Book Description
A benthic macroinvertebrate survey was conducted on the Butternut Creek, Otsego County, New York. Samples were collected from 18 sites between Basswood Pond and the confluence of Butternut Creek and the Unadilla River from 1 July 2002 to 15 July 2002. Assessments of physical habitat (PHA), family biotic index (FBI), percent model affinity (PMA), and percent Ephemeroptera, Plecoptera and Trichoptera (%EPT) were made at each site. Mean assessment results indicate that the habitat and water quality of Butternut Creek is in good condition. PHA results of 94.17 (+/- 19.42) indicate optimal habitat. Percent EPT values of 50.56 (+/- 20.98) are in the non-impacted range. FBI data averages 4.26 (+/- 1.16) revealing a non-impacted condition. A PMA of 62.61% (+/- 13.20) places the water quality in the slightly impacted range. The benthic community at each site was broken down according to functional feeding group (FFG). A significant decline in shredder populations was found as sampling proceeded down the course of the stream. No relationship was found between location on the stream and PHA. PHA did not have a significant effect on FBI, PMA or %EPT scores at each site.

Book Description
The city of Pittsburgh and surrounding area of southwestern Pennsylvania face complex water quality problems, due in large part to aging wastewater infrastructures that cannot handle sewer overflows and stormwater runoff, especially during wet weather. Other problems such as acid mine drainage are a legacy of the region's past coal mining, heavy industry, and manufacturing economy. Currently, water planning and management in southwestern Pennsylvania is highly fragmented; federal and state governments, 11 counties, hundreds of municipalities, and other entities all play roles, but with little coordination or cooperation. The report finds that a comprehensive, watershed-based approach is needed to effectively meet water quality standards throughout the region in the most cost-effective manner. The report outlines both technical and institutional alternatives to consider in the development and implementation of such an approach.
