Information: This page contains information on event mean concentrations for phosphorus and suspended sediment derived from the National Stormwater Quality Database. This data was updated in March, 2020, and we include the updated information and the table with the older information. We recommend using the updated table or data contained in this table, which provides a more comprehensive and up-to-date summary for event mean concentrations.
