Purifying Polluted Water: A Human-Centric Approach

Water pollution is a pressing issue that endangers the health of millions of people worldwide. It occurs when harmful substances contaminate bodies of water, including rivers, lakes, and oceans, rendering the water toxic and unsafe for human use. This contamination can be caused by various factors, such as industrial and agricultural wastewater, oil spills, plastic pollution, and the release of chemicals and microorganisms. The consequences of water pollution are dire, leading to infections, health problems, and even deaths. With the increasing demand for freshwater and the challenges posed by climate change, addressing water pollution is crucial for ensuring the availability of safe drinking water and protecting human health.

Polluted water is an important resource for crafting acid

In the game Once Human, a multiplayer open-world survival game set in a post-apocalyptic future, Polluted Water is an important resource for crafting acid. Acid is used in crafting recipes for items such as Gunpowder, Ingots, and Batteries. To get Polluted Water, players must find contaminated water sources in corruption or pollution zones. These zones can be identified by a beeping sound and a fluctuating number displayed on the player's backpack or cradle. Players can then use a Water Pump from the "Production Processing" build menu to collect the Polluted Water. The Water Pump must be fully submerged in the contaminated water source and powered by Electric Eels.

It is important to note that the Water Pump in the "Special" section of the build menu is not suitable for this task, as it is meant for moving water upward. Additionally, players should have at least three or four Water Tanks to store the Polluted Water. This allows players to continue with other tasks while the Water Pump works passively.

One strategy for efficiently farming Polluted Water is to situate your base near areas abundant in Polluted Water. For example, the Ricci Securement Tower in Iron River and the lake next to the Gaia Research Center Ruins in the Broken Delta region are known to contain Polluted Water. Another strategy is to build a passive Acid farm by setting up Water Pumps in a polluted area and connecting them to Water Storage Containers. The polluted water can then be purified using an Osmosis Water Purifier, which converts it into Impure Acid. This Impure Acid can then be placed into a Brewing Barrel to create Pure Acid.

By utilising these strategies and resources, players can effectively use Polluted Water as a crucial component for crafting acid in Once Human.

Find polluted water in Chalk Peak, Broken Delta, Iron River, and Red Sands

Polluted water is a valuable resource in Once Human as it can be used to farm acid, which is then used to craft items like gunpowder, batteries, and ingots. There are a few locations in Chalk Peak, Broken Delta, Iron River, and Red Sands where you can find polluted water. Here are some specific places to find it:

Chalk Peak

You can find polluted water in the northwest region of Chalk Peak. The coordinates for this location are (-1187, -2267). It's important to note that this area is quite remote and far from other places of interest, so it may not be the most convenient location for your base.

Broken Delta

The lake next to the Gaia Research Center Ruins in the Broken Delta region is a good source of polluted water. This lake is located near a corruption zone, so your backpack will start glowing when you're close by due to the amount of contamination in the area.

Iron River

The Ricci Securement Tower in the Iron River region has a small underground base with polluted water. This area is popular for building bases, as players can position their bases half in polluted water and half in non-polluted water.

Red Sands

There are several locations within Red Sands where you can find polluted water. One is the Blackfell Fallen Zone, which has a large polluted lake with crocodiles. Another is just north of Fort Eyrie in Red Sands. Additionally, the beach next to the Alternate Reality Research Institute is extremely polluted and is a great place to farm acid and ores. The coordinates for the three areas in Red Sands are (4627, -1372), (4650, -2248), and (7595, -1062).

Remember, to collect polluted water, you will need to unlock water pumps from the Memetics tree. After collecting the polluted water, you can put it into an Osmosis Water Purifier to get pure water and impure acid. Then, by using a Brewing Barrel, you can turn the impure acid into pure acid.

Use a water pump in a contaminated zone to collect polluted water

To collect polluted water in Once Human, you need to use a water pump in a contaminated zone.

