Failed Test? Here’s What Happens
1. Schedule
Call or submit the request form with the property address, the contact for the conventional lender, and the closing date. We confirm timing, lender-specific requirements, and rural property access details before sample collection.
2. Sample and Submit
A trained Well Water NC technician collects the water sample on-site as a disinterested third party, completes chain-of-custody documentation, and submits the sample to a North Carolina state-certified laboratory.
3. Deliver and Close
Conventional-formatted documentation is delivered to your closing team — buyer, lender, real estate agent, or closing attorney. If the sample fails, we coordinate disinfection, retesting, and recertification using only the source-level corrective actions that Conventional accepts.
Most failures are fixable.
Common Issues:
Inactive systems
Plumbing contamination
Environmental conditions
Well Water Fix
Disinfection (chlorination)
Flush + retest

Frequently Asked Questions
-
Conventional loans do not have a universal federal requirement, but many lenders require well water testing to confirm the water is safe and potable. Requirements are set by the lender, underwriter, or investor guidelines.
-
Water testing requirements are typically determined by the lender, underwriter, or loan investor (such as Fannie Mae or Freddie Mac), along with any applicable local or state health authority standards.
-
Most conventional loan water tests include:
Total coliform bacteria
E. coli
Nitrates
Nitrites
Lead
Additional testing may be required depending on the property location or lender conditions.
-
There is no fixed rule, but most lenders accept water test results that are 30 to 90 days old. Some may require more recent results depending on underwriting conditions.
-
In most cases, lenders prefer or require the sample to be collected by an independent third party. This helps ensure accurate results and avoids conflicts of interest during the transaction.
-
A failed test does not automatically stop the deal. The issue is typically corrected through disinfection, flushing, or minor repairs, followed by a retest. Once the water passes, the transaction can proceed.
-
No. Most lenders require the water source itself to pass testing. A filtration system alone usually does not satisfy loan requirements unless specifically approved by the lender.
-
Not always, but some lenders or appraisers may require verification that the well provides adequate water supply. When required, flow rates of 3–5 gallons per minute (GPM) are commonly expected.
-
Yes. Next-day results are often available depending on lab processing times and sample drop-off schedules. This is commonly used for tight closing timelines.
-
Yes, but shared wells must meet lender requirements. This may include:
Adequate water supply
Proper agreements between properties
Ability to isolate each property’s water line

Location
