USDA SSURGO Soil Suitability, Hydric & Septic Screener

Give it a list of coordinates. Get back, for each one, the USDA SSURGO soil map unit, every percent-weighted soil component in it, the prime-farmland class with its condition, the hydric rating, drainage class, slope, hydrologic soil group, and NRCS limitation ratings for septic fields, dwellings with and without basements, small commercial buildings, local roads, shallow excavations and ground-based solar arrays -- each with the reasons behind the rating.

Straight from USDA NRCS Soil Data Access. No API key, no scraping, no third-party re-hosting.

The thing most soil lookups get wrong

A SSURGO map unit is almost never one soil. It is a percent-weighted mixture.

Take a real one -- mukey 411286, Hayden loam, 2 to 6 percent slopes, Story County, Iowa:

Component	Share	Hydric?	Drainage
Hayden	85%	No	Well drained
Le Sueur	10%	No	Somewhat poorly drained
Glencoe	5%	Yes	Very poorly drained

A tool that reports only the dominant component tells you "not hydric" and moves on. That is a confident wrong answer on exactly the question a wetland delineator, a septic designer or a Phase I consultant is asking: 5% of that map unit is hydric soil, and hydric soil is one of the three wetland indicators under the Corps 1987 manual.

This actor reports both: the dominant-component value and an any-component flag, the hydric share as a percentage, the components by name, and the most-limiting rating found anywhere in the map unit alongside the dominant one. That distinction is in the field names, not buried in a note.

It also publishes what SSURGO does not describe. Map unit 116094 documents a single component at 85% -- the other 15% of that map unit is undocumented, and an unmapped inclusion in it can still be hydric. You get that residue in components_percent_undocumented rather than a silent assumption that it is 100% Norfolk sand.

Who it is for

• Septic and onsite-wastewater designers -- perc feasibility, seasonal high water table, and the specific NRCS reasons a site is limited, before anyone drives out to dig a test pit.
• Land developers and homebuilders -- shrink-swell and wetness constraints on foundations and roads, plus the prime-farmland class you need for FPPA (7 CFR 658) when there is any federal nexus.
• Geotechnical engineers -- frost action, corrosivity to steel and concrete, hydrologic soil group, slope range, and taxonomic family, as a desktop pass before the boring plan.
• Solar and data-center siting teams -- NRCS ships two purpose-built solar interpretations (ballast anchor and soil-based anchor); this actor reports both, including the steel-corrosion and frost-action reasons that drive them.
• Phase I ESA and wetland-delineation prep -- hydric soils and drainage as a screening layer, with an honest "not evaluated" instead of a false clear.
• AI agents -- one coordinate in, a flat typed row out.

Use as an MCP tool

Every published Apify actor is callable by an AI agent through mcp.apify.com. The input is a plain list of coordinates and the output is a flat, fully described, typed row per site -- so an agent can chain this into a siting or due-diligence workflow without any glue code.

What "null" means here

null means not checked. false means checked, and the answer is negative. They are never collapsed.

Every row carries a per-source status -- mapunit_status, component_status, interpretation_status, legend_status -- plus sources_ok_count and data_complete. If the NRCS interpretation table does not answer, every septic and foundation rating on that row is null and the status reads unavailable. It will never read "Not limited" off a table that was never read. If every site fails at the source, the run FAILS and bills nothing rather than publishing a page of confident blanks.

A coordinate USDA has not soil-mapped -- open water, or an unsurveyed area -- returns lookup_status: "out_of_coverage" with every soil field null. That is an explicit "not evaluated", not a clear.

Columns that are legitimately null

Six declared columns are null on most rows because SSURGO only populates them in specific places. Each has a verified live input that does populate it, so you can tell "not applicable here" from "broken":

Column	A coordinate that populates it
lookup_error	any out-of-coverage, rejected or partial site, e.g. 44.0, -87.0 (Lake Michigan)
iowa_corn_suitability_rating	42.110415, -93.560137 (Iowa; NRCS publishes CSR only there)
dominant_soil_slip_potential	61.566941, -150.422585 (Matanuska-Susitna, Alaska)
hydric_rating_vocabulary_unknown	only populates if SSURGO changes its hydric domain
drainage_vocabulary_unknown	only populates if SSURGO changes its drainage domain
drift_gate_warnings	only populates when the drift gate passes with a warning

On a healthy, fully-covered run those last four are all null, and that is good news rather than a dead column. Measured on the prefill: 4 of 149 columns null, all four of them for that reason.

