Reverse Osmosis Systems
in Dearborn, MI

Yes. Reverse osmosis is one of the most effective ways to reduce lead at a single tap, and Culligan reverse osmosis systems are certified for lead reduction. That is especially useful in Dearborn, where lead results varied widely from home to home and the city is still working through thousands of lead service lines. Copper, which also comes mainly from household plumbing, had a 90th percentile of 0.3352 ppm, with one sampled home above the 1.3 ppm action level; RO reduces copper as well.

Start with the city’s service line inventory and water department, which can tell you what is recorded for your address. Lines of unknown material are being treated as lead. While you wait on replacement, a free in-home water test from Culligan shows what is actually coming out of your tap, and an under-sink RO system gives you filtered water for drinking, cooking and baby formula.

Reverse osmosis is among the most effective home treatments for PFAS. In Dearborn’s most recent report, federal UCMR 5 testing found PFOA, PFOS and the other PFAS compounds below reporting limits at both GLWA plants. Michigan limits PFOA to 8 ppt, PFOS to 16 ppt and PFHxS to 51 ppt, and the federal limit for PFOA and PFOS is 4 ppt. An RO system adds a layer of protection if levels in the source water ever change.

Yes, chromium six (or hexavalent chromium) has recently been discovered in limited amounts in some water supplies. Chromium six is suspected of being a carcinogen, and should not be ingested at amounts above the federally mandated limits.  We have never been alarmists, but if you are concerned about the quality of the water you drink, you might want to consider a reverse osmosis system.  Reverse Osmosis is the only readily available system that removes up to 97% of Chromium-6. You can read more about it here.

Reverse osmosis is a sophisticated multi-stage filtration system that is capable of removing up to 97% of all the dissolved minerals from your water.  It is designed to make water that is at least as good as the water you buy in bottles.  Many times, it’s even better.  This reduces waste in landfills by using less bottled water, making reverse osmosis environmentally friendly.

Yes – The Culligan RO system uses multiple processes including Reverse Osmosis to make great tasting, low sodium drinking water. Reverse Osmosis removes about 97% of the TDS (Total Dissolved Solids) including salt and sodium from the water. Read the labels on bottled water and you will discover reverse osmosis is the same process used by most bottlers … so in effect … you really are getting … “bottled water without the bottle”.

Yes, reverse osmosis reduces fluoride along with other dissolved minerals. Fluoride is added during treatment, and the most recent report shows 0.66 ppm from the Southwest plant and 0.49 ppm from Springwells, both well below the 4 ppm limit. If you prefer to keep fluoride in your drinking water, your Culligan expert can walk you through the options.

Refrigerator filters are typically just carbon, and while carbon filtered water is better than no treatment at all, it is limited in what it can remove. Only reverse osmosis is capable of removing dissolved minerals and chemicals from your water. 

Yes. Culligan offers reverse osmosis filtration rental in Dearborn, with installation, filter changes and service included, which makes it easy to add lead-reducing drinking water while the city works through line replacement.
