Description: Most major pollution regulations rely on self-reported emissions data. This paper uses extensive U.S. water pollution discharges data to examine the accuracy of environmental self-monitoring. We apply Benford’s Law to seek statistical signatures of reporting anomalies. We seek statistical signatures of misreporting by exploiting the timing of external inspections. We explore the relationship between Clean Water Act self-reported water pollution discharges and ambient water quality data from the U.S.G.S. Preliminary results fail to uncover strong evidence of strategic misreporting.
