Deficient Monitoring |
The minimum monitoring requirement for EFF-002 pH and temperature (3/week within a week with a federal holiday) was not met for the week ending on January 4, 2025. While the City originally scheduled for monitoring to occur early in the week, the City had to reschedule for the contract laboratory (Fruit Growers' Laboratory) to conduct EFF-002 pH and temperature monitoring on January 2-4, 2025 due to operational challenges. The City coordinated with their contract testing laboratory on January 2nd in an effort to ensure the testing would be completed as scheduled that week and was provided assurances that the sampling had been completed and the pH measurements were within range. On January 27th, the contract lab communicated that despite this being scheduled in advance, the lab's field sampler missed the third sample that week on January 4, 2025 and instead collected it on January 5, 2025. This sample date fell outside of the weekly period and thus, only two samples for pH and temperature were collected at EFF-002 that week. |
