<table><tbody><tr><td><p><strong>Challenge</strong><br />Identifying water quality in numerous private wells around Sweden is not always applicable and open data for all those is not available.  There is hypotheses about whether available open data can be used to accurately interpolate the geospatial distribution of chemical properties across different homogeneous groundwater areas in Sweden.<br /> </p><p><strong>Solution</strong><br />A pipeline workflow was setup for consuming, cleaning, analysing and visualizing available open data aiming to investigate which properties are suitable to interpolate and what timespans are suitable. Analysis conducted was based on previous scientific research, with interactive visualization tools. Final kriging workflow was setup to project the interpolated area on top of an interactive map for granular analysis.<br /> </p><p><strong>Value</strong><br />VANA's information portal aims to protect values and promote balanced interactions among Earth's species. It allows environmental experts to share critical knowledge and information, some of which may be endangered, and earn by providing insights needed for environmental permits. Vana´s clients benefit from quick assessments of site suitability, like environmental impact statements. Adding to Vana´s portal geospatial Interpolation of chemical properties in groundwater based on open data opens for evaluation of this feasibility study and creates great value for clients that need this data. Necessity for more dense data became apparent during the feasibility study, which could be arranged by increasing number of users along with suggestions on possible next step focusing on how to improve the data workflow.</p></td></tr></tbody></table>

Feasability study on the application of geospatial interpolation using kriging techniques on chemical properties of groundwater based on open and semi-open data.
