Welcome to the homepage for the Portsmouth Environmental Monitoring program.
This Department of Energy provides ongoing communication to the public regarding its Environmental Management programs to detect and eliminate hazards at or near the Portsmouth Gaseous Diffusion Plant site.
Information provided covers such topics as sampling methodology, key terminology, radiation sources and protective measures. DOE is committed to working with the community and the state to ensure the safety and health of our workforce, our neighboring communities and the environment.

Monitoring and Reporting
DOE works hard to ensure communities near our facilities maintain safe and healthy environments. To do this, the Department has implemented a robust monitoring program that meets or exceeds state and national regulatory standards. At the Portsmouth Site, DOE has installed and maintains an extensive monitoring program that samples for radiological and chemical contaminants in air, water, soil, sediment, and biota (animals, vegetation, crops) on and near the plant site. Each year, more than 10,000 environmental monitoring data are collected, reviewed, and reported. The results of these monitoring efforts are reported in the Annual Site Environmental Report (ASER). The ASER is prepared each year for the public.
The ASER is a comprehensive summary of environmental activities and monitoring data from DOE’s Portsmouth Site. Current and past copies of the ASER are available to the public at:

Zahn's Corner Middle School
Located approximately 2.5 miles northeast of the Portsmouth Site, air monitors located adjacent to Zahn’s Corner Middle School detected very low levels of airborne neptunium in 2017 and americium nearby in 2018.
A separate report by Dr. Michael Ketterer of Northern Arizona University claimed the presence of enriched uranium within the school. The Scioto Valley Local School District Board elected to close the school on May 13, 2019.
In response to community concerns, DOE deployed an elite team of certified health physicists from DOE’s National Laboratories and the National Nuclear Security Administration to conduct the investigation at Zahn’s Corner Middle School, accompanied by representatives of the Ohio Department of Health and interested members of the Piketon community. The team of radiation safety experts collected 44 surface samples over the Memorial Day weekend, including specific areas requested by the community to be tested. Air samples also were collected from both inside and outside the school.
Results from sample analyses conducted by experts at Savannah River National Laboratory show no radioactivity detected above naturally occurring levels, and no cause for public health concern. There is no public health or safety risk from radioactive material preventing Zahn’s Corner Middle School from re-opening. The Department at each step conducted its investigation in a thorough and transparent process. Its experts, who conduct radiological investigations around the world, employed proven industry standards in gathering and analyzing the samples. DOE is committed to the safety, health and protection of its workforce, the general public and the environment at all of its sites.
Additionally, the Department has committed to fund an independent third-party assessment for the Pike County community to include additional sampling and analysis in a scientifically sound and disciplined manner to address community concerns.

Community Information Sessions
The Department of Energy hosted two community meetings in August 2019 to present details on the sampling and analysis methods and results and answer questions regarding the Zahn's Corner Middle School sampling event.
