Alison and Andy, whose son Fraser, nine, was diagnosed with cancer aged 17 months, have been asking the council to look into the cancer rates.
The couple described the council’s investigation as a “small-scale look around Deene Quarry”.
“[This] is not going to identify widespread problems, that we know exist,” said the parents, in a statement.
“Our own efforts have uncovered several other at risk areas which have not been examined by the council, according to this report.
“Have the children and people of Corby not suffered enough? We’ve been patient and given the local authority plenty of time to come clean – but they have chosen not to do so. It is so disrespectful.
“Without seeing the full data sets, that the council has point blankly refused to share, this summary report is not worth the paper it is written on.”
The council said while it was publishing the full reports, raw data could not legally be published because of “strict and important data protection rules”.
