Contaminated American Drywall – The Silent Killer

Updated – August 18, 2014

I started this website Contaminated American Drywall at the end of January 2013. My main purpose was to inform, educate, and try to save lives of known victims, and those unsuspecting victims, who may have purchased one of the thousands of newly built or foreclosed homes. From the inception of the website, to the present day where I have some assistance from a few sources because of the volume of calls and emails, I have been able to help many individuals and families. Every family that I have helped and tests were sent to the labs, 100% have come back positive.

Contaminated American Drywall

Although I deal primarily in Toxic American Drywall, I will not turn away anyone that possibly might have Chinese Drywall. I consider myself an expert in both American and Chinese Toxic Drywall, after almost 7 years of study, being a “Victim”, and working as an advocate to those in need. I want to give you one of the latest updates that seems to escape the news media, as I consider this a major development in the recent months.

We have been waiting for over two years for a Health Consult from the Center Of Disease Control. They were to release this in May of 2012, but continued with a multitude of excuses. Everyone who was a Victim knew that they were holding out until most of the Chinese Drywall Settlements had been approved, before they would release these documents. The main reason also was that for the last few years they had been concealing the fact that there was also Toxic American Drywall. They were hiding this under the guise of Chinese Drywall.

So on May 2, 2014, the (CDC) Center for Disease Control published a Health Consult that FINALLY recognizes both Chinese and American Toxic Drywall. It also lists all the medical Symptoms that are associated with these Toxic Drywalls. All of the above symptoms are identical to what all the Victims have been saying across the entire United States. We have also made some additional discoveries and have also learned that each American brand drywall, even though the end results are the same, have some individual characteristics.

We are also finding that some new homes built in 2013, and even some built in 2014 have exhibited some of the same symptoms, as previously built homes during 2004 to 2009. Most of these homes have an ASTM number of C36. But in these new homes they have the new drywall with the latest edge tape, and the newest ASTM C1396. In my home I have United States Gypsum SHEETROCK Drywall. My lab testing registered CARBON DISULFIDE, ACETONE, and TH228 (RADIATION), and a few other chemicals that didn’t belong.

My builder is ADAMS HOMES OF NORTHWEST FLORIDA, INC., a large builder that builds in 7 states. They have built THOUSANDS of homes in North Port, Florida and the surrounding area. I have found additional homes just like mine, as well as other models that my builder built, that has the same characteristics as my TOXIC drywall home. I have found so many homes, businesses, and even Government buildings that have the same characteristics of other Contaminated buildings, I had to stop putting them on my website, and instead just file them in my folder.

My website CONTAMINATED AMERICAN DRYWALL is still and will always remain unsponsored, because it is a tell it like it is, no holds barred website. I will print any name if they are the guilty culprit, and in the last 16 months not one individual has attempted any kind of legal action against me, because I will only print the truth. Everything on my website, I can back up with data and in black and white. You can’t fight the truth and facts!

I am a 100% Disabled Vietnam Veteran, who was exposed to Agent Orange while serving in Vietnam. Many years later it is unfair that ADAMS HOMES OF NORTHWEST FLORIDA, INC. built a home that contained TOXIC AMERICAN DRYWALL. The facts are what they are – and that is this builder has had all this time to step up to the plate, and make things right. Yet they chose to deny and do nothing. I bought my home in July 2007, and since 2009 I have had 8 hospital stays, which resulted in major damage to my heart and other vital organs.

I do what I do because I am a man of Honor, and I don’t want to see other people purchase one of these Toxic homes and become as sick as I and other Victims have in the past number of years. In North Port alone there are presently 1300 homes that are vacant, as of this time, and our studies and random sampling indicates that many of these homes possibly have the same characteristics as our own Toxic homes have.

    Thank you for all this important information and bringing it out to the public. The company that manufactured this drywall must have known that this stuff was a health hazard and continued to make it and probably involved in a cover-up. It is terrible that our veterans having served our country and are dealing with disabilities already, are subject to the affects of this product. It is a real slap in the face to our veterans and all the people who built their dream homes. Adams Homes can’t just walk away and not do something about this.

