Matthew K Landon
Matthew Landon has been a Hydrologist with the U.S. Geological Survey since 1990.
He received a M.S. in Geology from the University of Minnesota in 1993 and a B.S. in Geology from the University of Kansas in 1987. He has conducted studies of groundwater hydrology and geochemistry in Minnesota, Nebraska, California, and Southeast Asia. He has been with the USGS California Water Science Center in San Diego since 2005, serving as Program Chief for the Groundwater and Geochemistry Projects Group from 2012-2016 and the California Oil, Gas, and Groundwater Projects Group since 2016.

Simulations of Ground-Water Flow, Transport, Age, and Particle Tracking near York, Nebraska, for a Study of Transport of Anthropogenic and Natural Contaminants (TANC) to Public-Supply Wells Simulations of Ground-Water Flow, Transport, Age, and Particle Tracking near York, Nebraska, for a Study of Transport of Anthropogenic and Natural Contaminants (TANC) to Public-Supply Wells
Contamination of public-supply wells has resulted in public-health threats and negative economic effects for communities that must treat contaminated water or find alternative water supplies. To investigate factors controlling vulnerability of public-supply wells to anthropogenic and natural contaminants using consistent and systematic data collected in a variety of principal aquifer...

Ground-water quality data in the Central Eastside San Joaquin Basin 2006: Results from the California GAMA program Ground-water quality data in the Central Eastside San Joaquin Basin 2006: Results from the California GAMA program
Ground-water quality in the approximately 1,695-square-mile Central Eastside study unit (CESJO) was investigated from March through June 2006 as part of the Statewide Basin Assessment Project of the Groundwater Ambient Monitoring and Assessment (GAMA) Program. The GAMA Statewide Basin Assessment project was developed in response to the Groundwater Quality Monitoring Act of 2001 and is...

Low-Level detections of halogenated volatile organic compounds in groundwater: Use in vulnerability assessments Low-Level detections of halogenated volatile organic compounds in groundwater: Use in vulnerability assessments
Concentrations of halogenated volatile organic compounds (VOCs) were determined by gas chromatography (GC) with an electron-capture detector (GC-ECD) and by gas chromatography with mass spectrometry (GC-MS) in 109 groundwater samples from five study areas in the United States. In each case, the untreated water sample was used for drinking-water purposes or was from a monitoring well in...

Source and transport controls on the movement of nitrate to public supply wells in selected principal aquifers of the United States Source and transport controls on the movement of nitrate to public supply wells in selected principal aquifers of the United States
In 2003–2005, systematic studies in four contrasting hydrogeologic settings were undertaken to improve understanding of source and transport controls on nitrate movement to public supply wells (PSW) in principal aquifers of the United States. Chemical, isotopic, and age tracer data show that agricultural fertilizers and urban septic leachate were the primary sources of large nitrate...

Ground-water age and quality in the High Plains Aquifer near Seward, Nebraska, 2003-04 Ground-water age and quality in the High Plains Aquifer near Seward, Nebraska, 2003-04
The U.S. Geological Survey, in cooperation with the City of Seward, Nebraska, conducted a study of ground-water age and quality to improve understanding of: (1) traveltimes from recharge areas to public-supply wells, (2) the effects of geochemical reactions in the aquifer on water quality, and (3) how water quality has changed historically in response to land-use practices. Samples were...
