A series of discrete water-quality samples were collected in the lower Stillaguamish River Basin near the city of Arlington, Washington, through a partnership with the Stillaguamish Tribe of Indians. These samples included surface waters of the Stillaguamish River, adjacent tributary streams, and paired inflow and outflow sampling at three wastewater treatment plants in the lower river basin. Chemical analysis of these samples focused on chemicals of emerging concern, including wastewater compounds, human-health pharmaceuticals, steroidal hormones, and halogenated organic compounds on solids and sediment. This report presents the methods used and data results from the chemical analysis of these samples

Emerging contaminants are a group of chemical compounds that generally include pharmaceuticals, personal-care products, surfactants, industrial and household chemicals, and food additives. Their presence in the environment is typically associated with discharges from wastewater treatment-plants (WWTP), on-site septic systems, and some animal production operations. They are of particular interest...
