West Bloomfield’s drinking water comes from West Bloomfield Township (EPA system MI0006975), which buys treated surface water from a neighbouring wholesale system and distributes it locally for about 49,479 people. This page translates that system’s official EPA record — lead and copper results, violation history, and what the data does and does not say — into plain English.
This page is built entirely from the U.S. EPA’s Safe Drinking Water Information System (SDWIS), the same records state regulators use. We did not test West Bloomfield’s water, and system-level data describes the utility’s water as a whole — not what comes out of one specific home’s tap. Where the record is silent, we say so rather than guess.
Key takeaways
- West Bloomfield Township supplies West Bloomfield (Purchased surface water); it serves about 49,479 people across its service area.
- In the most recent sampling reported to the EPA, West Bloomfield Township’s 90th-percentile lead result was not detected — reported as 0 ppb against an EPA action level of 15 ppb.
- No health-based violations in the last 10 years of EPA records for West Bloomfield Township.
- EPA does not track hardness. If you’re shopping for a softener, test first and size from a real grains-per-gallon number.
The water system serving West Bloomfield
West Bloomfield Township is the community water system the EPA associates with West Bloomfield, Michigan. It reports a population served of about 49,479. Its EPA source code is a purchased one: the system buys already-treated water from a neighbouring supplier rather than treating its own, which is common for suburbs and townships.
| System | EPA ID | People served | Source water | Role |
|---|---|---|---|---|
| West Bloomfield Township | MI0006975 | 49,479 | Purchased surface water | Main system |
EPA’s records associate 10 further systems with the West Bloomfield area beyond the ones above — neighbourhood districts, subdivisions and mobile-home parks among them. If your water bill names a different system, that name — not the city name — is the record to check.

Lead and copper
Lead: in the most recent sampling reported to the EPA, West Bloomfield Township’s 90th-percentile lead result was not detected — reported as 0 ppb against an EPA action level of 15 ppb.
Read those numbers carefully: a 90th percentile is a system-wide statistic from a sample of homes, not a test of your tap. Lead in drinking water comes mostly from a home’s own plumbing — service lines, solder and fixtures — so two houses on the same street can test very differently. Homes built before 1986 carry the highest risk, whatever the system average says.
Violation history — the last 10 years
EPA records show no health-based violations for West Bloomfield Township in the last 10 years. Health-based violations are the serious kind: a contaminant over its legal limit, a skipped treatment step, or a disinfectant level above its maximum.
Separately, EPA lists 2 monitoring/reporting items for this system in the last 5 years — missed or late tests and paperwork. Those are compliance-process findings, not contamination findings, and we keep them in their own bucket on purpose.
What this means for your home
System data sets the background; your home’s plumbing writes the foreground. In practice:
- Lead is a plumbing question, not a system alarm, here. The system’s own result is low, so the remaining risk sits in your home’s pipes and fixtures. A filter certified to NSF/ANSI 53 for lead is cheap insurance for older homes; our water filter guides explain the certifications without the marketing.
- Taste and smell: surface-water systems disinfect with chlorine or chloramine, which is most of what people taste. A basic carbon filter (NSF/ANSI 42) handles it; our chloramine vs chlorine explainer helps you tell which one your water has.
- Hardness is not in this record — by design. The EPA doesn’t track it, so nobody can honestly tell you your grains-per-gallon from this page. Scale on fixtures and shower doors is a hint, not a measurement. Test (strips are a start; a lab test is better — see how to test your water at home), then size any softener with our softener sizing calculator and the softener hub.
- On a private well outside the city system instead? Nothing on this page applies to your water — start with our Michigan well water guide for testing and treatment that fits the state.

Frequently asked questions
Is West Bloomfield water safe to drink?
On the evidence in its EPA record, yes: West Bloomfield Township has no health-based violations in the last 10 years, and its most recent 90th-percentile lead result was not detected, against an action level of 15 ppb. Health-based violations are the serious category — the contamination and treatment failures — so a clean 10-year record is the strongest signal the federal data offers. Two honest limits: EPA data describes the system as a whole, not your tap, and lead in particular usually comes from a home’s own plumbing — a certified home test is the only way to know your exact water.
Where does West Bloomfield get its drinking water?
West Bloomfield Township is the community water system the EPA associates with West Bloomfield. It buys treated surface water from a neighbouring wholesale system and distributes it locally and serves about 49,479 people across its service area (EPA system ID MI0006975).
What is the lead level in West Bloomfield’s water?
In the most recent sampling reported to the EPA, West Bloomfield Township’s 90th-percentile lead result was not detected (0 ppb), against an action level of 15 ppb. That is a system statistic from sampled homes, not a test of your tap — older home plumbing can still add lead on the last few metres, which is why a home test beats any average if your house predates 1986.
Has West Bloomfield’s water system had violations?
No health-based violations appear for West Bloomfield Township in the last 10 years of EPA records. It does carry 2 monitoring/reporting items in the last 5 years — paperwork findings, not contamination.
Do I need a water filter in West Bloomfield?
Nothing in West Bloomfield Township’s EPA record points to a problem you must filter for. Most households here who filter do it for taste (a simple carbon filter) or for lead insurance in older plumbing (NSF/ANSI 53). If you shop, match the certification to the job — and measure hardness before considering a softener.
