Glossary:
Level Found - The highest level of each substance detected at or above the MRL* in representative finished product samples.
** MCL - Maximum Contaminant Level. The highest level of a substance allowed by law in drinking water (bottled or tap water). The MCLs shown are the federal MCLs set by the U.S. Environmental Protection Agency and the Food and Drug Administration, unless no federal MCL exists.
†Where no federal MCL exists, the MCLs shown are the California MCLs set by the California Department of Health Services. California MCLs are identified with an (†).
MFL - Million Fibers per Liter.
* MRL - Minimum Reporting Limit. Where available, MRLs reflect the Method Detection Limits (MDLs) set by the U.S. Environmental Protection Agency or the Detection Limits for Purposes of Reporting (DLRs) set by the California Department of Health Services. These values are set by the agencies to reflect the lowest concentration of each substance that can be accurately quantified by applicable testing methods, and are also the minimum reporting thresholds applicable to the Consumer Confidence Reports produced by tap water suppliers.
ND - Not detected at or above the MRL.
ppb - Parts per Billion. Equivalent to micrograms per liter (μg/l).
NR - Not listed in State or Federal drinking water regulations.
NA - Not applicable to specific test method or test parameter.
