§ I · The surface
Before signing a purchase agreement on a Davidson County home, every careful buyer eventually arrives at the same question: what would the public record tell me about this specific address that the listing won't? The answer is more than most people realize. Underground fuel tanks within a half mile. Dry cleaner solvent sites two blocks downwind. Federal Superfund records on adjacent parcels. PM2.5 elevation from the interstate at the rear of the lot. Active rail traffic two hundred feet from the bedroom wall. Transmission corridors crossing the parcel boundary. Closed landfills that still off-gas methane. Radon-zone designations that affect every house in the county.
Each of these records is public. Each lives in a separate database. Each is searchable by address or coordinates if you know where to look. A careful buyer with a free afternoon can assemble most of the picture themselves. Most start. Most stop within an hour, somewhere between the second and third unfamiliar agency website.
This page is about what the buyer's question actually requires. Not the casual scan most people do — the real version, the one that produces a defensible record before a real-estate decision. The rest of the chapter walks through what's in the data, why the do-it-yourself route is harder than it looks, and what we charge to do it for you.
§ II · The hidden layer
The thirteen categories Parcelscope reads against your address fall into four practical clusters. The federal and state databases below are public, free, and individually searchable. The Field Guide chapters elsewhere on this site explain each category in depth.
Contamination and cleanup records
TDEC · EPA SEMS · DCERP · UST Finder
Underground storage tanks and confirmed releases, dry cleaner solvent sites, Superfund and federal cleanup records. These are the records that document specific contamination events at specific parcels — present, historical, and archived.
Proximity exposures
OpenStreetMap · FRA · TVA · NES · EPA LMOP
Major roads and interstates, active rail corridors, high-voltage transmission lines, landfills and waste sites. These are the chronic, low-grade exposures that accumulate over years of living in a particular location.
Air quality and emissions
EPA TRI · ECHO · Metro APC · AirNow
Toxic Release Inventory facilities, regional PM2.5 monitoring, ozone monitoring. The point sources and the ambient background that determine what's actually in the air over your house.
Property characteristics
EPA Map of Radon Zones · EPA EnviroAtlas · FAA BNA · curated venues
Radon geology zone, tree canopy coverage, golf course proximity, aircraft noise contours, event venue density. The slower-moving variables that shape the lived experience of a specific neighborhood and a specific parcel.
Every one of these records can be retrieved by a determined homebuyer. None of them are paywalled, hidden, or proprietary. The retrieval is the easy half of the work. What follows is the harder half.
§ III · What the records show
Most homebuyers who try to assemble their own environmental records picture do not finish. The reasons follow a predictable pattern. Four of them, in roughly the order they tend to bite:
The interfaces fight you
TDEC's UST search wants a facility name. EPA's UST Finder wants latitude and longitude. The LMOP registry returns facility-level records that need to be cross-referenced against a parcel map. The DCERP data viewer is on a separate state subdomain that just changed names. Each database has its own conventions, its own filter logic, and its own help documentation. The intellectual content is straightforward; the friction is real.
The findings are easy to misread
A registered dry cleaner is not a contaminated parcel. A closed LUST file is not an empty site. An NFRAP Superfund record is not a remediated-to-background site. A Group 2B IARC classification is not a confirmed health risk. A 40% radon testing rate is not a 40% population frequency. Every category has at least one pattern of misreading that produces either false confidence or unwarranted alarm. Reading the records without the framing the Field Guide chapters provide is how most homebuyers reach the wrong conclusion about their own address.
Distance, direction, and wind compound
A finding at 0.4 miles in one direction is not the same as a finding at 0.4 miles in another direction. A facility upwind on Nashville's prevailing southwest-to-northeast pattern affects your house differently than the same facility downwind. Translating each finding's coordinates into a parcel-relative distance and bearing, then weighing that bearing against ten years of NOAA wind observations from BNA, is where the work actually compounds. The retrieval gets you to the data. The translation is the synthesis.
The closing clock doesn't wait
Most buyers are running a thirty-day, forty-five-day, or sixty-day closing timeline. Three to four hours of unfamiliar database work, repeated across thirteen categories, fits into the timeline in theory and never in practice. The do-it-yourself route works best when there's no transaction pending. The need for the records works exactly the opposite way.
The Field Guide hub publishes a ten-step pre-close checklist that lays out the DIY method openly. The chapters of the Field Guide explain each hazard category in depth. The information is here. The work is real.
§ IV · The bottom line
A Parcelscope report skips the three-to-four hours. We run all thirteen public records categories against your specific address, contextualize each finding against the address's prevailing wind exposure, score each category on a consistent scale, and render the entire picture as a single PDF you can read in fifteen minutes and act on the same day. The records are public; the synthesis is the product. Forty-nine dollars. Delivered within twenty-four hours of order.
For most Davidson County homebuyers, this is the right answer. The records exist for a reason; reading them against your specific address before closing is the kind of decision that distinguishes informed buyers from the much larger group who close without checking. The cost of the report is a rounding error against any closing transaction. The cost of not knowing what's on the public record is exactly the kind of risk a $49 product is designed to eliminate.
The DIY path remains here for anyone who prefers it. The Field Guide hub at getparcelscope.com/field-guide publishes the ten-step pre-close checklist openly. Each hazard chapter walks through the science and the records for its own category. The agencies that maintain these databases publish their own search interfaces, all linked from the Field Guide. None of it is hidden. The choice is yours.
