What practice can help in tracking point source pollution?

Regular environmental audits are a critical practice for tracking point source pollution because they involve systematic reviews and assessments of environmental conditions and compliance with regulations. During these audits, data can be collected regarding potential pollutants, emission sources, and the efficacy of existing pollution control measures. This comprehensive approach allows for the identification of specific locations or practices that may be contributing pollutants to the environment.

While monitoring rainfall patterns can provide insights into how precipitation can affect the dispersion of pollutants, it does not pinpoint the sources of pollution directly. Similarly, while GPS technology is useful for mapping locations and tracking movements, it does not intrinsically measure or assess pollution. Analyzing water samples is also important in identifying pollutants and their concentrations, but it typically provides a snapshot of current conditions rather than a broad overview of compliance and environmental health over time. Regular environmental audits encompass these various elements and allow for a more thorough investigation and reporting of pollution sources.
