  • I can’t support this comment enough. My last job was chemical and biological safety oversight but had a lot of overlap with regular safety people. It takes no extra time to ensure a circuit is properly locked and tagged out because anyone working on that circuit should already have their own lock on it, using a gang lock if there are multiple people.

    Then you still prove test prove. For those not in the biz, this means to test your sensing equipment on a known live circuit, test the circuit being worked on, then retest the tester as before because breakers get mislabeled and meters break all the time.

    On that note, there’s the time an energized circuit almost killed my sister-in-law. She said she understood 120v wiring, so was changing out a light fixture. She asked me for some help with getting it mounted, so I asked her if the breaker was off, and she assured me it was. As I was working on it, it let out a loud pop, slightly zapped me, and blew the breaker.

    I’m normally a very nice, chill person, but I was fucking livid. I asked her to show me the breaker she turned off and she pointed to the fucking wall switch. Someone had switched it on, likely out of habit. I inspected the wiring and found she used a cracked wire nut and overtightened it until the hot wire protruded well past the end. I wasn’t grounded but I was holding the fixture… with my left hand. I could have had a heart attack if I had been grounded

    It’s a boomer joke, but I was what almost killed her. I had never been so angry with someone before. We still love her, but we don’t let her work on anything with stored energy anymore.







  • It really depends on a lot of factors, including water quality, substrate composition, and the extent of the digging. The majority of microbial activity in most waterways isn’t in the water, but instead in a region called the hyporheic zone, a surprisingly thin layer of sediment at the interface between surface and ground water.

    Digging and dredging both are fantastic ways to disrupt this layer. Microbial communities will redevelop rapidly, but their composition will be different. The makeup of the stream/riverbed will have significantly changed; different types of microbes reproduce at different rates, with fast reproducers initially crowding out slower growers; and the products of the activity of some microbes provide the conditions under which other types of microbes can flourish. The composition will change over time and may take months or even years to return to a steady state, and even then that state may be quite different than before digging or dredging.


  • Tl;dr: It seems the group was well intentioned but this actually could have been pretty environmentally detrimental.

    According to this article, it appears the issue is the team used a digger in some capacity. Details on how are sparse.

    I’m a microbiologist (environmental micro), but I studied a few things in grad school. A big chunk was hydrology and riverine engineering, more specifically erosion control and environmental remediation. I promptly went on to work in a different field, because who does what they actually study in university?

    I’ll spare you the details (unless you want them, I will go HAM on erosion control autistic data dumping because I rarely get to talk about this) but it’s pretty easy to fuck up a river if you start digging it up. Given they mentioned flooding concerns, I checked to see if the area is in a flood plain and confirmed it is.

    Humans engineer rivers in floodplains to prevent the previously cyclical flooding as well as reduce erosion. If those controls are damaged, the flooding and erosion can resume, and downstream effects (…pun?) can be pretty serious for humans and the environment.

    I’d need more information to confirm exactly what happened, but there may be some merit to the complaints about their project. If they didn’t have even a cursory environmental impact assessment, they could have done a lot of damage while trying to do something good.
