$10 in benefits for every $1 invested – Minnesota estimates benefits of lead service line replacement

Last week, the Minnesota Department of Health (MDH) released a report estimating that investing $4 billion in virtually eliminating lead in drinking water over 20 years would provide societal benefits of more than $8 billion. The state agency only counted the societal benefits from avoiding the loss of IQ points due to children’s exposure to lead.

Replacing lead service lines (LSLs) – the lead pipes that connect a building’s plumbing to the water main under the street – yielded the greatest benefit with an investment of $0.228 to $0.365 billion yielding $2.118 to $4.235 billion in benefits. Replacing lead fixtures and solder had a lower, but still significant, return on the investment.

Based on this analysis, MDH recommended as high priority that the state conduct an inventory of LSLs and that LSLs be removed “at a measured pace” of 20 years. It also recommended undertaking as a medium priority an awareness campaign focused on the danger of lead in drinking water to formula-fed infants younger than nine months old and as a low priority a general public information campaign to prompt homeowners and renters to take action if they have an LSL.

The agency, which includes both the state’s drinking water protection program and its lead poisoning prevention program, prepared the report in response to a provision in a state appropriations law passed in 2017. The report is important because it is the first state assessment we know of, and it reports an impressive return on the investment of more than $10 for every $1 invested in LSL replacement. For these reasons, we took a close look at the analysis and the underlying assumptions.

California Water Board makes misleading claim that only four water systems have lead lines

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: December 7, 2018

Tom Neltner, J.D., Chemicals Policy Director

[Update 12/14/18: The California Water Boards added a webpage providing more background for customers on the inventory requirement, including the clarification that “user service line” does not include the service line on private property. This clarification was also added to the Status Map webpage.]

The California Water Board posted the results of its statewide inventory of lead service lines (LSLs) in community water systems (CWSs) yesterday. They also became the first in the nation to post the results in an interactive online map. We are pleased to see the state take this important step, but are disappointed that the press release it sent out to announce the map’s launch undermines its efforts with misleading and confusing statements.

The central problem is that the press release fails to be clear that the inventory does not cover the portion of the service line between the meter and the home or building.  As a result, a CWS that removed all of the lead pipes between the main under the street and the meter but left them on private property was listed as having no LSLs. A customer would justifiably – but mistakenly – assume that LSLs were not an issue in their community.

Mapping state-level lead service line information: Indiana as a model

By Lindsay McCormick / Published: October 8, 2018

Lindsay McCormick, is a Project Manager. Tom Neltner, J.D., is the Chemicals Policy Director.

Developing inventories to document and share what water utilities know – and do not know – about lead service lines (LSLs) with the public is a difficult, but critical, step in creating an effective LSL replacement program.

States can play an important role in collecting estimates of the number of known and potential LSLs for each utility and shaping how that information is communicated to the public. 14 states have surveyed utilities operating community water systems in their state to acquire such information.

States have made this information publicly available through different methods. Some have posted individual utility reports, while others have provided a report summarizing the findings. In analyzing the approaches, we found that no state currently makes the results available in a format that allows the public to easily see the information from multiple utilities.

But in today’s world, people typically expect data to be presented in a visually friendly and digestible format. So as a model, we decided to create a state-level map of LSL information.

Of the 14 states, we found that Indiana has one of the most robust surveys, asking detailed questions about portions of the service line containing lead, information sources checked, and service line ownership on public versus private property.  Further, it has a good response rate for a voluntary survey. While only 57% of systems responded, these systems account for 92% of the service lines in the state – as most non-respondents were primarily smaller community water systems.

EDF acquired a spreadsheet from the Indiana Department of Environmental Management and combined this information with data from EPA’s State Drinking Water Information System (SDWIS) to develop a map of LSLs in Indiana as a model.

FDA-approved PFAS and drinking water – Q&A on textile mills and environmental permits

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: June 21, 2018

Tom Neltner, J.D., Chemicals Policy Director, and Maricel Maffini, Ph.D., Independent Consultant

In May 2018, we released a blog highlighting paper mills as a potentially significant source of drinking water contamination from 14 Food and Drug Administration (FDA)-approved poly- and per-fluorinated alkyl substances (PFAS) used to greaseproof paper. We showed that wastewater discharge could result in PFAS concentrations in rivers in excess of the Environmental Protection Agency (EPA)’s 70 parts per trillion (ppt) health advisory level for drinking water contamination for PFOA and PFOS, the most studied of the PFASs. We identified 269 paper mills with discharge permits that warrant investigation. Readers of the blog have asked some important questions highlighted below. As with most issues involving PFAS, there are many gaps in what we know. Based on the information provided in response to EDF’s Freedom of Information Act (FOIA) request to FDA, we hope to fill in some of the gaps and highlight key information needed to better understand the risks of PFASs.  

