Marino and Hallett Cove residents remain unconvinced after a fiery public meeting at which Boral was supposed to clear the air over its Linwood Quarry.

The two-hour meeting held last week at Hallett Cove Baptist Church was attended by about 75 residents and representatives from Boral, Marion Council, Primary Industries and Resources SA (PIRSA) and the Environmental Protection Authority (EPA).

Residents told the meeting that loud blasts and clouds of grey dust from the Boral-operated quarry, on Clubhouse Rd, affected their lives and their homes.

Marino Residents Association president Fran Southern told the meeting the same questions remained unanswered from previous discussions with Boral. ``They still haven’t tested the dust and we have concerns about the carcinogens,’’ she said.

“We want independent testing done this summer.”
