Book Description
Jessica Martin is not a nice girl. As Prom Queen and Captain of the cheer squad, she'd ruled her school mercilessly, looking down her nose at everyone she deemed unworthy. The most unworthy of them all? The "freak," Manson Reed: her favorite victim. But a lot changes after high school. A freak like him never should have ended up at the same Halloween party as her. He never should have been able to beat her at a game of Drink or Dare. He never should have been able to humiliate her in front of everyone. Losing the game means taking the dare: a dare to serve Manson for the entire night as his slave. It's a dare that Jessica's pride - and curiosity - won't allow her to refuse. What ensues is a dark game of pleasure and pain, fear and desire. Is it only a game? Only revenge? Only a dare? Or is it something more? The Dare is an 18+ erotic romance novella and a prequel to the Losers Duet. Reader discretion is strongly advised. This book contains graphic sexual scenes, intense scenes of BDSM, and strong language. A full content note can be found in the front matter of the book.

Book Description
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use of other waste-management practices. As a result, summer dissolved-oxygen levels have increased, salmon runs have returned, and the overall effort is widely regarded as a singular water-quality success. To document the improved dissolved-oxygen regimen, the U.S. Geological Survey conducted intensive studies of the Willamette during the summer low-flow seasons of 1973 and 1974. During each summer the mean daily dissolved-oxygen levels were found to be higher than 5 milligrams per liter throughout the river. Because of the basinwide secondary treatment, carbonaceous deoxygenation rates were low. In addition, almost half of the biochemical oxygen demand entering the Willamette was from diffuse (nonpoint) sources rather than outfalls. These results indicated that point-source biochemical oxygen demand was no longer the primary cause of dissolved-oxygen depletion. Instead, the major causes of deoxygenation were nitrification in a shallow ' surface active ' reach below Salem and an anomalous oxygen demand (believed to be primarily of benthal origin) in Portland Harbor.

Book Description
The U.S. Geological Survey (USGS) established the National Water Quality Assesment (NAWQA) program in 1985 to assess water quality conditions and trends in representative river basins and aquifers across the United States. With this report, the NRC's Water Science and Technology Board has provided advice to USGS regarding NAWQA five separate times as the program evolved from an unfunded concept to a mature and nationally-recognized program in 2002. This report assesses the program's development and representative accomplishments to date and makes recommendations on opportunities to improve NAWQA as it begins its second decade of nationwide monitoring.

Book Description
Nutrients in water are necessary for productive aquatic ecosystems, but in high concentrations, nutrients such as nitrates, ammonia, and phosphates can adversely affect aquatic life and human health.
