Mr. Uhl began his career in water supply development and management in Central India where he initiated a water development project for the Lutheran Church at the age of 25. This project evolved into an organization with over 50 employees and provided a full service approach to water supply development from the siting of production wells utilizing geophysics and remote sensing applications to well repairs and drinking water quality evaluation. The project installed over 3,000 wells in the hard rock regions of central and southern India and provided a training ground for other projects in the region including UNICEF - WES.

Since that time, Mr. Uhl has specialized in the exploration, development, protection and management of water resources for public, industrial and agricultural uses and in the investigation and remediation of soil, groundwater, and surface water contamination incidence. He has investigated and characterized hundreds of industrial sites, large municipal landfills, interstate petroleum and gas pipelines and formulated monitoring and remedial strategies with regulatory authorities. While with Geraghty & Miller, Inc. he led a 2-year project that culminated in the preparation of the Underground Injection Control (UIC) regulations for the United States Environmental Protection Agency.

At Malcolm Pirnie, Inc., an international civil engineering firm, he managed the firm’s Groundwater Group. In 1984, he opened and managed a New Jersey office for Geraghty & Miller, Inc., a highly respected groundwater and environmental engineering consulting firm. In 1991, he started his own consulting practice that provides water and environmental consulting to industry, municipalities, international governments, consulting firms and legal clients on all projects with water and/or environmental components. He has worked extensively in the United States, southern and eastern Africa, the Philippines, and India, and in 10 other countries on short-term assignments. He has managed and directed many large water-supply development, management, planning, and protection projects in the United States and abroad.

He has a seasoned, field-based background that is invaluable for detailed analysis of groundwater systems as a basis for sustainability/recharge evaluations and optimal groundwater systems management. Mr. Uhl has taught graduate level courses in Hydrogeology at the University of Maryland, the University of Akola in India, and at the New Jersey Institute of Technology in Newark, New Jersey. He has given many presentations at seminars, international conferences, universities, and for corporate forums.



Mr. Uhl has a range of experience in water development that covers the initial phase of project development through final analysis of resource sustainability, development alternatives, and groundwater systems installation and commissioning.  He has directed projects over large study areas and in complex hydrologic and hydrogeologic settings.  He has particular experience in practical applications including appropriate drilling techniques for unconsolidated and bedrock conditions, test and production well design, test drilling, production well drilling and aquifer testing programs.  He has been involved with the design and installation of many hundreds of production wells (up to 1000 meters deep) and aquifer pumping tests in all types of hydrogeologic settings. 

He is currently managing water development projects for large groundwater based municipal utilities and international clients.  These projects address basic and complex water issues such as protection, management, new source development and sustainability.  He has had the opportunity overseas to work in unexplored areas and in large scale multi-disciplinary water resource evaluation and planning projects.

Vincent Uhl has provided services to several New Jersey Groundwater Utilities in the area of land use planning in critical watersheds.

bulletMontville Township

Montville Township derives its’ drinking water supply from 3 high capacity production wells completed in the Towaco Valley Aquifer.  The Towaco basin is a 4.4 mi2 drainage basin with a safe yield of 2 million gallons per day.  A sustainability assessment conducted by Uhl in 1998 indicated that the Towaco Valley Aquifer receives 1/3 of its recharge from induced infiltration of surface water thus rendering this glacial aquifer system quite sensitive to land use practices in the drainage basin.  Uhl has and continues to provide professional hydrogeologic services to the Township’s water utility, land use planning department and environmental commission in the following areas:

  • Review of development plans for proposed construction in the Towaco Valley basin for consistency with the Township’s objective of preserving the quality and quantity of this sole source aquifer.  Uhl has reviewed approximately five plans with respect to their impact on groundwater recharge and has negotiated with the developers to institute best management practices in this regard including protecting stream and wetland areas, management of storm water, and roof drain water.
  • Modeling of well head protection zones for the Township’s production wells.
  • Preparation of a draft Municipal Ordinance for Well Head Protection for the Township.  This was prepared based on current land uses within the Well Head Protection Zones and a critical review of available draft and final documents drawn up by other New Jersey municipalities and counties.
  • Evaluation of the impact of historical land use at an orchard with residual pesticides and metals in soil on the quality of groundwater and surface water in the watershed.

bulletCity of East Orange

The City of East Orange derives its public water supply from a 2,300 acre water reserve located in Millburn, Livingston and Florham Park, New Jersey.  The water reserve contains 4 wellfields with 18 production wells.  As the Water Commission’s hydrogeologist, Vincent Uhl has reviewed and critiqued plans for:

  • A proposed highway across the wellfield area; due in part to Mr. Uhl’s efforts, the highway was never built.
  • A proposed development within two wellfield areas.
  • Uhl has recently evaluated wellfield conditions (well yield and efficiency, water level and water quality history) over the past 15 years and current land uses within the wellfield’s watersheds.  Uhl provided recommendations to the East Orange Water Commission as to future land use protection measures that should be implemented to protect the quality and quantity of the groundwater resource in the reserve.
