THE Department of Science and Technology (DOST) has launched a system to monitor water quality to save and preserve fish and marine life in Batangas river.
Called SENTRY (Sensing Environmental Parameters through Telemetry), the system deploys sensors for real-time automated data acquisition to help avoid fish kill and other adverse effects of poor water quality. The devices are in the form of catamaran-type buoys that gather data on the water’s acidity, turbidity, and total suspended solids or particles larger than two microns.
The sensor was installed along Lipote River in Mataasnakahoy, Batangas during the celebration of DOST IV-A’s 52nd anniversary. The sensor will serve as a virtual round-the-clock sentry that will stand guard over particles flowing from the upstream that pollute the river.
Data will be then transmitted, on a per hour basis, to a website which consolidates all other water quality information gathered from various monitoring agencies.
SENTRY is also capable of warning concerned regulatory agencies if a particular data is nearing its critical level. It can also disseminate bulletins and advisories from the Department of Environment and Natural Resources (DENR), Bureau of Fisheries and Aquatic Resources (BFAR), and Environmental Management Bureau (EMB) to local government units (LGUs), fish cage owners and other stakeholders.
DOST Undersecretary for Scientific and Technological Services Dr. Rowena Cristina L. Guevara lauded SENTRY as a collaborative project, calling it as an illustration of “bayanihan in science and technology.”
SENTRY will be replicated in other areas and rivers draining into Taal Lake, specifically polluted rivers and coastal villages, among others.
