Pollutant Sources
vehicles, batteries, paints, dyes, stormwater
Heavy Metals: Pb, Hg, Cu, and others
runoff, spills, pipes.
Organic Compounds:
Burning of petroleum, coal, oil spills, leaking
Polycyclic aromatic hydrocarbons (PAHs) underground fuel tanks, creosote, asphalt.

care products. Many of these compounds are
in wastewater from sewage treatment plants.
PBDEs are added to a wide range of textiles
and plastics as a flame retardant. They easily
Polybrominated diphenyl ethers (PBDEs) leach from these materials and have been
found throughout the environment and in
human breast milk.
Puget Sound Basin: NAWQA analysis
The USGS sampled waters in the Puget Sound Basin between 1996 and 1998. (Ebbert,
Embrey et al. 2000) reported that 26 of 47 analyzed pesticides were detected. A total of
74 manmade organic chemicals were detected in streams and rivers, with different
mixtures of chemicals linked to agricultural and urban settings. NAWQA results
reported that the herbicides atrazine, prometon, simazine and tebuthiuron were the most
frequently detected herbicides in surface and ground water (Bortleson and Ebbert 2000).
Herbicides were the most common type of pesticide found in an agricultural stream
(Fishtrap Creek) and the only type of pesticide found in shallow ground water underlying
agricultural land (Bortleson and Ebbert 2000). The most commonly detected VOC in the
agricultural land use study area was associated with the application of fumigants to soils
prior to planting (Bortleson and Ebbert 2000). One or more fumigant-related compound
(1,2-dichloropropane, 1,2,2-trichloropropane, and 1,2,3-trichloropropane) were detected
in over half of the samples. Insecticides, in addition to herbicides, were detected
frequently in urban streams (Bortleson and Ebbert 2000). Sampled urban streams
showed the highest detection rate for the three insecticides: carbaryl, diazinon, and
malathion. Carbaryl was detected at over 60% of urban sample sites (Ebbert, Embrey et
al. 2000). The insecticide diazinon was also frequently detected in urban streams at
