Other characteristics include a pH of 5.2, an 84-m-thick brine layer, and high levels of hydrogen sulfide. [8] [32] The Atlantis II Deep is among the largest Red Sea brine pools and has high temperatures (~68 °C), a pH of 5.3, and high metal content.
Lake Shala, in the East African Rift Valley. A soda lake or alkaline lake is a lake on the strongly alkaline side of neutrality, typically with a pH value between 9 and 12. They are characterized by high concentrations of carbonate salts, typically sodium carbonate (and related salt complexes), giving rise to their alkalinity.
The team found that bacteria seemed to be more prevalent in outdoor pools. [4] Furthermore, they noted that the higher the pH of the pool, the more bacteria were present in the water. 20.2% of the bacteria in the pools were found to be S. aureus. [4] Another study reported two experiments involving a large pool and a small pool. [5]
To kill pathogens and help prevent recreational water illnesses, pool operators must maintain proper levels of chlorine or another sanitizer. [10] [11] Over time, calcium from municipal water tends to accumulate, developing salt deposits in the swimming pool walls and equipment (filters, pumps), reducing their effectiveness.
A brine pool, sometimes called an underwater lake, deepwater or brine lake, is a volume of brine collected in a seafloor depression. These pools are dense bodies of water that have a salinity that is typically three to eight times greater than the surrounding ocean. Brine pools are commonly found below polar sea ice and in the deep ocean.

Alkalinity can be measured by titrating a sample with a strong acid until all the buffering capacity of the aforementioned ions above the pH of bicarbonate or carbonate is consumed. This point is functionally set to pH 4.5. At this point, all the bases of interest have been protonated to the zero level species, hence they no longer cause ...
Mono Lake (/ ˈ m oʊ n oʊ / MOH-noh) is a saline soda lake in Mono County, California, formed at least 760,000 years ago as a terminal lake in an endorheic basin.The lack of an outlet causes high levels of salts to accumulate in the lake which make its water alkaline.
