Survey Of Two Perfluorinated Organic Compounds (Pfoa And Pfhxa) In Water And Biota Surrounding A Polyfluorinated Chemical Plant, Kevin S. Dillon
Survey Of Two Perfluorinated Organic Compounds (Pfoa And Pfhxa) In Water And Biota Surrounding A Polyfluorinated Chemical Plant, Kevin S. Dillon
Gulf and Caribbean Research
Perfluorooctanoic acid (PFOA) and perfluorohexanoic acid (PFHxA) concentrations were measured in water and biota samples collected within and near a polyfluorinated chemical plant in coastal Mississippi. Effluents from the site and from the local public water treatment plant were sampled along with municipal water supplies, shallow groundwater beneath the site, nearby surface waters, and local biota. Highest concentrations were from stormwater ([PFOA] = 85—530 ng/l; PFHxA = 140—590 ng/l) and shallow groundwaters ([PFOA] = 44—1000 ng/l; PFHxA = 210—3100 ng/l) collected at the site. The local public water treatment effluent also had relatively high PFHxA concentrations (310—590 ng/l). Intermediate PFOA …
Examining Potential Residential Participation In Financial Incentives To Mitigate Impervious Surface Effects In Howard County, Maryland, Kristin M. Larson, Jim Caldwell, Alexander Cloninger
Examining Potential Residential Participation In Financial Incentives To Mitigate Impervious Surface Effects In Howard County, Maryland, Kristin M. Larson, Jim Caldwell, Alexander Cloninger
Suburban Sustainability
Maryland passed legislation to reduce impervious surface effects and stormwater runoff by mandating a remediation fee for ten of its counties. Along with the fee, mandated counties may use funds generated to encourage residents to follow stormwater Best Management Practices (BMPs). This study uses Maryland's Howard County as a case study to examine the potential participation of its residents in financial incentives for the BMPs of rain gardens, cisterns, and permeable pavers. A survey was issued to gauge potential participation of homeowners (n=110), and results were then compared to participation numbers in three similar already implemented financial incentive programs. Results …

Stormwater runoff can transport nutrients, sediments, chemicals, and pathogens to surface waterbodies. Managing runoff is crucial to preserving water quality in rapidly developing urban watersheds like those in Northwest Arkansas. A watershed containing the majority of the University of Arkansas campus was designated as the study area because stormwater from it drains into the West Fork of the White River, designated as an impaired waterbody due to siltation. The project objective was to develop methodology to test existing stormwater drainage infrastructure, identify potential areas of improvement, and estimate potentially contaminated runoff by combining two widely used prediction models. The U.S. …
