Deficient Monitoring |
On January 16, 2024, the City of Corona was notified by the contract laboratory, Eurofins, that the WRF No. 1 total coliform sample, collected on January 10th, did not meet the 48-hour incubation requirement due to laboratory error. During the transfer to the confirmation phase, the transferred samples were not incubated, rendering unreportable results. This was an error by the analyst, where they switched the prior day's completed samples with the January 10th samples by accident. |
