Streamwood water treatment
The latest Village of Streamwood Annual Drinking Water Quality Report says Streamwood's public water system met the standards described in that report. A utility report describes the public system. It is not a reading from one home's tap, where plumbing, fixtures, sample location, and existing treatment can change the experience.

LOCAL WATER NUMBERS
Hardness has no EPA health limit. It is mainly useful for discussing scale, fixtures, soap use, and how water feels in daily use.
This Consumer Confidence Report describes the municipal water system and reported sampling results. It does not determine water conditions at an individual home, which can be affected by building plumbing, service-line material, fixtures, sample location, existing equipment, and local conditions.

HOMES IN THIS AREA
The 2020-2024 ACS estimate puts the median year built for Streamwood housing units at 1981, a late twentieth-century housing era. That is context for discussing plumbing access, fixture age, and updates at a specific address, not a condition report for any one home.

Town FAQ source: Village of Streamwood Annual Drinking Water Quality Report (2025)
The Village report says Streamwood purchases surface water from the City of Chicago, sourced from Lake Michigan. That system-level supply information is useful context, while water at an individual home can still be affected by that home’s plumbing and fixtures.
The report lists typical water hardness at 8 grains per gallon, or 128 to 144 mg/L (ppm) as CaCO3. A whole-home softener decision should also consider the homeowner’s experience, plumbing, fixtures, and an evaluation at the property.
Not necessarily. Streamwood’s report is a municipal, system-wide report. It is not proof of conditions at one home, where plumbing, service-line material, fixtures, sample location, and existing equipment can affect tap-water conditions.
The report says the Bartlett interconnection and emergency wells were activated for approximately three days in 2025. It also says the Bartlett report and well-water sample data are not included in the report and are available by request from the Village.
