Luminescent Dissolved Oxygen (LDO) - The LDO probe method is acceptable to DEP, providing that the calibration verification procedures and criteria in DEP SOPs FT 1000 and FT 1500 are strictly followed. The LDO may be used for all laboratory and field analyses for non-potable water compliance reporting, all ambient monitoring for surface water, groundwater, and wastewater, and all groundwater purge-stabilization measurements. The cited federal reference is ASTM D888-05, Standard Test Methods for Dissolved Oxygen in Water, Test Method C, Luminescence-based Sensor Procedure.