Question 1: Could textile mills also be a source of PFASs in drinking water?

The answer is “probably.” The FDA-approved PFASs can be used in coating paper that contacts food to repel oil, grease, and water. The same or similar FDA-approved PFASs may be used for non-food uses such as coating textiles to resist stains and repel water.

The processes used to coat paper and textiles differ in some aspects that could affect a mill’s environmental releases. For paper, the PFASs are typically added to the wet wood fibers to be made into paper. In contrast, we understand that PFASs are applied to textiles after the water is removed. Therefore, we would suspect that the amount of PFASs, whether as polymers or impurities, released with the wastewater of a textile mill would be lower compared to that of a typical paper mill. However, there is very little data available to assess the potential environmental release of PFASs from textile mills. Unlike with FDA approvals, there is no environmental review of a chemical’s use in non-food consumer products.[1] So, it would be worthwhile to investigate textile mills for use of PFASs in addition to looking at paper mills.

Using an EPA database[2], we identified 66 textile mills (PDF and EXCEL) in the US, two thirds of which are located in North and South Carolina. Based on wastewater flow, the two largest mills are both operated by Milliken. Its largest facility is in Greenville, South Carolina with a water discharge of 72 million gallons per day (MGD). The second largest is in Bacon, Georgia with a water discharge of 15 MGD. DuPont’s Old Hickory facility, near Nashville, Tennessee, had the third greatest flow at 10 MGD. We do not know whether any of the facilities use and discharge FDA-approved PFASs.

Pennsylvania empowers municipalities to replace lead service lines

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: December 11, 2017

[pullquote]Pennsylvania was already one of the 11 states taking proactive efforts to support LSL replacement since 2015. HB-674 expands that effort.  Check our website for what states and communities are doing. [/pullquote]Tom Neltner, J.D., is Chemicals Policy Director

In October 2017, the Pennsylvania General Assembly passed and Governor Wolf signed HB-674 which implements the State’s 2017-18 budget. Section 1719-E of the law includes a provision empowering municipal authorities to replace or remediate private water and sewer laterals if the municipality determines the work “will benefit the public health.” Read More »

Wisconsin on the verge of taking an important step to replacing its lead pipes

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: December 6, 2017

Tom Neltner, J.D., is Chemicals Policy Director

In 2012, Madison, Wisconsin became the first city in the country to fully eliminate its lead service lines (LSLs), the lead pipes that connect the drinking water main under the street to interior plumbing. The project to replace its 8,000 known LSLs began in 2000. The City’s effort is a model of persistence and common sense as it overcame many barriers including challenges with the Public Service Commission of Wisconsin (PSC).

The PSC blocked the use of rates paid by customers to fund replacement of lead pipes on private property. The PSC, whose mission is to ensure adequate and reasonably priced water service, was concerned that customers without LSLs would be subsidizing improvements to the property of those with LSLs. Unlike most state commissions which are responsible for utilities operated by private companies, PSC approves rates for municipal and private utilities. Eventually, Madison used a different source of funding for its $15.5 million LSL replacement program.

Currently, the Wisconsin State Legislature is on the cusp of passing legislation to remove this barrier faced by Madison and empower communities to better protect residents from lead in drinking water. SB-48, introduced by Senator Cowles (R-Green Bay) and co-sponsored by Representative Thiesfeld (R-Fond du Lac), has passed both chambers. When the legislature returns to session in January 2018, they will need to resolve a difference between the two versions regarding the maximum amount of financial assistance allowed to homeowners. To hear from both authors on the legislation, check out the webinar from the National Conference of State Legislatures regarding financing options for replacing LSLs.

With passage of the legislation, Wisconsin would be the fourth state to pass essential legislation empowering communities to replace LSLs, using rates paid by consumers, joining Indiana, and Pennsylvania. They are among 12 states that have adopted administrative or legislative policies to support community LSL replacement.  These states have an estimated 3.3 million of the nation’s 6.1 million LSLs.
