Flint Lead Testing Map

This map on michiganradio.org  from February 1st, depicts the results of home lead tests in Flint. The test information, gathered by the State, was then grouped into the following categories to make this map:

  • 0 ppb – no lead detected in the drinking water
  • 1-4 ppb – the EPA deems this range as acceptable
  • 5-14 ppb – exposure is a concern, but still below an EPA “federal action level”
  • 15-49 ppb – a range above the federal action level for lead, but can be treated by filters
  • 50-149 ppb – reaching dangerous levels, but can be treated by filters
  • 150 and above – a range at which the federal government says water filters might not workScreen Shot 2016-04-28 at 11.02.29 AM.png

Looking at this map, trying to determine the source is difficult because no real pattern can be determined. Makes you think about what other areas in the US have horrible water that either hasn’t been discovered yet, or just taken seriously.

Thanks Michigan Radio for the map! All information from michiganradio.org

Marine Debris in Cordova Alaska

A new project has been set up for marine debris mapping in Cordova, Alaska. This is a community map which means that anyone in the area who see debris on the land or water can photograph, pin-point, and share with anyone through the site. Using Mappler, you just add the location you found the debris and then choose what kind of debris it is from the long list of options (there is also an option for unknown). You can also add in the time and date, additional comments, and the length of the debris.

If you are ever in the Cordova area or around the Gulf of Alaska make sure to post what debris you find! This will help with cleanup and pollution monitoring !
