Spatial Representation: | The samples were taken at three locations: sd1, sd2, and sd3.
Sd1 - Bake Parkway: This site is located off of Irvine Center Drive on the right hand side before the Wild Rivers water park. Sd2 - 133 Fwy: The 133 Fwy is located off of Pacifica and Alton in the dead end down the ramp in the riverbed. This area is just downstream of SD1 Bake Parkway, yet has never been dry. Sd3 - Sand Canyon : The Sand Canyon site is located off of the 405 freeway at Sand Canyon avenue past Alton at the bridge on the northeast corner of Barranca and Sand Canyon avenue. There is a pullout with a chain gate. |
Temporal Representation: | The samples were collected monthly starting on December 23, 2003, at Sd1 and Sd3, through June 21, 2004. Monthly samples were also collected at Sd2 starting on October 22, 2002 through June 21, 2004. |
Environmental Conditions: | Staff is not aware of any special conditions that might effect interpretation of the data. |
QAPP Information: | The data's quality is deemed appropriate because it was obtained under the auspices of a QAPP approved by the Regional Board. |
