Geraghty & Miller subsidiary completes soil washing at brownfields site.Tampa, Fla.--(BUSINESS WIRE)--Dec. 19, 1996--Over 10,000 tons of soil contaminated contaminated, v 1. made radioactive by the addition of small quantities of radioactive material. 2. made contaminated by adding infective or radiographic materials. 3. an infective surface or object. with heavy organics have been treated successfully in a soil washing operation at a Massachusetts brownfields site. The operation was performed by Alternative Remedial Technologies, Inc. (ART), a subsidiary of Geraghty & Miller, Inc. and the companies' Dutch parent firm, Heidemij NV. The Monsanto Company operated a chemical plant at the Everett, Massachusetts Everett is a city in Middlesex County, Massachusetts near Boston. The population was 38,037 at the 2000 census. Everett is the only city in the United States with a bicameral legislature, which is composed of a seven-member Board of Aldermen and an 18-member Common Council. location from the mid-1800s to 1992. The 84 acres are now being remediated for construction of a 600,000-square-foot shopping mall. Monsanto is performing site cleanup under the Massachusetts Contingency Plan A plan involving suitable backups, immediate actions and longer term measures for responding to computer emergencies such as attacks or accidental disasters. Contingency plans are part of business resumption planning. . Brownfields are potentially contaminated industrial or commercial urban properties that have been abandoned or underutilized, but are suitable for redevelopment to help restore economic vitality to a community. Soil washing is a physical process which separates soil into oversize o·ver·size n. 1. A size that is larger than usual. 2.

Adj. 1. , coarse and fine-grained fractions, and focuses treatment on the contaminated fractions. Clean soils are returned to the site as backfill back·fill n. Material used to refill an excavated area. tr.v. back·filled, back·fill·ing, back·fills To refill (an excavated area) with such material. . ART began preparations for soil treatment operations at the Everett site in May 1996 with a treatability study that identified contamination in the oversize and fines fractions. The treatment plant was designed accordingly, and included attritioning and secondary hydrocycloning, in addition to the standard units. Treatment of fines was achieved through bioremediation bi·o·re·me·di·a·tion n. The use of biological agents, such as bacteria or plants, to remove or neutralize contaminants, as in polluted soil or water. . The treatment plant operated on-site from summer until late fall 1996, and in combination with the bioslurry system, achieved a 95% volume reduction. Clean soils were returned to the site as backfill and residuals were shipped off-site. This project demonstrated the flexibility of the soil washing system, and how equipment modifications can be made to meet site-specific requirements. ART President, Michael J. Mann, P.E., said: "This project fulfilled Monsanto's requirement to use appropriate treatment at each discrete area of the site. We are happy that soil washing contributed to a successful remediation." ART owns and operates 15-tons-per-hour and 30-tons-per-hour mobile soil washing plants. ART was founded in 1992 as a joint venture of Heidemij and Geraghty & Miller to introduce the Heidemij soil washing system to North America. ART's premiere project was at the King of Prussia King of Prussia, industrialized suburban area (1990 pop. 18,406), Montgomery co., SE Pa. It has glass and steel fabricating, food processing, printing and publishing, and varied manufacturing (textiles, liquified petroleum gas, water-treatment and electrical (KOP n. 1. Hill; mountain. ), New Jersey Superfund site in 1993, the first time this technology was used to remediate a Superfund site. In addition, KOP was the first full-scale soil washing project in the US. ART received three environmental engineering awards for this project. Geraghty & Miller and its subsidiaries provide a full spectrum of consulting, engineering, and contracting services in the environmental, transportation, civil, and industrial markets. It maintains a staff of more than 1000 in 27 offices in the US and UK. The parent firm, Heidemij NV, is a global environmental and infrastructure firm based in Arnhem, the Netherlands.
