FEARS are mounting that toxic contaminants may have leached from the polluted Ravenscraig social housing building site after dirty floodwater spewed out onto a busy Greenock road. The escape from the sprawling 83-acre estate — which has confirmed 'multiple exceedances' of potentially harmful chemicals — lasted for more than nine hours, according to eyewitnesses. Developers of the poisoned land insist that the health and safety position on contamination 'has not changed' as a result — but did not explain how they had arrived at this conclusion. Meanwhile, Inverclyde Council — despite setting a planning condition that 'all surface water originating within the site shall be intercepted within the site' — says it has no remit to act.
