Difficulty With Accurate Testing For BOD In Industrial Stormwater Runoff
Biochemical oxygen demand (BOD) is a measure of the amount of dissolved oxygen used by microorganisms to break down organic material in a sample of water. Because BOD is not one specific pollutant, it can be difficult to characterize the nature of BOD, identify the source in stormwater runoff, and select the appropriate treatment approach to reduce BOD in stormwater runoff and discharge. The most effective way to minimize BOD concentrations in stormwater discharges will be to minimize the exposure of stormwater to materials that are a source of BOD.
What is PFAS?
PFOA (perfluorooctanic acid) and PFOS (perflurooctane sulfonate) are organic synthetic chemicals that have been used in manufacturing a multitude of industrial and consumer-based products including coatings, carpeting, and fire-fighting foams. Over several decades, they have contaminated the environment, specifically our drinking water sources, causing significant health concerns that recently prompted the EPA to take action.
What is Activated Carbon?
Although the term granular activated carbon is used generically, it can refer to dozens of similar – but not identical- adsorbents. Depending on raw material, method and degree of activation and other factors, activated carbons can perform differently in various applications.
