The square for Lead (Pb) on the periodic table.When you move to a new place there are things you think about because you know they will change (mailing address, insurance coverage and cost, and, if you are me, local elected officials).  There are other things you don’t think about because they are part of a cultural background and as a stranger in a strange land you don’t know they change (Every one eats at a Friday fish fry, Neighborhoods set days/times for Trick-or-Treating, and, if you are not me, local elected officials).  One thing I never considered when moving to Milwaukee was that my tap water might not be safe to drink.

It’s not.  My tap water has lead in it.

A Service Line Lined with Lead

I never considered my tap water might not be safe to drink because clean drinking water is an expected government service across the country.  Perusing Twitter recently, my state Senator tweeted a Milwaukee Journal Sentinel article stating the Milwaukee Health Department will distribute free water filtration devices to residents living in homes with water service lines made of lead.  When I visited Senator Lena Taylor’s office last month her staff had told me lead poisoning was a key issue for her given some Milwaukee children have higher blood lead levels than Flint, Michigan.  As a public health advocate and former employee of the Minnesota Department of Health, I was familiar with the dangers of Lead poisoning and was curious what MKE neighborhoods have lead service lines, so I called the Health Department.

Illustrating the Problem

Talking with a friendly Health Department employee, she informed me my house does have a lead service line.  The City maintains a list of properties with lead service lines and my home is one of the 70,000 odd in the city built with such lines.  Water service lines connect the water main owned by the municipality to the residence, business or property.  In Milwaukee, the City owns the service line from the curb stop to the property and the property owner owns the line from there on in.

Originated at Milwaukee Public Works website

Having a lead service line means that even though clean water is coming from the treatment facility through the water main, lead could leech and contaminate water at an individual property.

The sheer scope of the lead problem, 70,000 in the Milwaukee Water Works service area, should have bothered me, but with my public health background, it didn’t.  Our country has not done as much as we should to mitigate our legacy of lead use.  For MKE, the 70K properties constructed before 1947 have lead service lines, and an additional 10,000 constructed between 1948 and 1951 likely have lead service lines.  Buildings constructed after 1951 have service lines made of copper.

It did not bother me that my home might have a lead problem.  It bothered me that I was unaware of the lead problem.  Little did I know Milwaukee’s lead legacy was just part of the whole.  The whole state of Wisconsin has a lead legacy.

Health Risks of Lead

Lead poses significant health risks.  The greatest risks are to infants, young children, and pregnant women.  Since lead affects the brain, though, the CDC has stated there is no safe level of lead exposure.  Zero.

Lead breaks down the body.

Exposure to high levels of lead may cause anemia, weakness, and kidney and brain damage.  Exposure is worrisome, as after lead is absorbed it is stored in bones, blood, and tissues and results in continual internal exposure.  Generally, lead affects children more than it does adults.  Children tend to show signs of severe lead toxicity at lower levels than adults, and exposure can lead to damage to the brain and nervous system, slowed growth and development, learning and behavioral problems, and hearing and speech problems.  According to the CDC, the medical and special education costs resulting from child lead exposure can be $5,600 per child.

Numbers Affected

Today approximately half a million U.S. children ages 1-5 have blood lead levels high enough to damage their health.  Additionally, approximately 24 million homes have elevated levels of lead in house dust (resulting from deteriorated lead paint).

Mitigating Lead Exposure

Given lead’s dangerous health risks, there are steps you can take to reduce lead in your water supply.  These are from the Milwaukee Health Department’s website but awesome enough to replicate here.

Individual Actions

  1. Flush your plumbing. Before using tap water for drinking or cooking, flush your plumbing by running the kitchen faucet (or any other tap you take drinking or cooking water from) on cold for a minimum of three minutes (or longer if necessary) until the water is noticeably colder. This is especially important if your water has been sitting in your pipes for more than six hours. To conserve water, you can use this excess for watering household plants or outdoor plants. Showering, doing laundry and flushing the toilet all help clear water from the pipes. Bathing, showering, and doing laundry in water from lead services lines or lead plumbing is safe.
  2. Use only cold water for cooking and drinking. Water from the hot water tap can dissolve more lead quicker than cold water. Boiling water will not reduce the amount of lead in your drinking or cooking water. You can also consider purchasing bottled water for drinking and cooking from a known lead-free source.  You may also want to consider filling a clean container(s) with water from the flushed tap, and reserving this water for drinking, cooking, or other consumption.
  3. Inspect your faucet aerator. The aerator on the end of your faucet is a screen that can catch debris, including particles of lead. It is recommended to periodically remove the aerator and rinse out any debris.
  4. Purchase a home filtration system. Home drinking water filtration systems or water filtering pitchers can reduce or eliminate lead. Be sure to look for products certified by NSF/ANSI under Standard 53 for removal of lead and follow any manufacturer’s guidelines on installation and maintenance of the product. Find a list of products at http://www.nsf.org/ or download information here.
  5. Replace your lead service line or interior plumbing. A licensed plumber will be able to determine if your home’s interior plumbing and fixtures and/or service line are made of lead. Replacement must be done by a licensed plumber under contract from the homeowner.

