Biofilm and Slime Cleaning The Jefferson Memorial


So there is a Black Slime Biofilm taking over the Jefferson Memorial, Lincoln Memorial, Washington Memorial and The Arlington National Cemetery as CBS This Morning highlighted. The US  National Parks Services is at it’s wits end on this “invasion” and do not know how to mitigate it.  This is not a small thing to take lightly, BUT there IS an answer and a solution to this problem.


What is this stuff?

Is it dirt, mold, good, bad? Temporary or Permanent? Where did it come from?

Kinda reminds me of the 80’s movie Invasion of the Body Snatchers.

Is it just native to Washington, DC or is it a common black bacteria that COVERS the WORLD? We know it is unsightly and is it causing damage, and HOW do we eradicate this stuff?

I was recently in Israel and seen there, I’ve been to DC, Louisiana, Texas, Florida, North and South Carolina, Seattle,WA, and live  right here in Northern California.

Although, I have not personally inspected the DC Memorials myself, I have a feeling I know what this strange SLIME and Biofilm is. In my opinion, it more than likely is a cyanobacteria called Gloeocapsa Magma, a black bacteria that is anywhere and everywhere we live.  We know that this bacteria, when not dried out, will facilitate MOSS and Algae build up.  Once this bacteria spawns and continues to multiply, it starts to “RUN” and “Streak down” the building, causing the BLACK MARKS on the sides of the building, YOUR HOUSE and Gutters… called TIGER Stripes.

This bacteria settles on your roof, sidewalks, park benches, playground equipment, lawn furniture, driveway… basically, again, everywhere… and YES, IT DOES CAUSE DAMAGE to the surface of the stone, tile, concrete finish. It literally is EATING the STONE ALIVE.

Powerwashing IS NOT the ANSWER will only cause MORE DAMAGE and FEED the BIOFILM the WATER it lives in… DUH!
