DEP routinely schedules and collects samples for protozoan analyses on a weekly basis, and those data appear below for the previous 6 months. On occasion, DEP may collect protozoan samples at a higher frequency, such as during or after a heavy rainfall. Enhanced sampling data for CROGH appear here.
