What do the Clean, Low, Watch and Swap levels mean?

They are cut from a continuous concern level the app computes from the sourced claims that the chosen evidence lens shows: each claim counts its concern class, tier weight, confidence and dose relevance, combined worst-first with a decay so one serious finding outweighs many small ones, then scaled by how much of the substance reaches you in this use. Clean is below 0.35, Low below 1.1, Watch below 2.0 and Swap above that, on a 0 to 3 scale.

Is Trichloroacetic Acid safe in drinking water?

Q: Is trichloroacetic acid safe in drinking water?

Under the app's default Cautious lens, trichloroacetic acid in drinking water rates Swap: the app would put this near the top of your swap plan. 3 sourced concerns count (suspected carcinogen, consensus tier; oxidation by-products, consensus tier; endocrine, emerging tier). This is research with sources, not medical advice.

Water1 use researched3 sourced claims

Where it turns up: haloacetic acid, regulated disinfection byproduct. Detox My Life researched trichloroacetic acid under one use, because the same substance means something different in each use. Every claim below carries its evidence tier, how sure the research is that it applies here, and the sources it cites. The level is computed by the app's own deterministic engine, so the page says exactly what the app would.

Sourced concerns (3)

ConsensusSuspected carcinogenconfidence 90%

The U.S. Environmental Protection Agency (EPA) classifies trichloroacetic acid (TCA) as a probable human carcinogen based on studies showing its ability to cause liver tumors in laboratory animals.

Why here: TCA is a common disinfection byproduct formed when chlorine or other disinfectants react with natural organic matter in drinking water.
What would have to be true: Ingestion of drinking water containing TCA, particularly above the EPA's Maximum Contaminant Level Goal (MCLG) of 0.02 mg/L (20 µg/L) for TCA, or the regulated sum of five haloacetic acids (HAA5) at 60 µg/L.
The other side: The International Agency for Research on Cancer (IARC) classified trichloroacetic acid in Group 3, meaning it is 'not classifiable as to its carcinogenicity to humans', noting limited evidence in experimental animals for its carcinogenicity and inadequate evidence in humans.

ConsensusOxidation by-productsconfidence 100%

Trichloroacetic acid (TCA) is a common disinfection byproduct (DBP) formed in drinking water when chlorine or other disinfectants react with natural organic matter present in the source water.

Why here: TCA is an unavoidable byproduct of the widely used chlorination process for disinfecting municipal water supplies.
What would have to be true: Universal exposure of the population to low levels of TCA results from its occurrence as a contaminant of drinking water disinfected by chlorination.

EmergingEndocrineconfidence 80%

Studies have suggested possible links between haloacetic acid exposure, which includes TCA, and adverse reproductive outcomes such as reduced birth weight and increased risk of birth defects, particularly in vulnerable populations like pregnant women and infants.

Why here: TCA is present in drinking water, leading to potential chronic exposure through daily consumption.
What would have to be true: Ingestion of drinking water containing haloacetic acids, including TCA, with animal studies showing effects at high doses in maternal diets.
The other side: While animal studies have shown adverse reproductive effects, human studies are limited, and the EPA's classification of TCA as a probable human carcinogen is based on animal studies, not specifically reproductive toxicity in humans.

Not researched here

The engine has no dossier for trichloroacetic acid when cooked with heat, in cold food, as a finishing ingredient, in heated food packaging or other uses. The app researches an ingredient for the use it infers from your product, so a scan fills these in; this page only shows what has already been researched and source-verified.

This is research, not medical advice. Detox My Life shows sourced claims sorted by evidence tier. It does not diagnose, treat, or tell you to start or stop anything. Talk to a qualified professional about your health.

Scan your own. The app reads any product label with your camera, works out how you are about to use it, and researches every ingredient for that use with live sources. Every scan adds to a Detox Score for your home, where 50 is a typical home in your region, and a plan of next swaps.
