< 4.0 < 4.0

Analyte is not certified or the state of the samples origination does not offer certification for the Analyte.

MCL

The Maximum Contaminant Level (MCL) is the maximum concentration of a chemical that is allowed in public drinking water systems. The MCL is established by the U.S. Environmental Protection Agency (EPA). Some states have MCLs that are equal to or less than the Federally established MCL. The listed MCL value reflects the MCL established by the State where the sample was taken.

General Notes for N5G0643

The RLs and MDLs (Reporting Limit and Method Detection Limit respectively) reported are adjusted for any dilution necessary due to the levels of target and/or non-target analytes and matrix interference. The RL(REPORTING LIMIT) is based upon the lowest standard utilized for the calibration where applicable.
Samples are retained for a period of thirty days after submittal of report, unless other arrangements are made.
York's liability for the above data is limited to the dollar value paid to York for the referenced project.
This report shall not be reproduced without the written approval of York Analytical Laboratories, Inc.
All analyses conducted met method or Laboratory SOP requirements. See the Sample and Data Qualifiers Section for further information.
It is noted that no analyses reported herein were subcontracted to another laboratory, unless noted in the report.
This report reflects results that relate only to the samples submitted on the attached chain-of-custody form(s) received by York.
