About this file
This is a Certificate of Analysis from Minnesota Valley Testing Laboratories (MVTL) for water samples collected from cooling towers and chillers at the Charleston VA Medical Center for Venergy Group. The laboratory report documents Heterotrophic Plate Count (HPC) testing for six different water samples collected on July 22, 2025, with analysis completed on July 27, 2025. Each sample was collected by Bryan Williams and maintained at 2.9°C, received on ice.
The test results show Heterotrophic Plate Count levels ranging from 26 to 254 CFU/mL across the samples, with all results below the Secondary Maximum Contaminant Level (SMCL) of 500 CFU/mL. Sample locations included "TO CHILLER" (50 CFU/mL), "FROM CHILLER" (254 CFU/mL), and multiple cooling tower samples labeled COOLING TOWER 5-7, with counts of 26, 96, and 36 CFU/mL respectively. The analysis was performed using Standard Method 9215C and was approved by Brady Halvorson, Lab Supervisor, under Minnesota Department of Health Accreditation that conforms to current TNI standards.
