Straight-from-the-sky rain sample from 1st November, 2018, 11pm in South Australia.

Taken at very beginning of a very unusual storm, i.e. loudest thunder anyone in the area ever remembers hearing, and then rumbling thunder & lightning, literally non-stop throughout the night.

I know this was not the best time to take a sample, but we'd had so little rain...for so long.

Results:

Aluminium:
'Safe' level = below 0.1mg/L
Mine = 0.0936mg/l [i.e. 93.6 ug/l]

Barium:
'Safe' level (WHO) = 0.7mg/L
Mine = 0.00409mg/L [i.e. 4.10 ug/l]

Strontium:
'Safe' level = 1.5mg/L
Mine = 0.0211mg.L [i.e. 21.1 ug/l]

Sulphur:
'Safe' level = ?
Mine = 2.4mg/L [i.e. 2400 ug/l]

If anyone has any feedback regarding above results, it would be very welcomed!
