Bathymetry and Water-Quality of Surface Water Bodies in Cook County, Illinois
Surface water bodies in Cook County are used for stormwater detention, domestic and industrial uses, recreation, and commercial navigation. However, the bathymetry (elevation of the bottom surface) of most water bodies in Cook County has not been measured or mapped comprehensively. Similarly, water quality in most of these water bodies is unknown.

Statewide sampling to determine spatial distribution, prevalence, and occurrence of per- and polyfluoroalkyl substances (PFAS) in Illinois community water supplies, 2020–21
Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals that have been manufactured and used globally since the 1940s. PFAS are used for their oil- and water-repellent properties, ability to reduce friction, and their flame-retardant nature. PFAS are widely used in a variety of products, including clothing, carpet, food packaging, and firefighting foam. The...

Multiorder hydrologic position in the conterminous United States: A set of metrics in support of groundwater mapping at regional and national scales
The location of a point on the landscape within a stream network (hydrologic position) can be an important predictive measure in hydrology. Hydrologic position is defined here by two metrics: lateral position and distance from stream to divide, both measured horizontally. Lateral position (dimensionless) is the relative position of a point between the stream and its watershed divide...
