Common use of Sampling Frequency Clause in Contracts

Sampling Frequency. Sampling for public health monitoring under this plan will occur at each of the identified sites as listed in Table 2. Public health sampling in Upper Klamath Lake and Keno, X.X. Xxxxx, Copco, and Iron Gate reservoirs will begin in May. Public health samples will be submitted for cell-count analysis only from May (ODEQ and PacifiCorp sites only), June, and July and analysis of all samples will be rushed. After July, no cyanobacteria samples will be analyzed. Samples will continue to be sent to EPA for microcystin analysis throughout the season. Public health memos will include the microcystin toxin data as it is received from the EPA lab. Monitoring data from previous annual public health sampling efforts (2005- 2019) indicates that Microcystis cell counts and/or microcystin levels in non-river samples (Iron Gate and Copco reservoirs and Upper Klamath Lake) typically remain elevated until cooler weather and shorter days terminate the blooms.
