Stefan Kalev

Field Research Scientist

Sarasota - M.S. Soil and Water Science, University of Florida. Four years experience.

Stefan received his Master’s degree in Soil and Water Science from the University of Florida after completing his Bachelor’s degree in Environmental Science from the University of South Florida.

Stefan works from our Sarasota regional office where he is currently researching the significant impact reclaimed water has on lake water quality when supplied to lakes directly or through irrigation systems.  Reclaimed water entering lakes greatly elevates phosphorus and nitrogen levels often causing problematic algae and aquatic weed growth, muck accumulation, odor and decreased water clarity if proper lake management practices are not implemented.

Before joining ASI Stephan interned with the National Oceanic and Atmospheric Administration in their Endangered Species Program and with the Florida Fish and Wildlife Research Institute collecting and analyzing water and sediment samples and identifying aquatic specimens.

Stefan enjoys solving complex water quality issues and furthering his knowledge of aquatic ecosystems.
