Pesticides listed at 40 CFR section 125.58 (P) for Demeton, Guthion, Malathion, and Parathion were not analyzed or reported for PL influent of effluent due to incorrect method of 8270 and not 625.1 listed on chain of custody for January 2024 sample. When this error was discovered, the outsourced lab was contacted and informed to update the requested analysis. The outsourced lab was experiencing personnel issues and the request for the method correction was miscommunicated, although the correct method of 625.1 was annotated on the quote for services. Frequent correspondences with the lab were not effective due to staff changes where three lab mangers cycled through. |
To avoid this reoccurrence will include a thorough review of the chain of custody will be performed by the project support group and the supervisor of the ECS pesticides group prior to sample outsourcing. Also, direct communication with outsourced lab will be documented and included as an attachment with the chain of custody. |

Settleable Solids Instantaneous Maximum limit is 3.0 ml/L and reported value was 5.0 ml/L at EFF-001. |
Subsequent daily analytical results for this parameter were within historically low values. Laboratory staff resampled at approximately 1250 p.m. and the reanalysis yielded sample and duplicate results of 0.6 mL/L and 0.7 mL/L (or an average of 0.65 mL/L). The settleable solids measurement is, therefore, not deemed indicative of the treatment performance of the plant, but rather is associated with a likely flow disturbance to the plant on this particular day at the time of sample collection |

Salinity is calculated by the laboratory based on the conductivity and temperature of a sample. Results for Salinity could not be calculated for the weekly effluent samples collected on 11/17/2022 and 11/21/2022 due to missing temperature values of the samples during the conductivity analysis. |
The Conductivity analytical batch 22326CON80 analyzed on 11/22/2022 with both the 11/17/22 and 11/21/22 effluent samples was reported without the sample temperature values. This was discovered to be due to the loss of connection for unknown reasons between the daily bench PC and the Winwedge software, which automatically uploads the data from the conductivity meter to the bench PC. The issue was not determined quickly enough, and the samples were already discarded, so reanalysis was not possible. Because salinity is a new monitoring parameter for the facility, the requirement was not yet fully entrenched in the lab analysts. The supervisor worked to restore the connection and reminded the analysts to make sure that temperature is recorded and/or available for every conductivity value. Further, the supervisor initiated a Corrective Action Report (CAR # 18196) to document and prevent recurrence of this event. |

There is deficient monitoring due to the unavailability of the November monthly influent and effluent radioactivity results for this month's reporting. |
The November monthly influent and effluent samples for radioactivity analysis were collected per the permit-prescribed sampling frequency and were promptly outsourced to an external laboratory; however, the external laboratory report has not been received by the City in-house laboratory to date. Per the external laboratory, results will be sent as soon as possible; unfortunately, data will not meet the reporting deadline. The monitoring result for radioactivity analysis will be reported in CIWQS as soon as the external lab report is received. The City of San Diego in-house laboratory has started to look into outsourcing permit-required radiation samples to other external laboratories. |

Ammonia was not analyzed on the weekly influent samples collected on 10/24/2022.
The laboratory updated the Point Loma sampling routine with the additional parameter requirements as soon as the permit amendment became effective on 9/25/2022. However, during this Sample Control update to include the add-on influent nutrients monitoring, the influent ammonia parameter was inadvertently changed from weekly to quarterly frequency as aligned with the other nitrogen species. |
Lab supervisors and staff have been reminded to increase communication when samples anticipated for permit monitoring analysis are missing. While lab analysts are expected to be cognizant of the frequency requirements in their assigned analysis and are consistently and promptly informed of regulatory changes, lab supervisors will also provide supplemental group training to reinforce awareness of permit requirements. An additional supervisor position has also been requested by the laboratory for increased oversight to sample control activities. |
