Impact/Purpose:

Algae are a natural component of aquatic ecosystems; however, when present in large quantities as "blooms", they can pose a significant potential threat to human and ecological health. These harmful algal blooms (HABs) are often composed of microorganisms known as cyanobacteria, some of which have the potential to produce toxins that can cause adverse health effects in humans and animals through the contamination of waterways used for recreational purposes and as drinking water supplies.

Description:

This project investigates lakes located in three major urban centers in the United States: Cincinnati OH, Kansas City MO/KS and Denver CO. This study aims to determine if there are water quality parameters that are unique to these lakes, and to investigate the correlation between urban watershed characteristics and cyanobacterial blooms. Water samples were taken over the course of one recreational season along with the deployment of time-weighted passive samplers. The study involved the identification of cyanotoxins and cyanobacteria, measurement of urban contaminants such as metals, pesticides, semi-volatile organics and nutrients, and physical parameters.
