  • Climate change could affect groundwater recharge, scientists say

    (AXcess News) Washington - Elevated levels of carbon dioxide (CO2) in the Earth's atmosphere could seriously impact air, weather and vegetation. Now a scientist with the Agricultural Research Service (ARS) is taking a closer look at what could happen underground. If atmospheric CO2 levels double within this century, as many climate models predict, some areas could experience large increases in ...

  • How vulnerable is our groundwater?

    When water travels through soil and bedrock to the water table, it carries minerals, nutrients or chemicals from the surface with it. Environmental research is increasingly concerned with preferential flow, or the movement of water through pores and cracks at a faster rate and bypassing most of the surrounding material, either soil or fractured rock. A special section on preferential flow ...

  • Dr. Daniel B. Stephens recognized for contributions to NGWA

    Daniel B. Stephens, Ph.D., PG, PHg, founder and principal hydrologist, Daniel B. Stephens & Associates Inc., has received the 2016 Keith E. Anderson Award for outstanding contributions to the National Ground Water Association. “Throughout the last 42 years, Dan has served with energy and dedication, bringing forth his extensive hydrologic and geological experience, as well as ...

  • Oxidation of sulfides in waste rock piles

    Oxidation of sulfides in mining wastes produces high concentrations of sulfate, iron, and other metals and frequently also very low pH values. Compared with fine-grain mine tailings produced in ore treatment by flotation and other techniques, waste rock is just displaced material comprising large particles deposited into piles. In waste rock piles with high permeability and sulfide content, the ...

  • Measuring global soil changes

    Global change is increasingly affecting important terrestrial ecosystem functions such as the filtering and buffering capacity of soils, the supply of clean water, soil fertility, and consequently, the production of food, feed, and fiber. Recent studies and reports from the United Nations indicate that water and soil resources are both heavily under pressure. Worldwide about 2 billion ha of land ...

  • Restoring coastal wetlands? check the soil

    Rising sea levels and coastal development are threatening coastal freshwater wetlands with saltwater intrusion. While most ecosystem restoration projects have focused on surface water and groundwater, new research finds that conditions in the vadose zone, the unsaturated soil below the surface but above the water table, are of particular importance to seedling survival in coastal floodplain ...

  • NGWA offers short course, `Artificial Recharge of Ground Water`

    The short course, “Artificial Recharge of Ground Water,” is being offered September 22-23 in Baltimore, Maryland, by the National Ground Water Association (NGWA). The course will cover well recharge types, objectives, sources of water, and wellhead and wellfield designs. It also will examine aquifer storage recovery (ASR) systems in aquifers with either freshwater or impaired groundwater. ...

  • ASTM D6009 - 12 Standard Guide for Sampling Waste Piles

    This guide is intended to provide guidance for sampling waste piles. It can be used to obtain samples for waste characterization related to use, treatment, or disposal; to monitor an active pile; to prepare for closure of the waste pile; or to investigate the contents of an abandoned pile. Techniques used to sample include both in-place evaluations of the ...
