This can result in increased levels of pollution, algae growth, and changes in the availability of clean drinking water.

One of the main ways climate change affects water quality is through increased stormwater runoff. As temperatures rise, more precipitation falls as intense storms rather than light rain. This increases the amount of polluted runoff that enters rivers and streams, carrying contaminants like sediment, nutrients, and chemicals from fertilizers and pesticides.

Higher temperatures also contribute to higher levels of bacteria and harmful algal blooms (HABs). Warmer waters provide optimal conditions for bacteria growth, which can lead to contaminated drinking water sources and increased risk of waterborne illnesses. HABs occur when algae grow out of control due to high nutrient levels in the water. These blooms release toxins that can harm aquatic life and pose a threat to human health if ingested or contacted during recreational activities.

Climate change also has indirect impacts on water quality through altered hydrological cycles. As warmer temperatures increase evaporation rates, there is less moisture available for replenishing groundwater supplies. This can lead to saltwater intrusion into freshwater sources and reduced stream flow during dry periods, which concentrates pollutants and further decreases water quality.

In addition, changing precipitation patterns can affect agricultural practices and land use patterns. In Tennessee, agriculture is a major source of pollution from fertilizers, pesticides, manure runoff, and erosion. Changes in rainfall timing or amounts could affect agricultural runoff management techniques, potentially leading to increased pollution entering rivers and streams.

Overall, climate change poses significant threats to water quality in Tennessee through increased stormwater runoff, higher bacteria levels, HAB outbreaks, altered hydrological cycles, reduced stream flows, and changes in land use patterns.
