Chemists At Work

Welcome to the virtual Public Service Laboratory.  Join us for an on-line tour.

This tour steps you through an initial request for a water sampling kit, demonstrations of how the chemists test water samples, and a brief discussion of how the results are used.  The final sequence is a portion of an actual tour conducted for area high school students.

Please be aware that you may experience long download times with the video files using a standard modem connection (approximately 30 minutes per 5 MB, depending on modem and speed).
