The coronavirus pandemic caused schedule delays, human health impacts, and limited oversight at superfund National Priorities List sites

U.S. Environmental Protection Agency (EPA)

• Publication Date: 2022
• Quoted excerpt: "The coronavirus pandemic caused schedule delays and changed or extended exposures of human health and ecological receptors to hazardous substances, pollutants, or contaminants at 31 Superfund NPL sites."

Evaluation and application of the purge analyzer tool (PAT) to determine in-well flow and purge criteria for sampling monitoring wells at the Stringfellow Superfund Site in Jurupa Valley, California, in 2017

U.S. Geological Survey (USGS)

• Publication Date: 2021
• Quoted excerpt: "Perchlorate concentrations in samples collected for this study appear to be much higher than previously collected, unfiltered concentrations... A systematic study of quantifying perchlorate concentrations from unfiltered and filtered groundwater samples collected from the same wells would potentially allow for a more definitive conclusion."

Hydrogeologic framework, water levels, and selected contaminant concentrations at Valmont TCE Superfund Site, Luzerne County, Pennsylvania, 2020

USGS

• Publication Date: 2021
• Quoted excerpt: "In response to a request from the EPA in 2019... USGS prepared cross sections and maps to provide more information about the hydrogeologic framework at and near the site and assist in improving the conceptual site model using water level and contaminant data collected by the EPA in 2020."

Numerical modeling of groundwater flow in the crystalline-rock aquifer in the vicinity of the Savage Municipal Water-Supply Well Superfund site, Milford, New Hampshire

USGS

• Publication Date: 2021
• Quoted excerpt: "In 2010, tetrachloroethylene (PCE), a chlorinated volatile organic compound, was detected in groundwater from deep (more than 300 feet below land surface) fractures in monitoring wells tapping a crystalline-rock aquifer... A numerical groundwater flow model was developed by the U.S. Geological Survey to assess groundwater flow and advective transport of PCE-contaminated groundwater in the crystalline-rock aquifer of the Milford area."

Review of peer-reviewed documents on treatment technologies used at mining waste sites

EPA

• Publication Date: 2021
• Quoted excerpt: "Case studies examining treatment technologies used for remediating mining-influenced water (MIW) and mining wastes have been conducted at many hard rock mining sites and range in type from bench studies to full-scale field studies. The research in this report was conducted to capture the capabilities, efficiencies, technological and site-specific requirements, and lessons learned for technologies and methods used."

Remarks in Kearny, New Jersey

Compilation of Presidential Documents

• Date: October 25, 2021
• Quoted excerpt: "My infrastructure bill will also put Americans to work for long-overdue national environmental cleanups, like cleaning up the Passaic River, the Nation's most expensive superfund site."

Remarks on the Environment

Compilation of Presidential Documents

• Date: July 8, 2019
• Quoted except: "We've refocused the EPA back on its core mission, and last year, the agency completed more Superfund hazardous waste cleanups than any year of the previous administrations and set records in almost every year. We have done tremendous work on Superfunds."

Remarks on the National Economy

Compilation of Presidential Documents

• Date: December 8, 2009
• Quoted excerpt: "Already, more than 10,000 of these projects have been funded through the Recovery Act. And by design, Recovery Act work on roads, bridges, water systems, Superfund sites, broadband networks, and clean energy projects will all be ramping up in the months ahead."

Remarks at Sequoia National Park, California

Compilation of Presidential Documents

• Date: June 4, 2001
• Quoted excerpt: "Over the last three decades, nearly 3,000 hazardous waste facilities have been closed. We’ve made much progress in ridding our towns and cities of brownfields, and even more progress will be made over the next several years. And the Environmental Protection Agency has begun or completed cleanups in more than 90 percent of the sites targeted under Superfund."

Remarks to the Community in Hackensack, New Jersey

Compilation of Presidential Documents

• Date: March 18, 1996
• Quoted excerpt: "Now this brownfields effort is only part of the larger picture of environmental efforts we are making. Look what I saw today in Wallington. We have to repair the Superfund toxic waste cleanup program. Superfund has been an important tool in helping us to protect the environment."
