But not knowing the long term consequences of mixing and then burning those chemicals? It seemed like that was the quickest option just to get the trains moving again. There are reports of EPA officials still not going in to test things because they don’t want to risk exposure to the EPA employees, but they tell the East Palestine residents to shelter at home?! No remediation recommendations for PPE or their air filters? It just doesn’t make any logical sense.

I found the laboratory analytical results for the surface water samples at the site, apparently one of the bottles broke in transit from the site to the lab, so I think you are right about not having enough sample for the analysis.

What do you expect for climate havens or climate refugees in the coming 50 years?

All in your head. Sperm makes up around 10% of your total ejaculate volume and 70% seminal vesicles, 20% prostate. Average volume is around 5cc (tsp) but varies on person and length of time between ejaculating.

Doubt they don’t see it and it wouldn’t take much to reply with a response. Hopefully they do I would like to see either an agreement or fair criticism of Hancock.

How f#cked is the situation and can it be unf#cked in time? If so, by what means?

What do you think of Randall Carlsons take on anthropogenic climate change ?

We always hear about automation taking away supposedly menial jobs, such as frontward facing service industry jobs, industrial manufacturing, etc. With the advent of AI, do you see any possibility of management and corporate ownership being automated? Like, to me it seems like if I am supposed to imagine my doctor being a robot I can way more easily see any old business owner or CEO being one

Ohio EPA has released preliminary results for surface water samples collected throughout the Ohio River Basin. It appears that butyl acrylate was detected in surface water samples along this basin in several places. The detections are in the parts per billion (PPB) range which is quite low, however, there are no current drinking water or exposure standards for surface water for butyl acrylate. Without those risk standards, it is impossible to ascertain what current risks these results may pose to anyone fishing, swimming, or inadvertently drinking the water. Drinking water intakes from the river basin should remain OK as the water is treated before it is pumped into homes anyway. Anyone who lives near the areas listed in the following link should exercise caution and avoid direct contact with the river basin water and sediments.

Disclaimer: I do not work for any government agency. I do not represent Norfolk Southern or any of their contractors. I am an outside observer providing my knowledge to the public. My recommendations are based on an abundance of caution and coming in contact with the surface water may or may not pose an actual risk. But without concrete risk numbers to compare to from a toxicological report, it is impossible for anyone to say if the levels are safe or not for sure.

How false is the assertion that this climate change is not man-made (or at least not man-catalyzed), e.g. when some say that it's a cyclical change that would have happened anyway?

Is there any way a vasectomay could lead to development of a spermatocoele?
Happened to me, and I don't know if they are related.

Thank you for the AMA!
You said 3/4 species went extinct in the past events, does that mean there were so many species that we didn't even see? Any estimate on the number?
If a mass extinction happens in 2100, which species are in the line for extinction?
Thanks!

why argue for the lowering of CO2 when that is part of the plants food source? why do you want to starve plants and eventually starve people and animals?

See any superfund site or military base. They are riddled with problems that industry left behind when they went bankrupt or were just totally ignored due to "national defense priority" arguments, like burn pits in Iraq.

I wanted to thank everyone for there questions. This is my first AMA but I will certainly do more in the future if I see a need or if their is interest. I will still monitor this post, however, given my work schedule I can't dedicate a lot of time to online questions when my clients also have questions.

I highly doubt they are concerned with a matter of convenience in this scenario and I also doubt they are shipping these samples rather than direct transport for faster results.

Absorption of chemicals into plant material or uptake generally is more of a concern with heavy metals contamination. VC and other VOCs do not readily absorb into plant matter, either through respiration or through the root structure. In fact, the use of phytoremediation is quite useful for shallow soil metal contamination as certain trees will clean the soil quite effectively. In those cases, the plant material itself is treated as potentially hazardous and is tested as such. Depending on the concentration in the plant material it may be deposited into a hazardous waste landfill or normal landfill but in most cases it is never burned.

It sounded like it was there last option, but we wont know until a full report comes out. Burning chemicals is allowed under certain circumstances to prevent a much worse outcome (e.g. an uncontrolled explosion or chain reaction of the chemical).

To be fair, this was posted 9 hours after the AMA went live. They may just not have seen it.

They are performing real time and continuous air monitoring in the nearby area, which is standard protocol and should alert them to any potential VOCs in the air. If VOCs were at a level where PPE would be recommended I would urge my client (if they were my client) to evacuate the area instead, because PPE isn't a shield, its a band-aid which can prevent short term exposure but not a good long term solution. Air concentrations dissipate quickly radiating outwards, but may be concentrated in a particular wind direction. As long as they maintain this procedure, the town shouldn't need to worry about air exposure, unless wind conditions change. My understanding of the EPA's hesitation was the evaluation of the immediate area of the spill site, which is understandable but the workplan that the Norfolk consultants proposed included the removal of source material in the area. This requires specialized HAZMAT teams if the air in the immediate area of the site still poses an inhalation risk.
