"The Good, the Bad, and the Ugly Aspects of Ordinary Salt " - (ZOOM ODP) - (Zoom link and recording will be sent to registered participants.) This presentation is free with your 2025 PVSC or other Maine Senior College Network membership.
Tuesday January 14, 2025 4:00-5:00 PM – Zoom
No required reading and no examination!
Steve Norton will launch a discussion about what he has learned about various demonstrations done with salt and water, and why it should matter to all people who care about trees, soil, streams, lakes, fishes, and invasive species!
Steve will introduce about 5 or 6 chemical elements (Na, Ca, Mg, K, H, and Cl) and two simple chemical equations. No mathematics. Steve will use PowerPoint images to clarify visually what he says orally.
Presenter: Stephen Norton
My students and I, over the last 5 decades, have studied and reported on the impacts of road salt and marine aerosols. A sobering message is that road salt behaves the same way that acid rain did, stripping elements from the soil that changes the chemical nature of streams and lakes in Maine. The end of this string is a major paper, under construction, that lays out the changes that have been documented in 18 tributaries to Lake George, NY, and the lake itself, from 1970 to the present. There
are some amazing impacts.
