What is Turbidity In Drinking Water?

Have you ever wondered what exactly is “turbidity” and what does it mean to your drinking water?

Simply stated, turbidity is the principle characteristic of water and an expression of the optical property caused by suspended matter or impurities that interfere with the clarity of the water.

These impurities might include:

  • Clay
  • Silt
  • Sediments from erosion
  • Algae
  • Urban runoff
  • Organic Compounds
  • Inorganic Compounds
  • Plankton and other microscopic organisms

Typical sources and causes of Turbidity include:

  • In groundwater, it is often caused by mineral particulates including reduced iron, clay, and silt.
  • In Surface water it is most likely suspended sediments or organic particulate.
  • In In distributed water, it is most often caused by sediments and biofilm releases or from backflow of unsafe water or cross connections.
  • Surface water turbidity increases during rainfall, which stresses the load on the treatment process.

What are the Health Concerns of Turbidity?

Turbidity is a key indicator of particulates in your water, to which microorganisms attach. Microorganisms that are bound to particulates are more protected from and resistant to the chlorine disinfectant process, making home water filtration very important.

What are the Guidelines for Turbidity?

The World Health Organization establishes that the turbidity of drinking water shouldn’t be more than 5 NTU, and should ideally be below 1 NTU.

How do You Treat Turbidity?

To date, home water filtration technologies are the best treatment for reducing turbidity. Conventional coagulation, flocculation and granular filtration as well as direct filtration are effective. Membrane technologies including microfiltration, ultrafiltration, nanofiltration as well as reverse osmosis, are also very effective.
