West St. Paul Reverse Osmosis Drinking Water Systems
West St. Paul water is centrally softened by Saint Paul Regional Water Services (SPRWS) to roughly 5.3 grains per gallon. That is a good start, but it does not address chlorine, lead from aging pipes, PFAS, pharmaceuticals, or fluoride. AJ Alberts installs NSF-certified reverse osmosis systems that deliver premium drinking water at your kitchen tap.

Why West St. Paul Homeowners Choose Reverse Osmosis
Centrally softened municipal water is a real benefit for hardness, but it is not a complete water quality solution. Lime softening at the treatment plant addresses calcium and magnesium. It does not address chlorine and chloramines added for disinfection, lead and copper picked up from aging pipes between the plant and your tap, PFAS forever chemicals from regional contamination, pharmaceuticals that pass through wastewater treatment, fluoride added at the plant, or the increased sodium content that softening itself introduces. A reverse osmosis system at your kitchen sink is the most effective and most cost-efficient way to address every one of those concerns.
West St. Paul shares SPRWS water with Saint Paul and has a mix of mid-century and newer housing stock. The municipal treatment is excellent for hardness, but the same residual concerns (chlorine taste, aging pipes, PFAS surveillance, pharmaceuticals) apply. Reverse osmosis at the kitchen sink is the standard recommendation for homeowners who want premium drinking water.
A reverse osmosis (RO) drinking water system installs under your kitchen sink and produces dedicated drinking and cooking water that has been filtered to remove up to 99 percent of contaminants. RO removes PFAS, lead, arsenic, fluoride, chlorine, chloramines, pharmaceuticals, nitrates, sodium (the byproduct of softening), and hundreds of other dissolved compounds. The result is water that tastes cleaner, makes better coffee and tea, produces clear ice, and gives you and your family direct certainty about what you are drinking and cooking with.
What Reverse Osmosis Removes From West St. Paul Water
RO removes from your water:
- Chlorine and chloramines (taste and odor)
- PFAS forever chemicals (up to 99 percent)
- Lead from aging pipes (up to 99 percent)
- Arsenic, nitrates, fluoride
- Pharmaceuticals and personal care product residues
- Sodium (the byproduct of softening)
- Hundreds of other dissolved compounds
RO does not address:
- Hardness (calcium and magnesium) at every tap (a softener handles this; in West St. Paul that is not necessary for most homes given SPRWS central softening)
- Bacteria and viruses (municipal water is already disinfected; well water needs UV)
- Iron and manganese (a dedicated iron filter handles this where needed)
