Consumer Factsheet on: TOXAPHENE
List of Contaminants
As part of the Drinking Water and Health pages, this fact sheet is part of a larger publication: National Primary Drinking Water Regulations
This is a factsheet about a chemical that may be found in some public or private drinking water
supplies. It may cause health problems if found in amounts greater than the health standard setby
the United States Environmental Protection Agency (EPA).
What is Toxaphene and how is it used?
Toxaphene is an amber, waxy organic solid with a piney odor. Toxaphene was used as an
insecticide for cotton and vegetables, and on livestock and poultry. These uses have been
restricted, and toxaphene is now used only for special needs, mainly in southern states.

Why is Toxaphene being Regulated?
In 1974, Congress passed the Safe Drinking Water Act. This law requires EPA to determine safe
levels of chemicals in drinking water which do or may cause health problems. These
non-enforceable levels, based solely on possible health risks and exposure, are called Maximum
Contaminant Level Goals.
The MCLG for toxaphene has been set at zero because EPA believes this level of protection
would not cause any of the potential health problems described below.
Based on this MCLG, EPA has set an enforceable standard called a Maximum Contaminant Level
(MCL). MCLs are set as close to the MCLGs as possible, considering the ability of public water
systems to detect and remove contaminants using suitable treatment technologies.
The MCL has been set at 3 parts per billion (ppb) because EPA believes, given present technology
and resources, this is the lowest level to which water systems can reasonably be required to
remove this contaminant should it occur in drinking water.
These drinking water standards and the regulations for ensuring these standards are met, are
called National Primary Drinking Water Regulations. All public water supplies must abide by
these regulations.
What are the Health Effects?
Short-term: EPA has found toxaphene to potentially cause the following health effects when
people are exposed to it at levels above the MCL for relatively short periods of time: central
nervous system effects including restlessness, hyperexcitability, tremors, spasms or convulsions.
Long-term: Toxaphene has the potential to cause the following effects from a lifetime exposure at
levels above the MCL: liver and kidney degeneration; central nervous system effects; possible
immune system suppression; cancer.
How much Toxaphene is produced and released to the environment?
Production of toxaphene in 1977 was nearly 40 million pounds. By 1982, when EPA canceled
most of its uses, consumption was reported at 12 million pounds. Toxaphene is released into the
environment primarily from its application as an insecticide for the protection of cotton, mostly in
southern states.
What happens to Toxaphene when it is released to the environment?
Toxaphene is very persistent, remaining in soil for up to 14 years. It is not expected to leach to
groundwater. It will not break down by microbial or other means. Though it strongly binds to
soils and the sediments of water bodies, it may gradually evaporate to the air where it is slowly
broken down by sunlight. Toxaphene has a high potential to accumulate in aquatic life.
How will Toxaphene be Detected in and Removed from My Drinking Water?
The regulation for toxaphene became effective in 1992. Between 1993 and 1995, EPA required
your water supplier to collect water samples every 3 months for one year and analyze them to find
out if toxaphene is present above 1 ppb. If it is present above this level, the system must continue
to monitor this contaminant.
If contaminant levels are found to be consistently above the MCL, your water supplier must take
steps to reduce the amount of toxaphene so that it is consistently below that level. The following
treatment methods have been approved by EPA for removing toxaphene: Granular activated
charcoal.
How will I know if Toxaphene is in my drinking water?
If the levels of toxaphene exceed the MCL, 3 ppb, the system must notify the public via
newspapers, radio, TV and other means. Additional actions, such as providing alternative
drinking water supplies, may be required to prevent serious risks to public health.
Drinking Water Standards:
Mclg: zero Mcl: 3 ppb
Learn more about your drinking water!
EPA strongly encourages people to learn more about their drinking water, and to support local
efforts to protect and upgrade the supply of safe drinking water. Your water bill or telephone
book's government listings are a good starting point.
Your local water supplier can give you a list of the chemicals they test for in your water, as well
as how your water is treated.
Your state Department of Health/Environment is also a valuable source of information.
For help in locating these agencies or for information on drinking water in general, call: EPA's
Safe Drinking Water Hotline: (800) 426-4791.
For additional information on the uses and releases of chemicals in your state, contact the:
Community Right-to-Know Hotline: (800) 424-9346.
