About GAP Wiki

GAP is not only an online repository for groundwater quality-related data but also serves as a platform for data sharing and information exchange. With the "Community" functionality, users can create and manage user groups, which can facilitate data sharing in a secure environment, fostering collaboration on specific case studies.

The GAP Wiki features information on various topics related to groundwater quality and successful mitigation: water sampling and analysis, treatment technologies, financing mechanisms and techniques to induce lasting behavioural change. Contributions by users are encouraged and moderated by GAP staff.

Who uses GAP?

The services provided by GAP – mapping, modelling, information exchange – are aimed at a diverse group of stakeholders and cater to different interests and needs. Currently, users from 140 countries have registered on GAP and come from a variety of sectors, including academia, government, NGOs, the private sector and industry.
