  1. Determining the Comparability of Six Methodologies in New England Becky Weidman, NEIWPCC

  2. Partners • Connecticut Department of Environmental Protection • Guy Hoffman and Ernie Pizzuto • Maine Department of Environmental Protection • Beth Connors and Leon Tsomides • New Hampshire Department of Environmental Services • David Neils • New Jersey Department of Environmental Protection • Al Korndoerfer, Leslie McGeorge, and Victor Poretti • New York Department of Environmental Conservation • Margaret Novak • Vermont Department of Environmental Conservation • Doug Burnham and Steve Fiske

  3. Overview of Talk • Discussion of NEIWPCC’s involvement in the study • Overview of work in New England • Progress to date

  4. Interest in WSA • Methods Comparability • Endpoint, assessment comparability • New England just completed a regional study- NEWS

  5. Involvement in WSA • Work with Region 1 and 2 states to conduct a methods comparability assessment • Methods comparability using the New England Wadeable Streams Survey (NEWS) Protocols • Sampling: • Benthic Macroinvertebrates • General Site Description

  6. NEWS • New England Wadeable Streams Survey • Assessment of the ecological condition of the New England Wadeable Streams using random probability based sampling methods. • 320 sampling locations • 2000-2004 • State methodology comparability component • Development of a Biological Condition Gradient for the region

  7. Overview of Sampling in New England • Utilized NEWS sites • Sampled using the following protocols: • Connecticut • Maine • New Hampshire • NEWS • Vermont • WSA Courtesy of Vermont DEC

  8. Connecticut and Vermont • Kick Net • Connecticut: • USEPA Rapid Bioassessment Protocols (RBP) • Targets richest habitat (riffle) • 12 stops using 800-900 micron net • Vermont: • Comparable to USEPA RBP • Targets riffle habitat • 4-5 stops using 500 micron net

  9. Maine and New Hampshire • Rock baskets • Maine: • Distributed throughout habitat • 4 weeks • New Hampshire: • Tethered to bottom in one location • 6-8 weeks

  10. NEWS • USEPA RBP (updated) • Multi-habitat • 500 micron kick net

  11. WSA • Updated USEPA RBP • 500 micro kick net • Multi-habitat • Samples collected along 11 transects

  12. Sampling in 2004 • National Wadeable Streams Survey • Sampled during same index period • 23 sites using all six methods

  13. Sampling in 2005 • An additional 20 sites were sampled throughout the region • Sampled using state and national protocols • Sampling was completed

  14. Progress to Date • Sampling is complete • Macroinvertebrate sample identification will be completed in the summer of 2006 • During the fall of 2006, NEIWPCC, our state partners and EPA will be working to analyze our results • NEWS report should be available in 2006
