Groundwater Quality In Kentucky: Iron, R. Stephen Fisher, Bart Davidson
Groundwater Quality In Kentucky: Iron, R. Stephen Fisher, Bart Davidson
Information Circular--KGS
Iron is one of the most abundant elements in rocks and soils, and one of the most common problems in groundwater supplies. Rainwater seeping through soils and bedrock dissolves iron and carries it to wells and springs. In deep groundwater systems that lack oxygen, iron occurs as dissolved ferrous ion and the water is clear. Under oxidizing conditions such as in shallow groundwater systems or where the water is exposed to air at a tap or faucet, however, iron converts to a ferric form when it combines with oxygen to form reddish-brown rust particles. In addition to natural sources, elevated …

Groundwater Quality In Kentucky: Manganese, R. Stephen Fisher, Bart Davidson
Information Circular--KGS
Manganese is a common constituent of Kentucky rocks and soils and, along with iron is one of the most widespread causes of problems in groundwater supplies. Rainwater seeping through soils and bedrock dissolves manganese and carries it in the groundwater system to wells and springs. In deep, slow-moving systems that lack oxygen, manganese remains in solution. Under oxidizing conditions, however, such as in shallow groundwater systems or where the water is exposed to air, manganese combines with oxygen to form black particles that can clog plumbing fixtures and stain containers and clothing.

Groundwater Quality In Kentucky: 2,4-D, Bart Davidson, R. Stephen Fisher
Information Circular--KGS
2,4-dichlorophenoxyacetic acid, commonly known as 2,4-D, is an herbicide used for selective control of broadleaf and grassy weeds in crops such as corn and wheat, along roadways and rights-of-way, and on pasture and rangeland. 2,4-D is the most widely used herbicide in the world, and the third most widely used in North America after metolachlor and atrazine. 2,4-D is a synthetic, organic, white to yellow, odorless, crystalline powder that dissolves readily in water. It is widely used today primarily because of its low cost.
Groundwater Quality In Kentucky: Atrazine, Bart Davidson, R. Stephen Fisher
Groundwater Quality In Kentucky: Atrazine, Bart Davidson, R. Stephen Fisher
Information Circular--KGS
Atrazine is an organic herbicide used for selective control of broadleaf and grassy weeds in crops such as corn, soybeans, sorghum, sugarcane, macadamia nuts, pineapples, pine trees, grasslands, and roses. Atrazine does not harm the crops, which can absorb and metabolize the herbicide, thereby removing the toxins. It controls targeted plants by inhibiting photosynthesis (Wilkes University Center for Environmental Quality, 2003). Atrazine is a white, odorless, crystalline powder that dissolves readily in water and does not occur naturally. It is widely used because of its low cost and ability to reduce crop losses from weed interference.
