Thinking about listing a Keene property with a private well and septic system? Buyers love the space and independence that rural living offers, but they also worry about water safety, system capacity, and future costs. You can calm those fears fast by presenting clear, recent reports and records up front. In this guide, you’ll learn exactly which documents and tests matter most in Keene and greater Kern County, why buyers care, and how to gather everything before you hit the market. Let’s dive in.
Why well and septic prep matters
Kern County sits in the southern Central Valley, where groundwater can include elevated nitrate and naturally occurring minerals like arsenic or manganese. Private wells are not monitored the same way public systems are, so buyers look for recent, state‑certified lab results to feel confident about water quality and supply.
Buyers also want proof that both systems were legally installed and maintained. Permits, well logs, septic as‑builts, and service records show the systems match the property’s size and were properly cared for.
Finally, operational details affect near‑term costs and financing. Well yield, pump age, and septic capacity influence whether a buyer will need treatment, a pump replacement, or a septic repair after closing. Sharing documentation early reduces renegotiation and keeps your deal on track.
The documents buyers expect
Well permit and completion log
- What it shows: permit number, well depth, casing, static water level, driller, completion date, and production zone.
- Why buyers care: confirms a legal, competently built well and helps estimate expected yield.
Recent certified water test results
- Minimum for listings: total coliform, E. coli, nitrate/nitrite, plus basic chemistry like TDS or conductivity and pH.
- Recommended in the Central Valley: arsenic, manganese, fluoride, a metals panel, and VOCs or pesticides if near agriculture or industrial risk.
- Timing tip: buyers usually look for results within 30 to 90 days of listing for the microbiological and nitrate tests.
Pump and production data
- Include: pump type and age, service records, measured yield in gallons per minute, drawdown, and any recovery test.
- Why it matters: shows whether supply meets typical household demand and if a new pump may be needed soon.
Wellhead and setbacks details
- Provide: description or photo of the sanitary seal, distance to septic components, and distances to property boundaries.
- Why buyers care: basic sanitary protection and compliance with local standards.
Septic permit and as‑built map
- Include: tank size and location, leach field dimensions and type, distribution box, depths, and any perc/soil test results.
- Why it matters: confirms permitted capacity, location for future work, and alignment with the home’s bedroom count.
Septic maintenance and inspection records
- Provide: pump‑out receipts, inspection/evaluation reports, repair permits, alarm tests, and effluent filter cleanings.
- Why buyers care: shows regular maintenance and flags recurring issues early.
County permit search results
- Include: copies of recorded permits, approvals, repair permits, or variances.
- Why buyers care: transparency about legal status and any open items.
Treatment system documentation
- Include: manuals and certifications for filters, softeners, UV/chlorination, reverse osmosis, service contracts, and any disposal records for backwash or brine.
- Why buyers care: helps buyers plan for upkeep and replacement.
Soil/percolation test results
- When helpful: for older systems, suspected leach field issues, or planned additions/remodels.
- Why buyers care: supports capacity and replacement planning.
How to gather records in Kern County
Start with what you have
- Look for old folders from past sales or service calls.
- Collect invoices, permits, inspection reports, and any system sketches.
Which county offices to contact
- Kern County Environmental Health Services: septic permits, evaluations, and records.
- Kern County Planning & Development or Building & Development Services: well and pump permits, and related building records.
- Kern County Recorder/Assessor: recorded permits, easements, or older documents.
Have the parcel number and property address ready. Kern County files for older rural properties can be incomplete, so plan a little lead time.
State resources that help
- California Department of Water Resources: well completion report database and groundwater basin information.
- State Water Resources Control Board: private well guidance and lists of ELAP‑accredited laboratories.
- U.S. EPA: private well testing best practices and frequency guidance.
These resources are useful when county files are thin or you need lab options.
If records are missing
- Hire a licensed well driller or pump contractor to document current well data and run a production test.
- Hire a licensed septic contractor or Certified Onsite Wastewater Practitioner to produce a current septic map and inspection report.
What to test and when
Minimum tests for a strong listing
- Total coliform and E. coli
- Nitrate and nitrite
- TDS or conductivity and pH
These results answer the first buyer question: Is the water safe to drink without treatment?
Expanded panel for Keene properties
- Metals: arsenic, manganese, lead
- General chemistry: hardness in addition to TDS and pH
- VOCs and pesticides: consider if the property is near agricultural fields, irrigation ditches, fuel tanks, or oil and gas operations
How often to test
- Microbiological and nitrate: annually, and after flooding, well work, changes to treatment, or issues at nearby wells.
- Arsenic and metals: every 3 to 5 years, or sooner if local conditions suggest it.
- Full panel: before listing if there is no testing history.
Choosing a certified lab and handling samples
- Use a laboratory accredited by California’s Environmental Laboratory Accreditation Program.
- Follow the lab’s sampling instructions exactly. Use sterile bottles, deliver samples on time, and complete chain‑of‑custody forms. Improper sampling can invalidate results.
Typical costs to expect
- Basic coliform + nitrate panel: about $50 to $200.
- Expanded metals/VOC panel: about $150 to $500 or more.
- Septic inspection or pump‑out: about $300 to $800 or more, depending on tank size and access.
- Septic mapping or repair permit work: commonly $500 to $2,500 depending on complexity.
- Well production test or pump service call: about $300 to $1,000 or more based on scope.

Septic details buyers care about
What your as‑built should show
- Property boundary with north arrow and the home’s footprint
- Septic tank location and capacity, distribution box, and leach field layout
- Depths and trench footprints
- Distances to wells, property lines, and roads
- Access risers or cleanouts
Red flags and how to address them
- Missing permit or as‑built: schedule a licensed septic evaluation and mapping.
- Frequent pump‑outs or repairs: share the records and consider an inspection to confirm current function.
- Soggy areas or surfacing effluent: get a professional inspection and repair permit if needed before listing.
- Capacity concerns: verify the permitted bedroom count and share any perc results.
Local setbacks and approvals
Setbacks and design standards are enforced by Kern County Environmental Health. Confirm your system’s permitted capacity and note any variances. Include copies with your listing packet.
Well details buyers care about
Summarize your well clearly
Create a one‑page summary with:
- Well depth, pump setting depth, and static water level
- Most recent tested yield in gallons per minute and date
- Pump type, age, and last service date
- Treatment equipment on site
- Photo of the wellhead and sanitary seal
Watch for common red flags
- Low or inconsistent yield
- Recurring contaminants in test results
- Missing sanitary seal or evidence of contamination around the wellhead
- Very old pumps with no service history
If you see any of these, bring in a licensed well/pump contractor before you list.
Timeline and strategy before you list
- 60 to 90 days out: request county septic and well files; schedule a septic inspection and pump‑out if needed.
- 30 to 45 days out: order certified water testing from an accredited lab; schedule a licensed well and septic evaluation report.
- At listing: upload a clear one‑page summary, recent lab reports, the well completion log, pump and service records, the septic permit and as‑built, and maintenance receipts. Share these with buyer agents on request.
Providing this package upfront turns unknowns into knowns, which reduces post‑inspection price cuts and speeds up decisions.

FAQs
Are well water tests required to sell in Kern County?