    Thanks for the email about my blog. I was aware of limited problems with American and Chinese drywall and should have also included them in my blog. Love the website and video. Awareness is the answer to getting resolution to the drywall health problems effecting so many children and adults. To think you spend a fortune on a home and have to replace the appliances, plumbing, drywall, electrical and HVAC is ridiculous.

    There was a house in Clermont that was built with contaminated Canadian drywall. There is a CPSC report on it. The drywall was purchased at 84 lumber and determined to be very toxic.

    CPSC link to the report: http://www.cpsc.gov/PageFiles/80492/drywallidi1.pdf

    Hope this helps out a little and I will try to forward more information as I come across it.

    I hope that “someone” is listening and will set you free from this mess. You bought A home in good faith and cannot even live in it. There is no excuse for American made Drywall to be contaminated and those that are suffering should be compensated. Bless you for trying to help others in this mess and I pray that you will get some help!

    Charles your new youtube video Contaminated American Drywall is awesome! I hope this gets the attention from the right people so they can help you with your mess, by getting the spot light on the parties that harmed you.

    Someone sent me information that was posted online about an Elementary School here in North Port, who was having odor problems. In dealing with the drywall issues, I suspected that it may be related. So this early afternoon, January 25, 2013, I drove to Lamarque Elementary School, 3415 Lamarque Ave., North Port. As I entered between the double set of doors I could detect an odor. But as I passed through the second set of doors it hit me pretty good. This was a smell that I am all to familiar with, and it reminded me of my own home. It was a sweet, sickly, chemical-metallic smell. I asked to speak with the principal, but she was busy. So I spoke to the office staff, and one went back and advised the Prinicipal about what I said, and she was told to refer me to the County School Facilities Manager. I called him, but I have no doubt that I won’t hear that telephone ring. Before I left as I stood talking to the young lady, my voice started to get raspy, and I mentioned to her. Surprisingly they took some of my cards to my website, after a small discussion (education). I worry about all those children, so I researched and called the leader of the school’s (PTO) Parent Teacher Organization and left a message. Hopefully she will call me back.

    Spent the day today, Sunday – shooting the video, “From One War – Vietnam — To Another – USG. I sucked a lot of gas from the drywall today, and will pay dearly the next couple of days. Even though I am sick, I want to thank United States Gypsum Corporation, and one of their legal teams located in South Carolina. You inspire me and make me drag myself up and out of bed each morning! You might ask why? Because I am a crazy Disabled Vietnam Veteran, who will keep getting up when I am knocked down. You will never win this war, because I will fight you, and I will win because I have morals and Honor. These seem to be the qualities that are missing in your Corporation!

    BREAKING NEWS: Columbia Analytical Services Revised my Case Narrative because when my testing was done, that was correct, but they failed to show it met the Identification Guidance for Homes with Corrosion from Problem Drywall, by the CPSC, dated March 18, 2011. This testing used ASTM D5504-08, or similar chamber or headspace testing. Sample CAS Lab #1, resulted in a hit of Carbon Disulfide above the Limit of Quantitation. (Meaning – PROBLEMATIC DRYWALL). Keep following for more discoveries and Breaking News!!

  8. Charles A. Hummer says:

    The United States Senate should be ashamed of themselves, for not mentioning anything about the American “Victims”, who are sick from exposure to Contaminated American Drywall. They passed HR4212, and failed to mention any American Drywall Companies, just China. United States Gypsum has known at least since 2006, that there was defective drywall, and failed to inform the American people. It is a crime what they have done, and many of us “Victims” would not be sick now, had we known back in 2006. The United States Attorney General should investigate and prosecute USG, for their crimes against the American people

    A great site Charles, it elevates your story to a new level. I hope I can help you tell the world your story, and in turn get somebody to stand up and do the right thing and make the repairs you need.
