Water Quality

Chemicals, algal blooms, and pathogens are measured and monitored to assist beach health and other water quality programs.

Water Quality Research Activities

Clean drinking water is necessary for human health. Contaminated water can cause illness in human, domestic and wild animal populations. Assessing the quality of water is important to predict natural and anthropogenic affects, alert the public to contamination and initiate processes to improve water quality. Research include the detection of the number and types of microorganisms in waters and develop ways to assist communities in keeping the microbial content of water supplies at a low level.
