1,2-Dichloroethane in Drinking Water: Health Risks, Sources, and How to Remove It
1,2-Dichloroethane is a synthetic organic chemical that is regulated as a contaminant in drinking water. It belongs to the organic category of water contaminants and has an Environmental Protection Agency (EPA) Maximum Contaminant Level (MCL) of 5 μg/L. Exposure to levels above this standard can lead to potential health concerns.
Health Effects
Ingesting water contaminated with 1,2-Dichloroethane presents a potential health hazard over time. Specifically, exposure to this organic compound is associated with an increased risk of cancer. Ensuring water levels remain below regulatory limits helps mitigate these long-term health risks.
How 1,2-Dichloroethane Gets Into Tap Water
This contaminant typically enters drinking water supplies through industrial discharge. Specifically, releases from chemical factories can introduce this chemical into local water sources. Monitoring nearby water bodies is common practice for areas surrounding these industrial facilities.
How to Remove 1,2-Dichloroethane From Your Water
Effective treatment methods for removing this contaminant from drinking water include granular activated carbon and packed tower aeration. Treatment systems using granular activated carbon are commonly used to filter out such organic compounds. These methods help ensure municipal or private water supplies meet safe standards.
Should You Test Your Water?
To determine if this contaminant is present, you can review your local water utility's annual Consumer Confidence Report or check the WaterQ database. Private well owners should consider periodic laboratory testing for organic compounds if they live near chemical factories or industrial areas. You can also look up your local water system on WaterQ or check the 1,2-Dichloroethane data page for reported levels in your area.
Frequently Asked Questions
Is 1,2-Dichloroethane dangerous in drinking water?
Yes, 1,2-Dichloroethane poses a long-term health risk when present in drinking water. Exposure to this chemical in water supplies is linked to an increased risk of cancer. Keeping levels below the maximum limit of 5 μg/L is important for safety.
How does 1,2-Dichloroethane get into tap water?
This chemical gets into water supplies through industrial discharge, particularly from chemical factories.
How can I remove 1,2-Dichloroethane from my water?
It can be removed from drinking water using granular activated carbon or packed tower aeration.

What actually removes vocs (benzene, tce, pce and related solvents)
Volatile organic compounds are the case where activated carbon genuinely shines — EPA lists granular activated carbon as the best available technology for most of them. Look for an NSF/ANSI 53 filter with a VOC reduction claim rather than a plain taste-and-odor cartridge. Because VOCs evaporate readily, they also enter the air during hot showers, so a whole-house carbon filter is worth considering when levels are high, not just a filter at the kitchen tap.
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.
- Catalytic carbonRequired for chloramine. Standard carbon barely touches it.
Will not fix this
- Ion-exchange water softener
- UV disinfection (NSF 55)
- Ion-exchange pitcher
Test before you buy.VOCs (benzene, TCE, PCE and related solvents) can't be seen, tasted or smelled, and the right hardware depends on the concentration you actually have. A certified lab test costs a fraction of the wrong filtration system. Start with your local water quality report, and get a mail-in lab test if you're on a private well.

|---|---|---|---|---|
| Aquasana AQ-5200 Under-SinkUnder-sink | NSF/ANSI 42, 53, 401 and P473 certified.Catch:Carbon, not RO — no meaningful fluoride, nitrate or arsenic reduction. | $110–160 | $80–120 | Check price |
| SpringWell CF1 Whole-House CarbonWhole house | Catalytic carbon media, which is the grade required to reduce chloramine.Catch:Whole-house carbon protects showers and appliances but is not a substitute for a point-of-use lead or PFAS filter at the tap. | $900–1,400 | $0–100 | Check price |
| APEC ROES-50 EssenceUnder-sink | Built with WQA-certified components to NSF/ANSI 58.Catch:Needs an under-sink drain connection and a spare hole for the dedicated faucet. Strips minerals — some people dislike the flat taste. | $180–240 | $50–80 | Check price |
| Brita Elite Pitcher FilterPitcher | NSF/ANSI 42 and 53 certified, including a lead reduction claim.Catch:No fluoride, nitrate or arsenic reduction. Not PFAS-rated. | $25–40 | $50–70 | Check price |
Certification listings change. Before buying, confirm the current listing for the exact model in the NSF certified products database — a manufacturer's marketing page is not a certification.
