effects of turbidity, sediment, and polyacrylamide

Effects of turbidity, sediment, and polyacrylamide. Turbidity is a ubiquitous pollutant adversely affecting water quality and aquatic life in waterways globally. Anionic polyacrylamide (PAM) is widely used as an effective chemical flocculent to reduce suspended sediment (SS) and turbidity.

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. The test sites were three North Carolina Department of Transportation construction sites

Recent studies have shown that turbidity in construction site runoff can be greatly reduced by chemical turbidity control. This study evaluated the performance of chitosan-based biopolymer (dual polymer system, DPS) vs. anionic polyacrylamide (PAM) for turbidity reduction and characteristics of flocculated sediments using two soils from North Carolina, USA. The soils were Coastal Plain sand

The seed and mulch effects were highly significant for turbidity and sediment yield for all storms except the first. Although the PAM treatments were not statistically different from the controls, the lowest turbidity and sediment loss on the bare soil plots was with the 10.5 kg [ha.sup.-1] (9.3 lb [ac.sup.-1]) rate of Siltstop 705 (Table 5).

Erosion rates can be 10-100 times those of typical agricultural fields, and many times more than that of adjacent wooded areas. Even with various sediment trapping devices (e.g.,silt fence, sediment basins, etc.), storm water leaving a construction site contains high turbidity levels that can significantly impact nearby streams and lakes.
