Remote sensing involves collecting data about water quality using sensors mounted on satellites or aircraft. It is not a direct method of collecting water samples.

A water quality assessment aims to evaluate the overall health of a water body, identify potential sources of pollution, and monitor changes in water quality over time.

Radioactivity is not a common parameter measured in routine water quality monitoring. It is typically measured in specific cases, such as when there is a concern about radioactive contamination.

Grab sampling involves collecting a single sample at a specific time, while composite sampling involves collecting multiple samples over a period of time and combining them into a single sample.

Artificial intelligence models are not commonly used in water quality modeling. Empirical, mechanistic, and statistical models are more commonly employed.

Water quality criteria are used to set limits on the concentration of pollutants in water in order to protect human health and aquatic life, and to ensure that water is safe for drinking, swimming, and fishing.

Remote sensing is not a method for analyzing water quality data. It is a method for collecting data about water quality using sensors mounted on satellites or aircraft.

Point source pollution comes from a single, identifiable source, such as a factory or sewage treatment plant, while non-point source pollution comes from multiple, diffuse sources, such as agricultural runoff or stormwater runoff.

Flow sensors are not commonly used in water quality monitoring. They are typically used to measure the flow rate of water in a pipe or channel.

A water quality audit is conducted to evaluate the effectiveness of a water quality monitoring program, identify areas where improvements can be made, and ensure that data is being collected and analyzed correctly.

The Dissolved Oxygen Index (DOI) is not a common type of water quality index. It is a specific parameter used to assess the health of a water body based on its dissolved oxygen concentration.

A QA/QC program is used to ensure that data is accurate and reliable, identify and correct errors in data collection and analysis, and ensure that data is collected and analyzed in a consistent manner.

Water Quality Objectives (WQOs) are not common types of water quality standards. They are typically used in water quality planning and management, rather than as enforceable standards.

A water quality risk assessment is conducted to identify potential health risks associated with exposure to water contaminants, determine the likelihood and severity of adverse health effects, and develop strategies to reduce or eliminate health risks.

Remote sensing networks are not common types of water quality monitoring networks. They are typically used for collecting data about water quality from satellites or aircraft, rather than from in-situ measurements.
