I've been trying to find a map of the US showing arsenic in ground water. I've found articles with maps, and images in Google searches, but I can't download the maps from those, so I went to the source: usgs.gov. The site seems to work using Chrome, until I try to find maps. I am repeatedly given error messages or the searching on that site doesn't provide any arsenic maps. All I'm looking for are US maps of arsenic levels in ground water.
Here is an article with examples of the USGS maps. But I can't find the original maps on the USGS website. I'd like to be able to search the original maps by state and county.
