Lads, why did none of ye tell me about the EPA maps!??!!?
I had a poke off the radon map and discovered so much more! There's noise pollution (in cities greater than 100k so Limerick, Cork and Dublin), ecological risk to waterways etc, bedrock, waste facillities, etc. Very cool!! So many layers you really shouldn't try to turn them all on.

and click on the bar on the top to find the layers by category.
