The cement industry, which is in a state of flux after years of decline, is taking some of the blame for the chemical stain that has been found in several sites around the world.
The companies have been accused of using a chemical called cement powder to remove the stains.
But in a joint statement, cement manufacturers and environmental groups said that it was too early to determine the impact of the chemical powder on the environment.
The chemical is called cement powders, and the chemical used is calcium carbonate.
It is used in cement construction to seal the concrete blocks.
It has been widely used in the industry since the 1980s.
But it is a toxic chemical, and it is not a good option for cleaning up the soil.
“The cement industry is the largest and most profitable industry in the world and the only one that relies on chemical waste for its supply of cement powder,” said Michael Wertheim, a spokesman for the environmental group Friends of the Earth.
“Cement powder is toxic, it’s corrosive and it can easily spread through soil.
If the industry’s chemicals weren’t used, we wouldn’t have found the problem in the first place.”
The US Geological Survey has identified two cement sites in South Africa that have been affected by the chemical.
The first, in the town of Glamorgan, was found in 2014.
According to the USGS, the site had a “highly corrosive” chemical that could easily penetrate the soil and cause erosion.
The second, in Mokamba, in South-East Cape Province, was also found to have a highly corrosive chemical.
In both cases, the cement companies have since been fined for their failure to provide the necessary tests to confirm the chemical was being used.
But there has been no confirmation from the companies about the chemicals used in their factories.
The USGS is still investigating whether the chemical could have caused the problem.
“If a company can identify the cause, it will be the first step in taking corrective action and removing the chemical.” “
The companies said they were also working with the US Environmental Protection Agency (EPA) to find a solution to the contamination. “

The EPA has also launched an investigation into the use of cement powder powder in cement production.
