Address-level environmental intelligence

Every address has a history. Most of it isn't in the listing.

GroundReport connects public federal and state databases to find hidden environmental risks at any US address — then turns them into a sourced report with action steps.

How it works

Environmental risk, made legible

We translate fragmented public databases into one environmental report for a single address — nine risk categories, every finding sourced, with an action plan, and a cost estimate where one applies, for each finding in the paid report.

01

Enter an address

Any US residential address. We geocode it instantly and match it to the right water utility, census tract, and regulatory jurisdictions.

02

We query public databases

EPA drinking water violations, FEMA flood zones, USGS radon maps, Superfund proximity, county assessor build year, and more — in seconds.

03

Deterministic risk engine

Hard-coded rules convert raw data into risk levels. No AI sets your risk levels — every flag traces to a specific data point and source.

04

Fully sourced report

Every finding cites its exact source — EPA, ATSDR, HUD, CDC — with a link to the source. You see the evidence, not just the conclusion.

Coverage

Nine categories. One address.

Click any category below to see what we look up and where the data comes from.

Health context

Not just numbers. Sourced context.

Where a finding has a published health profile, the report shows what EPA, CDC, ATSDR or IARC say about the substance, with a link to each source. The report states what the records show; it does not predict health outcomes.

🧬Body System Mapping

Each hazard profile lists the body systems that EPA, CDC, ATSDR or IARC associate with the substance, with a link to that agency's page.

ℹ️Not a Diagnosis

Agency information describes a substance in general. It is not a measurement of exposure at your address, and it is not medical advice.

🔬Agency Classifications

Where IARC has published a classification for a contaminant (Group 1, 2A, 2B), the report shows that classification as the agency's own, with a link to the classifying agency.

💚Actions Tied to Findings

Each recommended action in the paid report is linked to the finding it addresses, with a cost range and a cited source. The report makes no claim about health outcomes.

📋47 Hazard Profiles

From lead and PFAS to radon and wildfire smoke — a profile for each hazard we track, summarized from EPA, CDC, ATSDR and IARC with a link to each source.

📖Sourced Health Context

Health information is summarized from EPA, CDC, ATSDR and IARC, each with a link to the source.

Action Plan

Every finding comes with a prioritized action plan and a cost estimate where one applies, matched to what we found at your address.

What a report covers

One address, nine categories.

Flood maps, water-quality records and EPA site databases are published separately by different agencies. Ground Report looks up the records that apply to one address across nine categories and shows the source of each finding, in one report.
