Radon, a colorless and odorless gas, is commonly found in groundwater in Pennsylvania. This web tool allows interactive display of Pennsylvania Water Science Center measurements of radon in groundwater samples from wells. All data presented here is publicly available and a data download tool is provided that will output all currently-displayed data. 

Landsat 4 was launched on July 16, 1982, with joint control of the program by NOAA, NASA, and the U.S. Geological Survey. Each federal agency took on a different role.

Although only two Landsats were originally anticipated, the program’s principal scientists sought to launch a third satellite for continued coverage because they found a wide variety of applications for the data. There was also interest in advancing the sensors and improving the data.

A long string of Earth-observing orbiters began with NASA's Earth Resources Technology Satellite (ERTS). Launched in July 1972, it was the first satellite explicitly designed to study our planet. Three years later, the satellite was renamed Landsat 1. Outlasting its one-year design, Landsat 1 retired in January 1978.

In response to recent harmful algal blooms (HABs) that have occurred in many of the large water storage reservoirs in the Willamette River Basin the USGS is measuring related water-quality parameters in Detroit Lake, Blue River Lake, and Cougar Lake. The USGS has also developed profiler tools that allow users to see how the water quality parameters vary with depth in those reservoirs.

The USGS provides information and tools needed to help solve problems posed by invasive species across the country. Key components of USGS invasive species science include developing novel prevention, forecasting, early detection, decision support, and control tools.

USGS Scientists published a StoryMap showing projected changes in land use, flooded area, and wildlife habitat in California’s Central Valley for five scenarios of future climate and water management.
