NEW ST

The one-acre Dover Gas Light Co. Site originally began as a coal gasification plant in the City of Dover. Approximately 10,000 people live within one mile of the site and an estimated 45,000 people are served by public and private wells within three miles of the site. From 1859 to 1948 the Dover Gas Light Co. produced gas from coal. This gas was used for street lamps and other purposes. Upon closing of the plant in 1948, all of the structures except a brick garage were demolished. Much of the plant was removed, but sections of the tanks and other process equipment were buried on site. These underground structures contained coal oil and/or coal tar. In 1984, remains of the coal gasification plant were found. For several years the site was used as an unpaved parking lot for a museum next door. That parking lot area is now paved. A cemetery and historic church are located on the same block. Seven of Dover's 14 municipal supply wells are located within one mile of the site; however, the Dover municipal system draws water from a lower, uncontaminated aquifer. The municipal wells were sampled in 1988 and 1991 and did not show signs of contamination. These wells were sampled again during the supplementary groundwater investigation currently underway. No site-related contamination was found.
