Name and describe two human activities that have different negative effects on groundwater held in aquifers.
1. Industrial pollution: Industrial activities, such as manufacturing, mining, and oil drilling, can release harmful chemicals and contaminants into the ground. These pollutants can seep into groundwater sources held in aquifers, contaminating the water and making it unsafe for human consumption. This pollution can also damage the natural ecosystems that rely on groundwater sources.
2. Agricultural runoff: Agricultural practices, such as the use of fertilizers and pesticides, can lead to contamination of groundwater held in aquifers. When these chemicals are applied to crops, they can leach into the soil and eventually make their way into groundwater sources. Excess nutrients like nitrogen and phosphorus from fertilizers can also cause algal blooms in bodies of water connected to aquifers, leading to further contamination of groundwater. This can harm aquatic life and pose health risks to humans who rely on groundwater for drinking water.
