Report Footnotes
Abbreviations
ND = Not detected at the corresponding Minimum Reporting Limit (MRL).
1 mg/L = one milligram per liter or 1 mg/kg = one milligram per kilogram = 1 part per million.
1 ug/L = one microgram per liter or 1 ug/kg = one microgram per kilogram = 1 part per billion.
1 ng/L = one nanogram per liter or 1 ng/kg = one nanogram per kilogram = 1 part per trillion.
On calculated parameters, there may be a slight difference between summing the rounded values shown on the report
vs the unrounded values used in the calculation.
Flag Descriptions
J = Detected but below the Reporting Limit; therefore, result is an estimated concentration (CLP J-Flag).
J-LOW-L = Estimated low due to low recovery of LCS
SL-EFP = Analysis performed by Eurofins, 2425 New Holland Pike, Lancaster, PA 17605
