Standard Practice for Obtaining Rainfall Runoff from Unvegetated Rolled and Hydraulic Erosion Control Products (RECPs and HECPs) for Acute Ecotoxicity Testing

Importancia y uso:

5.1 A large number of erosion control product manufacturers produce a variety of RECPs and HECPs that are designed to be applied to any land surface to stabilize soils and prevent erosion. Many of these products are engineered to absorb moisture and remain in place even under extreme rainfall events and are composed of substances that could go into solution with runoff. Based on the characteristics of these products and their intended and actual use in the environment, the most likely scenario through which aquatic organisms would be exposed to these products or their soluble components is through storm water runoff. Further, because such runoff events typically last for minutes to hours rather than days, use of acute (48 h) toxicity testing methodology is appropriate to model expected environment exposures.

Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it and the suitability of the equipment and facility used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some, but not all, of those factors.
