The Jordan Aquifer is the largest source of groundwater, extending from northeast Iowa to south central Iowa, and is the source of much of Iowa's agricultural and industrial water. Besides pollution, the aquifer is threatened by overuse in well-source irrigation, ethanol production, and decreased replenishment caused by extensive field tilling.
The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...
These are lists of invasive species by country or region. A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location ...

The number of impaired water body segments — which can be lakes, wetlands and parts of streams — declined about 4% from the last report in 2022. But just 24% of stream segments and 30% of ...
The four dominant fish species known in the United States as Asian carp are introduced invasive species.They all cause harm within their new environments. Specifically, the four most well-known species of invasive Asian carp are black carp (Mylopharyngodon piceus), grass carp (Ctenopharyngodon idella), silver carp (Hypophthalmichthys molitrix), and bighead carp (Hypophthalmichthys nobilis).
