Is it impossible to track sources of pollution so using drains for disposal often hides an automobile mechanical shop's wastes?

While tracking sources of pollution can be challenging, it is not impossible. Many environmental monitoring techniques, such as water quality testing and tracing pollutants back to their sources, can help identify where waste from an automobile mechanical shop is entering the drainage system. However, using drains for disposal can obscure these sources, making it harder to hold businesses accountable for their waste. Effective regulations and monitoring are essential to prevent such practices and protect the environment.