Additional Actions for Parents and Expectant Mothers

In addition, any households with residents or visitors that include children under the age of 6, pregnant and breastfeeding women should also:

  1. Only use bottled water from a known lead-free source or cold, filtered tap water (use an NSF/ANSI Standard 53 certified water filtration device) to make formula, concentrated juices, and for cooking and drinking. If using water directly from the faucet, use only cold water that has been well-flushed for a minimum of three minutes.
  2. Have their blood lead level tested. The City of Milwaukee Health Department advises parents and health care providers to follow the “3 before 3” guidance by testing children for elevated blood lead levels three times before the age of 3. Consult your health care provider or the City of Milwaukee Health Department for further information.

Beyond Water

Here is additional information for mitigating the dangers of lead in homes (i.e. lead paint) and a primer on lead paint, lead in water and lead in soil.

Milwaukee’s Mitigation Efforts

As a citizen of Milwaukee – MKE – I began researching what my city was doing to mitigate lead’s harmful effects.  Thankfully, the Milwaukee Health Department has myriad programs to address the dangers of lead.  The city and community are also undertaking efforts pertaining to lead service lines.

Free Water Filtration Devices

(To find out if your home has a lead service line call the Milwaukee Water Works Customer Service Line at (414) 286-2830.)

There are two organizations partnering with the Health Department to distribute free water filtration devices.  The organizations are really advocating pregnant women and families with children and to get the devices, but they are eligible to anyone with a lead service line.

One of the devices attaches to the faucet (turn on facet, filtered water comes out), the other is a Brita pitcher on steroids.  If you are not eligible for a free device, through the end of the year, devices can be purchased at discount through Aquasana with the code: Milwaukee.  The discount is larger than other discounts on the site, so make sure to use your Milwaukee cred.

My Home Filter

I visited SDC to receive my free water filtration device.  They handed me the faucet model, an extra filter, and information on lead (the primer above).  With the extra filter my device should last one year (or 840 gallons) before needing to buy new filters.  Installation was less than a minute; I spent more time figuring out which side of the sink to put it on.  No complaints here on design hindering adoption – this is as slick as it gets.

The aerator’s not much bigger either.

Replacing Lead Pipes

Filtration is a good stopgap, but the source of contamination – the lead service lines – needs to be replaced.  According to the Milwaukee Journal Sentinel, earlier this week the MKE Finance & Personnel Committee advanced a proposal to mandate full service line replacement (both city and property sides) which would require a property owner to pay to replace their side of a service line when the City replaces the other side of the line.  This would occur in emergency situations — such as service line fails, leaks or other damage — or during a planned infrastructure project.

The proposal also contains cost sharing provisions for property owners.  The City would foot the whole bill for the City’s half of the lead service line, while covering two-thirds of the cost of replacing privately owned service lines if the owner agrees to have city contractors perform the work.  Costs would be capped at $1,600 for the property owner, over a 10 year payback.  The proposal will be heard before the full City Council on November 22nd.

Back in January the MJS reported the total cost to replace all lead service lines throughout the cite would be between $511 million to $756 million.  Milwaukee’s lead legacy is expensive.

Lead in Soil

Lead pipes in the ground and lead paint on homes will result in wider contamination than simply drinking water.  They also contaminate soil.  Contaminated soil is tracked into the home on shoes and clothes, children come into contact with contaminated soil as they play, and contaminated soil threatens personal and community gardens.  The organization Growing Healthy Soil for Healthy Communities, a partnership of health and community organizations, exists to increase safe residential gardening and reduce soil lead concentrations.  They run workshops on gardening and offer soil sample testing.

Wisconsin’s Lead Normalization

While the City of Milwaukee has the largest problem by volume, communities around the state have lead service lines affecting their drinking water.  The Wisconsin Center for Investigative Journalism estimates there are 176,000 lead service lines in Wisconsin.  The Wisconsin DNR was appropriated $14.5 million in funding to use in 2017-18 to assist property owners in replacing their half of a lead service line.  Given the costs in MKE alone come on the low end at $500 million dollars, this is a helpful, if small, amount compared to the statewide need. 

The more I looked into the problem of lead in Wisconsin the deeper, and more systemic the problem revealed itself to be.  Lead’s existence in the state has become normalized, a fact we are hopefully waking up from.

