Microbes Deep Inside the Earth - The first hints that microorganisms lived in the deep subsurface hundreds to thousands of meters below ground emerged in the 1920s from the studies of Edson S. Bastin, a geologist at the University of Chicago.

Single-celled organismsbacteria, fungi and protozoathrive on all parts of the earth's surface. Their habitats range from the boiling hot waters of thermal springs to the pleasantly cool soils of backyard gardens. Microorganisms provide essential services to other creatures by decomposing waste products and forming nutrients. Some microbes also ... More →

Hugo A. Loaiciga and Stephen Renehan indicate that their paper synthesizes and interprets data pertaining to the evolution of average water revenue, water use, and the average cost of water supply in the City of Santa Barbara, California, from 1986 to 1996, a period which included one of the most devastating droughts in California in the 20th century.

The 1987-1992 drought hit the study area particularly hard. The City of Santa Barbara was dependent exclusively on local sources for its water supply. That made it vulnerable as the regional climate is prone to extreme variability and... More →

Joe Romm reports that an alarming satellite-based analysis from NASA finds that the world is depleting groundwater, the water stored underground in soil and aquifers, at an unprecedented rate. A new Nature Climate Change article, The global groundwater crisis, by James Famiglietti, a leading hydrologist at the NASA Jet Propulsion Laboratory, warns that most of the major aquifers in the world arid and semi-arid zones, that is, in the dry parts of the world that rely most heavily on groundwater, have been experiencing rapid rates of groundwater depletion for many years. The groundwater in some o... More →

According to the report, Alternatives for Managing the Nation's Complex Contaminated Groundwater Sites, at least 126,000 sites across the United States have contaminated groundwater that requires remediation, and about 10% of these sites are considered "complex," meaning restoration is unlikely to be achieved in the next 50 to 100 years. The report added that the estimated cost of complete cleanup at these sites ranges from $110 billion to $127 billion, but the figures for both the number of sites and costs are likely underestimates.

Several national and state groundwater ... More →

In the appropriations bill which funds the government though September 30, 2016, NGWA was pleased to see an increase in National Ground-Water Monitoring Network funding for FY2016. The Network will receive $3.6 million to continue implementation of the program, an increase of $1 million over FY2015 levels. The increase in funding will allow for additional implementation of the National Ground-Water Monitoring Network across the U.S. The program assembles water-level and eventually water-quality data from state agencies across the country onto a publicly accessible web portal, thus allowing for...

About 115 million people, more than one-third of the U.S. population, rely on groundwater for drinking water. As the U.S. population grows, the need for high-quality drinking-water supplies becomes even more urgent.

About 43 million people in the U.S. rely on groundwater from private wells. 1 of every 5 groundwater samples from parts of aquifers used for drinking water contained a contaminant from geologic or manmade sources at a level exceeding a potential human-health concern. 6,600 wells were sampled for this study. 1.3 million chemical analyses performed for this study.

"Natural attenuation" refers to the ability of a ground water system to rid itself of contamination resulting from a spill or improper disposal of wastes. It is emerging as a viable and in some cases, the preferred remedy for contaminated ground water.

The basic concept of natural attenuation is not new. We depend on it, for example, in municipal wastewater permits that allow treatment plants to discharge a certain amount of wastes without unduly depleting oxygen in surface water. Another example is the use of drainfields in septic systems.

President Obama Releases FY2017 Budget, Yields Mixed Bag for NGWA Priorities...

On February 9, President Barack Obama released what is described as an aspirational $4.1 trillion budget, pressing his case on environmental and energy initiatives. The White House championed a concerted cross-agency effort devoted to water innovation noting $260 million in the budget is devoted to activities that boost research and data surrounding water efficiency and water supply issues. Given persistent drought in the West, the Bureau of Reclamation WaterSMART program will receive a 12% boost. Also,... More →
