Data Used to Assess Water Quality:

Carpinteria Marsh was originally listed on the section 303(d) list because Regional Board staff observed erosion and sedimentation in the 1980s. This listing basis is faulty because it is not based on any data. Regional Board staff is not aware of evidence to indicate current water quality standard exceedances or beneficial use impacts related to the listing for this pollutant.
