Event mean concentrations by land use

NOTE: This page originally contained information from the National Stormwater Quality Database. We recently completed a literature review of event mean concentrations of total phosphorus and total suspended sediment in stormwater runoff. We recommend using information from this recent review rather than the data from the National Stormwater Quality Database.

• Event mean concentrations for total phosphorus - this is a table of event mean concentrations for total phosphorus, by land use
• Event mean concentrations of total and dissolved phosphorus in stormwater runoff - this page provides information and guidance related to event mean concentrations for total phosphorus
• Event mean concentrations for total suspended solids - this is a table of event mean concentrations for total suspended solids, by land use
• Event mean concentrations of total suspended solids in stormwater runoff - this page provides information and guidance related to event mean concentrations for total suspended solids
• National Stormwater Quality Database-derived event mean concentrations for phosphorus and TSS - data originally contained on this page
