Polyacrylamide (PAM) is a polymer used chemical for a variety of purposes. Non agricultural uses of PAM include waste and potable water treatment, processing and washing of fruits and vegetables, clarification of juices, manufacturing of cosmetics, and paper production. The main agricultural use of PAM is for stabilizing soil and preventing erosion.
Erosion & Sediment Control Technical Bulletin #2 APPLICATION
Standards 1 (soil stabilization) and 19 (stormwater management) of the Virginia Erosion & Sediment Control Regulations (4VAC50-30-40), and in turn, preventing degradation of off site property and water resources. Applicability Anionic PAM is intended for use on areas that contain high amounts of fine silt, clay, or colloidal soils. Anionic PAM
Using Polyacrylamide to Reduce Soil Erosion
There is no indication of any adverse impact on soil, plant or aquatic systems when anionic PAM is used to control soil erosion. Because PAM limits soil erosion, using it can prevent nonpoint source pollutants from leaving the field. Nonpoint source pollutants include the soil and contaminants that can be attached to the soil — nutrients, herbicides and pesticides. Conclusions. Polyacrylamide can control soil erosion that occurs with irrigation.
ANIONIC POLYACRYLAMIDE (PAM) EROSION CONTROL
based on soil properties, slope, and type of erosion targeted. Where reasonably possible, tailwater or runoff containing PAM should be stored for re-use or recycled on other land areas. Use of polyacrylamide in combination with other conservation and Best Management Practices will improve erosion control. Irrigation Induced Erosion Considerations

Factors affecting flocculation performance of synthetic
Flocculation has been used to treat wastewater in sewage and industrial treatment plants for many years, but recently it has been applied to storm water runoff to settle down the solids in runoff. There is a wide range of flocculants available varying in chemistry, ionic charge, molecular weight, branching, and physical form.
What can be done to prevent or clean up acid mine drainage
Diverting water from the mine site to prevent it from running through AMD-forming materials . Disposing mine waste underwater to prevent exposure to oxygen . In addition to the methods listed above, a wide variety of alternative methods have been employed to prevent or treat acid mine drainage.
Land Degradation, Soil Erosion and Soil Conservation | PMF IAS
Land Degradation Soil degradation is the decline in soil quality caused by its improper use, usually for agricultural, pastoral, industrial or urban purposes. Soil degradation is a serious global environmental problem and may be exacerbated by climate change.

In such places, alternative methods like water recycling, groundwater reuse are practiced to ensure adequate supply throughout the year. The potential impacts of EDCs and pharmaceuticals become more prominent especially when municipal wastewater effluent is used for direct or indirect potable reuse.

It may be used with or without chemical precipitation according to the application, and is well suited for tertiary filtration in both sewage and industrial wastewater treatment applications.
Causes and Effects of Soil Pollution on the Environment
The main reason why the soil becomes contaminated is due to the presence of man made waste. The pollution of soil is a common thing these days, and it happens due to the presence of man made elements. Lets have a look at various causes and effects of soil pollution.
Polyacrylamide in Agriculture and Environmental Land
Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation‐induced erosion and enhance infiltration. Its soil stabilizing and flocculating properties improve runoff water quality by reducing sediments, N, dissolved reactive phosphorus (DRP) and total P, chemical oxygen demand (COD), pesticides, weed seeds, and microorganisms in runoff.
