The National Ground-Water Monitoring Network compiles information from over 7,000 groundwater monitoring wells across the country, including Federal, State, and local groundwater monitoring networks. Although the image above only shows the contiguous United States, the interactive map also includes wells from Alaska, Hawaii, Puerto Rico, Guam, and the U.S. Virgin Islands.
As the amount of atmospheric carbon dioxide has increased over recent history, so has the acidity of oceans worldwide. The changing acidity of the ocean has many ecological and economic impacts, one of the most serious being its effects on marine life and fisheries. The impact of ocean acidification is intensified in colder bodies of water such as those off the coast of New England, a region with a large fisheries sector.
The U.S. Environmental Protection Agency (EPA) provides an interactive map of hazardous waste cleanups across the United States. The "Cleanups in My Community" map provides a huge amount of information on thousands of cleanups of many kinds. For every cleanup, users can access and download reports, assessments, compliance actions, and the EPA's assessment of the potential for any contaminated land to be used for renewable energy development.
Less than one-third of the U.S. is mapped at the level of detail necessary to make informed planning decisions on a local scale concerning natural resources, natural hazards, infrastructure planning, and environmental stewardship. In the Great Lakes region, the Great Lakes Geologic Mapping Coalition (GLGMC), a group including U.S. and Canadian state and provincial geological surveys, is producing detailed 3D geologic maps that are helping to provide decision-relevant information to Great Lakes state communities. Due to similar regional geology, these state surveys can work together, sharing their expertise and resources so that each can better address geologic issues in their area. Working with the communities, the GLGMC provides and makes maps that solve problems such as groundwater contamination and resource development.
The U.S. Department of Energy's Bioenergy Knowledge Discovery Framework provides an interactive map of biomass production potential across the United States (at the time of writing, maps do not cover Alaska and Hawaii). The aim is to show how much biomass may be available for bioenergy production from the present day through to the year 2040.
