This map shows water systems included in the EPA’s records, as of Nov. 9. It’s based on boundaries developed by SimpleLab, a water-testing company. Click on a system to see the number of pollutants detected at or above the EPA’s minimum reporting levels and by what percent they exceeded those limits.
The map shows contamination in Berlin and Salisbury. However nothing in Baltimore. I don’t believe the map to be accurate since the were at least 2 chemical plants in Baltimore City (WR Grace and FMC) not to mention Bethlehem Steel, Sparrow Point Ship Yard, Dap, Kenny Kott Copper, General Motors assembly plant, Glidden Paint, etc, in Baltimore County.
