Is Well Water Safe to Drink? What You Need to Know

Well Water vs City Water Regulation

City Water (Public)

• Regulated by EPA under Safe Drinking Water Act
• Tested multiple times daily
• Treatment required to meet standards
• Violations must be reported to public

Private Well Water

• NOT regulated by EPA
• Homeowner responsible for testing
• No required treatment
• Quality varies by location

What This Means

Private well water can be excellent quality—often better than city water. But it can also have problems you don't know about unless you test. The responsibility is yours.

How to Test Your Well Water

Minimum Annual Testing

• Coliform bacteria: $25-$50
• Nitrates: $25-$40

These are the most critical health tests.

Every 3-5 Years

• pH, hardness, TDS
• Iron, manganese
• Any local concerns (arsenic, radon, etc.)
• Cost: $100-$300 for comprehensive panel

Test Immediately If:

• Water changes color, taste, or odor
• After flooding or well work
• Household illness of unknown cause
• Nearby contamination event

Where to Test

• State-certified labs (most reliable)
• County health departments (often free/low cost)
• Private labs

Treatment Options

Almost any water quality issue can be treated. Common solutions:

Bacterial Contamination

• Shock chlorination ($100-$300)
• UV disinfection ($500-$1,500)
• Continuous chlorination ($1,500-$3,500)

Nitrates

• Reverse osmosis at tap ($300-$800)
• Whole-house RO ($2,000-$5,000)

Arsenic

• Specialized arsenic filter ($1,000-$3,000)
• Reverse osmosis

Hard Water

• Water softener ($1,500-$4,000)

Iron/Sulfur

• Oxidizing filter ($800-$2,500)
• Aeration system ($1,500-$4,000)

Advantages of Well Water

Benefits Over City Water

• No chlorine: Fresher taste, no chemical smell
• No fluoride: Unless naturally occurring (some prefer this)
• No monthly bill: Water is essentially free after well installation
• No restrictions: No drought restrictions or tiered pricing
• Mineral content: Natural calcium and magnesium
• Independence: Not affected by water main breaks

Why Many Prefer Well Water

When properly maintained and tested, well water is often preferred for its taste and purity. It comes directly from the aquifer without traveling through miles of pipes or treatment plants.

We service all major pump brands including Franklin Electric, Grundfos, Goulds (Xylem), and Sta-Rite (Pentair). Our trucks carry common parts and components for same-day repairs.

Frequently Asked Questions

Is well water safe to drink?

Most well water is safe, but testing is essential. Private wells aren't regulated, so you're responsible for ensuring safety through regular testing and treatment if needed.

How do I know if my well water is safe?

Test it. There's no other way to know. Annual bacteria and nitrate tests are minimum. If it passes, it's safe.

Is well water healthier than city water?

It can be. Well water has no chlorine or added chemicals. However, untreated well water could have natural contaminants. The key is testing to ensure quality.

What percentage of well water is contaminated?

Studies suggest about 20-30% of private wells have at least one contaminant above recommended levels. Most issues are treatable. Testing identifies problems.

Can you get sick from well water?

Yes, if it contains bacteria or other pathogens. This is why annual bacteria testing is critical. Properly maintained wells rarely cause illness.

Should I filter my well water?

Depends on what's in it. Many wells need nothing beyond a sediment filter. Others benefit from softening or other treatment. Test first, then treat based on results.
