Common use of Reporting Limits Clause in Contracts

Reporting Limits. Provided below is a list of maximum acceptable reporting limits and units for various constituents in aqueous, sediment, and tissue matrices. Contractor may not deviate from maximum acceptable reporting limits without approval of County. Contractor must provide laboratory and electronic data report (EDR) results in the units specified in the following table. Contractor must provide reasonable explanation for alternate proposed reporting limits.
