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.

Preliminary groundwater salinity mapping near selected oil fields using historical water-sample data, central and southern California Preliminary groundwater salinity mapping near selected oil fields using historical water-sample data, central and southern California
The distribution of groundwater salinity was mapped for 31 oil fields and adjacent aquifers and summarized by 8 subregions across major oil-producing areas of central and southern California. The objectives of this study were to describe the distribution of groundwater near oil fields having total dissolved solids less than 10,000 milligrams per liter (mg/L) based on available data and...

Prioritization of oil and gas fields for regional groundwater monitoring based on a preliminary assessment of petroleum resource development and proximity to California’s groundwater resources Prioritization of oil and gas fields for regional groundwater monitoring based on a preliminary assessment of petroleum resource development and proximity to California’s groundwater resources
The California State Water Resources Control Board initiated a regional monitoring program in July 2015 to determine where and to what degree groundwater quality may be adversely impacted by oil and gas development activities. A key issue in the implementation of the regional groundwater monitoring program is that each year, detailed characterization work can be done in only a few of...

Tracing enhanced oil recovery signatures in casing gases from the Lost Hills oil field using noble gases Tracing enhanced oil recovery signatures in casing gases from the Lost Hills oil field using noble gases
Enhanced oil recovery (EOR) and hydraulic fracturing practices are commonly used methods to improve hydrocarbon extraction efficiency; however the environmental impacts of such practices remain poorly understood. EOR is particularly prevalent in oil fields throughout California where water resources are in high demand and disposal of high volumes of produced water may affect groundwater...

Origin of methane and sources of high concentrations in Los Angeles groundwater Origin of methane and sources of high concentrations in Los Angeles groundwater
In 2014, samples from 37 monitoring wells at 17 locations, within or near oil fields, and one site >5 km from oil fields, in the Los Angeles Basin, California, were analyzed for dissolved hydrocarbon gas isotopes and abundances. The wells sample a variety of depths of an aquifer system composed of unconsolidated and semiconsolidated sediments under various conditions of confinement...

Mapping protected groundwater adjacent to oil and gas fields, San Joaquin Valley, California Mapping protected groundwater adjacent to oil and gas fields, San Joaquin Valley, California
Airborne electromagnetic (AEM) surveys are a major component of a regional study of groundwater quality adjacent to oil and gas fields in the San Joaquin Valley of California, USA. AEM resistivity models are being used to delineate groundwater salinity in an effort to locate groundwater adjacent to oil and gas fields that could have future beneficial use. AEM models are also being used...

Triennial changes in groundwater quality in aquifers used for public supply in California: Utility as indicators of temporal trends Triennial changes in groundwater quality in aquifers used for public supply in California: Utility as indicators of temporal trends
From 2004 to 2011, the U.S. Geological Survey collected samples from 1686 wells across the State of California as part of the California State Water Resources Control Board’s Groundwater Ambient Monitoring and Assessment (GAMA) Priority Basin Project (PBP). From 2007 to 2013, 224 of these wells were resampled to assess temporal trends in water quality. The samples were analyzed for 216...
