Specialized Hydrogeology and Environmental Consulting Since 1976

Meiser & Earl, Inc brings more than five decades of focused hydrogeology and environmental consulting experience to clients throughout Pennsylvania. We help property owners, developers, and organizations understand and solve complex subsurface water issues, site conditions, and regulatory requirements with thorough analysis and clear recommendations.

Our veteran-owned, woman-owned, and locally operated practice operates one of the oldest consulting offices in Pennsylvania. We combine over 150 years of collective professional experience with personalized service that gives each project the attention it deserves. We provide detailed proposals rather than basic estimates, and most initial consultations come at no charge. Contact us to discuss your environmental or hydrogeologic needs.
