 Measuring Groundwater Contaminants
Through Image Analysis Tools - Groundwater that has become contaminated by chemicals that are sparingly soluble in water, such as chlorinated solvents, presents a serious ecological and human health risk. Groundwater remediation scientists at EPA’s National Risk Management Research Laboratory are using absorption and light refraction analysis to determine the saturation distribution of common groundwater contaminants in order to facilitate research on the development of effective methods for remediating sites impacted by these chemicals.

 People-Power Research: Ideas for Earth Day - The National Risk Management Research Laboratory presents many innovative research projects that directly involve homeowners and other stakeholders in real-world applications. In connection with Earth Day 2009, we offer a sampling of these technologies to illustrate how individuals and communities can benefit from their application. Read more |
 Accessing Treatment Data for Drinking Water Quality - For more than 30 years, EPA has provided information to the U.S. drinking water systems—large and small—that serve millions of American consumers. In that time, EPA researchers have identified hundreds of potential contaminants to drinking water quality. To help stakeholders navigate this body of information, EPA recently commissioned a new online tool... Read more |
 Gauging the Effectiveness of Riparian Buffers - Heavy loads of nutrients, sediments, pesticides, and other materials can be harmful to delicate aquatic ecosystems. Riparian buffers – vegetated regions adjacent to streams and wetlands – are a common means of intercepting and controlling these pollutants as they enter water bodies. EPA considers nitrogen one of the top stressors to aquatic ecosystem health. To determine how to better protect these environments from excess nitrogen... Read more |
 Unlocking the Climate Archives - Within our continent’s aquifers lie archives of long-term climate changes describing precipitation recharge in watersheds. Aquifers act as filters that smooth out short-term climate fluctuations and record continental climate signals. Past temperature signals (paleotemperatures) are stored with dissolved noble (inert) gases in groundwater. Using noble gases as proxies, NRMRL hydrologists are sampling paleotemperatures in the Elwha watershed on the Olympic Peninsula in Washington State. Read more |

 Technology Assessment for Investigating Future Air Quality - NRMRL’s Energy and Climate Assessment Team (ECAT) assesses emerging energy and pollution mitigation technologies and their potential effect on harmful emissions. With a focus on the energy and transportation sectors, ECAT helps EPA to better understand how technological evolution can impact future air quality. Read more
