Federal investigators with the Consumer Product Safety Commission and the Environmental Protection Agency have released preliminary findings regarding complaints by close to 2,000 U.S. homeowners about Chinese drywall, blamed for corrosion of electrical wiring and copper plumbing, foul odor and health problems.
The investigators reported on October 30 that the imported Chinese drywall has higher levels of sulfur and strontium than domestically-manufactured drywall. However, further testing is underway to determine whether the chemicals are responsible for health problems and the odor in affected homes.
The CPSC estimates that more that 60,000 U.S. homes could be affected by the tainted drywall, of which an estimated 7 million sheets were imported into the U.S. due to a shortage of domestic drywall. The product safety commission also reported that hundreds of thousands of sheets of Chinese drywall are still being stored in warehouses. The commission has identified, but not released the locales of, those warehouses.
In November, the commission will release the results of a study of 50 homes containing the drywall. Recommendations for how to remedy Chinese drywall problems are also expected in November. The $3.5 million cost of the federally-funded investigation is the largest in the history of the public safety commission.
