Why We Could Smell Anuvia Plant Nutrients' Fumes Despite Production Being Shutdown

Anuvia Plant Nutrients shut down production yesterday due to complaints of fumes from their process. Apparently they had a malfunction of some sort. There were still fumes in the air this morning causing people to think that the odor had to be Shelley's Septic Tanks. Even if some of the odors were from Shelley's, some were from Anuvia due to a temperature inversion last night. Temperature inversions can affect us by holding smoke, pesticides, and particulate matter close to the ground instead of naturally dissipating into the atmosphere.

We need to be careful when we identify odor sources to avoid placing blame in the wrong place.

How to Identify if an Inversion Exists:



  • Measure air temperature at 6–12 inches above the soil and at 8–10 feet above the soil. An inversion exists if measured air temperature at 8–10 feet above the soil is higher than the measured air temperature at 6–12 inches above the soil. Be sure the instrument is shaded and not influenced by solar heating.
  • Morning dew
  • Morning fog (indicates that an inversion existed prior to fog formation)
  • Smoke or dust hanging in the air or moving laterally
  • Overnight cloud cover is 25% or less
  • Inversions can begin forming three to four hours before sunset and can persist until one to two hours after sunrise

Recording Odors and More: Advice for Sullivan Ranch and Stoneybrook Hills Residents

I haven't written about the Mount Dora City Council meeting on December 15th yet for several reasons. You can listen to a recording of the meeting here.  Although I was there, I spent all of the meeting in the hallway as the room was too crowded during a pandemic, so I didn't hear much of what was going on.  Although fixing the smell is important to me, my health and my significant other's health is more important.  It was clear to me that there was no regard for Covid-19 when the decision was made to hold the meeting in the City Council Meeting Room instead of the much larger Community Room. I don't know the room measurements but I believe that it was unsafe to be in. (I have a contract tracing certificate from Johns Hopkins.) You can calculate the number of safe minutes using the square footage, ceiling height, and the number of people present here.   I don't know how big the room is but I assumed it was 1,000 square feet with 12-foot ceilings. I don't know ho

The Daily Sludge Report Zero Days Without A Smell Report Check back for updates as reports come in It's 2:07 am on a clear and beautiful night . I took the dog out for a late walk, and there it was, waiting for me like a cat stalks a lizard... The stink. This morning was another day of stink . My phone was blowing up and I hadn't even opened my laptop. There'll be a lot to unpack today so hold on.  This was sent to Anuvia FB. "Hello. I live in Tangerine. March 2, 2020, and many other days in the last two years, I have taken my dogs out for a walk. As soon as we go out the door, we are hit by the strong smell of fertilizer and human waste smell. We often have to go back inside and wait until the smell goes away. Most of the time it just sits there like a heavy cloud. I am a captive in my own home, and my dogs have to suffer. This smell makes my throat burn and I start coughing. With the threat of coronavirus COVID-19 that specifically attacks the lungs, an

Mount Dora's Wastewater Treatment Plant Smells.

To: grusauskasj@cityofmountdora.com Letter 1 Dear Mr. Grusaukas,   I had to go to CVS in Mount Dora last night at 10:00 p.m.  I was traveling north on 441 and when I got to Stoneybrook Parkway there was a horrible sewage smell, even with the car windows up.  When I got to the top of the hill to the water plant the smell was enough to make you gag!  I continued to smell it all the way to Renningers.   45 minutes later when I was returning home and traveling south on 441 the stench was still there.  I cannot believe the poor residents of Stoneybrook are subjected to this.  What is wrong with the water plant?  I travel to Leesburg all the time and go right past their water plant and it never smells.  Mount Dora’s water plant is also an eyesore!  It is covered in black mold and looks disgusting!  Other towns have their water plants painted and they look neat and clean.   Mount Dora painted the stalls around the dumpsters in town to look nice, why are they allowing the water plant to be suc
