Summary
Task 1. Standard Analysis: Proposals should be prepared based on the current network (18,000 filters per year), with costs given on a per filter basis. The exact number of filters to be analyzed annually is subject to change, based on changes to the network configuration. As described in more detail in the following sections (3.1, 3.2, 3.3), all B module nylon filters shall be analyzed for nitrite (NO 2- ), nitrate (NO 3- ), sulfate (SO 42- ) and chloride (Cl - ), and concentrations shall be reported to the IMPROVE Operations Contractor for incorporation into the larger IMPROVE dataset.
