Staff Profiles

David L. Pielmeier, Senior Scientist and Operations Manager

Mr. Pielmeier is a Senior Scientist with Advanced Land and Water, Inc. (ALWI) and possesses ten years of water resource evaluation and permitting experience. He has completed successful hydrogeologic characterization projects throughout the Mid-Atlantic States.

On a daily basis, Mr. Pielmeier designs, coordinates and oversees soils and hydrogeologic mapping, test site selection, drilling programs and pumping tests. In the field, he personally performs geologic logging, slug testing, hydrologic data collection, infiltrometer testing and data-logging and sampling activities. In the office, he is responsible for liaison and coordination with clients and regulatory officials, data reduction, hydrogeologic analyses and technical report preparation.

Mr. Pielmeier's expertise in Geographic Information Systems (GIS) has supported its full integration in supporting ALWI work product and agency submittals. He personally built and refined ALWI GIS capabilities; consequent geo-referencing has made our permitting submittals more attractive and technically defensible.

Mr. Pielmeier's related responsibilities include the development, implementation, and management of systems for the collection, interpretation, and portrayal of multi-dimensional and multi-platform digital site data, including both analytical and numerical (i.e., MODFLOW) groundwater modeling. He also possesses a complete proficiency in the use of ArcView and ArcGIS, and differentially-correcting Global Positioning Systems (GPS).

Relevant Professional Experience

Hydrogeologic Management Assignments

Managed and co-authored $120,000 MDE contract for performing source water assessments and preparing wellhead protection plans for 266 transient, non-community groundwater supplies across central Maryland. Delineated wellhead protection areas, identified contamination sources, developed and managed spatial databases and developed management strategies to protect against future potability threats.
Performed single-and double-ring infiltrometer tests, long-term groundwater monitoring, mounding evaluations, nitrogen loading assessments, and hydrologic balance calculations to support groundwater discharge permitting in both fractured bedrock and coastal plain hydrologic settings.
Designed, performed and documented application of analytical and numerical groundwater flow models, executed within complex hydrogeologic settings, to predict a wide range of groundwater withdrawal and (treated effluent) wastewater discharge effects.
Provided technical and regulatory support for municipal annexation projects where groundwater capacity was an approval prerequisite. Specific tasks included siting, testing and evaluating prospective municipal supply wells. Assisted in the development, refinement and negotiation of those provisions of Developer Rights and Responsibility Agreements relating to groundwater supply capacity.
Co-authored Source Water Assessment and Wellhead Protection Plans for several Maryland municipalities. Delineated wellhead protection areas, inventoried point-source and non-point contamination threats, reviewed draft ordinances for conformity with MDE guidelines and overall defensibility, and assisted in development and implementation of public awareness of community outreach programs.

GIS Application to Water Resources

Used GIS to portray spatial relationships between topographic features, mapped soil series, existing and proposed disposal areas, excavation and infiltrometer test sites, and the results of groundwater mounding projections as digital water level contour maps.
Prepared GIS maps showing fracture traces and recommended drilling locations in support of state-funded hydrogeologic evaluations in support of small water systems throughout rural Pennsylvania.
Prepared GIS maps and interpretive cross-sections showing the results of groundwater flow models. Prepared illustrations of the potential for adverse well interference and water supply impacts in a confined, multi-layer coastal plain aquifer system.
Illustrated (with GIS) the availability and allocability of groundwater resources associated with the location of existing and proposed wells for public and private sector clients.
