The extreme sensitivity required for direct observation of gravitationalwaves by the Advanced LIGO detectors means that environmental noise canpotentially contaminate gravitational wave signals. Consequently, environmentalmonitoring efforts have been undertaken and novel noise mitigation techniqueshave been developed which have helped keep environmental artifacts frominfluencing gravitational wave detections for the $90$ gravitational waveevents detected from 2015--2020 by the aLIGO detectors. The increasing rate ofgravitational wave detections due to detector sensitivity improvements requiressophisticated, reliable and automated ways to monitor and assess the degree ofenvironmental coupling between gravitational wave detectors and theirsurroundings. We introduce a computational tool, PEMcheck, for quantifying thedegree of environmental coupling present in gravitational wave signals usingdata from the network of environmental monitoring sensors. We study itsperformance when applied to the $79$ gravitational waves confidently detectedin LIGO's third observing run and test its performance in the case of extremeenvironmental contamination of gravitational wave data. We find that PEMcheck'sautomated analysis identifies only a small number of gravitational waves thatmerit further study by environmental noise experts due to possiblecontamination, a substantial improvement over the manual vetting that occurredfor every gravitational wave candidate in previous observing runs. Overall,PEMcheck works as intended. Consequently, PEMcheck will play a critical role inevent validation during LIGO's fourth observing run.
