How is groundwater quality monitored in Mallorca?

Groundwater quality in Mallorca is monitored through a coordinated effort involving various local and regional authorities, primarily the Balearic Water Agency (Agència Balear de l'Aigua i de la Qualitat Ambiental, ABAQUA). This agency conducts regular sampling and analysis of groundwater from multiple observation wells throughout the island to assess the levels of contaminants, including nitrates, phosphates, and other pollutants. These analyses are essential due to the island's dependence on groundwater for drinking water and agricultural use, particularly given the pressures from tourism, urban development, and farming.

In addition to chemical analysis, the monitoring program often includes hydrogeological studies to understand the aquifer systems and their recharge rates. The results are used to inform water resource management policies and sustainable practices, aiming to protect the aquifer from over-extraction and pollution. Furthermore, the data collected is periodically published in reports that provide transparency and inform the public and stakeholders about groundwater conditions. Overall, the continuous monitoring program is crucial for maintaining the quality and sustainability of Mallorca’s water resources.
