Monsoon-Rain Flow in an Ephemeral Channel near Sierra Vista, Arizona

As part of the assessment of the binational San Pedro aquifer, the effects of urbanization on runoff in ephemeral streams was studied. Ephemeral streams are those that flow in response to precipitation. Runoff in tributaries to the San Pedro River is important in understanding the water budget of the river. In addition, in arid watersheds such as the San Pedro, flow in

Slicing a core of lake sediment

Sediment cores from lakes and reservoirs can be used to reconstruct contaminant histories in watersheds. Sediment-core analyses indicate that concentrations of PAHs in many U.S. urban lakes are increasing, and multiple lines of evidence indicate that the source of the PAHs in coal-tar-based pavement sealants.

Driveway with black sealcoat

Many homeowners have their driveway sealcoat to protect and beautify the underlying asphalt. Coal-tar-based sealcoat, predominantly used east of the Continental Divide, is a potent source of polycyclic aromatic hydrocarbons (PAHs). Read more about coal-tar-based sealcoat and PAHs here.

Dust swept from coal-tar-sealed parking lot pavement

Dust swept from parking lots sealed with coal-tar-based sealant contains concentrations of polycyclic aromatic hydrocarbons (PAHs) about 1,000 higher than dust from parking lots with other surface types (concrete, unsealed asphalt, asphalt-based sealcoat). Coal-tar-based sealcoat is predominantly used east of the Continental Divide. Read more about coal-tar-based sealcoat
