We surveyed the insect fauna associated with Urophora cardui L. (Diptera: Tephritidae) galls on Canada thistle, Cirsium arvense L. (Asterales, Asteraceae), in parts of the northern Great Plains, U.S., by field-collecting galls and rearing or dissecti

In 1990, the town of Hopkinton, Mass., instituted a polyphosphate sequestrant feed in two of its five wells to address colored water complaints caused by source water iron and manganese. Failure to meet the Lead and Copper Rule (LCR) action levels an

Iron release from corroded iron pipes is the principal cause of "colored water" problems in drinking water distribution systems. The corrosion scales present in corroded iron pipes restrict the flow of water, and can also deteriorate the water qualit

One goal of drinking water treatment is to minimize iron uptake from distribution systems in which old, corroded iron and steel pipes are used. This research evaluated the effects of changes in pH and alkalinity and the use of orthophosphates to mini

To assess the interactions between pipe materials, organic carbon levels, and disinfectants, studies using annular reactors with ductile-iron, polyvinyl chloride (PVC), epoxy, and cement-lined coupons were carried out in the laboratory and at four fi

Corrosion scales play an important role in modifying water quality in drinking water distribution systems. The corrosion scales from old iron/steel pipes were analyzed for their structure and composition. Scales were studied both before and after dry

Aeration is a useful drinking water treatment process. Aeration has been used to remove hydrogen sulfide, methane, radon, iron, manganese, and volatile organic contaminants from drinking water. Aeration also removes carbon dioxide, which directly aff

The performance of point-of-entry granular activated carbon (GAC) and diffused-bubble and bubble-plate aeration systems was evaluated for one year with respect to radon removal efficiency, potential problems, and economics. The radon removal efficien
