The demand comes after the Pollution Control Department (PCD) was ordered by the Supreme Administrative Court last week to make a recovery plan for the waterway. It must also monitor the recovery implementation for a year until the lead drops to standard levels.
The contamination was blamed on the Lead Concentrate Co, which operated a lead mine nearby for 30 years. After winning a concession in 1967, the company was forced to shut down in 1998.
When the PCD found the creek was contaminated, it built a rock check-dam to screen out lead sediment. It said dredging the creek would have a negative impact and spread the lead-tainted sediment.
“PCD’s method has already been proved by the court to not have worked over the past 10 years,” Surapong Klongchantuek, a member of the Klity creek rehabilitation monitoring working group, said.
The group wants PCD to urgently draw up a recovery plan and allow locals to participate in the process.
PCD’s director-general Wichien Jungrungruang said his agency would follow the court’s order instructing the department to draw up a rehabilitation plan.
He added the department would organise a conference and invite environmental experts and local people to brainstorm and draw up a plan to revive the tainted creek. The conference is expected in the next two months.
