Spent chlorinated solvents from
an old dry-cleaning facility near Soldotna, Alaska, created a plume
of chloroethenes in the subsurface. USGS scientists are studying the
natural attenuation of the plume using a combination of biological and
geochemical methods. The Kenai River can be seen through the trees in the background

Diffusion
samplers were placed in the bed sediments of the Kenai River,
AK, to monitor the biogeochemistry of a chloroethene plume as it
discharges into the river

USGS scientists studied the natural
attenuation of a chlorinated-solvents plume at an old dry-cleaning
facility near Soldonta, AK. Here ground water is being sampled to assess
redox conditions in the plume

A flow-through chamber is used to measure redox conditions (pH, Eh, temperature, .) in ground
water being pumped from a well in a naturally biodegrading plume of chloroethenes, Soldotna, AK
