- Concentration and trend of 1,4-dioxane in wells sampled during 2002–2017 in the vicinity of the Tucson International Airport Area Superfund Site, Arizona
- Groundwater, surface-water, and water-chemistry data, Black Mesa area, northeastern Arizona—2013–2015
The USGS Arizona Water Science Center provides resource managers and the public with critical water resource information for Arizona and the Southwest. Two recent publications help explain the hydrology and water quality at sites located at both ends of the State. Scientific Investigations Map 3385 shows the concentration for VOCs monitored between 2002 and 2017 at the Tucson International Airport Area Superfund Site. This map provides both the current status as well as the trends for 1,4-dioxane groundwater contamination in the area. Open-File Report 2017-1127 describes the hydrology and provides groundwater, surface-water, and water-chemistry data for groundwater and springs associated with the Navajo aquifer located in northeastern Arizona. This aquifer is of concern because it is the primary source for groundwater in the 5,400-square-mile Black Mesa area.
