The United States Department of Energy currently owns 191 acres (77 ha) of the original LOOW property, on which the Niagara Falls Storage Site (NFSS) is located.
[2] The location was selected because of its proximity to chemical manufacturing plants, to Fort Niagara, to the New York Central Railroad, and to water and electrical power.
[10][11] A 166 ft (51 m) concrete silo was erected within the east boundary of the LOOW, immediately next to Porter Center Road, which was publicly accessible.
The 10-acre (4.0 ha) mound is used for the storage of radioactive waste and residues, and the grass-covered "interim cap" is designed to retard both rainwater infiltration and radon emission.
[2][4][15] A 98-acre (40 ha) parcel of land from the original LOOW property was given to the United States Air Force, on which they located an experimental rocket fuel plant called the Youngstown Test Annex Site.
A school, several small farms, a 13-acre (5.3 ha) campground, and the Basilica of the National Shrine of Our Lady of Fatima, which attracts thousands of visitors annually, are also located in the former LOOW site.
[7] Author Ginger Strand wrote about the LOOW in her 2008 book Inventing Niagara: "the Army Corps engineers, currently charged with the cleanup, readily admit they don't know everything that went on there".
[8]: 242 An extensive study conducted by the United States Army Corps of Engineers concluded in 2014 that there was "no evidence of potential source areas or releases of contamination to groundwater, surface water, or soil associated with any of the ground disturbances evaluated" at the former LOOW site.
[5] A 2005 article in the Niagara Gazette alleged that radiation at the site was causing an ongoing hazard for the nearby Lewiston-Porter Central School District.
