The Ostrava Lagoons
(Wikipedia)
Summary: The Ostrava lagoons are referred to as the area of three large lagoons near the Fifejdy housing estate in Ostrava, where waste from refinery production and later also from the regeneration of used lubricating oils was deposited, beginning at the end of the 19th century. This practice ended with the closure of the Ostramo chemical plant in 1996, to which the site belonged. During that time, the site developed into a huge ecological burden and was one of the most polluted in the country. Oil sludge regularly bothered the surrounding area with its smell. Since 2003, the site has been undergoing remediation. The main stage of the remediation, sludge removal, ended on 19 December 2020. Clean-up of contaminated soil, subsoil and groundwater will follow in the next few years.
