Sampling Methods Requirements

For a complete description and outline of the sampling and analytical procedures
utilized by Project Watershed CNY/SOS, please see the project’s Study Design:
SOPs. 

 

Project Watershed CNY/SOS utilizes a DREL/2000 Portable Water Quality Laboratory, designed by Hach Company, to conduct all analytical chemical testing procedures. Testing for fecal coliform bacteria is conducted with a Hach Bacteriological Membrane/Filtration Lab.  All equipment and glassware are cleaned following a monitoring event.

*Optional

Adapted from the USEPA Volunteer Monitor’s Guide to QAPP, 1996.

 

*Macroinvertebrates may be preserved in 70% isopropyl alcohol, 90% ethyl
alcohol, or 70%-80% ethanol for future reference or quality control purposes. 
Qualified personnel trained in macroinvertebrate identification can identify
preserved organisms following monitoring activities to verify identification
techniques.

We now test with a "flowmeter" as well.
