marianne, I am still having a hard time with some of
the water issues and have looked for answers. The one
thing that keeps standing out is high sodium content
but many cities are supposed to limit that. I did have
that number.
Hard water contains disolved hardness materials. These
are commonly calcium, manganese and magnesium. PPM or
GPG is parts per million or grains per gallon. 17.1
PPM ='s 1 GPG. Hard water scums. If you water hardness
is over 3 GPG's you can soften it. A water softener
collects hardness ions via pellets or beads. Once the
pellets are covered with hardness ions the reverse
flush using sodium water removes those ions and the
process starts over. Do you notice anywhere there are
drips any discoloration such as red, or blue/green?
Low sodium water should be under 10Mg/L and iron,
manganese and copper < 0.02 ppm. When I was in Florida
you could hardly keep the iron scum from staining
everything it touched. In Georgia at my old house the
green/blue collection was from copper minerals.
Neither effected the process I used but I had some
filtration going on and I used chemicals for
biological contaminate control.
This means that if your water supply contains more
than these metals shown above they do not evaporate
out and add to the oxide levels in trace ammounts. Not
usually enough to visually notice from my own
experience. But perhaps the sodium is more the issue.
So hard water users may see more problems than soft
water users. Who out there has seen this kind of
problem with glazes based on your water hardness? For
every grain of hardness in your water, your local
treatment plant most likely has increased the sodium
content by 7.5 Mg/per quart through ion exchange
method. Now isn't this all good news for those with
high blood pressure such as myself. Hmmmm. Get the
salt out. There is supposed to be limits on sodium
ammounts in drinking water. Supposed is our 'key' word
for today. Contaminates will increase as our pollution
factor increases and the threshold levels will
decrease because they can't have it both ways at all
times and make money. I believe Louis has convinced me
more that sodium is the culprit since my thought
processes moved from sediment minerals to something
more common.
