La Palma is experiencing water scarcity and quality reduction year on year. The EU funded Genesis project aims to improve these issues by demonstrating small scale nature-based solutions to the public. Our work with Genesis was to collect and perform on-site testing of water samples within and around different pieces of public and private water infrastructure, as well as surveying the general maintenance level. Our findings show that of the sampled sources, galerías (water galleries) maintained a higher water quality than wells, with lower temperatures, pH values closer to the recommended EU guidelines and lower conductivities. This difference is caused in well aquifers through three separate processes: volcanic gas intrusion, lowering pH and increasing conductivity; saline intrusion, increasing conductivity; and nitrate infiltration from agricultural runoff, lowering pH and increasing conductivity. The maintenance levels of the water infrastructure were very poor, with many galerías being completely overgrown with vegetation and run-down. In the future, successive years of the Genesis HydroCamp will collect additional data to get a better understanding of the hydrology of La Palma. Therefore enabling better informed water management strategies on the island.
