When she moved to the countryside two years ago, Natalie Dugdale thought it would be the spot to raise her family.
Close to a lagoon in north Wales, she thought she could walk her baby, toddler and dogs on public footpaths.
Now she is part of a group of people who are worried they may have been poisoned by years of exposure to waste, and are campaigning for voluntary blood testing across Wales.
Members of a newly formed campaign group for those living alongside some of the sites concerned have told BBC Wales they had been left "frightened and upset" and said testing would help provide "peace of mind".
Natalie could not believe her local lake in Llwyneinion, just outside Wrexham, had once been a dumping ground for chemicals and wants to see blood testing introduced.
Llwyneinion lagoon was recently branded "a shame on Britain", following the documentary into historical dumping of PCBs by US chemical giant Monsanto, which had factories in Wrexham and Newport.
Sheen's Buried programme team found elevated levels in soil samples taken in an area open to the public beyond the fenced-off lagoon, as well as at 13 other suspected dumpsites for the firm's waste across the country.
Michael Phillips was also found to have "very high" levels of PCBs in his blood, after private testing commissioned for the documentary.
The banned chemicals were once widely used and revered for being non-flammable and hard to break down – but are seen today as the first "forever chemicals" - which are building up in the environment, threatening wildlife and human health.
