CAT1 |
Nitrogen, Total (as N) Other limit is 10 mg/L and reported value was 34 mg/L at REC-003. |
IRWD currently operates under a total nitrogen and total phosphorus offset program that mitigates the overall impact of the total nitrogen that enters the watershed. Credits generated through the established natural treatment systems and used to offset these results are reported in the annual summary report submitted April 1st of each year. IRWD submitted the plan in December 2018 and is waiting on the approval of the RWQCB. |

OEV |
Total Coliform Not to exceed a specific limit more than once within any 30-day period. limit is 23 MPN/100 mL and reported value was 49 MPN/100 mL at REC-003. |
Water Recycling Operations determined the LAFE_G final effluent sampling tap to be the source of the elevated total coliforms. This was determined through the sampling and data results process that showed a decrease in the coliform results once the tap was cleaned and disinfected. IRWD staff does not believe that the final effluent posed any risk to public health or the environment. As a precaution, Water Recycling Operations halted and diverted flows until Total Coliform sample confirmations were available indicating the disinfection was effective at targeting the source. As a corrective action, Water Recycling Operations has outlined procedures to expedite the course of action for presumptive results and to better identify if the sample tap as the source of high values. These procedures include Water Recycling Operations staff performing sample tap cleaning and coordinate follow-up sampling should there be a need to confirm elevated Total Coliform results within the first 24-hour window after an elevated presumptive result is received. |
