Lindane in Drinking Water: Health Risks, Sources, and How to Remove It
Lindane is an organic contaminant that can sometimes be found in drinking water supplies. The Environmental Protection Agency (EPA) regulates this chemical due to health concerns. The EPA has set the Maximum Contaminant Level (MCL) for Lindane at 0.2 μg/L to protect public health.
Health Effects
Consuming water containing Lindane at levels exceeding the safety limit can have negative health effects. Specifically, exposure to this organic compound can cause liver damage. It is also known to cause kidney damage over time.
How Lindane Gets Into Tap Water
Lindane primarily enters the water supply through human activities and agricultural practices. Runoff of insecticide residues can carry the contaminant into local water sources. Additionally, industrial waste can release Lindane into water bodies that feed drinking water systems.
How to Remove Lindane From Your Water
Various water treatment methods are available to remove Lindane from drinking water. Granular activated carbon is an effective treatment technology used for this purpose. Consumers can install certified carbon filtration systems to reduce the levels of this organic contaminant in their water.
Should You Test Your Water?
To determine if Lindane is present in your tap water, you can review your local utility's annual Consumer Confidence Report or use the WaterQ search tool. If you rely on a private well in an area with agricultural or industrial activity, having your water tested by a certified laboratory is recommended. You can also look up your local water system on WaterQ or check the Lindane data page for reported levels in your area.
Frequently Asked Questions
Is Lindane dangerous in drinking water?
Yes, Lindane can cause health issues if consumed in water at levels above the EPA limit of 0.2 μg/L. Exposure to this organic contaminant is linked to liver and kidney damage. It is important to treat water if Lindane is detected.
How does Lindane get into tap water?
Lindane typically enters tap water sources from insecticide residues and industrial waste. These residues run off or discharge into water supplies, contaminating the drinking water source.
How can I remove Lindane from my water?
Lindane can be effectively removed using granular activated carbon treatment systems. Look for certified water filters that utilize this carbon technology for home use.

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
