About this file

Written by GovTribe AI ·

This document contains two laboratory test reports from the Sacramento Area Sewer District's Environmental Laboratory for the Arden Park Vista water system. The reports detail chlorine residual and total coliform/E. coli test results conducted on multiple water sampling sites between December 2, 2024, and December 31, 2024. The chlorine residual tests, performed using the DPD Colorimetric Method, show free chlorine residual levels ranging from 1.15 to 1.60 mg/L at various locations including Los Alamos Tank, 1919 Spanos Court, Oak Meadow Park, 3406 Clemens Way, 3819 Esperanza Drive, and 4204 Corona Way.

The total coliform and E. coli tests, performed using the Colilert Presence/Absence method per 100 mL sample, consistently show "Absent" results for both total coliform and E. coli across all sampling dates and locations. The tests were conducted by analysts with the initials LLC and ME, with analysis dates typically occurring on the same day as sample collection. These reports are part of the Sacramento County Water Agency's water quality monitoring program, ensuring compliance with California Domestic Water Quality and Monitoring Regulations and US EPA Potable Water Well Testing Requirements.
