but every thimble helps
legacy issues are perhaps as important as what has been done and is ongoing if we transfer from fossil carbon to other energy supplies
methane to atmosphere or "fatter" stuff into aquifers or surface hydrogeology or even just making a flaming tar pit after a while might be reduced by effective decommissioning
well failure while in use is quite low, under 0.1%(well done)
historic well failure is averaged between 1% and 2%, some are messier than others(most are fairly minor, but some are awesome)
some fields have a far higher legacy failure rate due to geology and or the way the field was exploited and abandoned
ps i am not picking on oil, minerals and coal etc have similar issues, nuke legacy is off the scale
the folk capping legacy wells as properly as they know how to is rather nice
do it without conflict is wise and hopefully good diplomacy for obtaining means to make it normal practice
a small aside re nuke, afaik sellafield is now an entirely decommissioning operation with a 100yr plan
after the final leak in the THORP unit it was too hot to mend which put a stop to the reprocessing stuff
they have stored stuff, lots of stored stuff, last official Pu number was 350 tons, the high and medium stuff with a box and paperwork is extensive, the tube alloys onwards legacy stuff is a bit random and has planet changing potential(not in a bangy way perhaps but a popped "pond" or a "fire" might challenge most ecosystems short and long term)
other nuke facilities are available and have a variety of protocols in place, that ranges from trying to be safe to "call it a nature reserve" |

a personal knowledge example of "chemical" legacy is a 30000 lt reaction pan and agitator full of gone wrong sulphonation batch
the batch set, it started as mostly naphaline and oleum, it was over 115% acidic and fuming nicely when it was buried in river flood plain clay
not exceptional as an item, the barrels and buried heaps etc are probably more worrying, that on site dump has 150 yr worth of waste chems and kit in about 20 acres, 2 world wars and a lot of brass n muck making assorted industrial things has created a cocktail cabinet that i do not want to consider too much
there might be a few tons of mustard gas gone wrong in the mix, but nobody has wanted to look for it too hard as it is rumour with no paperwork
the organic stuff is very varied
afaik in that one any radionuclides are incidental from kit etc rather than "process", the chemical stuff covers inorganic and an organic cocktail of mostly unknown nature, what we do know about it is all very bad
that is perhaps the best monitored/maintained site in that area, some are legacy without responsibility, some are lost and some, old and newer, are "hidden" |
