Index / Uranium (Nuclear Minerals) / Related Environmental Issues / Hydrogeology & Water Resources

Barabara Tasch reports that groundwater from two aquifers in the central U.S. contain uranium levels that are significantly higher than the U.S. Environmental Protection Agency (EPA) maximum contaminant level (MCL) and may have been so a long time.

What is more, these two aquifers provide drinking water to almost 6 million people, and almost 2 million of them live less than a mile from the contaminated groundwater, according to a study lead by two researchers from the University of Nebraska-Lincoln.

The High Plains aquifer is the largest in the US - It spans from Texas to... More →

David Sneed reports that with an average output of 675,000 gallons a day, the Diablo Canyon nuclear power plant will hold that distinction until at least November, 2015, when a 50-million-gallon-per-day commercial desalination plant in Carlsbad is scheduled to begin production.

The Diablo Canyon desalination plant consists of a system of powerful pumps, large tanks and a series of long, white reverse osmosis filtration tubes. The filters in those tubes are so fine they can remove even the microscopic salt particles that give ocean water the name saltwater.

Isolated along ... More →

Valerie Bragg reports that so-called environmental (aka adversarial) organizations want to join with the state in the Virginia Uranium, Incorporated lawsuit. Earlier, Virginia Uranium filed a suit against the Commonwealth last month to have the ban lifted. A representative of the adversarial group called the Roanoke River Basin Association tells ABC 13 that they and another adversarial group called the Dan River Basin Association have filed a motion to intervene in court, which means they want to join the state in the lawsuit and act as an ally. They also said they filed a motion to dismiss t... More →

California regulators approved a $3.2 million grant Tuesday to bring safe water to a California trailer park where three dozen households for years have been provided with tap water containing ?dangerous? levels of uranium that could be reduced by a centralized reverse osmosis systems located at the source for the 36 homes.

The grant from the California Water Resources Control Board will pay to install lines from a new well in a nearby town to the Double L Mobile Ranch Park outside Fresno, in the agriculturally rich Central Valley. One in 10 public water systems and up to one in fou... More →

Gross alpha-particle activities and beta-particle activities for all 47 samples were analyzed at 72 hours after sample collection and again at 30 days after sample collection, allowing for the measurement of the activity of short-lived isotopes. Gross alpha-particle activities reported in this report were not adjusted for activity contributions by radon or uranium and, therefore, are conservatively high estimates if compared to the U.S. Environmental Protection Agency National Primary Drinking Water Regulation for adjusted gross alpha-particle activity. The gross alpha-particle activities at 3... More →

Open-File Report 2009-1143
U.S. Geological Survey

This talk was presented by U.S. Geological Survey (USGS) geologist Susan Hall on May 11, 2009, at the Uranium 2009 conference in Keystone, Colorado, and on May 12, 2009, as part of an underground injection control track presentation at the Texas Commission on Environmental Quality (TCEQ) Environmental Trade Fair and Conference in Austin, Texas.

Texas has been the location of the greatest number of uranium in-situ recovery (ISR) mines in in the United States and was the incubator for the development of alkaline leach t... More →

It is actually a frozen soil wall around the four crippled reactor units, intended to block the flow of groundwater and prevent its mixing with contaminated water. The principal benefit of the frozen barrier compared with a physical barrier is that it avoids the challenges of building a wall around such underground obstacles as pipes, and creates a seamless barrier. Its effectiveness was demonstrated in tests held in March through April of 2014, when it maintained the ground temperature below 0 degrees Celsius.

The barrier is being funded by the government, with construction being u... More →

The U.S. Geological Survey has reported that naturally occurring radionuclides in the groundwater of southeastern Pennsylvania may pose a health hazard to some residents, especially those drinking water from wells drilled in the Chickies Quartzite. Water from 46% of wells sampled in the Chickies Quartzite and 7% of wells sampled in other geologic formations exceeded the USEPA maximum contaminant level (MCL) for total radium.

Radon-222 may pose a health problem for homeowners by contributing to indoor air radon-222 levels. The radon-222 activity of water from 89% of sampled wells ex... More →

The Gunnar Legacy Uranium Mine has been vacated in northern Saskatchewan for more than 50 years. And Saskatchewan Research Council Vice President of Environment Joe Muldoon says the company abandoning the site near Uranium City, Gunnar Mining Limited, left the site in 1964 with little to no cleanup or decommissioning.

However, the SRC has recently gained approval to start cleanup of the largest portion of the site, the three mine tailings deposits. The SRC was appointed to oversee the cleanup of the site by the Saskatchewan government when they took over responsibility. They needed... More →

Alyssa Goar reports that a recent report out of the University of Nebraska-Lincoln found high concentrations of uranium in different areas around the Ogallala aquifer (also known as the High Plains aquifer). This aquifer brings water to many regions, including West Texas.

We have some pretty stringent protocol for testing our water and there are certain chemicals that are known to be a problem and the EPA and also the state agency - the Texas Commission on Environmental Quality - have limits set that we adhere to, explained Aubrey Spear, Director of Water Utilities for the City of L...
