammonium, phosphate, natural fluoride or arsenic, zinc and cadmium, pesticides, petroleum hydrocarbons as benzene, methane, PFAS and anti-biotics.

Jasper Griffioen also has a research position at TNO Geological Survey of the Netherlands where he is involved in all kind of projects on environmental management of the subsurface with increasing attention for the water-energy nexus. Working at a geological survey, he has performed many projects on the sediment geochemical characterization of the Netherlands, which has given him extensive insights in the sediment geochemical properties of delta areas. 

From all these activities, he has a good overview of new concepts in sustainable management of water quality and soil quality.
