Status

Remediated

Work to make the East Tip safe was partly completed by the end of 2018 and the area opened as a public park in January 2021. The cost, estimated at 40 million euros in 2014, had risen to at least 61 million by 2016 (Wikipedia).

Story

The Irish Steel works, later Ispat, occupied the eastern side of the island, on the site of the 1869 naval dockyard. Slag and other production waste was dumped or stored on the spot: the East Tip took the island from about 60 to over 80 acres.

After closure, radioactive contamination and hexavalent chromium remained in the soil, with concern about the health risks of the residual contaminants.
