Mercer County, New Jersey
Pennington Boro knows where its lead lines are. The work is replacing them by 2031.
Its filing records 153 connections to replace and no connections of unrecorded material, so the question here is scheduling and cost rather than searching. Towns still carrying unknowns have to pay to find theirs before they can plan at all.
What the law requires
P.L.2021 c.183 obliges every public community water system in New Jersey to inventory every service connection, notify the public about what it finds, and replace all lead service lines by 2031. Progress is reported to the state each year and posted publicly.
Pennington Boro is its own public community water system. L.2021 c.183 inventory, notification and 2031 replacement duties are the town's own.
Why a known count is a scheduling problem rather than a search
Pennington Boro's filing puts 153 connections on the replacement list and leaves nothing unidentified. That removes the most expensive uncertainty in this programme, which is paying to find out what you have.
What is left is a scheduling and disruption problem: which streets, in what order, alongside which paving and utility work, and how the required resident notification is handled for each one.
Ordering still decides the cost, but the thing being ordered is replacement work rather than investigation.
Where Pennington Boro stands
Pennington Boro operates its own water system (Pennington WD), so the c.183 replacement duty is the town's directly in its 2024 filing.
Pennington WD (PWID NJ1108001) reported 0 known lead service lines, 153 galvanised lines requiring replacement, 0 connections whose material was never recorded, 830 confirmed not lead, as of its 2024 submission. With no unknowns and no lead reported, this system's inventory is complete on its own account, which is a materially different position from a town still resolving unknowns.

What the state publishes, and what it does not
Published, free
NJDEP publishes how many connections each system reported as lead, galvanised, unknown and confirmed non-lead. Those are the numbers above. Systems over 3,300 people also have to put an address lookup on their own website.
Not published anywhere
Which of those unknowns to open first. The state publishes counts, not an order, and an address lookup answers one property at a time. Nobody publishes a ranked list, which is the thing a crew schedule is actually built from.
That gap is what we work in. We hold construction year for every parcel in New Jersey and the plumbing permit history behind it, so we can put a system's unknowns in order and show the evidence for each one. It is a ranking, not a diagnosis: it says where to look first, and it never claims a particular property has lead.
The arithmetic, with the count already settled
153 connections already identified for replacement脳your cost to replace one=the programme, with no search to pay for first
The count is settled, so the variable is replacement cost per connection and the order the work is done in, not how much finding it will cost.
Funding, and what gates it
We have not confirmed this town's hazard mitigation plan yet.
Federal hazard-mitigation funding requires a current FEMA-approved plan. We match plans automatically by county and jurisdiction name, and this one did not resolve. It does not mean the plan is missing.
That is a gap in our record, not a finding about Pennington Boro.
Lead replacement is financed through the Drinking Water State Revolving Fund, with principal forgiveness available. The borrower is the water system, which is the town itself only where the town runs its own water. Which of those Pennington Boro is decides who applies.

- We have not baked Pennington Boro's impervious and runoff layers yet, so there is no number here. That is different from the number being zero.
- We have not baked Pennington Boro's storm-drainage layer yet, so there is no number here. That is different from the number being zero.
How we know
- FEMA National Flood Hazard Layer flood zones and base flood elevation
- NJDEP MS4 outfalls the mapped storm-drainage network
- OpenFEMA HMA subapplications what happened to grant applications like yours
- FEMA Hazard Mitigation Plan Statuses the grant gate
- NJDEP service line inventory what each water system reported to the state, by year
