EPA's Final Lead and Copper Rule Improvements
Technical Fact Sheet: Summary of Benefits and Costs

October 2024

The final Lead and Copper Rule Improvements (LCRI) strengthen nationwide requirements to protect children
and adults from lead in drinking water. These advancements are commonsense, achievable, and built on actions
taken by states and cities. There is no known safe level of lead in drinking water. Exposure to drinking water
contaminated with lead can cause serious human health impacts including neurodevelopmental problems in
children and heart disease in adults.

The final LCRI benefits significantly outweigh the costs. EPA estimates the benefits are up to 13 times greater
than the costs. Investments in removing lead pipes will create good-paying local union jobs. The Lead and
Copper Rule Improvements will improve public health and help protect millions of people across the country
from exposure to lead in drinking water.

Potential Impact

Benefits

$13.5-$25.1
Billion per
year

Annually, the rule will protect up to 900,000
infants from low birthweight, prevent up to 2,600
children from experiencing Attention Deficit
Hyperactivity Disorder (ADHD), reduce up to 1,500
cases of premature death from heart disease, and
prevent up to 200,000 IQ points lost in children.

The LCRI will help protect millions of
people across the country from exposure
to lead in drinking water.

Non-

quantified*

Decreased risk of heart-related diseases.
Preventing other developmental effects and
negative impacts to vital systems in the body
including to renal, reproductive, immune, and
nervous systems.

The rule will also increase public awareness of the
harmful effects of lead and potential sources of
lead at their home. Additional benefits from
lower exposure to lead in drinking water in homes
in systems with higher levels of lead and reduced
corrosion of pipes within homes.

Costs

$1.47-$1.95
Billion per
year

Estimated costs include replacing lead service
lines, water system monitoring, communicating
with customers, and - if necessary - installing
treatment technologies, among other actions. See
Table 3 for cost breakdown.

EPA estimates 67,000 water systems will
be regulated under this rule. Of these
systems, approximately 26,000 water
systems will be required to replace lead
and/or galvanized requiring replacement
(GRR) service lines and between 7,000-
10,000 water systems may have to take
additional actions (e.g., corrosion control
treatment) as a result of the new action
level.

States, Tribes, and territories with

Non-

quantified*

Cost of installing or increasing treatment and
some lead service line replacement (LSLR)-related
costs, such as the disruption of normal traffic
patterns in communities implementing LSLR
programs.

primacy will have increased oversight
and administrative costs.

*Non-quantified benefits and costs are those for which EPA could not assign a specific dollar amount as part of its national level
quantified analysis, but it does not mean their benefits or costs are less important than those with numerical values.

What are the benefits of the rule?

The final LCRI is expected to result in significant health benefits since exposure to both lead and copper in
drinking water are associated with adverse health effects. The estimated annual benefits of the rule are up to 13
times greater than its estimated annual costs. EPA estimates LCRI benefits will be up to $25 billion per year.
EPA's benefits assessment focuses on the estimated impact of reductions in lead exposure on IQ values and
cases of Attention-Deficit Hyperactivity Disorder (ADHD) in children, reduced low birth weights in children of
women of childbearing age, and cases of cardiovascular disease (CVD) premature mortality in adults.

Table 2. Quantified Health Benefits of the Final LCRI

Final LCRI Benefit

Annual Quantified Benefits Once Fully Implemented

Annual ADHD Benefits

$162.7-$419.6 million

Annual Adult CVD Premature Mortality Benefits

$7.70-$17.04 billion

Annual IQ Benefits

$5.62-$7.68 billion

Annual Low-Birth Weight Benefits

$3.9 - $4.4 million

Note: This table shows the quantified health benefits of the final rule. EPA expects there are significant additional non-

quantified health benefits that are not included but would result in a much greater number of avoided illnesses or deaths
once the rule is fully implemented.

What will implementation of this rule cost?

The annual benefits of the Lead and Copper Rule Improvements are estimated up to 13 times greater than the
costs. EPA estimates the incremental costs for public water systems and primacy agencies to implement this
regulation are between $1.47 billion (low estimate) and $1.95 billion (high estimate) per year. These costs
include regulated water systems completing service line replacement, improved lead and copper tap sampling,
new or improved corrosion control treatment, making lead filters available where required, and public
education. The estimated costs also include the cost of rule implementation to systems, States, Tribes, and
primacy agencies, as well as wastewater treatment costs.

Wastewater Treatment Costs

$0.0 to $0.3 million

Note: This table shows the quantified costs of the final rule. EPA expects there are additional non-quantified costs that are
not included that may result in other increased and decreased costs once the rule is fully implemented.

Why does EPA present costs and benefits on an annual basis?

Presenting estimated annual costs and benefits is useful because it allows considerations of costs and benefits
over different timeframes. For instance, more costs may occur in the first years of rule implementation, as water

systems invest capital to replace lead service lines, while benefits of avoided deaths and illnesses are anticipated
to increase over time since exposure to lead in the populations will be reduced after the rule is implemented.
For the LCRI, EPA has estimated the benefits and cost over a 35-year period of analysis.

Is funding available to support implementation of the rule?

There are a number of ways for systems to receive support for LSLR and lead-related activities. Through the
Bipartisan Infrastructure Law (BIL) and funding programs like the Drinking Water State Revolving Fund (DWSRF)
and WIFIA, there has never been more federal funding available to remove lead pipes.

The BIL appropriated $26 billion in supplemental DWSRF funding for lead-related activities and reemphasized
the importance of LSLR under the DWSRF program by including $15 billion specifically appropriated for lead
service line replacement projects and associated activities. Water systems are encouraged to contact their
State's DWSRF program to learn about project eligibilities, requirements, and how to apply for assistance
through the DWSRF.

The Water Infrastructure Improvements for the Nation (WIIN) Act established three drinking water grant
programs that are available to support activities to reduce lead exposures in drinking water, including the
Reducing Lead in Drinking Water grant program, the Voluntary School and Child Care Lead Testing and
Reduction grant program, and the Small, Underserved, and Disadvantaged Communities grant program.

Another option for LCRI funding is the Water Infrastructure Finance and Innovation Act (WIFIA) program, a
federal loan program at EPA that provides low-cost, flexible funding to communities for water infrastructure
projects, including projects to address lead and copper. WIFIA funding is available year-round, so communities
can request financing on their schedule.

These programs are part of the Justice40 Initiative, which set the goal that 40 percent of the overall benefits of
certain Federal climate, clean energy, water and wastewater infrastructure, and other covered investments flow
to disadvantaged communities that are marginalized by underinvestment and overburdened by pollution. EPA
has compiled information on federal and non-federal funding sources available to assist States and water
systems with replacement efforts, available online here: https://www.epa.gov/ground-water-and-drinking-
water/funding-lead-service-line-replacement.

Background

The Safe Drinking Water Act requires EPA to conduct a Health Risk Reduction and Cost Analysis to assess the
quantifiable and nonquantifiable benefits of the final LCRI and the quantifiable and nonquantifiable costs that
are likely to occur solely as a result of compliance with the rule, as well as assess other factors that may impact
this overall analysis. The benefits and costs presented throughout this fact sheet are incremental costs; that is,
the additional costs and benefits that public water systems, households, and States will incur in response to the
final LCRI, above those they would have under the 2021 LCRR if the LCRI was not enacted.
