PUBLIC-INTEREST INFRASTRUCTURE INTELLIGENCE

The water under your street is invisible finally visible.

An open map of the pipes, wells, lead service lines, and PFAS contamination that move, and threaten, drinking water across the United States. Stitched from federal, state, and municipal public records. Scored for failure risk by a published model. Not a dashboard. Not a sales tool. A civic instrument.

WHAT YOU CAN FIND

Hidden water risk, made legible to the people it's actually happening to.

Not built for utilities; they have their own systems. Built for everyone downstream of one: residents, journalists, local officials, public-health researchers, lawyers, organizers.

Lead service lines

The pipe between the main and your faucet.

Federal LCRR forced every utility to publish what's there. We pull every state inventory and plot it at the address level.

52,000+ records mapped · VT, MA, RI
PFAS contamination

Where forever chemicals showed up, and where testing points next.

State remediation sites, federal UCMR5 PWS samples, Do-Not-Eat advisory zones, and pathway diagrams from regulator records.

22,000+ sites + samples · six states
Pipe failure risk

Which mains rank highest on failure-risk factors.

Risk score with a transparent decomposition: every pipe shows what's driving its score: age, material, soil, breaks, climate.

14,283 high+critical segments
Wells & groundwater

State registries no one combined before.

NHDES, MassDEP, VT ANR, Maine MGS, and USGS NWIS, merged into one queryable layer. Every state, every well type.

460,000+ wells in registry
Service-area boundaries

Which utility actually serves your address.

From EPA SDWIS plus state-published boundaries with population, connections, and source type per system.

4,200+ water-system + wellhead boundaries
Hydrants & valves

The distribution skeleton, traced.

Real BWSC hydrants in Boston. RIGIS E‑911 statewide. VCGI E‑911 statewide. Plus 20+ city utility GIS systems.

78,000+ real hydrant points

Public records in. Honest map out.

Every layer carries its source. Modeled is labeled modeled. Coverage percentages are real. When the data is sparse, the map says so; we don't paper over gaps with synthetic dots.

The risk model is published in full, and its methods and sources are documented. The cities we drop because the data wasn't real: we publish that too. If it's not in the public record, it doesn't ship.

Six New England states are the prototype. The same pipeline expands to the other 44.
