Di(2-ethylhexyl) phthalate is a pollutant from rubber and industrial chemical factories and a leachate from PVC pipes; it is classified by EPA as a probable human carcinogen. [read more]
The Most Polluted Communities in Utah
7 water utilities reported detecting Di(2-ethylhexyl) phthalate in tap water since 2004, according to EWG's analysis of water quality data supplied by state water agencies
Ranked by highest average Di(2-ethylhexyl) phthalate level

Health Based Limits for Di(2-ethylhexyl) phthalate
| Standard | Description | Level |
|---|---|---|
| Maximum Contaminant Limit Goal (MCLG) | A non-enforceable health goal that is set at a level at which no known or anticipated adverse effect on the health of persons occurs and which allows an adequate margin of safety. Source: U.S. Environmental Protection Agency. | 0 ppb |
| One in one million (10-6) Cancer Risk | The concentration of a chemical in drinking water corresponding to an excess estimated lifetime cancer risk of 1 in 1,000,000. Source: U.S. Environmental Protection Agency. | 3 ppb |
| Maximum Contaminant Limit (MCL) | The enforceable standard which defines the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to health-based limits (Maximum Contaminant Level Goals, or MCLGs) as feasible using the best available analytical and treatment technologies and taking cost into consideration. Source: U.S. Environmental Protection Agency. | 6 ppb |
| California Public Health Goals | Defined by the State of California Office of Environmental Health Hazard Assessment (OEHHA) as the level of contaminant that is allowed in drinking water. For acutely toxic substances, levels are set at which scientific evidence indicates that no known or anticipated adverse effects on health will occur, plus an adequate margin-of safety. PHGs for carcinogens or other substances which can cause chronic disease shall be based solely on health effects without regard to cost impacts and shall be set at levels which OEHHA has determined do not pose any significant risk to health. | 12 ppb |
| One in ten thousand (10-4) Cancer Risk | The concentration of a chemical in drinking water corresponding to an excess estimated lifetime cancer risk of 1 in 10,000. Source: U.S. Environmental Protection Agency. | 300 ppb |
| Drinking Water Equivalent Level | A lifetime exposure concentration protective of adverse, noncarcinogenic health effects, that assumes all of the exposure to a contaminant is from drinking water. Source: U.S. Environmental Protection Agency. | 700 ppb |
