They still do as it's harmless, you can make it on site and it's
cheap.

Resistivity of > 10Mohm/cc is practical, > 20Mohm/cc is doable and
< 2Mohm/cc is too poor to use.

It's strange to watch water cascade out from behind the panels of
a transmitter and wonder if there's enough water left to finish the
transmission.
