Ms. Tachera works with the geochemistry team on ʻIke Wai, collecting precipitation and groundwater samples within Hualālai Aquifer, as well as the surrounding aquifer systems. From these samples, the team gathers geochemical data including major ions (chloride, potassium, etc.), trace metals (arsenic, iron, etc.) and isotopes (ẟ18O, ẟ13C, etc.). These water samples will be used to answer a variety of questions: 1) the degree of connectivity between the high level and basal aquifers; 2) identify the sources of groundwater recharge, from the slopes of Mauna Kea, Mauna Loa and Hualālai; and 3) how subsurface structures affect groundwater flow. Ms. Tachera has participated in quarterly field trips to Kona, Hawaiʻi, where she has had the opportunity to engage with the community and better understand their concerns about groundwater sustainability in Hawaiʻi.
