This is a rebuild of Drinking Water Watch and not yet the official record. Use the agency’s current Drinking Water Watch for anything you need to rely on.
Level Type
From the help published with Drinking Water Watch 3.5, reproduced as delivered.
Level Type can be either MDL (i.e., the laboratory reported the analytical result was
less than the Method Detection Limit) or MRL (i.e., the laboratory reported the
analytical result was less than the Minimum Reporting Level).
