Bhopal's Solar Evaporation Ponds Await Scientific Remediation
In Bhopal, India, there are three big ponds near an old factory that were supposed to clean up the factory's waste.
But these ponds have leaks, and the bad chemicals from the factory are getting into the ground and water.
This has been happening for a long time, even before a big accident in 1984.
Experts say these ponds need to be cleaned up properly to stop the pollution.
They also say the area should be turned into a park so people can't build houses there, which would be dangerous.
The government hasn't done much to fix the problem yet.
Three Solar Evaporation Ponds (SEPs) near the defunct Union Carbide plant in Bhopal require scientific remediation.
The ponds, built in the 1970s, have leaked toxic chemicals into the soil and groundwater due to inadequate lining.
350 metric tons of chemical waste from the plant have been incinerated, but the SEPs remain untouched.
Experts recommend proper remediation, scientific disposal of sludge, and declaring the sites as city forests to prevent residential development.
Contamination from the SEPs has been an ongoing issue since the 1980s, affecting the surrounding areas.
