Bruce Lindsey
Bruce Lindsey is a hydrologist with the USGS Water Resources Mission Area.
Bruce Lindsey has worked as a hydrologist with the U.S. Geological Survey since 1992. His primary field of interest is groundwater quality. He has conducted regional and national assessments of status and trends in groundwater quality in the United States for the National Water-Quality Assessment project. He currently is the coordinator of groundwater assessments for the National Water Quality Network, which monitors groundwater quality in about 2,200 wells across the United States in 82 networks of about 25-30 wells each. The objective of this study is to evaluate the quality and availability of groundwater for drinking supply, improve our understanding of where and why water quality is degraded, and assess how groundwater quality could respond to changes in hydrologic conditions and land use. Constituents of concern for this research include both natural contaminants (trace elements and radionuclides) as well as anthropogenic contaminants (nutrients, per- and polyfluoroalkyl substances (PFAS), volatile organic compounds and pesticides). Bruce is also the project manager for the National Surveillance function, which evaluates and summarizes substantial issues potentially affecting water availability – streamflow, groundwater levels, surface water quality, and groundwater quality – from USGS national networks. In addition, Bruce has also conducted studies on microbiological quality of drinking water resources, focusing on occurrence of both bacteria and viruses.

The quality of our nation's waters: water quality in the Principal Aquifers of the Piedmont, Blue Ridge, and Valley and Ridge regions, eastern United States, 1993-2009
The aquifers of the Piedmont, Blue Ridge, and Valley and Ridge regions underlie an area with a population of more than 40 million people in 10 states. The suburban and rural population is large, growing rapidly, and increasingly dependent on groundwater as a source of supply, with more than 550 million gallons per day withdrawn from domestic wells for household use. Water from some of these aquife

Pesticides in groundwater of the United States: decadal-scale changes, 1993-2011
The national occurrence of 83 pesticide compounds in groundwater of the United States and decadal-scale changes in concentrations for 35 compounds were assessed for the 20-year period from 1993–2011. Samples were collected from 1271 wells in 58 nationally distributed well networks. Networks consisted of shallow (mostly monitoring) wells in agricultural and urban land-use areas and deeper (mostly d

Factors affecting temporal variability of arsenic in groundwater used for drinking water supply in the United States
The occurrence of arsenic in groundwater is a recognized environmental hazard with worldwide importance and much effort has been focused on surveying and predicting where arsenic occurs. Temporal variability is one aspect of this environmental hazard that has until recently received less attention than other aspects. For this study, we analyzed 1245 wells with two samples per well. We suggest that

Trends in groundwater quality in principal aquifers of the United States, 1988-2012
The U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program analyzed trends in groundwater quality throughout the nation for the sampling period of 1988-2012. Trends were determined for networks (sets of wells routinely monitored by the USGS) for a subset of constituents by statistical analysis of paired water-quality measurements collected on a near-decadal time scale.

Methods for evaluating temporal groundwater quality data and results of decadal-scale changes in chloride, dissolved solids, and nitrate concentrations in groundwater in the United States, 1988-2010
Decadal-scale changes in groundwater quality were evaluated by the U.S. Geological Survey National Water-Quality Assessment (NAWQA) Program. Samples of groundwater collected from wells during 1988-2000 - a first sampling event representing the decade ending the 20th century - were compared on a pair-wise basis to samples from the same wells collected during 2001-2010 - a second sampling event repr

Quality of major ion and total dissolved solids data from groundwater sampled by the National Water-Quality Assessment Program, 1992–2010
Proper interpretation of water quality requires consideration of the effects that contamination bias and sampling variability might have on measured analyte concentrations. The effect of contamination bias and sampling variability on major ion and total dissolved solids data in water samples collected in 48 of the 52 National Water-Quality Assessment Program study units from 1992–2010 is discussed

Factors affecting groundwater quality in the Valley and Ridge aquifers, eastern United States, 1993-2002
Chemical and microbiological analyses of water from 230 wells and 35 springs in the Valley and Ridge Physiographic Province, sampled between 1993 and 2002, indicated that bedrock type (carbonate or siliciclastic rock) and land use were dominant factors influencing groundwater quality across a region extending from northwestern Georgia to New Jersey. The analyses included naturally occurring compou

Contributions of Phosphorus from Groundwater to Streams in the Piedmont, Blue Ridge, and Valley and Ridge Physiographic Provinces, Eastern United States
Phosphorus from natural and human sources is likely to be discharged from groundwater to streams in certain geochemical environments.

Relations between sinkhole density and anthropogenic contaminants in selected carbonate aquifers in the eastern United States
The relation between sinkhole density and water quality was investigated in seven selected carbonate aquifers in the eastern United States. Sinkhole density for these aquifers was grouped into high (>25 sinkholes/100 km2), medium (1–25 sinkholes/100 km2), or low (<1 sinkhole/100 km2) categories using a geographical information system that included four independent databases covering parts of Alaba
