New study: Using interactive online tools to publicize lead service line locations and promote replacement

EDF study evaluates interactive online tools in three Ohio cities that help users know which addresses have a lead service line.

In 2016, EPA called upon states to work with drinking water utilities to make publicly available the location of lead service lines (LSLs, the lead pipes that connect the main under the street to buildings) via maps or other mechanisms. Ohio led the way with legislation requiring more than 1,800 utilities to submit static PDF maps that showed where LSLs were likely to be present and then posting the maps online. Three cities in the state took the effort a step further to communicate the information to their customers by posting online tools. In 2016, Cincinnati posted an interactive map of LSLs modeled after one posted by Washington, DC earlier that year. The next year, Columbus posted an interactive map and Cleveland posted a search engine enabling anyone to check the service line material at an address.

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

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.

Cincinnati and Ohio show leadership in identifying and disclosing lead service lines

Tom Neltner, J.D.is Chemicals Policy Director

Transparency is an essential aspect of any successful program to reduce lead in drinking water. Knowing if you have a lead service line (LSL)—the pipe that connects the main under the street to the building—can help you decide whether to use a filter or replace the line. If you are looking for a home to rent or buy, the presence of a LSL can be a factor in your choice. Transparency can also help reassure consumers that their utility is aware of the problem and committed to protecting their health. The challenge for many water suppliers is that they often don’t have perfect information about the presence of LSLs. But incomplete information is not a reason for failing to disclose what is known, what is uncertain, and what is unknown.

In a February 29, 2016 letter to the states, U.S. Environmental Protection Agency (US EPA) asked states to increase transparency by posting on either the state’s website or have it posted on local utilities’ websites:

“the materials inventory that systems were required to complete under the [Lead and Copper Rule] including the locations of lead service lines [LSLs], together with any more updated inventory or map of lead service lines and lead plumbing in the system.”

In response to this letter and systemic issues brought to light about lead in drinking water in the village of Sebring, Ohio and Flint, Michigan, the State of Ohio enacted pragmatic legislation crafted by Governor John Kasich’s administration and the Ohio Environmental Protection Agency (Ohio EPA). Among its supporters was the Ohio Environmental Council. One provision in the law requires community water systems to

“identify and map areas of their system that are known or are likely to contain lead service lines and identify characteristics of buildings served by the system that may contain lead piping, solder, or fixtures . . .”

Utilities must submit the information to Ohio EPA as well as the departments of Health and of Job and Family Services by March 9, 2017 and update this information every five years.
