  • 2,4,5-TP (Silvex)

    GENERAL INFORMATION 2,4,5-TP is a white organic powder with little odor. Until Silvex was banned in 1985, the greatest use of 2,4,5-TP was as a post emergence herbicide for control of woody plants and broadleaf herbaceous weeds in rice and bluegrass turf, in sugarcane, in rangeland improvement programs, and on lawns. Aquatic uses included control of weeds in ditches and riverbanks, on floodways, along canals, reservoirs, streams, and along southern waterways. The major source of 2,4,5-TP in drinking water is residue of the banned herbicide.

  • Toxaphene

    GENERAL INFORMATION

  • 2,4-D (2,4-Dichlorophenoxyacetic Acid)

    GENERAL INFORMATION 2,4-D is a colorless, odorless powder. 2,4-D is used as a herbicide for the control of broad-leaf weeds in agriculture, and for control of woody plants along roadsides, railways, and utilities rights of way. The major source of 2,4-D in drinking water is runoff from herbicide used on row crops. HEALTH EFFECTS Some people who drink water containing the weed killer 2,4-D well in excess of the MCL over many years could experience problems with their kidneys, liver, or adrenal glands.

  • Atrazine

    GENERAL INFORMATION Atrazine is a white, crystalline solid organic compound. Atrazine is a widely used herbicide for control of broadleaf and grassy weeds. Effective in 1993, its uses were greatly restricted. The major source of atrazine in drinking water is runoff from herbicide used on row crops. HEALTH EFFECTS Some people who drink water containing atrazine well in excess of the maximum contaminant level (MCL) for many years could experience problems with their cardiovascular system or reproductive difficulties.

  • Carbofuran

    GENERAL INFORMATION

  • Dalapon

    GENERAL INFORMATION Dalapon is a colorless liquid with an acrid odor sold as sodium or magnesium salt. Dalapon is an herbicide used to control grasses in a wide variety of crops, including fruit trees, beans, coffee, corn, cotton and peas. It is also registered for use in a number of non-crop applications such as lawns, drainage ditches, along railroad tracks, and in industrial areas. The major source of dalapon in drinking water is runoff from herbicide used on rights of way.

  • Chlordane

    GENERAL INFORMATION Chlordane, a synthetic organic chemical, is a viscous liquid, colorless to amber, with a slight chlorine-like aromatic odor. Chlordane was used in the past to kill a variety of insects. The only commercial use of chlordane products still permitted is for fire ant control in power transformers. Chlordane has been released into the environment primarily from its application as an insecticide. Chlordane may persist for long periods of time in air, soil and water.

  • Dibromochloropropane

    GENERAL INFORMATION 1,2-Dibromo-3-chloropropane, or DBCP, is a dense yellow organic liquid with a pungent odor. It is used primarily as an unclassified nematocide for soil fumigation of cucumbers, summer squash, cabbage, cauliflower, carrots, snap beans, okra, aster, shasta daisy, lawn grasses and ornamental shrubs. The major source of 1,2-dibromo-3-chloropropane in drinking water is runoff/leaching from soil fumigant used on soybeans, cotton, pineapples and orchards.

  • Dinoseb

    GENERAL INFORMATION Dinoseb is an organic solid -- yellowish crystals with a pungent odor. Its greatest use is as a contact herbicide for post-emergence weed control in cereals, undersown cereals, seedling lucerne and peas. Dinoseb is also used as a corn enhancer and an insecticide and miticide. The major source of dinoseb in drinking water is runoff from herbicide used on soybeans and vegetables.

  • Diquat

    GENERAL INFORMATION Diquat is an organic solid of colorless or yellow crystals. A water solution is dark red-brown. Diquat is a herbicide that has been used extensively in the United States since the late 1950s to control both crop and aquatic weeds. It is used on potatoes; as an aid in harvesting cotton, rapeseed and other oil seed crops; to wilt and dry out silage, standing hay, etc., for storage; a plant growth regulator and sugar cane-flowering suppressant. The major source of diquat in drinking water is runoff from herbicide use.

  • Endothall

    GENERAL INFORMATION Endothall is an organic solid of white odorless crystals. Endothall is used as a defoliant for a wide range of crops and as a herbicide for both terrestrial and aquatic weeds. It is used as a desiccant on lucerne and on potato, for the defoliation of cotton, to control aquatic weeds and as an aquatic algicide growth regulator. It has been used for sugar beets, turf, hops sucker suppression; alfalfa, clover desiccants; potato vine killers. The major source of endothall in drinking water is runoff from herbicide use.

  • Endrin

    GENERAL INFORMATION Endrin is an organic solid of odorless white crystals. Endrin is an insecticide which has been used mainly on field crops such as cotton, maize, sugarcane, rice, cereals, ornamentals, and other crops. It has also been used for grasshoppers in non-cropland and to control voles and mice in orchards. Once widely used in the United States, most uses were cancelled in 1980. The major source of endrin in drinking water is residue of banned insecticide.

  • Glyphosate (aka Roundup©)

    GENERAL INFORMATION Glyphosate is an organic solid of odorless white crystals. Glyphosate is a non-selective herbicide used on many food and non-food crops as well as non-crop areas such as roadsides. When applied at lower rates, it serves as a plant growth regulator. The most common uses include control of broadleaf weeds and grasses in: hay/pasture, soybeans, field corn; ornamentals, lawns, turf, forest plantings, greenhouses, rights-of-way. The major source of glyphosate in drinking water is runoff from herbicide use.

  • Heptachlor

    GENERAL INFORMATION

  • Lindane

    GENERAL INFORMATION Lindane is a white crystalline organic solid. Most uses being restricted in 1983, lindane is currently used primarily for treating wood-inhabiting beetles and seeds. It is also used as a dip for fleas and lice on pets, and livestock, for soil treatment, on the foliage of fruit and nut trees, vegetables, timber, ornamentals and for wood protection. The major source of lindane in drinking water is runoff/leaching from insecticide used on cattle, lumber, gardens.

  • Methoxychlor

    GENERAL INFORMATION 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.
