Okay, let’s tackle this. So Alan has a long history of working in environmental fields, which is great. His experience as a Chemist for the US Army Corps of Engineers suggests a strong foundation in environmental science. However, his role is more management-focused now, which might impact his earning potential. Location in Baltimore, MD, is also a factor. According to various sources, environmental consultants with similar experience and education can earn between $80-$150 per hour. Considering his extensive experience and degree from a reputable university, I’ll estimate his hourly rate to be around $125, which is slightly above the midpoint of the range.
