[1] Evaporation ponds are inexpensive to design making them ideal for multiple purposes such as wastewater treatment processes, storage, and extraction of minerals.
[4] Evaporation ponds at contaminated sites remove the water from hazardous waste, which reduces its weight and volume and allows it to be more easily transported and stored.
[3][4] Evaporation ponds are used to prevent run off agricultural wastewater contaminants like pesticides, fertilizers and salts from entering bodies of water they would normally flow into.
[2] Evaporation ponds pose a threat to environmental sustainability because resources like water, land, and minerals are rapidly used at large scales.
An increasing demand for extracted products and treated wastewater will result in evaporation ponds expanding and related issues worsening until the depletion of these resources.
[2] Evaporation ponds are found to increase green house gas emissions and therefore contribute to environmental issues like warming of the planet and ocean acidification.
