Cloudy Water & Turbidity Correction in Maryland, DC & Virginia

We eliminate sediment, trapped air, and high turbidity from residential well water. If your water looks milky water or dirty, we can identify the cause and restore your water’s clarity.

What is Cloudy Water? (And Is It The Same as Turbidity?)

Homeowners often ask us if “cloudy water” and “turbidity” are different things. Here is the breakdown:

What is Cloudy Water?

“Cloudy water” is the visual symptom you see in your glass. It is water that looks milky, opaque, or dirty instead of crystal clear. It is usually caused by suspended particles that are floating in the water rather than dissolving.

What is Turbidity?

Turbidity is the scientific measurement of that cloudiness. It measures how much light is blocked by the suspended particles.

  • Low Turbidity (< 1 NTU): Crystal clear (Safe standard).

  • High Turbidity (> 5 NTU): Visible cloudiness (Needs treatment).

Are They the Same?

Yes and No. “Cloudy water” is what you see. “Turbidity” is the number on your lab report. If you have cloudy water, you have high turbidity. To fix the visual problem, we must lower the turbidity number using filtration.

Four beakers display water samples with increasing cloudiness from left to right, labeled Low Turbidity on the clear sample and High Turbidity on the murkiest, cloudy water sample. An arrow shows the progression.

The 60-Second "Glass Test"

Before you buy a filter, you must identify the type of cloudiness. Perform this simple test at your kitchen sink:

  1. Fill a clear glass with cold water.

  2. Place it on a counter and wait exactly 60 seconds.

  3. Observe how the water clears.

Still having trouble let a expert in water testing at National Water Service  do this for you.

What Do My Results Mean?

Result A: The water clears from the BOTTOM up.

What it is: Trapped Air Bubbles (Milky Water).

The Verdict: Safe.

Explanation: This is physics, not contamination. It is usually caused by “Thermal Expansion” in your water heater or a surging well pump. No treatment is required unless you also smell gas.

Result B: Dirt or sand settles at the BOTTOM.

What it is: Sediment.

The Verdict: Needs Filtration.

Explanation: Your well screen may be failing, allowing grit to enter your pipes. This grit acts like sandpaper and will destroy your appliances.

Recommended Solution: Sediment Filter.

Result C: The water stays hazy, colored, or never clears.
(Note: These particles require advanced filtration as they do not settle on their own.)

What it is: True Turbidity or Colloidal Clay.

The Verdict: Call a Professional.

Explanation: These particles are electrically charged to repel each other and will never settle. A standard filter cannot catch them.

Recommended Solution: Injection System (KX Pros).

Harmful Effects of Cloudy Drinking Water

The "Hot vs. Cold" Check

The easiest way to diagnose your issue is to check which faucet is cloudy.

Scenario 1: Only My Hot Water is Cloudy

The Look: Milky white water that clears up after a minute.

The Cause: Trapped Air. Cold well water holds more oxygen. When it enters your hot water tank, the heat forces the air out as micro-bubbles.

The Verdict: Safe. This is physics, not contamination. No treatment is needed unless you smell sulfur (rotten eggs).

Scenario 2: My Cold Water is Cloudy/Dirty

The Look: Brown, yellow, or hazy water that may leave dirt at the bottom of the glass.

The Cause: Sediment or Turbidity. Your well is pumping sand, clay, or organic runoff into your home.

The Verdict: Needs Treatment. You need a filtration system to stop the dirt before it enters your plumbing.

Our Solutions for Cloudy Water

  • Water Testing: We perform an on-site analysis to measure NTU (Turbidity) levels and identify the contaminant.

  • Sediment Filtration: A spin-down mechanical screen that physically traps sand and grit before it enters your pipes. 

  • Multi-Media Systems: Large-tank filtration using layers of media to trap heavy sediment and organic debris. 

  • KX Pros: Our advanced “All-in-One” system that removes fine turbidity, iron, and manganese without chemicals. **This is our most effective solution for water that stays cloudy or milky after the glass test.**

  • Iron Breaker Sulphur Breaker (IBSB): The best solution if your cloudy water also smells like “rotten eggs” (Sulfur Gas).

  • Reverse Osmosis: The final step for drinking water. It removes ultra-fine particles for bottled-quality clarity.

Cloudy Water & Turbidity FAQs

Is cloudy water safe to drink?

If it is just air bubbles, yes. If it is Turbidity (dirt/clay), no. Turbidity can hide bacteria and viruses from treatment systems.

No. A softener removes dissolved minerals (calcium), not physical dirt. Sediment will clog a softener. You need a Sediment Filter or KX Pro installed first.

Often, no. Standard filters catch sand, but they miss Colloidal Clay (microscopic particles). We use Multi-Media or KX Pros to filter out that fine haze.
