Monitoraggio delle acque – Riqualificazione del Molo VI, Porto di Trieste

Da ottobre 2024 a ottobre 2026 stiamo realizzando un ampio programma di monitoraggio ambientale nell’ambito dei lavori di riqualificazione e ricostruzione della Banchina VI del Porto di Trieste. Le attività sono incentrate sul monitoraggio della torbidità e della qualità delle acque, in piena conformità con il Piano di Monitoraggio Ambientale e con la normativa ambientale italiana vigente (D.Lgs. 152/2006, D.M. 173/2015, D.M. 489/2015), sotto la supervisione di ARPA FVG.

The program is structured into the three standard monitoring phases:

• Pre-construction (ante operam): two monitoring campaigns were carried out to establish baseline turbidity and key physico-chemical parameters of the water column. A multiparameter probe with turbidity sensor was installed near the quay, providing threshold values for comparison in later phases.

• During works (in corso d’opera): throughout construction, the multiparameter probe remains in continuous operation, recording and transmitting data at regular intervals. In addition to turbidity, the system measures wind, temperature, pH, redox potential, conductivity, salinity, dissolved oxygen, suspended solids, and chlorophyll, ensuring real-time environmental control and enabling rapid mitigation measures if agreed thresholds are exceeded.

• Post-construction (post operam): following completion, monitoring continues for one year through two 15-day continuous campaigns, conducted every six months. These activities verify the return of turbidity and water quality to baseline levels and confirm the absence of lasting impacts on the marine ecosystem.

In accordance with contractual agreements with the Port Authority, the monitoring service will continue for an additional year beyond the post-construction phase, resulting in a total duration of two years.

This structured approach, combined with the use of state-of-the-art multiparameter probes, ensures continuous oversight of the marine environment during all stages of the Pier VI redevelopment, safeguarding compliance with regulatory requirements and protecting the surrounding ecosystem.

Duration: October 2024 to October 2026
