Environmental Officials Acquire Algae Imaging to Protect NYC Drinking Water

Two instruments purchased from a Maine-based treatment company will monitor source water

New York City’s Department of Environmental Protection has purchased the FlowCAM particle imaging and analysis system from Fluid Imaging Technologies Inc. in Yarmouth, Maine, to monitor source water for the presence of algal cells. Instruments will treat the water for Cyanobacteria and other algae, which can affect the taste and odor of water.

Deployed in water quality laboratories to support the delivery of 1 billion gal of clean water daily to more than 9 million consumers, the FlowCAM VS-4 Algae Analysis model automatically detects the presence of algal cells in water samples, takes a high-resolution image of cells detected and promotes identification with proprietary pattern recognition technology.

Purchased as part of the city’s water quality assurance program, the instruments alleviate the city’s reliance on time- and labor-intensive manual microscopy. The technology is also used to help safeguard drinking water from taste and odor events in Massachusetts, Florida, Indiana, Illinois, Colorado, Oklahoma, Connecticut and other areas.
