Background

The Nease Chemical Superfund site consists of 44 acres along state Route 14 two and a half miles northwest of Salem on the Columbiana-Mahoning county line.

Between 1961 and 1973, Nease Chemical produced various household cleaning compounds, fire retardants and pesticides—some of which included an uncommon chemical called mirex. The company used unlined ponds to treat waste from its manufacturing process. Hazardous substances seeped into the soil and ground water from these ponds as well as from buried drums that eventually leaked. (more...)

Site Updates

Latest Update - July 2008

EPA signed a document in 2005 called a record of decision which details the cleanup for soil, ground water and source areas on the Nease property. Plans to build the cleanup began in 2006 after a legal agreement called a "consent order" was signed between current site owner Rutgers Organics Corp. and EPA. Rutgers has agreed to conduct and pay for the cleanup at the site and to investigate contamination in the Middle Fork of Little Beaver Creek. EPA and Ohio EPA are overseeing all of this work.

Middle Fork of Little Beaver Creek

EPA is proposing a cleanup plan (EPA Proposes Plan to Clean Up Two Creeks (PDF) (8pp, 244K) July 2008) for the Middle Fork of Little Beaver Creek.

New samples of fish, sediment (mud) and water were taken from the creek in late 2005. Floodplains were sampled in 2006. This information was used to develop the recommended cleanup plan.

Nease Property

Rutgers started a $19 million cleanup on the Nease property in 2006. Treatment with "nanoscale zero-valent iron," or NZVI, began in one of the most contaminated spots in the ground water. NZVI is an innovative technology that injects microscopic particles of specially treated iron into the ground water. These tiny particles will chemically clean deep ground water.This innovative technology will allow the particles to flow with the ground water while cleaning the underground aquifer as they reach into the smallest cracks in the bedrock under the site. In 2007, Rutgers removed heavy contaminated liquids from the ground water that had sunk to the bottom of the aquifer. The company also provided treatment systems to some nearby homes to prevent potentially harmful vapors from entering the basements.

The rest of the site will be cleaned up using a combination of methods. Areas know as Ponds 1 and 2 will be cleaned up with a device that has rotating metal blades that will be sunk beneath the surface of the ponds to churn up chemicals and bring them to the surface to be captured, treated and disposed of before they can evaporate into the air. When most of the contamination is removed, the device will be used to mix a cement-like substance into the ground to prevent any remaining contamination from spreading.

Other ponds, as well as soil, will be covered with thick plastic sheets and a layer of clean soil.The cover will prevent rain from soaking through and further spreading contamination. Other areas will be covered with only clean soil.

A trench will be installed on the eastern and southern sides of the site to collect shallow ground water, pump it above ground and treat it to remove contamination.
