Environmental Protection Agency Region IV Perspective on SOD,
Abstract
Descriptive studies of sediment oxygen demand (SOD) are found in the literature dating back to the early 1900's. These assessments were often laboratory studies. Later, the techniques for in situ measurements were published in the 1950's (Davis and Davis 1986). Since then, the basic approaches to measuring SOD have remained unchanged and still involve laboratory treatment of sediments removed from the natural setting or in situ measurements using chamber devices. Among these two approaches, a variety of methods are found as indicated in the proceedings of a national/international SOD workshop conducted in 1986 (Institute of National Resources 1986). The purpose of this paper is not to debate the pros and cons of these methods but rather to identify some research objectives which in my judgment would significantly add to our ability to provide accurate and representative SOD rates for environmental decisions. To start my discussion, I'll provide you with a brief review of EPA Region IV's approach to measuring SOD. Drawing from my experience in Region IV, which spans 20 years, I'll attempt to identify some salient concerns I have with the present approach to SOD measurements.
