Groundwater Quality: Decadal Change

Almost one-half of the U.S. population rely on groundwater for their water supply, and demand for groundwater for public supply, irrigation, and agriculture continues to increase. This mapper shows how concentrations of pesticides, nutrients, metals, and organic contaminants in groundwater are changing during decadal periods across the Nation.

Groundwater Levels at Selected Observation Wells in the South Coast of Puerto Rico

Depth-to-water is measured periodically to evaluate hydrologic conditions at important aquifers throughout Puerto Rico. The water-level measurements from observation wells can be computed to understand the hydrologic stresses acting on aquifers and how these stresses affect groundwater conditions.

Hydrologic Conditions of Selected Reservoirs in Puerto Rico

The following graphs show water surface elevations above NGVD 1929 in selected reservoirs for several years, including 2015. The purpose of these graphs is to compare water surface elevations during 2015 with water surface elevations observed during years when documented droughts have occurred.
