Specialized Hydrogeologic and Groundwater Services in Pennsylvania

Meiser & Earl, Inc has provided dedicated hydrogeologic consulting services throughout Pennsylvania since 1976. Our firm focuses exclusively on hydrogeology, bringing five decades of concentrated experience to every project. The team combines over 150 years of professional consulting experience with a personable, project-specific approach that sets us apart from larger, generalized environmental firms.

As a locally owned, veteran-owned, and woman-owned small company, we maintain membership in the Pennsylvania Council of Professional Geologists and the Chamber of Business & Industry of Centre County. Our consultations include detailed proposals rather than simple estimates, and most are conducted without a fee. Contact Meiser & Earl to discuss your hydrogeologic needs and learn how our specialized knowledge can benefit your project.
