Why VA Loans Require Water Testing in North Carolina

The U.S. Department of Veterans Affairs enforces strict Minimum Property Requirements (MPRs) that ensure homes financed with VA loans are safe, sanitary, and structurally sound.

If a North Carolina property uses a private well, the VA requires water testing to confirm the water is safe for human consumption.

VA requires testing because:

  • Private wells are unregulated

  • Water conditions vary across NC counties

  • Local plumbing can introduce contamination

  • Wells can be impacted by age, construction quality, storms, rainfall, agriculture, septic systems, and groundwater changes

  • Many NC properties are rural and rely solely on well water

Bottom line:
If the home is served by a private well, a VA water test is mandatory.

The Required Water Tests for VA Loans in NC

The VA follows the EPA Safe Drinking Water Act standards.
In North Carolina, the most commonly required VA water tests include:

1. Total Coliform & E. coli (Mandatory for All VA Loans)

This is the #1 requirement and the first thing underwriters look for.

Why it matters:

  • Indicates whether the water is bacteriologically safe

  • Determines whether contamination may come from well casing, soil, septic system, or plumbing

  • Failing this section immediately stops the loan

What the VA requires:

  • ABSENT results for BOTH

  • Chain-of-custody documentation

  • Testing by a State & EPA-Certified Laboratory

This is non-negotiable.

2. Nitrate & Nitrite (Mandatory for All VA Loans)

Nitrates and nitrites come from:

  • Fertilizer runoff

  • Agriculture

  • Septic drainfields

  • Groundwater contamination

  • Older plumbing systems

EPA limits:

  • Nitrate: 10 mg/L

  • Nitrite: 1 mg/L

Anything above this fails VA requirements.

Heavy Metals (Lead, Copper, Iron, Manganese, etc.)

Most VA lenders in NC require metals testing when:

  • The house has older plumbing

  • Copper or galvanized pipes are present

  • The well is older

  • Prior tests in the area showed metal contamination

  • Underwriters feel additional data is needed

Many North Carolina lenders now default to requiring:

  • Lead

  • Copper

  • Iron

  • Manganese

This trend is increasing every year because underwriters prefer fewer conditions, not more.

Field Parameters (EPA-Recognized Measurements)

These are performed on-site by the certified sampling provider.

Common VA-accepted field parameters:

  • pH

  • Temperature

  • Turbidity

  • Conductivity (EC)

  • TDS (Total Dissolved Solids)

  • Free Chlorine

  • Total Chlorine

These are NOT lab tests — they are field observations required to support the integrity of the sample.

They prove:

  • The well is operating normally

  • Water is being drawn correctly

  • The sample is not artificially altered

5. Flow-Rate Testing (Often Required by NC VA Underwriters)

While not formally listed in the national MPR, North Carolina lenders frequently require flow-rate evidence.

Why?
Because a well that can’t maintain adequate water supply does not meet the VA’s minimum livability standard.

A typical NC VA threshold:

  • 3–5 gallons per minute (GPM) sustainable flow

  • Demonstrated recovery

  • Documented system pressure

If these numbers are poor, the lender may:

  • Request well repairs

  • Require a new well pump

  • Require a storage system

  • Deny the property altogether

Flow-rate testing is one of the most overlooked underwriting conditions — yet it's becoming increasingly common in NC.

Who Can Perform VA Water Testing in North Carolina?

This is critical, and many deals fall apart because someone used the wrong provider.

VA requires:

  • EPA-recognized field sampling

  • State-certified laboratory analysis

  • Chain-of-custody procedures

  • Proper sample handling

  • A lender-ready report

The following CANNOT perform VA-compliant tests:

  • Home inspectors

  • Realtors

  • Homeowners

  • Uncertified samplers

  • Pool supply stores

  • Pet-store water tests

  • Over-the-counter kits

  • Local municipal water offices (unless they run a certified lab)

VA loans demand professional sampling with legal documentation

What Happens If the VA Water Test Fails in NC?

If any result exceeds EPA limits:

  • The lender will not approve the loan

  • The water system must be corrected

  • A retest must be performed

  • Chain-of-custody must be followed again

Most common causes of failure:

  • Bacteria contamination

  • Shallow wells

  • Septic infiltration

  • Nitrate spikes after rainfall

  • Lead/copper leaching from old pipes

  • Poor well construction

  • Lack of well cap integrity

Typical remedies:

  • Shock chlorination / disinfection

  • Retesting

  • Plumbing repairs

  • Filter system installation

  • Well-head sealing

  • Drainfield repairs

The VA will not accept a property until the water passes.

How Long Are VA Water Test Results Valid in NC?

This is a top searched question.

The general VA guideline:

90 days, but many lenders shorten this to 30–60 days.

Reasons for shorter validity in NC:

  • Rapid groundwater changes

  • Heavy rain patterns

  • Bacteria fluctuations

  • Lender risk tolerance

Underwriters ultimately decide validity, and some require retesting if:

  • Closing dates move

  • The borrower changes

  • A contract extension occurs

There are weather-related contamination concerns

How Much Does VA Water Testing Cost in NC?

Prices vary based on:

  • Distance

  • Lab fees

  • Whether metals testing is required

  • Whether rush service is needed

Typical NC VA test ranges:

  • Standard VA test: Call

  • VA test with metals: Call

  • Next-Day service: Call

  • Pay-at-Closing: Call

Most buyers choose Pay-at-Closing to avoid out-of-pocket expenses.

Why Next-Day VA Water Testing Matters in NC

Closings don’t wait. And NC lenders are known for:

  • Last-minute conditions

  • Underwriting surprises

  • Missing documentation

  • Fast-paced loan processing

A Next-Day Water Report prevents:

  • Contract extensions

  • Delayed underwriting

  • Missed closing dates

  • Seller frustrations

High-demand areas like:

  • Wake County

  • Franklin County

  • Durham

  • Johnston

  • Halifax

  • Lake Gaston

…often require rush service simply due to volume.
