The selection of sampling locations is critically influenced by proximity to potential sources of pollution and hydrological features. This is important because locations near pollution sources, such as industrial areas, agricultural runoff, or wastewater discharge points, are more likely to have water quality issues that need to be monitored. By focusing on these areas, sampling efforts can more effectively assess environmental impacts and identify contamination risks.

Moreover, hydrological features such as rivers, lakes, and groundwater recharge areas play a significant role in how pollutants disperse and how water quality varies across a region. Sampling near these features ensures that potential influences on water quality are captured, thus providing valuable data for decision-making and regulatory compliance.

In contrast, randomly selecting sites across the region might overlook critical areas of concern, and only considering accessibility can lead to gaps in data that may not represent the actual conditions of the water quality. While historical sampling can inform site selection, it does not necessarily account for current environmental changes and emerging pollutants. Thus, considering key factors like pollution sources and hydrological features is vital for effective and relevant water quality monitoring.
