New study: Homebuyers and renters take action when told they may have a lead service line

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

The Cornell/EDF study confirmed that potential buyers or renters report being much more willing to take action to replace LSLs when told they have one regardless of disclosure style. However, water testing information that shows levels below EPA’s lead action level may underestimate risk and undermine action on LSLs.

Today, EDF and collaborators at Cornell published a new study that provides insight into how disclosure policies can impact potential home-buyer and renter behavior. This effort builds on a report EDF published in 2017 grading state housing disclosure policies according to their ability to help homebuyers make informed decisions about lead service lines (LSLs) before they sign a sales contract. LSLs are pipes that connect homes to the water mains under the street and are a major source of lead in drinking water. Four states — Connecticut, Delaware, New York, and Pennsylvania — and Washington, DC scored an A-. Twenty-one states scored a D or F. The remaining 25 states scored a B or C.

Our analysis was based on a presumption that if potential homeowners are told that a home has an LSL, many would negotiate with the property owner for its removal, whether by having the seller replace it or building the cost into the mortgage to fund the buyer’s replacement. This was a reasonable presumption that underlies why sellers are required to disclose property defects and environmental hazards in many states.

However, we were interested in testing that presumption and exploring how potential homebuyers and renters might respond differently based on how the information is disclosed by a property owner or home inspector. Our objective was to evaluate disclosure styles to assess if the different styles influenced respondents’ perceived risk of the LSL in a home and willingness to act. To conduct the survey, we partnered with Jeff Niederdeppe and Hang Lu of Cornell University’s Department of Communications who recruited 2,205 participants online and gave them one of three scenarios to consider and advised them it would cost $1,000-5,000 to replace the LSL. See Figure 1 below.

Trump Administration’s lead action plan is a missed opportunity to protect kids from lead

Tom Neltner, J.D.Chemicals Policy Director

Yesterday, the President’s Task Force on Environmental Health Risks and Safety Risks to Children released its long-delayed Federal Action Plan to Reduce Childhood Lead Exposures and Associated Health Impacts (Lead Action Plan). A year ago the Task Force described this document as a federal lead strategy that would identify clear goals and objectives to “serve as a ‘roadmap’ for federal agencies on actions to take to reduce childhood lead exposure.” It requested feedback on the approach and received over 700 public comments.

The Trump Administration’s Lead Action Plan falls far short of what was promised. To understand what the Plan is and what it is not, we compared it to two earlier documents from the Task Force: 1) A federal lead strategy released in February 2000 by the Clinton Administration focused on reducing exposure to lead-based paint; and 2) An inventory of key federal programs released in November 2016 by the Obama Administration summarizing the activities of the 17 federal agencies and departments with responsibilities to protect children from lead.

Lead from a new “lead-free” brass faucet? More common than you’d hope

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

Until NSF/ANSI 61 standard is updated to reduce or eliminate lead leaching, users must extensively clean and flush new brass fixtures before use and make a short flush standard practice for older fixtures.

During this past year, we undertook a pilot project to tackle the problem of lead in drinking water at child care facilities. As part of the effort, we collected 250 mL samples (about 8 ounces of water) from every drinking water fixture, as recommended in the Environmental Protection Agency’s (EPA) 3Ts guidance for schools and child care facilities. We replaced 26 faucets that exceeded our action level with new brass faucets that were labeled “lead-free” and complied with NSF/ANSI 61 standard for drinking water system components.[1] To our surprise, when we sampled the faucets a few days after replacement, the lead levels were higher– between 9 and 10 ppb – on three of the new faucets.

The increase left us scratching our heads. Federal law allows a drinking water fixture to be labeled “lead-free” if the amount of lead in wetted surfaces[2] averages less than 0.25% (down from the 8% limit between 1986 and 2014). However, it isn’t clear how much this amount might contribute to levels of lead in water. To explore this issue, we contacted the supplier who said its product was certified under NSF/ANSI 61 and, therefore, not likely the source. The supplier suggested the source could be from existing upstream valves or from disturbing the plumbing. We could not rule these other possibilities out.

A study by Virginia Tech’s Jeff Parks on three models of new NSF/ANSI 61 certified brass faucets found similar results and concluded that even newly manufactured “lead-free” faucets may not meet the 1 ppb limit that the American Academy of Pediatrics (AAP) recommends for schools.

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

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.

American Water demonstrates strong leadership on lead service line replacement

Tom Neltner, J.D.is Chemicals Policy Director

In a landmark decision on July 25, 2018, the Indiana Utility Regulatory Commission (IURC) approved American Water’s plan to fully replace the lead service lines (LSLs) in the communities served by its Indiana subsidiary over the next 10 to 24 years. This represents the replacement of about 50,000 LSLs across 27 community water systems (CWSs). As we highlighted in our blog on the company’s January 2018 proposal, the plan provides a framework that enables the cost of fully replacing LSLs, whether owned by the utility or by customers, to be shared by its 300,000 customers. As far as we know, this is the first comprehensive, voluntary LSL replacement program developed by an investor-owned utility in the country.

In its plan, American Water cited both long-term health and economic benefits that would be realized from avoiding partial replacements when rehabilitating water mains and laterals. The plan showed that having a single contractor handle the entire line reduces the overall cost by 25 to 30%. It also avoids the likely increased risk of consumer’s exposure to lead when only part of the lead pipe is replaced.

IURC’s approval found the plan “to be reasonable and in the public interest.” Even though the customer will continue to own the service line, American Water will be allowed to add the cost to remove and replace the customer-owned portion to the value of the utility’s property. The increase would be considered an infrastructure improvement cost once the new service line is placed into service.

Lead service line inventories – Indiana as a good model of a voluntary survey

Tom Neltner, Lindsay McCormick, and Audrey McIntosh

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: 4 with mandatory programs and 10 with voluntary. The second blog described programs in four states that mandate an inventory. In this blog, we highlight Indiana’s 2016 voluntary survey of utilities operating community water systems (CWSs) as a model because it ask utilities to: 1) identify who owns the line and provide the legal basis for that claim; and 2) rate its confidence in its estimates on a 1 to 10 scale. 

We found no other state survey asked about LSL ownership even though it is a central question in determining who is expected to pay for replacement. The Environmental Protection Agency’s (EPA) National Drinking Water Advisory Council (NDWAC) recommended[1] in 2015 that the agency require utilities to provide states this information as part of a revised Lead and Copper Rule (LCR). Unfortunately, 43% of the 781 CWS did not respond to Indiana’s survey, revealing a serious limitation of voluntary surveys.

In January 2016, a month before EPA encouraged states to develop an inventory of LSLs and make it available to the public, the Indiana Department of Environmental Management (IDEM) sent a two-page survey to utilities that operate CWSs in the state asking about drinking water service lines. The agency posted scanned PDF copies of the individual responses online but has not yet released a summary.[2]
