Di(2-ethylhexyl) adipate in Drinking Water: Health Risks, Sources, and How to Remove It
Di(2-ethylhexyl) adipate is an organic contaminant that can occasionally be found in drinking water. The U.S. Environmental Protection Agency (EPA) has set a Maximum Contaminant Level (MCL) of 400 μg/L for this chemical. Monitoring public water supplies ensures that concentrations of this organic compound remain within safe regulatory limits.
Health Effects
Exposure to Di(2-ethylhexyl) adipate in drinking water can lead to several potential health concerns if levels exceed the standard over time. These effects include weight loss and liver problems. There is also a possibility of experiencing reproductive difficulties.
How Di(2-ethylhexyl) adipate Gets Into Tap Water
This organic chemical can enter water supplies through industrial releases and materials used in infrastructure. A primary source of entry is leaching from PVC pipes. Additionally, discharges from chemical factories can introduce the contaminant into source waters.
How to Remove Di(2-ethylhexyl) adipate From Your Water
Water systems can utilize specific treatment technologies to lower the concentration of this compound. Granular activated carbon is a common treatment method that is effective for its removal. Packed tower aeration is another standard treatment method used to address this contaminant.
Should You Test Your Water?
You can check your local water utility's annual consumer confidence report or search the WaterQ database to see if this contaminant is monitored in your area. If you use a private well and suspect nearby industrial activity or have PVC piping, periodic testing may be beneficial. You can also look up your local water system on WaterQ or check the Di(2-ethylhexyl) adipate data page for reported levels in your area.
Frequently Asked Questions
Is Di(2-ethylhexyl) adipate dangerous in drinking water?
Consuming water containing Di(2-ethylhexyl) adipate above the safe limit over a long period can lead to health issues. These potential effects include weight loss and liver problems. Exposure might also lead to possible reproductive difficulties.
How does Di(2-ethylhexyl) adipate get into tap water?
It primarily gets into tap water by leaching from PVC pipes or through discharge from chemical factories.
How can I remove Di(2-ethylhexyl) adipate from my water?
Effective removal methods include the use of granular activated carbon or packed tower aeration systems.

What actually removes pesticides and herbicides
These are organic molecules, and granular activated carbon adsorbs them well — it is EPA's designated best available technology for nearly the whole class. An NSF/ANSI 53 filter is sufficient; reverse osmosis is not required. Worth knowing about timing: pesticide levels in surface-water systems spike for a few weeks after spring application, and an annual average in your utility report can hide a much higher seasonal peak.
Works
- Carbon certified for lead (NSF 53)The cheapest thing that genuinely removes lead, cysts and many VOCs.
- Reverse osmosis (NSF 58)The broadest removal available at home: arsenic, nitrate, fluoride, PFAS, TDS.
Will not fix this
- Ion-exchange water softener
- UV disinfection (NSF 55)
- Ion-exchange pitcher
