Methoxychlor is a colorless organic solid with a slightly fruity odor. It is an insecticide preferred to DDT for use on animals, in animal feed, and on DDT-sensitive crops such as squash, melons, etc. Since methoxychlor is more unstable than DDT, it has less residual effect. It has been used extensively in Canada for the control of biting flies, and is also effective against mosquitoes and houseflies. The major source of methoxychlor in drinking water is runoff/leaching from insecticide used on cattle, lumber, gardens.
Some people who drink water containing methoxychlor well in excess of the maximum contaminant level (MCL) for many years could experience reproductive difficulties.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Methoxychlor levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Methoxychlor levels were detected in your water sample but do not exceed the maximum contaminant level.