Two columns were deliberately not shipped: SSURGO's mustatus and muhelcl are null for every row in the entire national map-unit table (measured live), so declaring them would have put two permanently empty columns on this page.

Live drift gate

Before a single billable row exists, every run verifies the upstream against a fixed reference scope and fails loudly if any check regresses:

1. Positive canary -- a known coordinate must still resolve to map unit 411286. This matters because USDA answers a malformed geometry with HTTP 200 and an empty body, byte-identical to a genuine unmapped point.
2. Negative control -- a point 1,500 km out in the Atlantic must return nothing. A spatial filter that quietly matches everything would otherwise pass every other check.
3. Multi-component structure -- the canary map unit must still return three components summing to ~100% with exactly one minority hydric component. If that collapses, this actor's entire differentiator is silently gone.
4. Interpretation availability -- all eight NRCS rule names must still exist. A rename upstream would otherwise render as a permanently absent limitation.
5. Closed vocabularies -- hydric rating, drainage class and limitation class are checked against a fixed survey area. An unknown value there fails the run. (An unknown value on your map unit is surfaced in a *_vocabulary_unknown column and excluded from derived flags instead -- one odd map unit can never take the actor down.)
6. Freshness and scale -- the newest survey-area refresh and the survey-area count must be in band.

Every measured value is logged on every run.

Pricing

$8 per 1,000 results. One screened site = one result. Out-of-coverage and rejected-input rows are billed as results because they are real answers about that site; a run where every site failed at the source, or every asset was invalid, fails and bills nothing.

FAQ

Is this a wetland delineation? No. Hydric soil is one of three wetland indicators; a delineation needs hydrology and vegetation too, and field verification. This is a desktop screen that tells you where to look.

Is this a septic permit? No. It is the NRCS soil interpretation, which is what county health departments and designers screen with before a percolation test. It is not a substitute for a site evaluation.

Why does almost nothing come back "Not limited" for septic? Because that is what SSURGO actually says. In a real county (Story County, Iowa) the live distribution is 174 map-unit components "Very limited", 46 "Somewhat limited", 9 "Not rated", and zero "Not limited". "Somewhat limited" is the practical best case across much of the country. The actor reports NRCS verbatim rather than rescaling it into something more flattering.

Does it cover Alaska, Hawaii and Puerto Rico? Wherever NRCS has published a soil survey, yes -- Anchorage resolves fine. Unsurveyed areas return out_of_coverage.

How current is the data? SSURGO is refreshed annually per survey area. Every row carries survey_data_refreshed and survey_data_age_days for its own survey area, and ssurgo_newest_survey_refresh for the database as a whole.

Can I get the raw component records? Yes -- components_json carries every component with all 36 fetched SSURGO attributes, and interpretations_json adds the NRCS fuzzy values and any sub-rules NRCS could not evaluate.

Output fields

All 149 fields, every one nullable. null = not checked; false = checked and negative.

