This weeks segment looks at new technology for detecting harmful algal blooms.

Transcript:

Scientists may soon be able to detect harmful algal blooms from the sky. 

This is the Iowa Environmental Focus. 

A team of researchers at the University of Iowa is developing a drone to detect harmful algal blooms in lakes and reservoirs. It will use remote sensing to collect aerial data with special infrared cameras. Currently, water samples are collected to monitor and detect harmful algae and toxins. 

The most common toxin-producing algae in Iowa is blue green algae, or cyanobacteria. It can cause rashes, gastrointestinal and respiratory problems for beachgoers. Last summer this toxin contaminated drinking water in Greenfield, Iowa. The drone will hopefully make detecting harmful algal blooms easier and allow monitors to catch them sooner.

The project is being funded by a seed grant from the University of Iowa Center for Health Effects of Environmental Contamination, a research center which focuses especially on water quality issues in the state.
