Site Background
The Anaconda Aluminum/Milgo Electronics (Anaconda/Milgo) site is located in Dade County on the 3600 block of N.W. 76th Street in Miami, Florida. The site comprises approximately three acres of land along the north and south sides of N.W. 76th Street. Areas to the north, south, and west of the site are in active industrial use. A large residential trailer park is located to the immediate east of the site. Several other Superfund sites are located within a few miles of the Anaconda/Milgo site.
The Anaconda portion of the site covers approximately one acre. Operations began in 1957 and ceased in 1983. Operations consisted of an electrochemical process using acids and an aluminum-laden caustic base to produce a film of protective coating on aluminum.
Companies on both portions of the site disposed of liquid wastes via on-site drainfields.
Both the Anaconda and Milgo portions of the site are currently being reused for industrial activities.
Threats and Contaminants
Sampling conducted in 1987 indicated heavy metal contamination in the ground water. The ground water contained cyanide and heavy metals such as cadmium, lead, zinc, iron, selenium, chromium, and copper from the former manufacturing and process waste disposal practices. Sediment, surface water, and soils contained heavy metals such as mercury, selenium, and arsenic. The contaminated ground water reached the Biscayne Aquifer, the sole source of drinking water for South Florida.
Site Cleanup Plan
In 1993, PRPs undertook a short-term cleanup action to remove contaminated soils. Follow-up investigation revealed that the site no longer posed a threat to public health or the environment. In 1994, EPA chose a "no further action" cleanup plan for site-related soil and ground water contamination.
Cleanup Progress
In 1993, the potentially responsible parties conducted a removal of source soils, pursuant to a removal order. This excavated area measured 50 feet by 7 feet, with a depth of 7 feet. All soils were removed and disposed of at an EPA-approved facility.
Following soil cleanup, ground water was monitored on a quarterly basis for one year; the final measurement occurred in 1995.Since a determination has been made by EPA that the site no longer presents a threat to human health or the environment, the site has been deleted from the National Priorities List (NPL) in 1998.
Site cleanup activities are being led primarily by potentially responsible parties (PRPs) with oversight by EPA.
Enforcement Activities
General and Special Notice Letters were sent out to potentially responsible parties (PRPs) beginning in August of 1991 and ending in April of 1992.
PRPs completed an investigation of the site as specified in an Administrative Order on Consent signed in July 1992 and revised in November 1992.
In 1993, the PRPs conducted a removal of source soils, pursuant to a removal order.Community Involvement
EPA has conducted a range of community involvement activities at the site to solicit community input and to ensure that the public remains informed about site activities throughout the site cleanup process. Outreach activities have included public notices and information meetings on cleanup progress and activities.

Future Work
Since a determination has been made by EPA that the site no longer presents a threat to human health or the environment, the site was deleted from the NPL in 1998.
