On February 12, 2025, a sample for mercury was collected, but was not analyzed due to a contract lab error. |
To prevent further reoccurrence, the LADWP Wastewater Quality and Compliance Group and Environmental Laboratory will carefully review COCs from contract laboratories before analysis takes place. |

DMON |
The Harbor Generating Station (HGS) NPDES Permit No. CA000036 requires the effluent (EFF-001) to be sampled annually for Nitrate-Nitrogen, Ammonia-Nitrogen, and Xylene.
On February 27, 2023, a sample was collected for the purpose of annual analysis. Nitrate-Nitrogen and Ammonia-Nitrogen were not analyzed due to an oversight in the sample request to a contract laboratory which does not typically run analysis for the HGS NPDES permit. Xylene was not analyzed due to the contract laboratory using an analytical method for volatile organics which does not include Xylene as an analyte (EPA 624.1 rather than EPA 8260B). NODI (E) has been noted on the DMR forms to indicate this.
|
To prevent future reoccurrence, the LADWP Wastewater Quality and Compliance Group will carefully review COCs and sample requests, particularly when analysis is requested from contract laboratories that typically do not perform analysis on the HGS NPDES permit. Also, sufficient time will be given to plan sampling and laboratory coordination. |
