Michigan utilities report much lower percentages of service lines of lead or unknown material than Wisconsin or Illinois

Note to readers: As we all grapple with the grave global health challenge from COVID-19, we want to acknowledge the essential service that the public health professionals at water utilities provide in delivering safe water not only for drinking but for washing our hands and our surroundings. In the meantime, we are continuing to work towards improved health and environmental protections – including reducing lead in drinking water. We’ll plan to keep sharing developments regarding lead in drinking water that may be useful to you. In the meantime, please stay safe and healthy.

Lead service line (LSL) inventories provide useful insights into the location and number of LSLs in states and the funding needed to fully replace these lines. In previous blogs, we examined mandatory reporting by utilities of service line material in Illinois and Wisconsin.[1] Here, we examined a March 2020 preliminary report by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) summarizing data submitted by 1,029 utilities. Unlike the annual reporting in Illinois and Wisconsin, Michigan required utilities to submit a preliminary inventory by January 1, 2020 and requires a complete inventory before 2025. While the preliminary report allows lines to be designated as unknown, the material must be determined by 2025. This is a two-step process, rather than the annual report approach that California has taken.

Michigan reports less than 100,000 LSLs and 276,000 lines of unknown material that may be lead

The state’s preliminary report is based on 1,029 utilities[2] (74% of the state’s 1,386 total) with 2.40 million service lines (90% of the 2.66 million total).[3] This reporting rate is lower than what Illinois experienced at a similar stage in the first year of mandatory reporting.

For the 1,029 utilities that reported, utilities reported 99,000 (4% of total) lead, 21,000 (0.9%) galvanized steel,[4] 177,000 (7%) of unknown material but likely to be lead, and 276,000 (12%) as unknown with no information. If all of the four categories are actually lead (which is unlikely), there would be 573,000 (23%) LSLs in Michigan.

Illinois poised to strictly limit partial lead service line replacement: How does it compare to Michigan and proposed EPA rules?

Illinois is poised to be the second state in the country to strictly limit the practice of partially replacing lead service lines (LSL). Partially – rather than fully – replacing these lines that connect the drinking water main under the street to homes can significantly increase lead levels in drinking water for months and does not reliably reduce lead levels over time. Last week, the Illinois Department of Public Health (IDPH) released amendments to the Illinois Plumbing Code that include significant restrictions on partial LSL replacements. If the state’s legislative oversight committee for rulemaking does not object, the agency can finalize the rule.

If adopted, the changes would set the stage for all LSLs and galvanized service lines in the state to eventually be fully replaced. The changes are significant because the Illinois has an estimated 679,000 LSLs, by far the most in the country, as well as 60,000 galvanized service lines, and an additional 1.07 million service lines of unknown material that may be lead.

Michigan, with its estimated 460,000 LSLs, took a similar action in June 2018 when it strengthened its version of Environmental Protection Agency’s (EPA) Lead and Copper Rule (LCR). However, Michigan’s rule applies only to public water systems (PWS). In contrast, Illinois’s planned revisions apply to anyone who alters a service line including both PWSs and licensed plumbers.

In October, EPA proposed revisions to the LCR. However, unlike Michigan and Illinois, EPA’s proposed rule would continue to allow PWSs to conduct partial replacements where the property owner is unwilling or unable to pay the cost for the portion not owned by the PWS.

Where are Illinois’ lead pipes? Chicago Water has nearly 60%, and small systems don’t know.

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: September 25, 2019

Tom Neltner, J.D., Chemicals Policy Director and Lindsay McCormick, Program Manager.

Chicago is the epicenter for lead service lines (LSLs) in the United States. In a report submitted to Illinois Environmental Protection Agency (IEPA) in April, Chicago Water reported having 392,614 LSLs – 75% of the total service lines in its water system that serves 2.7 million people living in the city and the city’s 125 suburbs. The number of LSLs is over three times higher than any other city. For additional context, this number represents 58% of the known LSLs in Illinois and 6% of the estimated 6.1 million LSLs in the country.

Chicago Water also reported an additional 120,760 service lines as unknown material that may be lead. Only 7,299 (2%) of its total service lines are made of something other than lead.

These numbers are based on the second year of mandatory reporting that IEPA makes publicly available. Earlier this year, we summarized the first year of reporting. In the second year of reporting, IEPA improved the program by allowing CWSs to separately report lines of unknown material where the utility was confident they were not LSLs – most likely because the lines were installed after the date the CWS stopped allowing use of lead. So the remaining lines of “unknown material” were more likely to be lead. In addition, all community water systems (CWSs) in the state reported in the second year.[1] Given these improvements, we looked more closely at the data.

EDF analysis: Lead service lines in Illinois communities

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: April 4, 2019

Tom Neltner, J.D., Chemicals Policy Director

Building statewide, comprehensive inventories of lead service lines (LSLs) in community water systems (CWSs) is a critical part of any effort to eliminate lead pipes. With a solid inventory, states can conduct a credible needs assessment and engage the public in supporting community efforts to replace LSLs.

In January 2017, the Illinois legislature passed a law designed to reduce children’s exposure to lead in drinking water. It included a requirement that CWSs submit annual reports to Illinois Environmental Protection Agency (IEPA) regarding a “water distribution system material inventory” by April of each year. EDF sees Illinois’s approach to developing an inventory as a model to be considered by other states because it:

  • Requires all CWS to report (unlike Indiana which had a well-designed one-time voluntary survey but only a 57% response);
  • Covers the entire service line (unlike California which ignored the portion of the service line on private property); and
  • Requires annual updates to track progress, especially in reducing the number of service lines with unknown materials (unlike Michigan which requires updates only every five-years).

In August 2018, IEPA released a summary of the first year submissions and has updated it several times. IEPA indicated that 95% of CWSs submitted reports and provided totals of each type of piping material reported with 414,895 LSLs and 1,504,748 of unknown material. At the time, the agency did not provide information on what each CWS reported.

Making totals public is important but does little to engage the public in understanding what the information means for their community. But earlier this week, IEPA published an online tool, which allows residents to search for their water system and download the data for individual reports of the types of materials currently reported by their water system.  EDF also received the information pursuant to a Freedom of Information request. Click here to see the data for all the CWSs in a spreadsheet. We also used an EPA database to identify the 84 CWSs that did not comply with the law.

Mandatory lead service line inventories – Illinois and Michigan as strong models

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: July 30, 2018

Tom Neltner, J.D., Chemicals Policy Director and Lindsay McCormick, Project Manager

This blog is part of a series focused on how states are handling the essential task of developing inventories of lead service lines (LSLs) and making them public. The first blog identified 14 states that were taking on the issue: four with mandatory programs and ten with voluntary.  In this blog, we explore the four mandatory programs and highlight Illinois and Michigan as strong models for other states to consider.  Updated 11/3/18 to reflect updated estimates from Illinois.

Four states – California, Illinois, Michigan and Ohio – require utilities that operate community water systems (CWSs) to identify and report to the state in some form their number of lead service lines (LSLs). Illinois and Michigan both have strong approaches that could serve as models for other states and EPA to require nationally. California’s approach is seriously flawed because it ignores part of the service lines and can be misleading. Ohio requires utilities to either report they have zero LSLs or provide maps where the LSLs are likely to be found, with no requirement to provide an estimated number. We explore all of these approaches below.