First, you need to find a contaminated zone. These are areas with high levels of pollution, often indicated by black patches on the map. One example of a contaminated zone is the beach in the top right corner of the map, in the desert zone. Another location is a huge lake beneath a cliff that overlooks the White Cliff settlement in the Blackheart region. You can also try going far out west, as there are huge swaths of land that are polluted.

Once you've found a contaminated zone, you need to place your water pump in the source of the pollution. This could be in the ground or in the water, as long as it is fully submerged. Make sure the pump is connected to water tanks on your territory to store the polluted water. You will know you are in a contaminated zone when your Cradle beeps and displays a number.

After placing the pump, it will automatically start collecting polluted water. You can then use an Osmosis Water Purifier to cleanse the water, which will give you Pure Water and Impure Acid. Putting the Impure Acid into a Brewing Barrel will then turn it into Pure Acid.

Collecting polluted water and turning it into acid is a slow process, so it is recommended to build a passive acid farm to ensure a steady supply of this valuable resource. Acid is essential for crafting items such as Gunpowder, Batteries, and Ingots.

Place the water pump in the water and fully submerge it

To get polluted water in Once Human, a multiplayer open-world survival game, you will need to use a water pump. This is because polluted water is collected from contaminated water sources using a water pump from the "Production Processing" build menu.

To use the pump, you must place it in the water and fully submerge it. This is because the water pump in Once Human is a submersible pump, which, as the name suggests, is designed to work with the entire assembly, consisting of the pump and motor, fully submerged in the liquid or medium to be processed. This is in contrast to a pedestal sump pump, which cannot be completely submerged as it is not sealed and can therefore short out the motor and create a shock risk in standing water.

To install the submersible water pump in Once Human, you must position it in the water and ensure that it is fully submerged. If it is not fully submerged, it will not work. Once the pump is in place, you can deploy Electric Eels to power it and begin the process of extracting polluted water.

It is important to note that while water pumps are great for extracting polluted water, you will need to have at least three or four water tanks to store the polluted water. This will allow you to freely continue your missions and perform other tasks while the water pump works passively in the background.

Store polluted water in tanks on your territory

Storing polluted water in tanks on your territory can be a practical solution, especially if you are in a desert or hot climate. Here are some key considerations and steps to follow:

Choosing the Right Tank

Select a suitable tank for storing polluted water. Ensure the tank is designed for water storage and manufactured for food use. The size of the tank will depend on your needs and the number of people you are supplying. The Utah Department of Environmental Quality recommends storing at least 1 gallon of water per person per day for two weeks. This includes half a gallon for drinking and food preparation and another half gallon for other uses like handwashing and dishwashing.

Tank Location and Setup

Choose a strategic location on your territory to place the tank. Consider accessibility and any potential risks. It is advisable to keep the polluted water tank separate from any clean water sources to prevent accidental mixing or contamination. You may also want to have multiple tanks for different purposes, such as one for germy water and another for non-infected polluted water, as suggested by some users.

Filling and Maintaining the Tank

When filling the tank, ensure the water source is relatively clean and disinfect the water if necessary. Regularly check the water quality and cleanliness of the tank. Sediment accumulation can contribute to the growth of microorganisms, so proper maintenance is crucial. Clean the tank at least once a year, and more frequently if needed. Additionally, consider installing a whole-house or point-of-use water filtering system for added protection.

Preventing Contamination and Odors

To prevent the spread of polluted oxygen and inhibit the growth of microbes, create a layer of CO2 on top of the polluted water. You can do this by locking a small space until enough CO2 is produced or using deodorizers and air fresheners near the tank. This will help control odors and prevent the polluted water from affecting your oxygen supply.

Using Polluted Water

Polluted water can be used for various purposes, such as cooling or as fertilizer. It can also be converted back into clean water through methods like boiling, using a water sieve, or with the help of Gulp Fish. Always be cautious when handling polluted water, and ensure it does not come into contact with your clean water supply.
