Kassandra Einfelt, co-author of this first ever edition, Environmental Explorations has been teaching environmental science at Hawkeye Community College for fifteen years. Her passion for the environmental health of the planet helped sparked an interest in writing this lab manual. Her observations in the classroom and the need for online resources helped foster ideas seen in this publication’s lab exercises. Co-author Dawn G. Keller was instrumental in bringing this publication to fruition and together they look forward to the ever-evolving discipline of environmental science and continued updates of this lab manual.
