| Location | Analyte | Value | Units | Remarks | Location |
|---|---|---|---|---|---|
|
Canoga Creek South Branch (CASB) |
Turbidity | 7.6 | NTU | Lab | |
| Total Phosphorus (as P) | 37.6 | ug/L | Lab | ||
| Temperature | 16.0 | C | Field | ||
| Soluble Reactive Phosphorus (as P) | 20.7 | ug/L | Exceeded 15 min. holding time for filtration; Pre-dilution concentrations for the primary sample and the field duplicate were <17 ug P/L with an abosulte difference of 5.5 ug P/L. A difference of +/-5.7 ug P/L is acceptable for duplicate results <17.0 ug P/L. | Lab | |
| Solids, Total Suspended | 6.29 | mg/L | Lab | ||
| Nitrate-+Nitrite-Nitrogen (as N) | 0.17 | mg/L | Lab | ||
| Kjeldahl Nitrogen, Total (as N) | 0.17 | mg/L | non-detect | Lab | |
| E. Coli | 320.0 | Colonies/100 ml | High RPD between primary sample and field duplicate for E. coli. Absolute difference for raw colony count on each culture plate was small (<10 raw colonies). | Lab | |
| Chloride | 45.0 | mg/L | Lab | ||
