Sodium, % Annual Average (Mean) limit is 60 % and reported value was 61 %. |
EWA will continue to monitor percent sodium on a monthly basis per the CWRF Permit R9-2016-0183. We have attached a study of the mineral content of local drinking water agencies that was conducted from 2018-2020. We have also included a study of the mineral components of the percent sodium calculation. The sodium percentage appears to increase when the percent magnesium, calcium and potassium decrease. |

08/01/2022 |
Order Conditions |
Spilled 25 gallons of TWAS/primary sludge; recovered 25 gallons.
The liquid/ condensate seperator that supplies Digester #5 TWAS and Primary feed valves failed. These two feed valves, which opereate off of a temporary flexible air line, failed in an open positiom due to a loss in pressure. There were multiple bleed offs on the Digester #5 manifold that were open causing TWAS and Primary Sludge to spill out. |
All sludge was contained and hosed to the digester drainage pit. A work order was generated to add additional isolation valves on either side of the TWAS and Primary Sludge feed valves. Additionally, a work order has been generated to repair the (sun worn) temporary flexible air line that is supplying the two valves in order to prevent failure. |
