About this file

This is a Certificate of Analysis water test report issued by Advanced Environmental Laboratories, Inc. to US Water Drinking Water for Anthony Elementary School in Marion County, Florida. The report documents drinking water sample analysis collected on April 29, 2025, from the kitchen tap location (ANTHONY-KITCHEN) at the school. The laboratory analysis was conducted pursuant to workorder G2504319 and completed on May 13, 2025, in accordance with NELAC standards and Florida Department of Environmental Protection regulations under Chapter 62-550, F.A.C. The samples were analyzed using multiple EPA and Standard Methods protocols, including EPA 200.7 for metals, EPA 300.0 for anions, and various Standard Methods for hardness, total dissolved solids, and pH measurements. The report indicates that all analytical data met NELAC requirements and were certified by Project Manager Madeline Lynch of Advanced Environmental Laboratories, Inc., which maintains current Florida DOH certification E82001 valid through June 30, 2025.

The analytical results detailed in this report directly support the Marion County School Board's Water Softeners for Food Services contract opportunity, which requires the awarded vendor to conduct monthly water sampling and analysis at twelve school cafeteria locations for twelve months following installation of water softening equipment. This water test from Anthony Elementary represents baseline or post-installation data establishing the water quality conditions at one of the contract sites. The results conform to all applicable compliance requirements and provide the documented water analysis that the vendor must deliver as part of the contract deliverables to demonstrate the effectiveness of the water softening systems in reducing hardness and other water quality parameters at the school district's food service locations.
