Earthplace set stream-monitoring workshop
Updated 4:27 pm, Friday, October 7, 2011
Harbor Watch, a program of Earthplace nature center, will hold a four-week stream exploration and monitoring workshop for high school students and adults.
The workshop, to be held 9:30 a.m. to noon Saturday, Oct. 15, 22 and 29 and Nov. 5, will explore how the health of a stream and river is measured. Topics will include physical, chemical, bacteriological and macro-invertebrate parameters highlighting aquatic insects.
Hands-on water testing will also be demonstrated with a special emphasis on nutrients and how field measurements can lead to the understanding and detecting of pollution. The correct procedures for sampling and the proper techniques for measuring dissolved oxygen, pH, conductivity, ammonia-nitrogen, nitrate-nitrogen, fecal coliform bacteria and other indicator bacteria forms will be included. There will be a discussion on how field and laboratory instrumentation are used to investigate pollution.
The cost is $50 members and students; $80 for non-members. Handout materials and refreshments will be included.
