Ang's Journal

My self-image is that I am a rational person. I consider myself intelligent, well-educated, & curious. When I need to make a decision, I gather information (considering the source's expertise & bias & trying to find as many opinions & lines of evidence as possible), I look to history for information on previous, similar situations, & I try to identify my blind spots (cultural cluelessness, my own biases, areas of knowledge where I have zero experience or understanding). I draw a conclusion, but then I try to remain open to changing my mind, if I am presented with more input. BY NO MEANS do I consider myself a perfectly rational decision-maker, no one is. But I think my methods have given me a fairly decent algorithm by which to discern fact from fiction, to predict effects from causes, & to navigate the world.

But now, I am living in a world where facts are... whatever someone chooses to believe, I guess. Or rather, facts are whatever are being promoted as facts in a person's particular social niche, media bubble, or information silo. If you are a progressive, blue, Democratic-leaning voter in the USA, then facts include:

• The election system in the US is not perfect, but it is generally secure & correctly reporting the will of the voters.
  
• Sexual orientation & gender identity are complicated processes, & cannot be simplified to "conform to the norms of the majority or be considered evil".
  
• Human activity is contributing to global climate change, primarily via the release of carbon dioxide & methane to the atmosphere.
  
• Etc. etc. etc. It's boring to list them all. They even made signs to put in your yard that displayed an abbreviated list of "progressive facts".

But my point is that I believe these statements to be true because I have reviewed evidence that I find credible supporting these assertions, & I have not encountered much evidence that disproves them.

But if my method is solid, & I'm actually following it, then why did I have a conversation last week with A* that went like this?

Me: Can you give me one thing to look forward to from the next Trump Administration?
A*: Improved economic conditions.
Me: How will that be achieved? Through tariffs?
A*: No, I don't really understand how the tariffs are supposed to work.
Me: How then?
A*: Through energy independence.
Me: Even though the US is already the world's top producer of oil & natural gas...?

But instead of trying to argue, I sat quietly for a few minutes, thinking through my response to this reasoning. (Side note: it took an immense amount of effort to NOT argue based on what I consider facts.) I realized that I would never support the Trump Administration's approach to "energy independence", which (without a doubt) will be to promote increased extraction of & reliance on fossil fuels. So then I asked:

Me: Do you believe that human industrial activities contribute to global climate change?
A*: I don't know.

And there you have it. A* is an intelligent person. He worked in journalism for more than three decades. He's certainly seen the arguments regarding human impacts on the atmosphere & the consequences, but he doesn't believe the data that seems so irrefutable to me. But because he doesn't believe in the connection between releasing carbon dioxide & methane & dangerous changes to the global climate, he isn't going to worry about supporting an "energy independence" policy that will increase the burning of fossil fuels.

This realization has sent me spiraling. We had a near-fight earlier this year when I asked A* if he thought Haitian immigrants were eating dogs & cats in Springfield, Ohio & he also said he didn't know. How can he not know? How does he determine what is true & what is false?

But on climate change, it hurts more. I am literally a professional environmental scientist. While the global climate is not my specific area of expertise, I am knowledgable enough to have a pretty good grasp on the data & the arguments. But apparently, my husband doesn't believe me when I say that data models have predicted for DECADES that continued release of carbon dioxide & methane into the atmosphere is going to have horrible consequences for humanity (well, for the entire planet), & that so far, real-world observations either confirm the predictions made by modeling or suggest that they were too conservative & things are actually getting worse more quickly than predicted.

So, does A* believe anything I say? Does he think my career is just some big joke? What is he thinking when I prattle away about my models of natural attenuation of dissolved-phase contaminants in groundwater? Does he want to pat me on my head & tell me to just go back to the kitchen & stop worrying my pretty head? Poor deluded little girl, thinks she knows something about how the world works! It's cute!

I don't know how to live in a world where - it's not even a world where we don't agree on facts, but a world where we don't even agree on how to determine whether something is true or false. I don't know how to talk to people. I don't know how to process any incoming information or answer any questions. There's doesn't seem to be a point to doing those things anyway, because how are you supposed to decide what you should be doing, if you don't know what's true?

In this mindset, the mental obliteration promised by a long, hard drinking session sounds really good. So do other forms of annihilation. I'm not there, but it's been a long time since those things seemed so tempting.

This weekend was spent doing gardening tasks. I have been slowly beating back a bramble patch that is inconveniently located at the end of our driveway. I'm digging out the brambles & replacing them with flowers & shrubs. There is bedrock about six inches below ground surface here, so planting each plant feels like a sentence of hard labor. My hands are cramped today after hours swinging a pickaxe on Saturday & Sunday. But the new bed looks really pretty.



I planted Leadplant (Amorpha canescens), Coronado Hyssop (Agastache aurantiaca), 'Electric Blue' Foothills Beardtongue (Penstemon heterophyllus), Bee-Mine Red Bee Balm Monarda (Monarda didyma), Sonoran Sunset Hyssop (Agastache cana), Vermilion Bluffs Mexican Sage (Salvia darcyi), & Red Birds in a Tree (Scrophularia macrantha). There's also a Meadow Sage (possibly Salvia nemorosa, I'm not entirely sure) that was here when I moved in.

