| Details: | 1-12-26 Update - Public notice received. 1-9-26 Update - a public notice template was sent to Nathan Frarck that included not meeting CT or 0.2 mg/l entry point residual requirement in December 2025 and the November 2025 lead and copper excursions (see contact report dated 1-6-26). 1-8-26 - I spoke to Nathan Frarck who let me know that they did not meet disinfection requirements in December 2025. In December 2025, the free chlorine residual dropped below the minimum required level of 0.2 mg/l at the entry point to the distribution on December 27th, 28th, and 29th. During this time the chlorine residual ranged from 0.3 mg/l on December 27th, 0.35 mg/l on December 28th, and 0.02 mg/l on December 29th (the lowest level for the month). The free chlorine residual was subsequently restored to meet all disinfection requirements on December 30th,2025, with a free chlorine residual of 1.92 mg/l. City staff believe the issue resulted from a malfunctioning chlorine analyzer, which mis-read the actual residual level of chlorine. Operators sampled the treated water to confirm that disinfection was occurring but did not document the results. On January 11th, the chlorine residual was noticed by consumers as it was turned a bit higher than normal to correct for a low reading from this malfunctioning analyzer. While higher than normal, chlorine levels remained within safe levels. The issue with the analyzer has been corrected. | ||
