Princeton vs Atlantic City Water Quality
Side-by-side water quality comparison for two New Jersey cities.
If you are comparing Princeton and Atlantic City water quality - whether moving, choosing between the two, or curious about a relative's water - here is what the data shows.
Hardness comparison
Princeton has somewhat harder water at 70 PPM versus Atlantic City at 25 PPM, a difference of 45 PPM. Atlantic City residents generally do not need any water softening equipment.
Water sources and why they differ
Water sources differ: Princeton draws from Delaware River + local wells, while Atlantic City uses Kirkwood-Cohansey Aquifer. Both use similar source types, but local geology creates the hardness variation.
Contaminant concerns
PFAS contamination is a concern in Atlantic City (PFOA at 4.5 ppt, above the EPA limit of 4 ppt each). A reverse osmosis system or NSF P473-certified filter is recommended for drinking water.
