Information board


HCH contamination constitutes a much smaller threat in Hajek than in Jaworzno. This is mainly because of the total sum of toxic HCH waste buried in both dumps. It is also obvious from the first impression one gets when visiting the sites – Jaworzno has more brownfield features than Hajek due to the proximity of original chemical plant. In case of Hajek, former chemical production unit is over 100 km distant and the waste is buried much deeper than in Jaworzno. Unpleasant phenolic odour is present at both sites. It is spreading on many places and with higher intensity in Jaworzno, where also other organochlorinated pesticides (DDT, dieldrin, methoxychlor, etc.) are dumped. Quite on the contrary, the remediation progresses are further at Hajek site than in Jaworzno.
