Crestwood Water Report Card
Here's what Crestwood's own water reports say, in plain English. Green means it looks good. Yellow means keep an eye on it. Red means it needs attention.
ppb = parts per billion. 1 ppb is about 1 drop of water in a backyard swimming pool.
The short version
- A little lead found in tested homes (under the action level)
- Chlorine by-products (TTHM) found, under the legal limit
- Pipe list not posted online
- Most homes were built before lead solder was banned (1986)
Lead in tested homes
Lead · 90th percentile
Keep an eye on it
The town tests tap water in homes most likely to have lead. 9 out of 10 of those homes had this much or less.
2.1 ppb
parts per billion
Crestwood: 2.1
Health goal: 0Action level: 15
Action level: if more than 1 in 10 tested homes go over this, the town must take extra steps.
A small amount was found: 2.1 ppb. That's under the 15 ppb action level, but the EPA's health goal for lead is 0.

Chlorine by-products
Total trihalomethanes (TTHM)
Keep an eye on it
Leftovers that form when chlorine cleans the water. The law limits them because drinking too much over many years may raise health risks.
52 ppb
parts per billion
Crestwood: 52
0Legal limit: 80
Legal limit: the most the law allows.
Highest single test: 62 ppb
Under the 80 ppb legal limit, but it's there. A certified filter can lower it at your kitchen sink.

Lead water pipes from the street
Service-line inventory
Keep an eye on it
A service line is the underground pipe that brings water from the street into a building. Some old ones are made of lead.
The Village of Crestwood reports it has developed a service line material inventory; residents can request a copy from the Village at 708-371-4800 x2003.
The pipe list isn't posted online. We can help you check your address.

Older homes
Homes built before 1980
Keep an eye on it
Lead solder and lead pipes were allowed in homes until 1986.
60.6%of Crestwood homes were built before 1980 — about 6 in 10Homes built before 1986 can have lead solder or lead pipes inside, even when the street pipe is fine.

For lead, the EPA's health goal is 0 — there's no amount known to be safe.
These are town-wide results. What comes out of your tap also depends on your own pipes and faucets.

COMMON QUESTIONS
Questions Crestwood homeowners ask
Is Crestwood's water unsafe?
We do not make that claim. Village of Crestwood reports results against federal standards in its consumer confidence report. Our work starts when you want more than the system-wide minimum—for taste, hardness, or a lower contaminant level than the legal limit allows.
What does the free Crestwood water report include?
Your town's published water-quality figures in plain English, what they mean for a home like yours, and which system (if any) addresses each result. No purchase is required.
What does the starting price include?
Equipment, standard installation by a properly licensed plumbing contractor, bypass where applicable, setup, and commissioning—assuming accessible piping, suitable drain and power, and normal working clearances. The written quote lists your exact scope.
Do you pay for referrals?
Yes. Refer a neighbor who installs with us and you receive $100 for a single system (RO, whole-home carbon, or softener) or $200 for a City Water Duo or Complete Home System, paid after their installation is complete and their 3-business-day cancellation window has passed. There is no limit on referrals.
How do you handle lead questions?
For lead, the EPA's health-based goal is zero. We specify drinking-water systems by their certification listing and include the applicable NSF/ANSI 58 or 53 documentation with your written quote. Testing your own water is always the first step we suggest.
