1124133 11/07/2023 Deficient Monitoring Nitrate+Nitrite and Nitrite samples were collected on 11/7/2023. The Nitrite sample experienced a QC failure and was resampled on 11/14/2023. The lab forgot to resample for Nitrate+Nitrite as well as Nitrite so Nitrate+Nitrate was analyzed from the 11/7/2023 sample while Nitrite was analyzed from the 11/14/2023 sample. Due to this, Nitrate was unable to be calculated from the two results since they weren't from the same day. Violation N eSMR Tapia WRF 413302 R4-2017-0124 N
