The framework for sample collection includes monthly on-site testing
at the sites. Teams of volunteers measure physical and chemical parameters
in the field, using portable, hand-held instruments. Water samples are
collected at each site and are processed in Channelkeeper's laboratory
for bacteria with approved standard methodology (Colilert-18 and Enterolert-24,
manufactured by Idexx Laboratories). Samples are also analyzed at UCSB
laboratories for nutrients (nitrate-nitrogen and orthophosphate). Other
characteristics such as vegetation and aquatic life are recorded during
sample collection on standardized forms. As part of every sampling event,
the instruments and meters are checked and calibrated against factory
standards before taking them out into the field.
