EPA Research Updates

Can spending time in natural environments lead to better health? An EPA study found a correlation between the amount of green space near homes and chronic stress reduction.

Lake Champlain has a phosphorus problem. EPA researchers are working with small dairy farmers in the state of Vermont to explore whether pasture-based rotational grazing can be a viable, cost-effective, option to help to reduce phosphorus loading to the lake. The goal is to find an equitable, socially acceptable solution that supports farmers in the region.

The Yurok Tribe in Northern California depends on the health of the Klamath River for much of its food and water supplies. With support from EPA, the Yurok Tribe Environmental Program is currently conducting a study to identify areas of water resource vulnerability and resiliency, assess impacts on food security and tribal health, and increase the Tribe’s adaptive capacity to prepare and respond to changes in the environment.

EPA researchers are helping cities measure their resilience Researchers looked at vulnerabilities to environmental changes in Washington, DC, and Worcester, Massachusetts. Their report describes a comprehensive and flexible workbook that cities can use to become more resilient to these changes.

Webinar: Lead in Schools and Selecting Lead Free Plumbing Products


Tuesday, November 28, 2017 | 2pm ET 


This month’s small water systems webinar will include two presentations related to lead in drinking water. The first, Testing Drinking Water in Schools and Reducing Lead Levels, will be presented by Edward Viveiros from EPA’s Office of Water. This presentation will provide background on lead in drinking water and discuss recommended steps for ensuring effective school sampling, remediation and communication measures. The second, Identifying Plumbing Products that are Certified as Lead Free, will be presented by Michelle Latham from EPA’s Office of Research and Development. This presentation will highlight a tool designed to help consumers identify lead free plumbing and water system products that have undergone third-party certification testing.
