McFarland turbidity standards are a set of reference solutions used to quantify the turbidity of microbial suspensions, particularly in laboratories. These standards consist of a series of dilutions of barium sulfate or sulfuric acid that produce a range of turbidity levels, typically measured in a nephelometer. The most commonly used standard is the 0.5 McFarland standard, which corresponds to approximately 1.5 x 10^8 bacterial cells per milliliter, making it a useful tool for standardizing bacterial inoculum concentrations in microbiological testing.

turbidity is pollution, thus runoffs and fertilizer and anything that makes up pollution is turbidity.

Turbidity in sand can be tested by taking a sample of the sand and mixing it with water in a clear container. After stirring the mixture, observe how quickly the water clears up — the longer it takes for the water to clarify, the higher the turbidity of the sand. Additionally, turbidity can also be measured using a turbidity meter, which provides a numerical value of turbidity in nephelometric turbidity units (NTU).

The unit of turbidity is typically expressed in NTU (Nephelometric Turbidity Units) or FTU (Formazin Turbidity Units). Turbidity is a measure of the relative clarity of a liquid and indicates the amount of suspended particles in the water.
