Large ponds take in brine and expose it to sunlight and
evaporation

The evaporation ponds concentrate salt and evaporate water
until only solid and bittern salts remain

How Evaporation Ponds can Control Salinity at the Salton Sea
Salton Sea
Inflow to Sea: water + salt
No outflow: salt accumulates
Water + salt removed to evaporation ponds:
Water evaporates
Salt remains on shore
![Page 11: Solar Evaporation Ponds at the Salton Sea for Salinity Control](https://reader036.vdocuments.us/reader036/viewer/2022062422/56813a30550346895da21829/html5/thumbnails/11.jpg)
Possible Conceptual Design for Solar
Evaporation Ponds
![Page 12: Solar Evaporation Ponds at the Salton Sea for Salinity Control](https://reader036.vdocuments.us/reader036/viewer/2022062422/56813a30550346895da21829/html5/thumbnails/12.jpg)
Salt is stored where it is deposited, and the pond levees are built higher to
accommodate it
![Page 13: Solar Evaporation Ponds at the Salton Sea for Salinity Control](https://reader036.vdocuments.us/reader036/viewer/2022062422/56813a30550346895da21829/html5/thumbnails/13.jpg)
Bittern salts may not be solid, but they make up a very small
volume
Bittern ponds

Lands affected would be
adjacent to, or close to, the existing Sea
margins

Potential accumulation of contaminants in concentrators
and solid salt deposits
Selenium Pesticides Metal residues Other agricultural chemicals such
as fertilizers
Preliminary indications are that these issues will not prove to be problems
for solar evaporation pond implementation
