Why Is Your Water So Murky? Here Are 3 Possible Causes

If you’ve noticed that your water has been looking cloudier than usual lately, don’t fret! That doesn’t necessarily mean there’s a problem with your plumbing system; it could just be due to one of the many factors that can cause turbidity in water. Learn more about turbidity and its causes right below.

What Is Turbidity?

Turbidity (sometimes called cloudiness) can occur naturally in water, but it can also result from the presence of impurities. In many cases, turbidity causes no harm to human health, but there are steps you can take to restore clarity to cloudy water or prevent your water from becoming cloudy in the first place. Experts utilise specialised instruments called turbidity analysers to measure turbidity in water. Here are three common causes of turbidity to help you figure out what might be going on.

Causes of Turbidity:

1.      Sediment

Sediment is one of the most common causes of turbidity in water. It can occur naturally or as a result of human activity. Sediment can be introduced into a water source through runoff from nearby farmland, construction sites, and other sources.

The sediment often consists primarily of sand, clay, or organic matter that has been eroded by rainwater runoff from hard surfaces such as roofs and roads. When it enters the source, the sediment can cloud the water with particles that are suspended in it.

2.      Algae

Algae, a type of living organism that is typically green, can cause water to appear murky. Algae are usually harmless, but their presence can make the water smell and taste bad. If you suspect your water contains algae, contact your local water agency for more information.

Algae and other types of aquatic plants can cause water to become turbid. Algae is most often found in lakes, ponds, and slow-moving streams. This type of algae grows in shallow water that is warm and nutrient-rich. The warmer the water, the more algae will grow.

3.      Erosion or Runoff

Erosion and runoff are two common causes of turbidity in water. Erosion happens when soil is eroded by rain or wind. Runoff occurs when rainwater flows over the surface, picking up and carrying sediments from the soil. This sediment can be anything from silt and clay to small rocks. If there is an area where erosion or runoff occurs, it will contribute to turbidity in the water found downstream. In this case, a turbidity meter can come in handy. Turbidity analysers can ensure the safety of everyone.

How Does Turbidity Measurement Help?

Turbidity is measured in Nephelometric Turbidity Units (NTU). It’s the measure of light that cannot pass through the water because suspended matter in the liquid blocks the light's passage. The higher the NTU reading, the poorer the water quality. Health risks posed by turbid water can include stomach upset and diarrhea, as well as a risk of infection from microorganisms. Turbidity analysers have become a necessity these days across various industries.

When the water coming out of your faucet takes on an opaque, cloudy hue, it might be hard to tell if it’s safe to drink or not. If you specialise in a profession that involves water treatment, turbidity analysers are an inevitable tool in the filtration process.
