  • First of all: Where in your system was the sample taken? At the well? At a tank? At a faucet?

    The answer to this question is important for the next steps.

    Be aware that high lead content can also be an issue for plant watering and even showering.

    If the sample has been taken at a endpoint (faucet) I would try to get another sample at the well directly. If you are “lucky” the acidity of the water is the reason lead is brought into your system from a section of your transport system. In that case replacing the transport layer (basically: Get new pipes) is the best approach - while it’s not cheap it is also not as expensive as filtering (or dealing with the health issues from lead, especially in the US).

    If the well shows the same values you are screwed. There are basically two scenarios then: Your well installation itself is the problem - this is in theory “fixable” but expensive, but you might accidentally even poisoning your neighbours then. (The way to find out if it’s your installation is either with specialised equipment or, for some confirmation, get a sample from a neighbour who ideally life upstream from you)

    If it’s not your well installation then it’s the well itself…and then you really really need a more extensive analysis: Lead in a ground water deposit is somewhat rare and often a indication something else is problematic - both because geologically lead is often next to other nasties, but also because human caused pollution with lead often goes with the real nasty stuff like arsenic,etc. And you really would want to find these. Then shit sadly becomes really expensive.


  • Nope,it hasn’t. If your glasses are fogging up in sync with your respiration rate or within a very short timeframe your mask is not sealing. Period. The only difference is when you have either have a valve mask, work with a face shield or similar things or in confined spaces - it’s basically impossible to fog up your glasses with a correctly positioned mask as the filter medium does work as a diffuser. If your mask does fog up suddenly despite a confirmed fit it usually is a warning sign for a breakdown of the filter medium.

    (And believe me, we tried really hard - as part of a customer contract we tested all major mask manufacturers available in the EU, with a sample size in the 4 digit range, including UV fluid and thermal imaging tests)

    I am fully aware that the equivalent of N95 is often seen as comparable to FFP2, but this is not actually quite correct. The FFP2 has a slightly worse filtration rate and a slightly higher resistance both for inspiration and expiration. Anyway, I intentionally wrote FFP3 as this is the recommended FFP class for Measles while within the NIOSH legislation only a N95 is recommended.



  • Healthcare professional here - but not your HPC and you cannot confirm that I am who I am so double check what I write:

    • Get your titers checked and get revaccinationes asap. If you are not vaccinated or are a non-responder talk to your healthcare provider. Isolate until then.

    • Mask up and keep your hands away from mouth, eyes and nose. You will need a properly fitting FFP3/NP95 mask here - measles are far meaner in terms of infectiousness than COVID. Tight fitting means: You have no leaks at the side - if your glasses fog up, if you can feel air going in or out next to your face,etc. it is not working. The usual “duckbill” masks with straps around the ears very very rarely fit properly.

    • Wash your hands and desinfect them properly.

    • Stay the fuck away from babies. Really. Please.

    • Proton is not an Email app but mainly an email provider that locks you into its own app.

    • Proton does not provide e2e encrypted email outside its own environment (so any mail within proton will be encrypted but not outside - and it’s far harder to do the later due to point one)

    • Proton is heavily run by US citizens living in the US - and therefore to some extend fall under the homeland security act and similar laws, including pressure by the current administration.

    • Proton claims to be based on Swiss privacy laws. One should be aware that Swiss data protection laws are amongst the weakest in Europe, that service providers can (and mostly are) forced to monitor cross border traffic and that Swiss intelligence services have a long history of unlawful overreach and extremely close cooperation with US services. To what extend Proton is affected by this is unclear, unlike other Swiss based service providers they refuse to comment on this(and they would be allowed to comment, don’t get me wrong)

    Just to be aware. I know there are a lot of fans of proton on Lemmy,but there are far better services available nowadays. If the Swiss privacy law does not bother you Infomaniak is an option, alternativly mailbox.org is an option within the GDPR sphere. (Can be bad or good depending on your own situation)

    Neither of them is an app, nevertheless,but they work with any major app,e.g. thunderbird.
