What Newark Residents Should Know
Newark experienced a significant lead contamination crisis between 2017 and 2021, when elevated lead levels were found in many homes. The crisis was caused by ineffective corrosion control treatment, which allowed lead to leach from service lines and plumbing fixtures into the drinking water.
In response, Newark launched one of the nation's most ambitious lead service line replacement programs, replacing nearly all of the city's lead service lines in just over three years—a project that was initially estimated to take 10 years. This unprecedented program has been completed as of early 2023, with approximately 24,000 lead service lines replaced.
While the lead service line replacement program has been highly successful, residents should remain vigilant, as lead can still be present in older homes with lead plumbing fixtures, faucets, or solder. Newark has also updated its water treatment protocols to include improved corrosion control measures.
Lead Service Line Replacement Program
Newark's program is considered a model for the nation in addressing lead contamination.
Program Completion Status
All 24,000 lead service lines have been replaced throughout Newark as of early 2023, making it one of the fastest and most comprehensive lead pipe replacement programs in the United States.
Crisis Identified
Newark's water sampling revealed elevated lead levels above the EPA action level of 15 ppb, with some samples showing lead levels over 50 ppb.
Initial Response
Newark distributed water filters to affected residents and began planning a lead service line replacement program.
Program Launch
The city launched its Lead Service Line Replacement Program with $120 million in bonds from the Essex County Improvement Authority, allowing free replacements for homeowners.
Accelerated Replacement
Despite the COVID-19 pandemic, Newark continued replacing lead service lines at a rate of approximately 90 per day.
Approaching Completion
By the end of 2021, over 22,000 lead service lines had been replaced, with lead levels showing significant decreases.
Program Completion
Newark announced the successful completion of its lead service line replacement program, with all 24,000 lead service lines replaced—a project initially estimated to take 10 years completed in just over 3 years.
Key Contaminants of Concern
These contaminants have been monitored in Newark's water supply.
Lead
ImprovingSource: Lead service lines (now replaced) and older plumbing fixtures
Health Effects: Developmental delays in children, kidney problems, cardiovascular effects, reproductive issues
Current Levels: 7.1 ppb (90th percentile), down from over 45 ppb during peak of the crisis
EPA Limit: Action level 15 ppb, but no safe level exists
Haloacetic Acids (HAA5)
Near LimitSource: Byproduct of water disinfection process
Health Effects: Increased risk of cancer with long-term exposure; reproductive and developmental effects
Current Levels: Varies by quarter, occasionally approaching the limit
EPA Limit: 60 ppb
Total Trihalomethanes (TTHMs)
Near LimitSource: Byproduct of water disinfection process
Health Effects: Liver, kidney, or central nervous system problems; increased risk of cancer
Current Levels: Varies by quarter, occasionally approaching the limit
EPA Limit: 80 ppb
Copper
Below LimitsSource: Corrosion of household plumbing systems
Health Effects: Gastrointestinal distress, liver or kidney damage with long-term exposure
Current Levels: 0.07 ppm (90th percentile)
EPA Limit: Action level 1.3 ppm

Lead Levels by Ward
| Ward | Pre-Program Lead Levels (2018) | Current Lead Levels (2024) | Percent Reduction | Service Lines Replaced |
|---|---|---|---|---|
| East Ward | 48.3 ppb | 6.2 ppb | 87% | 4,325 |
| West Ward | 52.6 ppb | 7.5 ppb | 86% | 5,280 |
| South Ward | 41.8 ppb | 6.8 ppb | 84% | 4,840 |
| North Ward | 36.5 ppb | 5.9 ppb | 84% | 5,120 |
| Central Ward | 45.2 ppb | 8.4 ppb | 81% | 4,435 |

Recommended Action Steps
Even with Newark's successful lead service line replacement program, residents should take these steps to ensure their water is safe.
Flush Your Pipes Before Use
If water hasn't been used for 6 hours or more, run cold water for 5 minutes to flush any standing water that may contain lead from plumbing fixtures.
Verify Your Service Line Replacement
If you're unsure whether your lead service line has been replaced, contact the Newark Lead Service Line Replacement Program to verify your address in their database.
Use Cold Water for Consumption
Always use cold water for drinking, cooking, and preparing baby formula. Hot water is more likely to contain lead and other contaminants.
Clean Faucet Aerators Regularly
Remove and clean faucet aerators (screens at the end of faucets) monthly to remove any trapped lead particles, especially in older homes.
Consider Lead Testing for Your Home
If you have concerns or live in an older home, consider having your water tested for lead, especially if you have young children or are pregnant.
Replace Old Fixtures
If your home was built before 2014, consider replacing old faucets and plumbing fixtures that may contain lead. Look for "lead-free" certified fixtures.
