Polyacrylamide use for erosion and turbidity control on

ABSTRACT: Streams and lakes adjacent to construction sites are often heavily impaired by sediment and turbidity coming from areas of exposed soil. A study was conducted to determine if the application of polyacrylamide (PAM) can reduce erosion and runoff turbidity on moderate to steep slopes at construction sites.

Using Polyacrylamide (PAM) to Reduce Erosion on Construction

The chemical polyacrylamide (PAM) is well suited for erosion control enhancement, and its use is described below. Characteristics of PAM PAM is a term describing a wide variety of chemicals based on the acrylamide and acrylate units.

Polyacrylamide Use for Erosion and Turbidity Control on

Polyacrylamide applied with seed/mulch produced slight reductions in turbidity and sediment loss in early rain events. At the higher rate, PAM applied directly on a more moderate, 4:1 fill slope decreased sediment loss and turbidity in the first few rain events following application compared to bare soil, with decreases diminishing over time.

A Guide to Using Polyacrylamide (PAM) Polymers for Control of

The main agricultural use of PAM is for stabilizing soil and preventing erosion. PAM is also used for dust control on unpaved roads. Various forms of PAM exist, but the type used for erosion control is a large, negatively (anionic) charged molecule (12-15 megagrams per mole) that is water soluble.

granular and dissolved polyacrylamide effects on erosion

Granular and Dissolved Polyacrylamide Effects on Erosion

Polyacrylamide (PAM) has been demonstrated to reduce erosion under many conditions, but less is known about the effects of its application method on erosion and concentrations in the runoff water. A rainfall simulation study was conducted to evaluate the performance of an excelsior erosion control blanket (cover) and two PAM application methods.

trade-off between runoff and sediments from treated erosion

Trade-off between runoff and sediments from treated erosion

In recent years, the use of anionic polyacrylamide (PAM) as an erosion control measure has gained increased attention (Shoemaker, 2009, Entry et al., 2013). Knowledge about the content of PAM and acrylamide (AMD) lost in runoff and sediment is, therefore, essential for the proper management of agricultural and natural resources.

Chemical Treatment to Reduce Turbidity in Pumped Construction

Polyacrylamide (PAM) is a common type of polymeric flocculant that has been successful in reducing sediment erosion and turbidity (Sojka et al. 2007). The application of granular PAM to fiber check dams in ditches has been found to be effective in reducing turbidity by more than 90% relative to a standard rock check system with no PAM ...
