Groundwater is a critically important source of water in the U.S., supplying fresh water for drinking supplies, agricultural irrigation, and streams, rivers, and ecosystems. However, groundwater is becoming increasingly depleted in most aquifers around the country, with impacts including shrinking aquifer storage capacities, land subsidence (and associated impacts like higher flood risk), and declining freshwater resources for communities and ecosystems. To mitigate and reverse the depletion of groundwater storage in local aquifers, many communities are turning to managed aquifer recharge (MAR) and aquifer storage and recovery (ASR). MAR and ASR practices vary depending on local geology, groundwater and recharge water composition, local land use practices, and water use requirements. Implementing MAR and ASR requires careful planning to both maximize groundwater replenishment and protect groundwater supplies from contamination.
The U.S. Geological Survey's New England Water Science Center hosts an interactive map that displays current water conditions for each state in New England. The map has real-time, geolocated water data for New England, including:
The U.S. Geological Survey’s National Water Information System (NWIS) created an interactive tool that maps water resources data at over 1.5 million sites across the country. The search tool allows the user to find sites by street address, location name, site number, state/territory, and watershed region. The sites are sorted into five main categories:
The combination of frequent droughts, changing climate conditions, and longer fire seasons along with urban development expansion into wildland areas has resulted in more difficult conditions for managing wildfires. Over the last several decades, the size of wildfire burn areas has increased substantially and nine of the 10 years with the largest wildfire burn areas have occurred since 2000. Wildfires are causing more frequent and wider-ranging societal impacts, especially as residential communities continue to expand into wildland areas. Since 2000, there have been twelve wildfires in the United States that have each caused damages exceeding a billion dollars; cumulatively these twelve wildfires have caused a total of $44 billion dollars in damages. As of 2010, 44 million homes in the conterminous United States were located within the wildland-urban-interface, an area where urban development either intermingles with or is in the vicinity of large areas of dense wildland vegetation. These challenging conditions present a unique opportunity to adapt existing wildfire policy and management strategies to present and future wildfire scenarios.
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.
