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.
Mainstream shows consensus claims only; Cautious adds emerging research; Based adds fringe claims, labelled as such. The last column counts, under Cautious, the sourced concerns, the findings in its favour and the fringe claims Based would add.

ConsensusSuspected carcinogenconfidence 100%
Disinfection byproducts, such as trihalomethanes (THMs) and haloacetic acids (HAAs), formed when disinfectants react with organic matter in water, are associated with an increased risk of cancer, including bladder and colon cancer. The International Agency for Research on Cancer (IARC) has classified chloroform and bromodichloromethane as "possibly carcinogenic to humans" (Group 2B).
- Why here
- These byproducts are formed during the essential disinfection process of drinking water, and exposure occurs through ingestion.
- What would have to be true
- Drinking water containing THMs or HAA5 in excess of established Maximum Contaminant Levels (e.g., 80 μg/L for TTHM in the U.S. and 100 μg/L in the EU for THMs).

Exposure to certain levels of PFAS (per- and polyfluoroalkyl substances) in drinking water is associated with a range of adverse health effects, including reproductive effects (decreased fertility, increased high blood pressure in pregnant women), developmental effects in children (low birth weight, accelerated puberty), increased risk of certain cancers (prostate, kidney, and testicular), reduced immune system ability, interference with natural hormones, and increased cholesterol levels.
- Why here
- PFAS are ubiquitous "forever chemicals" that can contaminate drinking water through various sources, including industrial discharges and firefighting foams.
- What would have to be true
- Ingestion of drinking water contaminated with PFAS. The U.S. EPA has set maximum contaminant levels for specific PFAS compounds (e.g., 4 ng/L for PFOA and PFOS).

Ingesting lead-contaminated drinking water can cause permanent adverse health impacts, particularly on the development of the central nervous system in young children, and long-term harm in adults including increased risk of high blood pressure, cardiovascular problems, and kidney damage.
- Why here
- Lead can leach into drinking water from plumbing systems containing lead pipes, solders, and fittings, especially in older homes.
- What would have to be true
- Any level of lead exposure is considered harmful, with no known safe blood lead concentration, and the EPA's maximum contaminant level goal for lead in drinking water is zero.

Prolonged exposure to high levels of fluoride in drinking water can lead to dental fluorosis (discoloration, spots, or damage to teeth) and crippling skeletal fluorosis (osteosclerosis, calcification of tendons and ligaments, and bone deformities).
- Why here
- Fluoride is naturally present in water or intentionally added for dental health benefits, but excessive intake can occur from naturally rich groundwater or high-fluoride water used in food preparation.
- What would have to be true
- Excessive fluoride intake, particularly above the EPA's maximum contaminant level of 4.0 mg/L, can cause skeletal fluorosis, while levels above the secondary standard of 2.0 mg/L can cause dental fluorosis in children.

Ingesting drinking water containing nitrate in excess of the regulatory standard can cause methemoglobinemia, also known as "blue baby syndrome," a potentially fatal condition in infants under six months old.
- Why here
- Nitrate can contaminate drinking water, particularly groundwater, due to agricultural runoff from fertilizers and animal manure.
- What would have to be true
- Drinking water with nitrate levels above the U.S. EPA standard of 10 mg/L (measured as nitrogen).

Studies have linked drinking water nitrate exposure, even at levels below the regulatory limit, to increased risks of colorectal cancer, bladder cancer, thyroid disease, and birth defects including neural tube defects, as well as adverse pregnancy outcomes like preterm birth and low birth weight. The IARC has concluded that ingested nitrate and nitrite, under conditions that result in endogenous nitrosation, are probably carcinogenic (Group 2A).
- Why here
- Ingestion of nitrate from drinking water can lead to the formation of N-nitroso compounds in the body, which are associated with these health effects.
- What would have to be true
- Ingestion of drinking water with nitrate levels, with associations observed at concentrations below the federal health standard of 10 mg/L, such as at or above 3 mg/L.

Some commentators believe that ingesting microplastics in drinking water could potentially harm reproductive, digestive, and respiratory health, and suggest a link to colon and lung cancer, although this is not scientific consensus.
- Why here
- Microplastics have been detected in both tap and bottled drinking water.
- What would have to be true
- Ingestion of microplastics present in drinking water.
- The other side
- The World Health Organization (WHO) has reported that, based on limited information, microplastics in drinking water do not appear to pose a health risk at current levels, and evidence suggests that microplastic pieces larger than 150 µm pass through the human gastrointestinal tract and are excreted.

The engine has no dossier for water 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.