Lead in Your Community

Milwaukee and Madison’s efforts on lead service lines may be the most widely reported, but municipalities around the state are also effected.  A list of communities and the impact of lead service lines:

  • Appleton: 1% of service lines [GBPG]
  • Brown Deer: None [WISN]
  • Cudahy: ~30% or 1,500 service lines [WISN, Cudahy Water Utility]
  • Eau Claire: Cannot find data*
  • Fort Atkinson: Cannot find data, however, the Fort Atkinson Water Utility has a reference map of service lines.
  • Green Bay: < 5% or ~1,700 service lines  [Green Bay Water Utility]
  • Greendale: None [WISN]
  • Hales Corners: None [WISN]
  • Kenosha: 7,326 service lines [MJS]
  • Little Chute: Cannot find data**
  • Madison: None***
  • Manitowoc: 43% or 6,579 service lines [GBPG, MJS, Manitowoc Public Utilities]
  • Milwaukee: 70,000 service lines (~44%)
  • Neenah: ~3,900 service lines [Neenah Water Utility]
  • Racine: 10,437 service lines [MJS, Racine Water Utility]
  • Sheboygan: 38% of service lines [GBPG]
  • Shorewood: 90% to 95% or 3,150 to 3,325 service lines (WISN reports the lower, MJS the higher)
  • South Milwaukee: 32% of service lines [WISN]
  • Wausau: 37% of service lines [GBPG]
  • Wauwatosa: 65% of service lines (~9,750 properties) [WISN]
  • West Allis: 38% or >8,000 service lines [WISN, MJS]
  • Wisconsin Rapids: 1% of service lines [GBPG]

Call your local water provider and city/county officials to ask if you are affected.  Then ask what the plan is to replace lead service lines.

*Eau Claire Public Works has a tool to determine if your property has a lead service line.
**In Little Chute, you can determine if your home has a lead service line by contacting the Village of Little Chute Water Department at (920) 788-7522 or email
**Madison started a concerted effort to replace all lead pipes in 2001.  It took over a decade to replace the pipes to all 8,000+ properties.  The city maintains a program for properties owners who discover they have lead pipes.
****Neenah, since 1994, has replaced ~2,080 lead service lines to the curb stop.  It’s possible the service line from the curb stop to the property may still be lead.

Dr. No to Science

Though the state legislature appropriated money to the DNR to assist with this problem for 2017-18, Wisconsin’s highest elected officials have not always treated lead as the public health concern it is.  Secretary Tommy Thompson, the Governor of Wisconsin from 1987-2001 and former U.S. Health and Human Services Secretary in the George W. Bush Administration has a complicated role in Wisconsin’s legacy of lead.  Secretary Thompson was criticized by the Union of Concerned Scientists for rejecting three scientists to the CDC Advisory Committee on Childhood Lead Poisoning Prevention in 2002.  The rejections, and subsequent appointment of alternative members, were done prior to a committee meeting where lead standards were likely to be toughened.  The UCS cited in their scathing report that this was the first time “an HHS secretary had ever rejected nominations by the committee or CDC staff.”

In their place, according to a Congressional report, Secretary Thompson appointed individuals with ties to the lead industry.  One appointee, Dr. William Banner, stated lead was only harmful at 7-10 times the CDC blood lead level at the time, a position that “either ignores or willfully misreads some four decades’ worth of accumulating data on lead exposure in children.” [UCS report]  In all, Secretary Thompson rejected one reappointment and two recommended appointments while appointing five other individuals, three of whom with industry ties.

Secretary Thompson was criticized for a politicization of science beyond just the lead advisory committee during his tenure at US HHS (2001-05).

Leaden Cultural Background 

When I have shared what I found with my landlord and neighbors I realized how normalized lead contamination was in the state.  My landlord and neighbors were already following the individual lead mitigation efforts I listed above.  My landlord stated every child growing up in Milwaukee was taught not to drink hot water and to bleed pipes until the water ran cold in the morning.  This is a great public health victory in terms of public awareness, and a troubling statement on our culture.

No one suggested to me as a new resident that caution should be taken with the water.  No one mentioned they bled their pipes or they installed their own filters.  The fact lead pipes are bringing water into homes is so well-known and normalized it has become part of the cultural background.  I don’t blame my neighbors; I look, sound, and act like I am from their culture.  

But lead is dangerous.  Those 70,000 properties with lead services lines?  Here they are on a city map:

Lead’s MKE Reach

Call to Action

The problem of lead is everywhere.  The legacy of lead is statewide.  The dangers has been known since ancient times.  But the solutions are also known.  I hope the plethora of sources out there on lead in Wisconsin are a sign of public concern.  I hope the good steps being taken by the DNR and municipalities are born of a conviction to eradicate the problem.  So what can you do?

  1. Find out if you have a lead service line and potentially get a water filter (If in MKE possibly for free).
  2. Take actions to mitigate risk of lead in your drinking water.
  3. Call your local water provider and city officials to ask if your water is affected.
  4. Ask your city/county officials what the plan is to replace lead service lines.
  5. Find out if you home has lead paint.
  6. Find out if your yard’s soil has lead contamination.
  7. Tell your family, friends, and neighbors.

Let’s fix this legacy.  Let’s make lead a legacy of Wisconsin’s past.
