WEB Aruba NV supplies water and power to the Caribbean island of Aruba. WEB Aruba produces electrical energy using steam driven turbine generators. The steam is produced by boilers that burn heavy fuel oil. To meet the growing demand for power, increase efficiency and lower the impact on the environment, WEB Aruba introduced Reciprocating Internal Combustion Engines in 2006. With this technology WEB has increased its reliability and efficiency by approximately 30%.

Container terminal ASTEC NV is located next to WEB Aruba. In 2019 employees of ASTEC started complaining about health problems, probably caused by the exhaust of turbines and engines of WEB Aruba. Enviromen was asked to start 24/7 air quality monitoring. Initially two identical air quality monitors were installed: one monitor at the West border of WEB Aruba, one at the South-East border of Astec, both controlled by WEB Aruba.

The data was shared with Astec. A third air quality monitor (identical to the first two monitors) was installed, next to the monitor on the ASTEC site to validate the data from the first two monitors. Real-time access to the monitoring data was available 24/7 via Aeroqual Cloud software. For several parameters alarm triggers were set, including dust and gases and also for the internal temperature of the monitor, sensor life, etc. This self diagnostic feature is key for maximizing the uptime and guaranteed quality of data.

As a result of conducting continuous real-time air quality monitoring using Aeroqual AQM 65 monitors, WEB Aruba has been able to respond immediately to mitigate any increase in dust and gas emissions; preventing complaints and safeguarding the health of workers and the surrounding community.
