meghan DAVIS | spring 2022 4 abstract.
As a society we have become reliant on mass production and manufacturing. The emissions from this industry, which include carbon oxides, sulfur oxides, nitrogen oxides, and other harmful gases, linger in the atmosphere. These chemicals are not only destroying our air and environmental quality, but they are also threatening our fresh water sources. As air pollution worsens, climate change is triggered, causing sea levels to rise.
Because the rising sea levels will cause an unbalancing of the water aquifers, desalination plants will become paramount for freshwater consumption. Today, current desalination plants across the world produce 100 billion liters of water and 100 billion liters of brine each day. This brine must be significantly diluted in order to protect marine ecosystems and this process is extremely expensive to do well, so current desalination plants are destroying marine life.
The inevitability of a future excess of salt, in addition to the health benefits of this mineral warrant the exploration of salt as a means of rehabilitating the damage created by air pollution, at both a commercial scale and a personal scale.

health benefits of salt.
The health benefits of salt have been known and explored for centuries. Salt has the unique ability to detoxify, heal, cleanse, exfoliate and even hold in moisture, all in one. This mineral absorbs dirt, grime, toxins, and deeply cleanses pores. Salts are easily absorbed through the cell wall of our skin and stimulate antiinflammatory reactions and replenish lost minerals which are lost during daily routine.
Salt helps protect mucus membranes, as the first line of defense against virus and bacteria. High concentrations of salt make the mucus less penetrable and high concentrations of salt kill some types of bacteria through dehydration. The antibacterial function of salt works through osmosis; when bacterial cells become dehydrated, they lose structure and die.
Research has found halotherapy to assist in the treatment of: Lung infection, Throat infection or pharyngitis, Smoking-related breathing problems, Respiratory allergies, Asthma, Bronchitis, Cold or cough, Pneumonia, Sinusitis, Rhinitis, Tonsillitis, Cystic fibrosis, and breathing problems caused by Covid-19. In addition, halotherapy can help repair skin cells and protect skin from aging and infection.
Our bodies contain the same concentrations of minerals and nutrients as the salty sea water. Magnesium, potassium and calcium are additional minerals found in sea salt. They help combat bacteria and skin infections, while also speeding up the healing process.

rising sea levels.
As air pollution worsens, climate change is triggered, causing sea levels to rise. Within the last three decades, the rate at which the sea level is rising has raised to 0.14 inches, from a previous rate of 0.06 inches. This may not sound like a lot, however, at this rate, by the year 2100 it is predicted that the sea levels will have risen a minimum of 3 feet. This would mean that at least 10 major cities, including New York City and Boston will be underwater by 2100. If sea levels rise enough to drown cities, they will be high enough to destroy our fresh water sources.
For the city of Los Angeles alone, it requires fresh water from three different ground water basins. Due to pollution and overextraction, these water basins are being destroyed, along with similar ones all over the world. The storage for this capacity of fresh water would cost $3 billion. This is only 16% of the total water needed for the population of Los Angeles.

2. materials exploration.
meghan DAVIS | spring 2022 18
In order to understand the properties which are unqiue to the material, a series of experiments were performed. Salt struggles in creating spatial qualities of its own, but when used in conjunction with other materials, a world of possibilities manifests. The first experiments began by spraying a salt water solution on various materials. From there, materials were then submerged in a similar solution. From preliminay research it is known that salty filament for 3-D printing is being explored and tested. Various forms of compression structures have also begun to emerge in experimental research, so this warrated the testing of small scale blocks and arches. And because salt is a mineral, the uniqure properties of the material afford the opportunity for mineral accretion through electrification.

3. architectural synthesis

The buildings’ form is inspired by salt crystallization formation. The ground level serves as a multi-sensory learning center, which was inspired by the multi-sensory nature of salt health benefits. The desalination plant is located above the learning center, with various reveals between programs. The desalination plant serving as a ‘bridge’ between production, education and research is a tribute to the chemical bonding that happens in the creation of salt. A large exterior space is dedicated to pavilions and forms utilizing salty materials, functioning as a landing place for collaboration and exploration of salty structures.
The building is nestled in the center of two intesecting pedestrian bridges, with three moments where small dam structures create hydrelectric power, in order to help power the entire complex. The pedestrian bridges connect two parks which are located across the river from each other, promoting an overall health based lifstyle.
Ideally, these complexes would appear all over, but for the sake of this thesis, the complex is located on the Los Angeles River in California. This river is located just north of San Pedro Bay, which is a unique port that’s split between Los Angeles and Long Beach and is actually the largest port utilized on the west coast of the U.S. This site was chosen due to the milder climate, in conjunction with the poor air quality and high amounts of production in this area.

site conditions.
Los Angeles provides an ideal site for the Just +Salt complex. With a milder climate, water levels are less variable. The location’s poor air and enviornmental quality will not only be benefitted by, but necessitates the goal of rehabilitating damge caused by air pollution. The poor water quality proves the necessity for both desalination and rehabilitation.

Los Angeles’s first settlers relied on the Los Angeles River as their main fresh water source.
1889 San Pedro Bay was chosen as the city’s harbor, requiring an extensive railway system to and from the ports.
1913
The Los Angeles Aqueduct opened, meaning the Los Angeles River was no longer required as a fresh water source.
1938
The most disatrous of a history of floods devastated much of the city, triggering change.
1938
A concrete channel was installed as the basis for the river in order to mitigate flooding issues.
