For Cliffside Park overall, lead monitoring produces 0.0110 mg/L - beneath the point where EPA requires utilities to formally respond.

Lead Risk Overview

The average 90th percentile lead level in Cliffside Park, New Jersey is 0.0110 mg/L. The EPA action level is 0.015 mg/L (15 parts per billion). This is within the EPA action level, though the EPA states there is no safe level of lead exposure.

Housing Age and Lead Risk

Lead plumbing solder was banned in 1986. Homes built before this date may have lead in:

• Solder joints connecting copper pipes
• Lead service lines connecting the water main to the home
• Brass fixtures and faucets containing up to 8% lead (pre-2014)

In Cliffside Park:

With over half of housing stock built before 1986, Cliffside Park has elevated risk of lead in residential plumbing. This is particularly concerning for homes built before 1978 (when lead paint was also banned) and before 1950 (when lead pipes were most common).

Health Effects of Lead Exposure

Lead exposure is a serious public health concern with no safe level identified by the CDC:

Children (under 6):

• Developmental delays and learning difficulties
• Reduced IQ and attention span
• Behavioral problems
• Slowed growth

Adults:

• Kidney damage
• High blood pressure
• Reproductive issues
• Nerve disorders

Pregnant women are especially at risk - lead crosses the placenta and affects fetal development.

Three-Source Lead Data Confirmation

Lead risk is best understood by combining multiple data sources:

Cross-referencing multiple sources provides a more complete picture of lead risk than any single dataset.

Lead Service Line Replacement (LSLR)

The EPA's revised Lead and Copper Rule (LCRR) requires all water systems to create a service line inventory by October 2024 and replace lead service lines within 10 years. Cliffside Park's water system is subject to these requirements.

Federal funding for New Jersey:

This funding is available through the Drinking Water State Revolving Fund (DWSRF) for lead service line inventory and replacement projects in New Jersey.

To check if your home has a lead service line:

1. Check your water utility's service line inventory (required to be publicly available)
2. Inspect where the pipe enters your home - lead pipes are dull gray and can be scratched with a key
3. Contact your water utility for a free service line inspection

Lead Risk by Housing Decade

The age of a home is one of the strongest predictors of lead risk in drinking water:

With a median build year of 1978, the typical home in Cliffside Park falls in the moderate-high risk category for lead in plumbing. 74% of homes were built before the 1986 lead solder ban.

How to Test for Lead in Cliffside Park

DIY Test Kits ($20–$50)

• Available at hardware stores and online
• Collect a "first-draw" sample (water sitting in pipes 6+ hours)
• Send to an EPA-certified lab for analysis
• Results typically in 1–2 weeks

Professional Lab Testing ($150–$400)

• Comprehensive panel: lead, copper, bacteria, nitrates, and more
• Certified technician collects samples
• Best for homes built before 1986 or after a plumbing change

Free Testing Options

• Many water utilities offer free lead testing - call your provider
• Some states offer free testing for homes with children under 6
• Check your annual Consumer Confidence Report (CCR) for system-wide results

What to Expect

• Below 0.005 mg/L (5 ppb): Low concern
• 0.005–0.015 mg/L (5–15 ppb): Consider filtration, especially with children
• Above 0.015 mg/L (15 ppb): Exceeds EPA action level - take immediate action
• Above 0.040 mg/L (40 ppb): Use bottled water while addressing the source

Lead and Copper Rule Sampling History

Historical 90th percentile lead levels (ppb) from water systems serving Cliffside Park:

When the quarterly source does not publish sample counts, multi-system lead values are unweighted means of the available system 90th-percentile reports. They are not weighted by sample count.

Lead levels have decreased from 14 ppb (1992) to 11 ppb (2025), suggesting improving conditions.

The EPA action level is 15 ppb. Any year exceeding this threshold triggers mandatory corrective action under the Lead and Copper Rule.

How to Reduce Lead Exposure

1. Flush your pipes - run cold water for 2+ minutes before drinking, especially in the morning
2. Use cold water for cooking and baby formula (hot water dissolves more lead)
3. Install a certified filter - look for NSF/ANSI Standard 53 certification for lead removal
4. Get your water tested - EPA-certified kits cost $20–$50
5. Replace lead service lines - check with your utility about replacement programs
