Contaminants of Emerging Concern in the Environment
Waste samples being collected from an onsite wastewater system
for analysis of emerging contaminants. A strict protocol was followed to prevent contamination of the samples (Photo courtesy of the Colorado School of Mines).
Filling sample bottles with liquid collected from a municipal holding pond in Colorado as part of the Source Characterization Study
for Emerging Contaminants Project. The multiple sample bottles are required for the analysis of different classes of emerging contaminant compounds.
A fish tank used to expose fish to wastewater effluent in a controlled laboratory experiment
for the Emerging Contaminants Investigation. Relatively little is known about the possibility of endocrine disrupting effects on fish when exposed to chronic low-level doses of organic wastewater compounds found in effluent-dominated streams.
View of the base of a soil column used to study the transport of emerging contaminants through soil
. Effluent that traveled through the soil column was collected at the base of the column. The sensor inserted into the column on the right side monitored the temperature of the effluent.
Pressurized filtration unit used to filter liquid waste samples from the Source Characterization Study
for Emerging Contaminants Project. Filtered samples were analyzed for a suite of human pharmaceuticals and household and industrial compounds.
