Land Well & Septic Report

The answer

62 water-supply wells are recorded within 1 mile; the middle half of those with a recorded depth (62) were drilled 146–236 ft deep, median 188 ft. 0 dry holes are recorded within 5 miles. The nearest USGS monitoring well measured in the last 10 years, 2.58 mi away, was 32.23 ft below the land surface on 2026-08-12 (approved, well depth 120.1 ft). The main soil here, Pella (85% of the mapped soil unit), is rated “Very limited” for conventional septic absorption fields (ponding, depth to saturated zone, slow water movement).

Drilled depth is how deep a neighbouring well was drilled, not the depth at which water was found. Neighbouring wells don't guarantee what a new well on this land will find.

FEMA's flood map places this point in Zone X (area of minimal flood hazard), outside FEMA's Special Flood Hazard Area.

Location

Illinois parcel boundaries aren't loaded, so wells and soils are measured from this point.

Neighbouring water wells

Water-supply wells in the ISGS database (private, farm, livestock, irrigation, commercial, business, industrial, subdivision, municipal and public supply wells). A depth or pumping rate of 0 or blank is shown as not recorded. Ranges are printed only where at least 5 values exist.

“Middle half” is the 25th to 75th percentile of the recorded depths, taken by linear interpolation between the two nearest values (the method PostgreSQL calls percentile_cont), then rounded to the nearest whole foot, with a value exactly halfway rounded to the nearer even foot.

The ISGS service selected 1 further record whose distance, re-measured here from your coordinates, is just over 5 miles, so it is not counted in the 5-mile row above. That is why the record count in the sources table is larger.

Soil and septic suitability

Soil map unit: Pella silty clay loam, cool, 0 to 2 percent slopes. USDA rating for conventional septic tank absorption fields, by soil component:

USDA soil surveys are mapped at field scale, not for a single lot. Only an on-site soil evaluation or percolation test settles what system the land can take.

Questions for drillers and the county

What this report doesn't cover

• Not a hydrogeological survey, soil evaluation or percolation test. CivicDelta doesn't advise whether to buy.
• Drilled depth is not the water level: ISGS doesn't record the level found. Measured water levels come from USGS monitoring wells nearby, not from this land.
• Well locations in the ISGS database can be approximate, and many wells were never recorded.
• The flood zone is FEMA's mapped zone at one point; the map panel's effective date and pending map revisions aren't included.
• Absence of a record (a dry hole, a well) is not evidence that none exists.
• The coordinates were confirmed to fall in Illinois, and in a census block containing land, against the U.S. Census Bureau's TIGER boundaries. That is a boundary check on one point, not a check of the parcel line, of who owns the land, or of whether anything may be built on it.
