Iron rich water

We live on the edge of the South Wales coal field. There are always Iron Oxide deposits associated with coal strata.

When it hasn't rained for a few days the Iron rich water running from natural springs leaves Ferric Hydroxide stains on the stones. The next heavy rain will wash all of it away and it will reappear in the next dry spell.
