Hayley T Olds
Hayley Olds is a Hydrologist with the Upper Midwest Water Science Center in Wisconsin, where she has worked since 2012.
Hayley Olds is stationed in Milwaukee, Wisconsin. Her research has focused on freshwater quality assessments using both freshwater organisms and molecular source tracking. Hayley has experience with monitoring harmful algal blooms (HABs) composition, toxicity, and spatial extent using low-cost sampling techiques such as Solid Phase Adsorption Toxin Tracking (SPATT) technology throughout the Upper Midwest and Northeast regions, and nation-wide at National Parks throughout the country. Hayley also has experience in assessing benthic invertebrate, phytoplankton, and zooplankton communities, as well as sediment contamination and toxicity, in rivers and streams throughout Wisconsin, including several of Wisconsin’s Lake Michigan Areas of Concern. Over her career, Hayley has been involved in collecting and analyzing ecological data, including algae, invertebrates, fish, sediment, and surveying habitat at a local scale in southeastern Wisconsin's tributaries to Lake Michigan, as well as nationally in the Pacific Northwest, Northeast, and California regions.
