Imported Drywall Information

The Louisiana Department of Health (LDH) has been working with federal partners since 2009 to provide support to Louisiana residents impacted by human health hazards related to the corrosion of copper and other metals inside homes due to the presence of drywall made in China. 

Historical information is available on this page, however, for the latest updates about problem drywall, please visit the CPSC Drywall Information Center

Assessment of Health Hazards Related to Indoor Copper Corrosion Possibly Associated with Imported Drywall

  • The Louisiana Department of Health (LDH) is currently working with federal partners and other states to evaluate the potential for human health hazards related to the corrosion of copper and other metals inside homes, and the presence of drywall made in China. The U.S. Consumer Product Safety Commission (CPSC) is the lead federal agency in the Chinese drywall investigation, which also includes the U.S. Environmental Protection Agency (EPA), the U.S. Centers for Disease Control and Prevention (CDC) and its subsidiary the U.S. Agency for Toxic Substances and Disease Registry (ATSDR), as well as other states' health agencies.
  • Our Section on Environmental Epidemiology and Toxicology has been taking drywall-related health calls through our Indoor Air Quality hotline since February 20. The hotline number, which has been publicized through the print and broadcast news media in the greater New Orleans area, has received calls from more than 675 residents, more than half of whom have agreed to participate in an informal health survey.
  • In late April and early May, we compiled response data from our health survey into a report that shows the spread (geographic) and scope (symptomatic) of the drywall problem as it relates to the health and indoor environment of residents who have called the hotline and reported effects. The report, entitled "Foreign Drywall Complainant Surveys," offers a snapshot of physical characteristics of the homes where health effects have been reported, health effects experienced by members of the households, and some demographic information. It also features a map with completed surveys by parish (county), and identifies the level at which reporting homes in these parishes meet a "case definition" for the presence of Chinese drywall, originally established by the Florida Department of Health.

  • In May, we conducted almost a dozen on-site, visual inspections of homes in the Greater New Orleans area and the Northshore of Lake Pontchartrain to confirm self-reported effects of the identified cases.
  • In May, we also escorted scientists from the U.S. Environmental Protection Agency and U.S. Centers for Disease Control and Prevention (CDC) on additional visits to five of the case homes. The EPA conducted real-time air sampling, trying to identify "contaminants of concern," and will return to conduct in-depth testing.
  • We have been communicating with the Governor's office and the Louisiana Congressional delegation, which has resulted in swift action from the federal government on the ground in Louisiana. Governor Jindal and Senator Landrieu have been strong advocates for federal help on this issue.
