ASTM International’s stormwater control measures committee (E64) has developed a new standard on the characteristics of sediments used in laboratory performance testing of stormwater treatment devices.
The new standard, soon to be published as E3317, describes the minerology, specific gravity, and particle size distributions (PSDs) of silica-based sediments used in the testing of these devices. According to ASTM International member Jay Holtz, using a standard sediment during performance testing helps provide consistent and comparable results.
“Standardized performance results for stormwater treatment devices will allow manufacturers to more accurately assess improvements to technologies, allow regulatory bodies to determine which systems best meet their performance criteria, and ultimately will help provide cleaner stormwater runoff,” says Holtz.
This effort directly relates to the United Nations Sustainable Development Goal #6 on clean water and sanitation.
