Adasa showcases the capabilities of aquaTest at the 5th Spanish-Portuguese Symposium on Marine Intrusion Technology in Coastal Aquifers

 

Raúl Alonso, Water Sensors Sales Manager at Adasa, presented the value proposition of aquaTest and DropletSens at the 5th Spanish-Portuguese Symposium on Marine Intrusion Technology in Coastal Aquifers (TIAC 2026). The event took place at the Casa del Mediterráneo in Alicante, located in the former Benalúa Station building.

During the session on the monitoring of physico-chemical parameters, Alonso explained that Adasa provides the entire water cycle with a range of advanced solutions based on continuous measurement. These solutions provide essential information for determining the condition of water bodies and diagnosing the source and causes of any changes in their condition.

The first solution is aquaTest, a system developed by Adasa for the continuous monitoring of water quality, the detection and characterisation of discharges and collectors, and the operation of treatment plants.

How does it work? aquaTest integrates into a single device the automatic, autonomous and continuous measurement of the following indicators that determine water quality: pH, redox, temperature, conductivity, turbidity and organic matter via the SAC indicator (and its correlations with BOD, COD, TOC) and optional parameters such as dissolved oxygen, nitrates, chlorophyll or phycocyanin.

Alonso went on to explain that Adasa determines the presence of nutrients in water by installing DropletSens equipment at its facilities; this is a range of fully quantitative, submersible automated analysers that use an internal standard for self-quality control. Among its advantages are very low energy and reagent consumption, the fact that it produces no external waste, and the ability to operate either continuously or intermittently.

Finally, one of the conclusions presented by Alonso at TIAC 2026 was that measuring the physical and chemical parameters of water provides valuable insights, particularly when the interactions between the various indicators are taken into account.

TIAC 2026, which saw broad participation from numerous experts from both countries—including representatives from government bodies, public enterprises and the private sector—not only analysed coastal aquifers but also their importance in water management and during periods of drought on the mainland and islands of Spain and Portugal.

The technical meeting was organised by the Groundwater Club in collaboration with the Directorate-General for Water at MITECO, the CSIC-IGME, the Spanish Association of Hydrogeologists, the National Association of Mining Engineers and the Provincial Council of Alicante.
