Chlorine-based chemicals can leach into nearby water sources, posing risks to drinking water supplies and aquatic life. Studies have shown that exposure to high levels of chlorine compounds can be toxic to fish and other aquatic organisms, leading to population declines and disruptions in the natural balance of ecosystems.

Furthermore, the persistence of chlorine compounds in water bodies can have long-lasting effects. Unlike some other chemicals, chlorine-based disinfectants do not readily break down in the environment. This persistence means that even small traces of these compounds can accumulate over time, leading to chronic exposure for both wildlife and humans. The potential for bioaccumulation in the food chain is a significant concern, as chlorine compounds can accumulate in organisms and potentially affect higher trophic levels.

To mitigate the risks associated with chlorine compounds, alternative fracking fluids and treatment methods are being explored. Some companies are developing biodegradable fluids or using natural, non-toxic chemicals that minimize the environmental impact. Additionally, advanced water treatment technologies can help remove or neutralize chlorine compounds from wastewater before it is discharged or reused. It is crucial for the fracking industry to adopt these safer practices to protect water resources and ensure the long-term sustainability of energy production.