I thought all the species I chose were native to my area, but I reallllly didn't do my research! Leadplant & Meadow Sage are native to parts of Colorado, but not my specific region. Agastache cana is native to New Mexico & Texas, so at least I was close, while Agastache aurantiaca is from Durango... Mexico. Mexican Sage, surprisingly, is also native to Mexico; specifically, to the Sierra Madre Oriental. Red Birds in a Tree is native to southern New Mexico. The Foothills Beardtongue is a southern Californian. And my "native" from furthest afield is the Bee Balm Monarda, which originated in wide swaths of the Eastern U.S., but not anywhere in the Rocky Moutains or Four Corners regions.

Despite their foreign-ness, the new plants are getting good reviews from the (actual) locals!

As long as these plants can thrive in my high-altitude yard with little care from me, & provide beauty, nectar, & oxygen, they are welcome to become naturalized citizens of Loghill Mesa.

I've now been in Leadville for just over a month, working on this project. So... what is it that we're doing here?

In short, we are working to prevent the formation of acid rock drainage (ARD) on one portion of the California Gulch Superfund Site. There are four parts to this project - three little ones & one big one. First, the little parts:

• We are running a generator-powered pump in a groundwater well containing uncontaminated water (the GAW well) 24 hours a day, pumping approximately one million gallons per day into California Gulch (a small creek). We are doing this to keep the clean water from mixing with a plume of contaminated water, which would force a water treatment plant owned by the US Bureau of Reclamation (USBOR) to treat an increased volume of water.
  
• We were trying to rehabilitate an injection well (the Marian well) that pours ARD about 200 feet down a 14-inch-diameter PVC pipe into an old mine lateral, where it flowed into the Leadville Deep Mine Tunnel (LDMT), & then to the USBOR water treatment plant. This well, unfortunately, has completely collapsed at about 135 feet below ground surface (bgs) & probably can't be repaired. There is some evidence that the lateral has also collapsed. Next year, we may attempt to replace this well with a directionally-drilled well going straight to the LDMT. This will be a tricky bit of drilling, as the LDMT is about 500 feet away, about 200 feet bgs, & only about five feet wide. Also, we don't have any maps or other information about its specific location (it was built in the 1940s). Hitting it with a directional drill rig will be like shooting a bullseye on a buried target while wearing a blindfold.
  
• We are placing limestone gravel into several ARD ponds to see if the limestone can neutralize the ARD & the pond sediments. The ARD at the California Gulch site is intensely acidic, with a pH that is usually less than 2 & often less than 1 (for comparison, stomach acid is usually between pH 1.5 to 3.5). It is our hope that if we can raise the pH, the ARD will pick up fewer heavy metals & therefore will be easier to treat when it reaches the USBOR plant.

Then there's the big part of the project - the clean water diversion channel. Background: the area around Leadville was intensively mined for over 100 years, producing gold, silver, lead, & variety of other metals. Part of the legacy of this activity are large piles of mine tailings. This is rock that was removed while accessing the veins of metal ore. It contains a lot of pyritic minerals, which contain sulfur, which can create sulfuric acid when in contact with water. Once the water becomes acidified, it starts leaching heavy metals from the mine tailings - arsenic, zinc, manganese, cadmium, lead, chromium, etc. The resulting effluent is ARD. Treating ARD is expensive, so our approach right now is to reduce the amount of water that comes into contact with the mine tailings so less ARD has to be treated.



To this end, we are digging a channel that will intercept all the surface runoff & snowmelt from the mountainside above one particular set of mine tailings piles located in Stray Horse Gulch. The channel is lined with a plastic membrane to prevent any water from seeping through it. On top of the plastic membrane is a honeycombed web of plastic, which is filled with gravel.



This channel will divert the water around the piles & down another watershed (No-Name Gulch). The channel is about 2,400 feet long & ten feet wide. In order to give it enough slope to make sure the water flows across the hillside, we had to dig it pretty deep in some places - as much as 10 feet below the existing grade. The design requires us to make the side slopes no steeper than 3:1, so in places, the channel is 70 feet wide (30 feet on one side slope, 10-foot wide channel, 30 feet on the other side slope). We are moving about 8,000 cubic yards of soil, all told. It will look pretty nice once we get the side slopes revegetated.



One of the trickier parts of this project is that this channel runs smack dab through the middle of an eligible historic site, the Pyrenees headframe. It is a towering timber structure built over a mine shaft that extended 1,257 feet underground. Our channel runs right past its foundations, in part following the grade from a rail spur that used to haul off the bonanza of ore coming up from the Pyrenees mine. While excavating this section of the channel, we had an archaeologist on site to document anything we found. We have also had to excavate around some large concrete foundations, which probably used to house the giant hoist wheels that lifted men & materials out of the heart of the mountain. My nightmare is that one of the 50,000-lb. pieces of equipment I've got operating on this site will find a near-surface lateral by caving it in.



I think the project is going pretty well. We've been incredibly lucky with weather & I hope our luck last for just a couple more weeks. We've got to finish putting the layers in the channel, the gravel in the layers, then finish re-grading all the side slopes, covering all the slopes with erosion control blankets & seeding them with a blend of native grasses. We have one more culvert to install (in a berm at the outlet of the channel, which will control any floods that come down the channel, releasing them slowly through the culvert). We're building a small pond in an area where we dug out some topsoil. Then we will remove all of our construction roads, demobilize the office trailer, get all the equipment sent off, & go HOME.
