Brandon Fleming
I've been a hydrologist with USGS since 2008 and currently serve as the Pennsylvania Water Science Center Groundwater Specialist. My work has focused on characterizing fractured rock and porous media aquifers, groundwater/surface water relations, groundwater ages, and understanding spatial and temporal variability of groundwater quality.

Science and Products
Groundwater Recharge - Pennsylvania
Recharge is the process of adding water to the saturated zone. Because it is almost impossible to measure directly, recharge is usually estimated by indirect means.
Groundwater Availability and Use
The USGS Pennsylvania Water Science Center helps water providers assess the availability of groundwater for use in homes, on farms, and in industrial activities.
Pennsylvania Drought Condition Monitoring
The Pennsylvania Department of Environmental Protection relies upon a number of parameters to monitor water-supply-drought conditions, among which are four parameters displayed herein—precipitation, streamflow, groundwater levels, and the Palmer Drought Severity Index, an indicator of soil moisture dryness.

Groundwater Monitoring and Tools for Pennsylvania
Groundwater-quality data from the National Water-Quality Assessment Project, January through December 2014 and select quality-control data from May 2012 through December 2014
Groundwater-quality data were collected from 559 wells as part of the National Water-Quality Assessment Project of the U.S. Geological Survey National Water-Quality Program from January through December 2014. The data were collected from four types of well networks: principal aquifer study networks, which are used to assess the quality of...

Water quality in the surficial aquifer near agricultural areas in the Delaware Coastal Plain, 2014
The U.S. Geological Survey, in cooperation with the Delaware Department of Agriculture, developed a network of wells to monitor groundwater quality in the surficial aquifer of the Delaware Coastal Plain. Well-drained soils, a flat landscape, and accessible water in the Delaware Coastal Plain make for a productive agricultural setting. As such,...

Statistical classification of hydrogeologic regions in the fractured rock area of Maryland and parts of the District of Columbia, Virginia, West Virginia, Pennsylvania, and Delaware
Hydrogeologic regions in the fractured rock area of Maryland were classified using geographic information system tools with principal components and cluster analyses. A study area consisting of the 8-digit Hydrologic Unit Code (HUC) watersheds with rivers that flow through the fractured rock area of Maryland and bounded by the Fall Line was...

A science plan for a comprehensive assessment of water supply in the region underlain by fractured rock in Maryland
The fractured rock region of Maryland, which includes land areas north and west of the Interstate 95 corridor, is the source of water supply for approximately 4.4 million Marylanders, or approximately 76 percent of the State's population. Whereas hundreds of thousands of residents rely on wells (both domestic and community), millions rely on...

Geology, Hydrology, and Water Quality of the Little Blackwater River Watershed, Dorchester County, Maryland, 2006-09
The Little Blackwater River watershed is a low-lying tidal watershed in Dorchester County, Maryland. The potential exists for increased residential development in a mostly agricultural watershed that drains into the Blackwater National Wildlife Refuge. Groundwater and surface-water levels were collected along with water-quality samples to document...

Simulation of groundwater flow to assess future withdrawals associated with Base Realignment and Closure (BRAC) at Fort George G. Meade, Maryland
Increased groundwater withdrawals from confined aquifers in the Maryland Coastal Plain to supply anticipated growth at Fort George G. Meade (Fort Meade) and surrounding areas resulting from the Department of Defense Base Realignment and Closure Program may have adverse effects in the outcrop or near-outcrop areas. Specifically, increased pumping...

Implications of anthropogenic river stage fluctuations on mass transport in a valley fill aquifer
In humid regions a strong coupling between surface water features and groundwater systems may exist. In these environments the exchange of water and solute depends primarily on the hydraulic gradient between the reservoirs. We hypothesize that daily changes in river stage associated with anthropogenic water releases (such as those from a...

Drought Watch or Warning Removed from 20 Pennsylvania Counties, Drought Watch Remains in 3 Counties
USGS groundwater and surface water monitoring data contributed to the January 7, 2021 removal of drought watch or warning declarations for 20 counties by the Pennsylvania Department of Environmental Protection (PaDEP).
On January 7, 2021, PaDEP removed drought watch or warning in 20 counties and maintained drought watch status for 3 counties.
Drought Watch Reduced to 20 Pennsylvania Counties, Drought Warning Continues in 3 Counties
USGS groundwater and surface water monitoring data contributed to the August 21, 2020 drought watch declaration for 16 counties by the Pennsylvania Department of Environmental Protection (PaDEP). The last drought watch...
