why are fracking liquid waste pools harmful to the environment?
can evaporate into the air and contribute to
when fracking liquid waste is left in pools on the surface,
pollution.

Fracking liquid waste - type of waste produced during hydraulic fracturing in oil drilling operation - comprises a large fraction of salts, hydrocarbons, radioactive materials, and carcinogens. Many of these chemicals (e.g. benzene, toluene, etc) are able to vaporize at ambient environmental conditions, thus making the environment polluted. If they are left untreated in the pit lakes or pools, they are a serious threat to the local fauna and flora. This is because of their toxic, mutagenic, and teratogenic properties.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
