About Bear Water Purification
Northeast Illinois drinks Lake Michigan water, which is moderately hard. The bigger issue in older neighborhoods is lead. Illinois has more lead service lines than any other state, and replacement will take years.
Downstate is different. Glacial aquifers give hard water, and wells in farm country can carry nitrate. Reverse osmosis system installation reduces lead and nitrate when the system is certified for both. Bear Water Purification connects Markham, IL homeowners with plumbers for under-sink RO, RO filter changes and membrane replacement. Cold winter feed water slows output, so tank size gets checked too. Call (833) 879-3600 for water purification systems.
