Organic compounds in wastewater primarily consist of carbon-containing substances. These compounds are essential in assessing water quality as they are associated with the biochemical activity in the treatment process. The fundamental components that typically make up organic compounds are carbon, hydrogen, and oxygen. These elements combine in various ways to form a vast array of organic molecules, such as carbohydrates, proteins, and lipids, all of which can be present in wastewater.

The presence of nitrogen and phosphorus is significant in wastewater treatment, but they do not directly classify as organic compounds in the same manner as carbon-based compounds. While nitrogen can certainly be found in organic compounds (amino acids, for instance), it is not solely an indicator of organic content when standing alone. Helium, on the other hand, is an inert gas and does not participate in organic chemical bonding as it lacks the requisite valency.

Recognizing that organic compounds are carbon-based and often contain hydrogen and oxygen helps clarify why this specific grouping is essential in wastewater analysis. Identifying and managing these organic materials is crucial for effective treatment processes since they can exert a significant biochemical oxygen demand (BOD) on a wastewater treatment system.
