Is the tap water in Schererville, IN safe to drink?
Schererville's municipal water meets federal Safe Drinking Water Act standards, but "meets standards" doesn't mean "perfectly clean for your home." Old pipes, plumbing materials, and local ground conditions can introduce lead, chlorine byproducts, or bacteria between the treatment plant and your faucet. A professional water quality test gives you an actual picture of what's coming out of your tap.
Do I need water testing if I'm on city water — not a private well?
Yes. Municipal treatment handles most contaminants at the source, but it can't control what happens inside your home's plumbing. Homes built before 1986 in Lake County often have lead solder or older galvanized pipes that leach metals after water leaves the main. Testing your water at the tap — not just the source — is the only way to know what you're actually drinking.
What does a home water quality test check for?
A standard residential water test screens for bacteria (coliform and E. coli), lead, nitrates, hardness, pH, chlorine levels, and common volatile organic compounds (VOCs). Depending on your property — city water or private well — additional tests for arsenic, radon in water, iron, or manganese may be recommended. Results come back as clear numbers, not vague pass/fail grades.
Below is a closer look at what water testing in Schererville and the surrounding Lake County area actually looks like, why the municipal-versus-well distinction matters, and what Hawk Home Inspection checks for you.
Why Lake County Water Conditions Make Testing Worth It
Lake County sits on a mix of glacial geology — sandy soil near the Indiana Dunes corridor, heavier clay further south toward Dyer and Schererville. That geology shapes what contaminants naturally migrate toward groundwater. Meanwhile, the urban and industrial history of the county's northern cities (Hammond, Gary, East Chicago) means legacy contamination in older infrastructure is a real concern, not a hypothetical one.
The U.S. EPA's Safe Drinking Water Act sets maximum contaminant levels, and Indiana American Water publishes an annual Consumer Confidence Report for Schererville's service area. But those reports reflect the water leaving the plant — they don't account for your specific pipes, your water heater, or any service line running from the street to your front door.
If your home was built before 1986, lead solder in the plumbing is a real possibility. The EPA estimates that lead service lines and plumbing materials are the primary source of lead exposure in drinking water across older American neighborhoods. That's not alarmist — it's just how the infrastructure was built.
Municipal Water vs. Private Well Water: What's Different About the Risk?
Most Schererville residents are on municipal water. But parts of unincorporated Lake County — and neighboring Porter County communities — still rely on private wells. The risks and the testing approach are genuinely different.
- Municipal (city) water: Treated and monitored, but pipe condition inside your home is your responsibility. Primary concerns: lead from older plumbing, chlorine disinfection byproducts (THMs), and bacterial regrowth in low-flow sections of the distribution system.
- Private well water: No ongoing treatment. Entirely your responsibility to test. Primary concerns: coliform bacteria, nitrates (especially near agricultural land), iron, hardness, and naturally occurring arsenic from bedrock.
- Older homes on either source: Galvanized steel pipes corrode over time and can release iron, manganese, and sediment regardless of what the source water looks like.
Municipal vs. Well Water: Key Testing Differences
| Factor | Municipal (City) Water | Private Well Water |
|---|---|---|
| Treatment | Treated at source; monitored by utility | No treatment; homeowner's responsibility |
| Top contaminant risk | Lead from internal pipes; disinfection byproducts | Bacteria, nitrates, arsenic, iron |
| Testing frequency | At purchase; after plumbing changes | Annually recommended by Indiana DNR |
| Who's accountable | Utility owns main line; you own interior plumbing | Homeowner owns everything |
- Treatment: city water is treated at the source; well water gets no treatment unless you install it yourself.
- Top risks: lead and disinfection byproducts for city water; bacteria, nitrates, and arsenic for wells.
- Testing schedule: city water at purchase and after plumbing work; private wells ideally every year.
- Accountability: your utility owns the main; you own your interior pipes — and your well entirely.
When Should You Schedule Water Testing?
A few situations make water testing a smart call, not just a nice-to-have:
- You're buying a home in Schererville, Crown Point, or anywhere in Lake County — especially pre-1986 construction.
- You've noticed a sulfur smell, rusty or cloudy water, or a metallic taste from the tap.
- You have a newborn, are pregnant, or someone in the household is immunocompromised.
- You recently had plumbing work done or your area has had a water main break nearby.
- You're purchasing a home with a private well anywhere in Porter or LaPorte counties.
Real estate transactions are the most common trigger. Lenders and buyers both benefit from knowing the water quality before closing — and that's where having a certified inspector who can pair Water Inspection with a full Residential Inspection saves everyone a second trip and a second scheduling headache.
Quick Checklist: Reasons to Test Your Water Now
- Home built before 1986 (lead solder risk)
- Private well with no test in the last 12 months
- Buying or selling a home in Northwest Indiana
- Unusual taste, smell, or color in your water
- Recent plumbing replacement or nearby main break
- Infant, pregnant household member, or immune-compromised resident

What Hawk Home Inspection Does Differently
Hawk Home Inspection has been serving Schererville and the wider Northwest Indiana area since 2014, and the team brings over 40 years of combined inspection experience to every job. With 600+ inspections per year and a 4.8-star average across more than 425 verified reviews, the track record here is straightforward.
What clients consistently mention: you get a plain-English report the same day, with photos, that actually explains what was found — not a jargon-filled checklist you need a contractor to decode. You're also encouraged to attend the inspection so you can ask questions and walk away knowing exactly what your water results mean for your family.
Water quality testing is one of eight services Hawk offers under one roof. That matters because water concerns rarely show up alone. A home with aging galvanized pipes might also have indoor air quality concerns — and being able to add Air Quality Testing to the same appointment saves you time and gets you a more complete picture of the home. You can see all available Services on the Hawk website.
All estimates are free. There's no obligation to book until you're ready.

Frequently Asked Questions
How long does a water quality test take, and when do I get results?
Collecting the water sample at your home takes about 15–20 minutes. Lab turnaround varies by the tests ordered — basic panels (bacteria, lead, nitrates) typically return results within 2–5 business days. Hawk provides a same-day digital report summarizing findings once results are in, written in plain language so you don't need a chemistry degree to understand them.
Is water testing required when buying a home in Indiana?
Indiana does not require water testing for home purchases on municipal water by state law, but many lenders require it when a property has a private well. Even if it isn't required, testing before closing is strongly recommended — especially in older Lake County neighborhoods where lead plumbing is common. It's one of the easiest things to know before you're locked into ownership.
What contaminants are most common in Northwest Indiana well water?
In Porter and LaPorte county rural areas, coliform bacteria and nitrates from agricultural runoff are the most frequently detected issues in private well water. Iron and hardness are also common throughout the region. Arsenic occurs naturally in some bedrock aquifers. A full well water panel tests for all of these plus pH, hardness, and volatile organic compounds to give you a complete picture.
Can I buy a home test kit at the hardware store instead?
Hardware store strip kits check for a narrow range of contaminants at low sensitivity levels — they're better than nothing but not reliable enough for a real estate transaction or a health decision. A certified lab test, collected by a professional inspector, is accepted by lenders, gives you legally defensible results, and actually detects contaminants like lead and bacteria at the concentrations that matter for your family's health.
Does Hawk Home Inspection test water as a standalone service, or only with a full home inspection?
Water quality testing is available as a standalone service — you don't need to book a full inspection to get your water tested. That said, many clients in Schererville and surrounding Lake County communities combine water testing with a residential or pre-listing inspection to get everything done in one visit.
