The city of Bruges is using sensors in its canals to monitor water quality to detect blue-green algae bloom.
Blue-green algae, technically known as cyanobacteria, is potentially toxic. It can harm both humans and animals which come into contact with or ingest the contaminated water. Side effects can include skin irritation, headaches, and gastric, intestinal and respiratory disorders, as well as allergic reactions.
"With global warming, their growth has accelerated in surface waters. We have invested in a connected sensor, positioned on the Carmerbrug," explained Environment and Climate councillor Milou Esquenet.
This location was chosen because several canals flow through it, and the Lange Rei, which runs beneath the bridge, is occasionally the site of swimming competitions.
The sensor continuously measures water quality parameters, such as oxygen levels, acidity, and temperature. This data analysis enables the detection of sudden changes, indicative of contamination.
"If abnormal values are detected, the environmental service will receive an alert and can take measures," the official assured.
