Lansing, Michigan — the state capital with roughly 113,000 residents — has a water quality story that sits in the long shadow of Flint. That city’s lead contamination crisis, just 60 miles to the east, fundamentally changed how Michigan thinks about drinking water. And for good reason: many of the same conditions that created Flint’s disaster exist in cities across the state, including Lansing.
But Lansing’s story is its own. It’s about a city proactively addressing lead risks, navigating emerging PFAS concerns, and managing a water system in a state where public trust in water utilities was shattered.
Lansing’s Water Source: Groundwater
Unlike Flint (which draws from surface water), Lansing’s drinking water comes entirely from groundwater — a network of deep wells tapping into the Saginaw Formation aquifer system. The Lansing Board of Water & Light (BWL) operates 28 wells across the region.
Groundwater sources offer some advantages. They’re naturally filtered through rock and sediment, typically have lower turbidity and organic matter, and are less susceptible to the day-to-day fluctuations that affect rivers and lakes.
But groundwater isn’t risk-free. The aquifer chemistry matters — and in Lansing’s case, the water is naturally corrosive, meaning it can dissolve metals from pipes if not properly treated with corrosion control chemicals.
Lead: The Post-Flint Reality
After the Flint crisis erupted in 2014-2015, Michigan passed some of the strictest lead-in-water regulations in the country. The state’s revised Lead and Copper Rule reduced the action level from the federal 15 ppb to 12 ppb, with a goal of reaching single digits.
Lansing has thousands of lead service lines in its distribution system. The BWL has been working on an inventory and replacement program, as required by both Michigan regulations and the federal Lead and Copper Rule Revisions.
Key facts about lead in Lansing:
- The BWL operates a corrosion control program using orthophosphate to create a protective coating inside pipes and reduce lead leaching. This is the same type of treatment whose absence caused the Flint crisis
- 90th percentile lead levels have remained below Michigan’s 12 ppb action level in recent testing rounds
- Individual homes can still test high — corrosion control reduces lead leaching system-wide, but homes with lead service lines or lead solder always carry some risk
- Michigan’s lead service line replacement requirement mandates utilities replace all lead lines. The timeline is aggressive, but the scope is enormous
The Flint crisis made one thing absolutely clear: corrosion control is not optional, and switching water sources or treatment chemistry without understanding the impact on pipe corrosion can be catastrophic. Lansing’s BWL has been proactive about maintaining its corrosion control program, and that proactiveness matters.
PFAS: Michigan’s Statewide Problem
Michigan has more identified PFAS contamination sites than almost any other state. The state’s military bases, airports, industrial facilities, and fire training areas all used AFFF firefighting foam containing PFAS compounds.
In the Lansing area, PFAS concerns include:
- Former fire training sites where AFFF was used
- Industrial facilities that used or manufactured PFAS-containing products
- The Capital Region International Airport, where AFFF use for training and emergency response may have contaminated soil and groundwater
Michigan established some of the earliest state-level PFAS drinking water standards, setting MCLs for seven PFAS compounds in 2020. These standards, in some cases, are stricter than the 2024 federal standards.
The BWL monitors for PFAS across its well network. Some wells have shown detectable PFAS levels, though the system has maintained compliance with Michigan’s standards through well management and blending strategies.
For residents concerned about PFAS, it’s worth knowing that:
- Activated carbon filtration and reverse osmosis both effectively reduce PFAS in drinking water
- Michigan’s PFAS Action Response Team (MPART) tracks contamination sites statewide — their data is publicly available
- Private well owners near known contamination sites should test specifically for PFAS
What EPA and State Data Show
Compliance data from EPA ECHO and the Michigan Department of Environment, Great Lakes, and Energy (EGLE) shows:
- Lead and copper — Compliant with Michigan’s stricter standard, with ongoing service line replacement
- PFAS — Monitored across all wells, managed within state MCLs
- Nitrates — Generally low in Lansing’s deep wells, though surrounding agricultural areas affect shallower aquifers
- Radium — Some Michigan groundwater contains naturally occurring radium from the sandstone aquifer. Lansing monitors and manages levels through well selection and blending
- Arsenic — Naturally present in some Michigan aquifers. The BWL’s wells have generally tested below the 10 ppb MCL
Lansing vs. Flint: Important Differences
It’s natural for Lansing residents to wonder: could what happened in Flint happen here? There are important differences:
Different water source. Flint’s crisis was triggered by switching from treated Detroit water to improperly treated Flint River water. Lansing has used the same groundwater sources for decades with consistent treatment.
Maintained corrosion control. Flint’s crisis occurred because corrosion control treatment was not applied after the source switch. Lansing’s BWL has maintained its orthophosphate program.
Different governance. Flint was under emergency management when the disastrous decisions were made. Lansing’s water system operates under normal municipal governance with public oversight.
Same underlying risk. Both cities have lead service lines. Both cities have aging infrastructure. The physical vulnerability is similar — the difference is in how it’s managed.
None of this means Lansing residents should be complacent. It means the system is currently being managed appropriately, and the post-Flint regulatory environment provides additional safeguards.
What Residents Can Do
- Get your water tested. The BWL offers lead testing. If you have a lead service line, test annually at minimum.
- Check if your line is lead. The BWL maintains a service line map. Look up your address. If your line is lead, find out when replacement is scheduled.
- Run your tap. If water has been sitting for hours, run cold water for 30 seconds to two minutes before drinking.
- Use certified filters. NSF/ANSI 53-certified filters reduce lead effectively. For PFAS, look for NSF/ANSI 53 or 58 (reverse osmosis) certified systems.
- Never use hot tap water for cooking or formula. Hot water leaches more lead from pipes.
If you’re concerned about your water quality, a certified water treatment professional can test your water and recommend treatment solutions specific to your situation.
Home Treatment Options
- Point-of-use reverse osmosis — Most comprehensive option, removing lead, PFAS, radium, nitrates, and most contaminants
- Carbon block filters — Effective for lead, chlorine, and some PFAS compounds. More affordable than RO
- Whole-house systems — Address sediment, iron, and hardness (Michigan’s groundwater tends to be very hard)
- Water softeners — Common in Lansing due to hard water; note that softeners alone don’t address lead or PFAS
