A Detectable Leak Rate is the smallest leak (from a storage tank), expressed in terms of gallons- or liters-per-hour, that a test can reliably discern with a certain probability of detection or false alarm.

In the context of the environment, "detection" refers to the process of identifying or recognizing the presence or occurrence of certain elements, phenomena, or changes in the environment. It involves using various techniques, tools, and methods to observe, measure, and analyze environmental conditions. Detection plays a crucial role in understanding and managing environmental issues, including monitoring natural resources, assessing pollution levels, and studying ecosystem dynamics.

A Detection Criterion is a predetermined rule to ascertain whether a tank is leaking or not. Most volumetric tests (volumetric tank tests) use a threshold value

The Detection Level is the lowest "measurable” analyte Concentration by a specified method. By improving our technologies, we are also lowering the detection level for nearly all methods.

A Detection Limit is the lowest Concentration of a chemical that can reliably be distinguished from a zero concentration.

A detector (sensor) is a transducer whose purpose is to sense (that is, to detect) some characteristic of its environs. It detects events or changes in quantities and provides a corresponding output, generally as an electrical or optical signal; for example, a thermocouple converts temperature to an output voltage.

A Detention Time is 1. The theoretical calculated time required for a small amount of water to pass through a tank at a given rate of flow.

A Detergent is Synthetic washing Agent that helps to remove dirt and oil. Some contain compounds which kill useful Bacteria and encourage Algae growth when they are in wastewater that

Detoxification in the environmental context refers to the process of removing or neutralizing harmful substances (toxins) from the environment, including air, water, soil, and living organisms. These harmful substances can include pollutants, chemicals, heavy metals, and other contaminants that pose risks to ecosystems and human health. Detoxification can be achieved through natural processes or human intervention using various technologies and methods.
