Two profile pits
An excavator opens the ground so the soil is read in place, not sampled blind.

Soil & perc testing in Larimer County
Profile-pit soil testing across Larimer County — Northern Front Range / foothills at 5,000–8,500 ft — so your septic system is designed from what's actually in the ground, not a guess.
Two profile pitsLicensed evaluatorReg 43 soil designBedrock & groundwater depth
Every septic system in Larimer County is designed off the soil — and the soil here is anything but uniform.
Larimer County is plains edge climbing into foothills and mountain parks, with highly variable soils, and around Fort Collins, Loveland, Estes Park two lots a hundred feet apart can call for very different systems. That's why the design starts with opening the ground and reading it.
We dig two profile pits with an excavator and log the real profile — texture, structure, and depth to bedrock or groundwater — the evaluation Larimer County Department of Health & Environment and your engineer design from under Colorado's Regulation 43. A percolation rate alone won't cut it on this ground.
Before you commit to a lot, run the address through SepticIQ for an instant read off the USDA survey — then we confirm it on site with the pits.
What we do
Licensed evaluation
Texture and structure logged by a qualified evaluator, the way Reg 43 requires.
Bedrock & water depth
How much usable soil you have over refusal or groundwater — the make-or-break number in Northern Front Range / foothills.
Feeds your design
The log hands straight to your engineer to size the system and the soil treatment area.

Soil & Perc Testing in Larimer County — questions
How much does a soil / perc test cost in Larimer County?
Roughly $3,000–$5,000 — it takes an excavator on site to open two profile pits, read by a licensed evaluator. We quote it after a look at access and the lot.
Do you do a percolation test or a profile pit?
Profile pits. In Colorado the design comes from a soil profile evaluation — texture, structure, and depth to bedrock or water — not a perc rate alone. Larimer County Department of Health & Environment permits on that basis.
Can I get a soil estimate before I test?
Yes — SepticIQ reads the USDA soil survey for your Larimer County address instantly and sizes a likely system. The pit then confirms it.
