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.
