EarthRes

What EarthRes does

EARTHRES Group, Inc. is a multi-disciplinary engineering and environmental consulting firm founded in 1995 and headquartered in Pipersville, Pennsylvania. The company delivers design, permitting, construction quality assurance, and operational support across four regulated-industry verticals: Mining, Energy, Solid Waste, and Environmental compliance. Services span civil, mechanical, electrical, geological, and environmental engineering, organized into eight integrated service lines — Solid Waste, Mining, Energy, Environmental Permitting and Compliance, Civil/Survey/Construction Support, Mechanical/Electrical Controls/Process Design, Geology/Hydrogeology, and Field Services — that allow the firm to bundle multi-discipline work for clients from initial exploration and planning through design, permitting, construction support, and ongoing operations.

The firm operates as a project-based B2B professional-services business, engaging enterprise and government clients through direct sales relationships. Technical capabilities rely on industry-standard engineering software (AutoCAD Plant 3D, Civil 3D, HYSYS, GASWorkS, GMS MODFLOW, MT3DMS, AERMOD, SCADA) combined with proprietary expertise in groundwater modeling (20+ years), FAA Part 107-certified aerial and ground surveying (drones, Leica CS20 SmartNet GPS, 3D laser scanning, bathymetric equipment), NACE-certified cathodic protection, and GIS mapping. Named engagements include Southern Nevada Water Authority's Lake Mead low-lake-level pumping program (designed to enable 900 million gallons/day of water delivery), a 10 MW landfill gas-to-energy plant that earned U.S. EPA LMOP Project of the Year ($9.2M total project, 4,200 scfm capacity), and an international pilot project in Zacatecas, Mexico capturing 5.75 million cubic meters of methane annually.

In 2024, EARTHRES was acquired by RESPEC and now operates as "EARTHRES | A Division of RESPEC," retaining its brand identity while gaining access to RESPEC's broader resources. The firm operates from three U.S. locations — Pipersville PA (HQ), Morgantown WV (Appalachian regional office), and Central City PA (Central Pennsylvania subsidiary) — and serves Mid-Atlantic, New England, Appalachian, Southeast, and Southwest U.S. regions, with selected international work in Mexico. Founder Jan Hutwelker, PE remains as President/CEO, leading a roster of professional engineers (PE), geologists (PG), and certified specialists.
