What is used to monitor pollution in rainwater?

Pollution in rainwater is typically monitored using a combination of laboratory analyses and field instruments. Common methods include sampling rainwater and testing for various pollutants such as heavy metals, nutrients, and pathogens. Sensors and probes can also be deployed to measure parameters like pH, turbidity, and electrical conductivity in real-time. Additionally, satellite imagery and remote sensing technologies are increasingly utilized to assess broader environmental impacts related to rainwater pollution.