Field	Type	Description
asset_label	string	The label you supplied for this site, echoed back so rows can be joined to your own records.
asset_index	integer	Zero-based position of this site in the assets array you supplied. Preserved even for rejected sites so you can match every row back to its input.
latitude	number	WGS84 latitude of the point that was screened.
longitude	number	WGS84 longitude of the point that was screened.
checked_at	string	UTC timestamp of this run.
data_source	string	The authority this row came from.
source_url	string	The USDA Soil Data Access endpoint queried.
lookup_status	string	ok = a soil map unit was found and read. out_of_coverage = USDA publishes no soil map unit here (NOT a finding of "no limitations"). invalid_input = the coordinate was rejected before any request. source_error = USDA could not be read for this site, so every soil field is null rather than negative.
lookup_error	string	Why this row is not a complete answer: the out-of-coverage explanation, the input rejection reason, the upstream error, or a PARTIAL note naming which SSURGO tables did not answer. Null on a clean, complete row.
mapunit_status	string	Whether the SSURGO mapunit table answered for this site: ok, unavailable, or not_applicable.
component_status	string	Whether the SSURGO component table answered. When this is not ok, every component, hydric, drainage and slope field on this row is null - not negative.
interpretation_status	string	Whether the SSURGO cointerp table answered. When this is not ok, every septic, foundation, road and solar rating on this row is null - never "Not limited".
legend_status	string	Whether the SSURGO legend and survey-area catalog answered for this site.
sources_ok_count	integer	How many of the four SSURGO tables answered for this site.
sources_total_count	integer	How many SSURGO tables this row depends on. Always 4.
data_complete	boolean	True only when all four SSURGO tables answered. False means at least one block of fields on this row is null because it was never checked.
mukey	string	SSURGO map unit key (mukey) for the polygon containing this coordinate. The join key for any further SSURGO work.
musym	string	Map unit symbol as printed on the published soil survey sheet for this survey area.
national_musym	string	National map unit symbol, stable across survey areas.
map_unit_name	string	Full SSURGO map unit name, e.g. "Hayden loam, 2 to 6 percent slopes".
map_unit_kind	string	Consociation, Complex, Association or Undifferentiated group. A Complex or Association means the map unit is deliberately a mixture of soils, so the minority components matter more.
map_unit_acres	number	Total acreage of this map unit across the survey area (not the acreage of your parcel).
map_unit_investigation_intensity	string	NRCS order of the soil survey that produced this map unit. Order 2 is the standard county-level intensity; a coarser order means broader map units and more inclusion risk.
map_unit_interp_focus	string	The land use this map unit was interpreted for, where NRCS populates it.
iowa_corn_suitability_rating	number	Iowa CSR productivity index. Populated only in Iowa; null everywhere else because NRCS does not publish it, not because productivity is zero.
survey_area_symbol	string	SSURGO soil survey area code, e.g. IA169.
survey_area_name	string	Name of the soil survey area, usually a county.
survey_area_type	string	Whether the survey area is an MLRA or a non-MLRA soil survey area.
survey_map_scale	integer	Denominator of the original mapping scale. 15840 means 1:15,840 - roughly 4 inches to the mile. A coarser scale means bigger minimum-size delineations and more unmapped inclusions.
survey_data_version	string	NRCS version number of this survey area, incremented at each refresh.
survey_data_refreshed	string	Date this survey area was last refreshed by NRCS (ISO). Null when NRCS did not publish one, never today.
survey_data_age_days	integer	Days between this survey area last being refreshed and this run. NRCS refreshes SSURGO annually.
farmland_class	string	The SSURGO farmlndcl value exactly as NRCS publishes it. Most values are CONDITIONAL, e.g. "Prime farmland if drained".
farmland_category	string	Normalised category: prime, prime_if_conditional, statewide_importance, local_importance, unique_importance, or not_prime. Null when NRCS did not populate a class or published one this build does not recognise.
farmland_condition	string	The condition attached to a conditional class, e.g. "drained" or "irrigated and drained". This is what an FPPA reviewer needs and what a plain prime/not-prime flag destroys.
prime_farmland	boolean	True only for "All areas are prime farmland". A conditional class is FALSE here and true in prime_farmland_possible, because a wet field is not prime farmland until it is drained. Null when NRCS published no class.
prime_farmland_possible	boolean	True when the map unit is prime farmland either outright or once its stated condition is met. Use with farmland_condition for FPPA (7 CFR 658) screening.
farmland_class_recognized	boolean	False when SSURGO published a farmland class this build does not know how to interpret; the raw text is still in farmland_class and every derived flag is null rather than guessed.
component_count	integer	How many soil components SSURGO documents for this map unit. More than one means the dominant soil is not the whole story.
components_percent_sum	number	Sum of comppct_r across the documented components. SSURGO does NOT require this to reach 100.
components_percent_undocumented	number	The share of the map unit SSURGO does not describe at all (100 minus the documented sum). Measured up to 15% on real map units; an unmapped inclusion in that residue can still be hydric, so it is published rather than assumed away.
dominant_component_name	string	Name of the highest-percentage soil component in this map unit.
dominant_component_percent	number	Representative percentage of the map unit occupied by the dominant component.
dominant_component_kind	string	Series, Taxadjunct, Miscellaneous area, Family and so on. A "Miscellaneous area" such as Urban land or Water carries no drainage class or hydrologic group by design.
major_component_names	string	Semicolon-separated names of the components NRCS flags as major for this map unit.
dominant_hydric_rating	string	The raw SSURGO hydricrating of the dominant component: Yes, No or Unranked.
dominant_component_is_hydric	boolean	True/false for the dominant component only. NULL when its rating is Unranked or absent - Unranked means NRCS did not rate it, not that it is upland.
any_component_hydric	boolean	THE field a wetland delineator wants: true when ANY component of the map unit is hydric, including a 5% minority. Null when no component carries a rating. A dominant-component-only report answers "no" here and is wrong.
hydric_component_percent	number	Sum of comppct_r across every hydric component. 5 means 5% of this map unit is hydric soil.
hydric_component_names	string	Each hydric component with its share, e.g. "Glencoe (5%)".
hydric_component_count	integer	How many components are rated hydric. Null when nothing was rated.
hydric_unranked_component_count	integer	How many components carry no usable hydric rating. A high count means the hydric picture for this map unit is incomplete.
map_unit_hydric_class	string	all hydric, partially hydric, or not hydric, following the NRCS hydric-soils convention. Null when no component was rated.
hydric_rating_vocabulary_unknown	string	Any hydricrating value SSURGO returned that is outside the known Yes/No/Unranked vocabulary. Such a value is reported here and excluded from every derived flag rather than guessed. Null on normal data.
dominant_drainage_class	string	NRCS natural drainage class of the dominant component. Null on a Miscellaneous area such as Urban land or Water, which NRCS does not assign one.
wettest_drainage_class	string	The wettest natural drainage class found on ANY component of the map unit - the one that governs a septic or basement decision.
drainage_classes_present	string	Every distinct drainage class across the components, semicolon separated.
poorly_drained_component_percent	number	Share of the map unit whose drainage class is Somewhat poorly drained or wetter. Null when no component carries a drainage class.
drainage_vocabulary_unknown	string	Any drainage class SSURGO returned outside the known eight. Reported rather than scored. Null on normal data.
dominant_slope_percent_representative	number	Representative slope of the dominant component, in percent.
dominant_slope_percent_low	number	Low end of the slope range for the dominant component.
dominant_slope_percent_high	number	High end of the slope range for the dominant component.
slope_percent_min	number	Lowest representative slope across all components.
slope_percent_max_representative	number	Highest representative slope across all components.
slope_percent_max_high	number	Highest slope_h across all components - the steepest slope SSURGO allows anywhere in this map unit.
slope_percent_weighted_mean	number	Component-percentage-weighted mean of the representative slopes.
dominant_hydrologic_soil_group	string	NRCS hydrologic soil group (A/B/C/D, or a dual group such as C/D) of the dominant component - the runoff curve-number input for stormwater design. Null on a Miscellaneous area.
hydrologic_soil_groups_present	string	Every distinct hydrologic soil group across the components.
dominant_taxonomic_class	string	Full USDA soil taxonomy family of the dominant component.
dominant_frost_action	string	Potential frost action of the dominant component (Low/Moderate/High) - a pavement and shallow-foundation input.
dominant_corrosion_concrete	string	Risk of corrosion to uncoated concrete for the dominant component.
dominant_corrosion_steel	string	Risk of corrosion to uncoated steel for the dominant component - the driver behind solar soil-anchor limitations.
dominant_runoff_class	string	Surface runoff class of the dominant component, where NRCS populates it.
dominant_nonirrigated_capability_class	string	USDA non-irrigated land capability class (1-8) of the dominant component.

