Ada, SD
Contamination score
Higher = more contaminated vs. other cities.
Ada could not be confirmed as an active, documented community within Marshall County's list of unincorporated places, and no population or water-system data was found. No contamination incidents are documented. Given the uncertainty and rural northeastern South Dakota's generally low industrial pollution burden, a modest baseline estimate is used.
