Where has your drinking water been? Nothing is more critical to local rivers, streams and water supplies than the water that percolates through the soil and bedrock. As Narrowsburg learned in the 1980s, a contaminated landfill will poison groundwater for countless years.

We’ll have a fresh chance to explore the subject at a special program of the Delaware Highlands Conservancy on Saturday, July 26.

John Jose of the Pike County Conservation District will host a program called “Where’s Your Drinking Water Been,” using a groundwater flow model. The model actually circulates water, and by injecting dye, Jose will show how contaminants diffuse underground. He’ll also have tips on how to protect groundwater supplies.

The program begins at 10:00 a.m. at the Conservancy’s Butterfly Barn nature center in Milanville. For more information or directions, visit the Conservancy’s website at www.delawarehighlands.org, or call 570/226-3164 or 729-7053.

Field note. Showy “eyespots” on its large wings caused someone to name the polyphemous moth, pictured above, for “Polyphemus,” a one-eyed giant of Greek mythology. The English naturalist Mark Catesby painted his specimen (second image) while visiting America in the early 18th century.
