The latest Deerfield Annual Drinking Water Quality Report 2024 says Deerfield'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

What Deerfield's report lists

  • The 2024 report lists total hardness at 140 ppm as CaCO3, with a 2024 sample date.
  • The 2024 report lists total trihalomethanes (TTHM) with a highest running annual average of 48.3 ppb, an 80 ppb MCL, and no violation.
  • The 2024 lead-and-copper table reports a lead 90th percentile of 0 ppb and zero sites over the lead action level.

Hardness has no EPA health limit. It is mainly useful for discussing scale, fixtures, soap use, and how water feels in daily use.

This is a system-wide municipal report, not a measurement of water at a particular Deerfield home. Plumbing, fixtures, treatment equipment, and sample location can affect conditions at the tap; assess the home before selecting equipment.

Treatment Options

Treatment options for Deerfield homes

A system should follow the conditions and priorities at the home—not assumptions drawn from a community-wide report.

  • Whole-home water softenersFor homes that want to address mineral-related hardness; configuration follows an in-home assessment.
  • Whole-home carbon filtrationAn option to consider for taste, odor, or chlorine preferences after reviewing the home’s goals and setup.
  • Salt-free conditioningAn alternative for selected applications when it fits the plumbing and the homeowner’s objectives.
  • Well-water treatment evaluationConsidered only after laboratory results or a confirmed on-site field test; Deerfield’s municipal report is not a well-water test.
  • Kitchen reverse osmosisTank and tankless kitchen reverse-osmosis options are available only as an add-on to a whole-home installation.

Where does Deerfield’s drinking water come from?

The Village says Deerfield purchases water from the City of Highland Park, whose treatment facility collects and processes Lake Michigan water. That supply information is useful context, while the water at an individual home can still be affected by that home’s plumbing and fixtures.

What does Deerfield’s 2024 report say about hardness?

The 2024 Annual Drinking Water Quality Report lists total hardness at 140 ppm as CaCO3. A whole-home softener decision should also consider the homeowner’s experience, plumbing, fixtures, and an evaluation at the property.

Do the report’s results describe the water at my Deerfield tap?

Not necessarily. Deerfield’s report is a system-wide municipal report. It is not proof of conditions at one home, where plumbing, fixtures, sample location, and existing equipment can affect tap-water conditions.

Does Deerfield’s report mean I need carbon filtration or reverse osmosis?

No. The 2024 report lists a highest TTHM running annual average of 48.3 ppb, below the 80 ppb MCL and with no violation, but it does not prescribe equipment for a particular home. Whole-home carbon filtration may fit taste, odor, or chlorine preferences, while kitchen tank or tankless reverse osmosis is offered only with a whole-home installation.
