This is not meant to give you heartburn but meant more as a headsup on being aware of what may/may not happen to your tap water.
Many places are beginning to have problems with the zebra mussel reaching crisis levels in the local lakes which may be the source of their tap water. These are an invasive species and they tend to do all kinds of things like stop up intakes and create headaches for water suppliers, so there is an increasing amount of effort given to figure what to do. One of the major problems is how easy the mussel is moved from one lake to the next by careless boaters.
I live in a smaller suburb of Austin, Texas which draws water from a different source than Austin but I do watch what happens in the Austin news. One of the local news items has been a major problem with the odors in the tap water caused by the zebra mussel. Stinking water for a few weeks is not good!
But the more recent news is far more likely to change how we deal with our tap water if we keep things in our tank which are sensitive. Things like snails and shrimp, come to mind.
So just an early heads up on what may become a problem in your tanks. Not an immediate concern, perhaps, but something to be aware of, just in case.
The Austin water supplier has been catching lots of flak from people who could not cook, drink, or bath in their water for a few weeks. Easy to imagine that they will have to do something to avoid that happening again, right? So the news is that it will take about 18 months to install "copper generation" equipment but in the meantime, they will begin treatment using Sodium Permanganate to kill the mussels.
I do not find specific info on how this will change the tap water but I might guess that neither will be good for having a stable situation in our tap water as treatment may either be intermittent or potentially harmful to items sensitive to copper.
Far more study and experience will be needed to know how it actually works out but it may be something to be aware of as it is not likely to be a major news items in your area before it is added. It hit the news here only because of the stink over bad water and other places may be more proactive to avoid both the stink in the water and the stink from customer complaints!