dominant_wind_erodibility_group	string	Wind erodibility group of the dominant component.
dominant_erosion_class	string	Erosion class of the dominant component, where NRCS populates it.
components_json	string	JSON array of every component with all 36 fetched SSURGO attributes - percentages, hydric rating, drainage, slope range, hydrologic group, taxonomy, corrosivity, capability class, wind erodibility, landform. Null when component detail is switched off or the component table did not answer.
interpretations_json	string	JSON object keyed by interpretation, carrying the NRCS rule name, the dominant fuzzy rating value, every limiting reason with its value, and any sub-rules NRCS could not evaluate. Null when detail is switched off or nothing was rated.
drift_gate_status	string	passed or passed_with_warnings. The run fails and bills nothing if the live drift gate does not pass, so this is never a failure value on an emitted row.
drift_gate_warnings	string	Any non-fatal drift observation from this run. Null when everything measured cleanly.
ssurgo_newest_survey_refresh	string	The most recent survey-area refresh date anywhere in SSURGO, measured live on this run - the freshness of the database as a whole.
ssurgo_survey_area_count	integer	How many soil survey areas SSURGO published at run time, measured live. A collapse here would mean a truncated catalog.
septic_tank_absorption_fields_rating_dominant	string	NRCS interpretation "ENG - Septic Tank Absorption Fields": NRCS limitation class for the DOMINANT component of the map unit: Not limited, Somewhat limited, Very limited, or Not rated. NULL when the interpretation table did not answer - never "Not limited".

