Hydroprobe

LEO student interns operate a hydroprobe on the lower reaches of the Lehigh River. The probe measures temperature, pH, specific conductance-resistivity, salinity-TDS, dissolved oxygen, and redox potential. LEO interns operate and maintain the probe, organize the data, which is logged on an hourly basis, and analyze the results for a segment of the Lehigh River near Bethlehem. This data is then collected into a database which you can access using the on-line form. Data collection began with LEO on 1998-10-29. Some days may not contain data due to maintenance and technical difficulties.

In addition, LEO has obtained data from Parkland High School. Data collection began 1998-01-06. This is a joint project in partnership with the Wildlands Conservancy and Parkland High School. Bob Miller is the contact person at Parkland High School.
