RL – Reporting Level means the level to which the laboratory reported the presence of an analyte. For radionuclides, Reporting Level is the MDA95.

DLR – Detection Limit for purposes of Reporting (DLR) means the designated minimum level at or above which any analytical finding of a contaminant in drinking water resulting from monitoring required under Chapter 15 of Title 22 shall be reported to the State Board (California Code of Regulations Section § 64400.34)
