  • Data Requirements for Soil, Sediment, and Sludge

    Site soil conditions frequently limit the selection of a treatment process. Process-limiting characteristics such as pH or moisture content may sometimes be adjusted. In other cases, a treatment technology may be eliminated based upon the soil classification (e.g., particle-size distribution) or other soil characteristics. Soils are inherently variable in their physical and chemical ...

  • Connections: Understanding Urban Soil Lead

    There is no such thing as unleaded when talking about soils in urban areas. If a car had ever been driven near or paint had been applied to a home built on the soil prior to 1975, that soil will have measurable concentrations of lead. It can be detected in soils at the subparts per million range. Lead can cause developmental delays and reduced mental capacity. In short, lead is bad. But does a ...
