How might you explain the fact that Vermont and New Hampshire states with very low sulphur dioxide emission experience acid levels that are among the most severe in the country?

Vermont and New Hampshire's severe acid levels can be attributed to long-range transport of sulfur dioxide (SO2) and other pollutants from industrial regions, particularly from the Midwest and Northeast. Despite their low local emissions, prevailing winds carry these pollutants into the region, where they can react with moisture to form acid rain. Additionally, the region's sensitive ecosystems and geology, such as granite bedrock, may exacerbate the impacts of acid deposition, leading to higher acid levels in soil and water.
