This year we've made all results from 2012-2016 downloadable and viewable in Google Earth.  Clicking the link below or the image to the side will prompt the download of the .kml file but you will need have Google Earth installed to view it.  Once opened, click the link on the main folder to view the report, click individual sites to view further details and use the slider to see results over time.  Please note exact sample collection site information is not available so sites are plotted to the nearest city or area.