This is what makes the rating actionable. Null when the rating carries no contributing reason.
septic_tank_absorption_fields_rating_worst	string	NRCS interpretation "ENG - Septic Tank Absorption Fields": The most limiting class found on ANY component, including a small minority one. Where this is worse than the dominant rating, part of the parcel is worse than the headline soil suggests. "Not rated" never counts as a severity.
septic_tank_absorption_fields_worst_component	string	NRCS interpretation "ENG - Septic Tank Absorption Fields": The soil component that produced the most limiting rating.
septic_tank_absorption_fields_percent_very_limited	number	NRCS interpretation "ENG - Septic Tank Absorption Fields": Share of the map unit whose components are rated Very limited for this use. Null when nothing was rated - never 0.
septic_tank_absorption_fields_percent_rated	number	NRCS interpretation "ENG - Septic Tank Absorption Fields": Share of the map unit NRCS actually rated for this use. A low value means the rating covers only part of the map unit.
septic_tank_absorption_fields_reasons_any	string	NRCS interpretation "ENG - Septic Tank Absorption Fields": Union of the limiting reasons across every component, highest fuzzy value first. Reasons that appear here but not in the dominant list come from minority components.

local_roads_and_streets_reasons_any	string	NRCS interpretation "ENG - Local Roads and Streets": Union of the limiting reasons across every component, highest fuzzy value first. Reasons that appear here but not in the dominant list come from minority components.
local_roads_and_streets_status	string	NRCS interpretation "ENG - Local Roads and Streets": ok = at least one component was rated. not_rated = NRCS returned the interpretation but rated nothing. no_data = SSURGO publishes no rows for this interpretation here. unavailable = the interpretation table did not answer, so every rating on this row is null rather than negative.
shallow_excavations_rating_dominant	string	NRCS interpretation "ENG - Shallow Excavations": NRCS limitation class for the DOMINANT component of the map unit: Not limited, Somewhat limited, Very limited, or Not rated. NULL when the interpretation table did not answer - never "Not limited".
shallow_excavations_reasons_dominant	string	NRCS interpretation "ENG - Shallow Excavations": The specific reasons behind the dominant component rating, each with its NRCS fuzzy value, e.g. "Depth to saturated zone (1.00); Slow water movement (1.00)". This is what makes the rating actionable. Null when the rating carries no contributing reason.
shallow_excavations_rating_worst	string	NRCS interpretation "ENG - Shallow Excavations": The most limiting class found on ANY component, including a small minority one. Where this is worse than the dominant rating, part of the parcel is worse than the headline soil suggests. "Not rated" never counts as a severity.
shallow_excavations_worst_component	string	NRCS interpretation "ENG - Shallow Excavations": The soil component that produced the most limiting rating.
shallow_excavations_percent_very_limited	number	NRCS interpretation "ENG - Shallow Excavations": Share of the map unit whose components are rated Very limited for this use. Null when nothing was rated - never 0.
shallow_excavations_percent_rated	number	NRCS interpretation "ENG - Shallow Excavations": Share of the map unit NRCS actually rated for this use. A low value means the rating covers only part of the map unit.
