If bleach contains perfumes or other substances, treated water won't be really |

Alright, then add in scented bleach too. |

"Clean" for the purposes of not being parasitic/contaminated. Lavender or Mountain Spring-smelling water seems pretty minor for the capful of bleach added to a giant tank of water. :) |

I have a additional suggestion. Most houses will contain scented bleaches and there's will be really low chance to regular bleach appear. Player can unscent bleach by himself, using fire or something otherwise hot enough for cooking, two bottles (one with bleach, other empty) and some time and cooking 1. Scented bleach can't be used to disinfect water, but unscented bleach can be used to create "disgusting water". It is clean as clean water, but adds morale debuff and it much less quenching than clean water. |
Why? It is exactly the same liquid just with clorine odour? |

Do we really need to distinguish between scented and unscented bleach? It already doesn't get in the way of chemical recipes involving it. |

Ok I did some thinking: If you were going to add a recipe for it, the numbers would be pretty big. Assuming that the bleach found in the game has the same concentration as 6% Bleach (e.g. regular bleach such as Clorox Regular Bleach), both the US EPA and Clorox websites say to use 2 drops per quart or 8 drops per gallon, which is 2 to 2.12 drops per liter. Rounding down to 2 drops per liter and using 1 drop = 0.05mL, then 1 portion of bleach is is 2500 drops Since the recommended bleach to water ratio varies slightly depending on how much water you are purifying, its fair to say those calculations are off - especially so with the use of a "drop" as a base unit. Looking it up online, I've found two different sites stating that 1 gallon of bleach can be used to purify 3800 gallons of water or more, which is approx. 14384.56L Using this extra conservative estimate that still gives us more than 1700 portions of clean water for every portion of bleach, which is still not very reasonable. To make it workable you can either add a recipe for diluted bleach which would then be used to purify reasonable amounts of water OR you can change the portion size of bleach to something smaller and adjust existing crafting recipes accordingly. If you add a diluted bleach recipe and use that for treating water, we need to figure out how much to dilute. Its still a lot of water per portion of bleach, and no matter how you adjust it by tweaking the definition of portion volumes or diluted solutions, the fact remains that you can purify a large amount of water with a very small amount of bleach. Since bleach is easily found in the game, and it only takes a tiny amount of a single instance of it to purify lots of water, I think it will always throw off the balance of the game. But that doesn't mean you can't add bleach based water purification without breaking the game balance. You could simply add a recipe using (what would be lethal) amounts of bleach to purify more manageable amounts of water for the sake of game balance - although I personally don't like this since the main reason to add the recipe in the first place is to be more "realistic." Considering that there are multiple other ways to purify water in the game, I don't think it's usefulness outweighs the oversimplification. Alternatively, a potentially balanced and realistic solution could be to add a recipe for "inefficiently" crafting water-purification tablets using bleach. I don't know what other ingredients go into water purification tablets aside from iodine or chlorine or the process to make them - or even if making them using bleach is feasible - but someone who knows might be able to come up with a realistic-enough recipe. Another way to implement it could be to make a bleach-fueled water purification device. Essentially, you put water in the tank and the tank "dispenses" the necessary amount of bleach to purify the water from a built in bleach reserve. Sodium hypochlorite breaks down at varying rates according to temperature, concentration, pH, the presence of salt (which is a product of the breakdown), and presence of heavy metals. Since bleach in game is certainly not kept at room temperature, and any bleach crafted by the player would still contain large amounts of salt compared to commercial bleach, you can assume in-game bleach has a very limited window where it is strong enough to reliably disinfect water. This way we can justify that the bleach fueled water purification device needs periodic restocking of fresh bleach, regardless of how much water you purify. It could be implemented as vehicle part or furniture that has a bleach reserve component that needs to be reloaded after a period of time, and a water tank that gets loaded with water which is then turned to clean water after about 30min in game and can be dispensed whenever. Of course none of this takes into account the fact that using bleach to purify water only disinfects it and doesn't remove toxic chemicals/metals/large particles like boiling and filtering do. Additionally, treating water with bleach takes longer than boiling or filtering and relying on bleach treated drinking water for more than a few weeks can cause serious health issues. Regarding the health issues: you could make a "bleachy water" recipe that is something like 1 portion of bleach with 10 portions of water but will make the character sick as if they drank bleach unless they have the poison resistant trait. |

The breakdown process is IMO sufficient, I'm fine with bleach providing a reliable way to mass-disenfect water that only works in the first year of the cataclysm. Considering the ratios involved, I'd propose the bleach acts without being consumed in all but the largest quantities (up to 250l or so), and batches that large just round up, no real need to be precise here, it's effectively limitless if you find just a few bottles of bleach. If that's not sufficient, we could add water tainted with toxins and more stringent requirements to clean it. |

Another approach is to just make bleach turn water from dirty to poisoned (if we have a mild poisoned version of water) So you'll get some side effects but it's better than dying of thirst |

Only if you're impatient enough to not wait for 30 minutes and/or poured in
too much bleach. It's relatively safe as long as it's not drunk in large
amounts.

And if you have to provide a negative to bleached water, just give it a
small cut to sanity because of the bad taste from the bleach.

@Ska-Riot As mentioned above scented, color safe, or bleaches with added cleaners are all considered toxic by the EPA (with good reason) and are likely to cause poisoning of some kind. In addition if all bleach was good for cleaning water it would throw off the balance in the game. But making it cause mild to moderate poisoning allows you to choose to mitigate risk, guaranteed bad effects to avoid the possibility of something worse you can't deal with yet (since if you were far enough to deal with parasites you could probably boil or filter water without issue), without making it the best solution across all times in the game. |

No discussion in over half a year, closing. |
Title
It's minor, but IRL you can use bleach to purify water, but the option to do so is not in this game.
