mixed with water and sprayed onto the soil surface in slurry form to provide a layer of temporary protection from wind and water erosion. Suitable Applications.
1 Temporary Best Management Practices 1.1 Introduction The two most basic categories of temporary control methods for construction-generated pollution are erosion and sediment controls. Erosion controls are used to prevent soil on the construction site from being mobilized and transported by stormwater runoff.
BMP C126 Polyacrylamide PAM for Soil Erosion Protection Purpose Polyacrylamide PAM is used on construction sites to prevent soil erosion. Applying PAM to bare soil in advance of a rain event significantly reduces erosion and controls sediment in two ways.
Aug 03 2021 Using Polyacrylamide PAM to Reduce Erosion on Construction Sites SoilFacts. Introduction Skip to Introduction. Sediment and turbidity have the widest impact on water quality of any pollutants. Runoff from sites where bare soil is exposed such as construction sites or tilled farm fields often carries high sediment loads into receiving water.

anionic polyacrylamide mixture near waters of the state is recommended. F. Applying an additive mixture to soil may provide benefits of improved water quality infiltration soil fertility and visibility by reducing wind and water erosion. s. G. For erosion control the additive may be applied upgradient of lands planted in food crops.
Because sediment is the major potential pollutant and because sediment is a product of soil erosion the major emphasis of this BMP manual will be on those practices designed to reduce or prevent erosion. Practices that keep the soil in place also aid in reducing the risk of other pollutants reaching surface waters wetlands and groundwater.
Soil erosion is a natural process occurring over geological time typically at rates of 0.1 - 5 t.ha-1.y-1 Kirkby 2001. Erosion literature commonly identifies acceptable rates of soil erosion Sparovek and Schung 2001 but these rates usually exceed the rates that can be balanced by weathering of new soil from parent materials.

SECTION 8 - SELECTION OF BMP FOR EROSION AND SEDIMENDATION CONTROL June 2011 8-3 Specific measures and BMPs are published in many manuals and standards which describe criteria and specifications in detail. Many of the BMPs most commonly used in Alberta are presented in Appendix C.

and maintenance of BMPs. The inclusion of detailed design information has purposely been kept to a minimum. For more detailed information The Manual for Erosion and Sedi-ment Control in Georgia should be consulted. BMPs are vegetative measures and structural practices that control the erosion of soil and the resulting sedimentation. The law.
Examples of Erosion Prevention BMPs are but are not limited to surface roughening temporary seeding erosion control blankets turf reinforcement mats sodding riprap outlet protection dust control and polyacrylamide PAM. Information on the design and proper use of Erosion Prevention BMPs can be located in the SC DHECs BMP Handbook.
PAM is a cost effective erosion amp; sediment control water quality and water quantity BMP PAM performance and safety is based upon specific soil and PAM product characteristics PAM is not a stand alone BMP but works best when implemented to enhance performance of a BMP treatment train ACF Environmental Inc.

prevention of soil erosion capture of water-borne sediment that has been unavoidably released from exposed soils and protection of water quality from on-site pollutant sources are all readily achievable when the proper Best Management Practices BMPs are planned installed and properly maintained.
For soil erosion the check furrows lost 322 lbac of sediment off of the field in the runoff water during a single irrigation. Furrows irrigated with granular PAM lost 7 lbac of sediment off of the field while those irrigated with the liquid solution of PAM lost 104 lbac. Remember though the granular PAM was applied at a rate double the liquid.
