Equus Beds Groundwater Management District No. 2 Sustainability Assessment

The objective of this study was to assess the prospects for sustainability of the portions of the High Plains aquifer (HPA) in the Equus Beds Groundwater Management District No. 2 (GMD2) in south-central Kansas. For the purposes of this report, sustainability is defined as being achieved when spatially averaged water levels are stable with time, i.e. the average annual water-level change over an area is zero for a period of several years. Given the temporal variability in annual precipitation and groundwater use, there will be year-to-year rises and falls in spatially averaged water levels across GMD2. However, those changes will average out to zero over a period of several years if the aquifer is being pumped at a sustainable level. The specific purpose of this study was to determine the average annual water use that would produce stable areally averaged water levels over a given area.

High Plains Aquifer Index Well Program: 2016 Annual Report

This report provides a description of conditions as of late winter 2017. The report consists of (a) an update of the hydrographs for all of the index wells and for the expansion wells in the vicinity of the Scott and Thomas index wells (one well near the Scott index well and three wells in the vicinity of the Thomas index well); (b) an interpretation of the hydrographs from all of the index wells; (c) a discussion of the installation of the new index well in GMD4; (d) an update and interpretation of the hydrographs of the expansion wells in the vicinity of the Haskell index well; and (e) a discussion of climatic indices and radar precipitation data and their relationship to annual water-level changes at six of the wells and to water use in the vicinity of those wells.

Tracking the Global Supply of Critical Materials

Friday, January 26, 2018

No country in the world produces all of the mineral resources necessary for modern society. International trade plays a critical role in providing these raw materials, forming a global network of production, export, import, and use. This network must continuously adapt to national and international developments in science, technology, politics, and economics. As a result, information on the global flow of raw materials plays a fundamental role in improving national and international resilience to potential supply disruptions and market changes.

New Report Examines Groundwater Management on the High Plains

Cover for 2016 AGI Critical Issues Forum Report

The High Plains/Ogallala Aquifer (HPA), which offers a compelling yet complex illustration of how geoscience vitally intersects society, is the subject of a new report from the American Geosciences Institute. This report outlines the findings of the 2016 Critical Issues Forum, which examined state approaches to the HPA's regional groundwater challenges.

Interactive atlas of coal mine maps in Kentucky

The Kentucky Mine Mapping Information System is produced by the Kentucky Energy and Environment Cabinet to allow users to access maps of coal mines and mined out areas in Kentucky. Users can search by company name, seam name, or state file number (SFN). For each map, overview information is provided where available (map year, mine status, mine owner, mine type, seam thickness, etc.), and users are directed to the map. Users can also overlay information on oil and gas activity on the map.

Interactive map of hazardous waste cleanups in the United States

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.
