Joseph Ayotte
Joe Ayotte is a Supervisory Hydrologist in the New England Water Science Center
As the Hydrologic Interpretive Branch Chief, Joe leads a team of scientists that conduct multidisciplinary studies involving groundwater, surface water, and water quality at the USGS New England Water Science Center. The work is conducted with the support of Section Chiefs in the Hydrologic Interpretive Branch. He also serves on the New England Water Science Center’s Senior Management Team, assisting with the planning, direction, and administration of the Center. His areas of science expertise include hydrologic investigations of groundwater and surface water, water quality, and interdisciplinary studies involving human exposure to contaminants.

Arsenic in groundwater in eastern New England: Occurrence, controls, and human health implications Arsenic in groundwater in eastern New England: Occurrence, controls, and human health implications
In eastern New England, high concentrations (greater than 10 ??g/L) of arsenic occur in groundwater. Privately supplied drinking water from bedrock aquifers often has arsenic concentrations at levels of concern to human health, whereas drinking water from unconsolidated aquifers is least affected by arsenic contamination. Water from wells in metasedimentary bedrock units, primarily in...

This geographic information system (GIS) data layer shows the generalized lithologic and geochemical, termed lithogeochemical, character of near-surface bedrock in the New England Coastal Basin (NECB) study area of the U.S. Geological Survey's National Water Quality Assessment (NAWQA) Program. The area encompasses 23,000 square miles in western and central Maine, eastern Massachusetts...

Shallow ground-water quality in the Boston, Massachusetts metropolitan area Shallow ground-water quality in the Boston, Massachusetts metropolitan area
Analyses of water samples collected from 29 wells across the Boston metropolitan area indicate that shallow ground water in recently urbanized settings often contains trace amounts of nutrients, fuel, and industrial-based organic compounds. Most of the samples that contained detectable amounts of organic compounds also had elevated levels of iron and total dissolved solids. Nitrate was...

Relation of arsenic, iron, and manganese in ground water to aquifer type, bedrock lithogeochemistry, and land use in the New England coastal basins Relation of arsenic, iron, and manganese in ground water to aquifer type, bedrock lithogeochemistry, and land use in the New England coastal basins
In a study of arsenic concentrations in public-supply wells in the New England Coastal Basins, concentrations at or above 0.005 mg/L (milligrams per liter) were detected in more samples of water from wells completed in bedrock (25 percent of all samples) than in water from wells completed in stratified drift (7.5 percent of all samples). Iron and manganese were detected (at...
