Temporal Representation: | Data was collected over the time period 1/23/2006-12/12/2006. Salinas watershed is one of five annual rotation areas that are monitored for conventional pollutants by CCAMP staff monthly for one year. Toxicity monitoring is conducted twice during the rotation year (winter and summer) at a subset of sites. |
Environmental Conditions: | Staff is not aware of any special conditions that might effect interpretation of the data. |
QAPP Information: | All data was collected following the Standard Operating Procedures and Data Quality Objectives outlined in the SWAMP QAMP, (Puckett, 2002). QA data are included in submission. All data are flagged as appropriate. |
