Changes in organic matter biodegradatility influencing sulfate reduction in an aquifer contaminated by landfill leachate Changes in organic matter biodegradatility influencing sulfate reduction in an aquifer contaminated by landfill leachate

In situ experiments were conducted to measure sulfate reduction rates and identify rate-limiting factors in a shallow, alluvial aquifer contaminated with municipal landfill leachate. Single-well, push–pull tests conducted in a well adjacent to the landfill with >8 mM dissolved organic carbon (DOC) exhibited a sulfate reduction rate of 3.2 μmol SO4−2 (L sediment)−1 day−1, a value in close...

Partitioning evapotranspiration in sparsely vegetated rangeland using a portable chamber Partitioning evapotranspiration in sparsely vegetated rangeland using a portable chamber

A portable chamber was used to separate evapotranspiration (ET) from a sparse, mixed‐species shrub canopy in southeastern Arizona, United States, into vegetation and soil components. Chamber measurements were made of ET from the five dominant species, and from bare soil, on 3 days during the monsoon season when the soil surface was dry. The chamber measurements were assembled into...
