WCEE’s Lunch & Learn Series presents

What’s Bugging Our Streams?  Biocriteria and Water Quality Standards

The streams of America are home to a diverse array of different kinds of creatures, and the abundance and composition of these plant and animal communities can be evaluated to determine biological water quality of a waterbody. How is this done?  How are the results legally judged and enforced? 

Join WCEE to learn about and discuss the current state and future of biocriteria science and law. Our speakers will address the following questions and more on this issue:

  • What is the legal framework governing biological water quality?
  • What are narrative and numeric nutrient criteria and biocriteria?
  • How do we use biological criteria to identify the stressors and assess the cause of an impairment of water quality?
  • What are common pitfalls and difficulties of using biological criteria to assess and enforce water quality?
  • What are the future directions of scientifically rigorous biocriteria development?
  • How are regulators using biocriteria in enforcement and permitting?
  • How do you determine responsibility when numeric effluent limits are met but downstream water quality standards are not?

Date: Thursday, May 11, 2017
Time: 12:00 noon to 1:30 pm
Venue: Beveridge & Diamond, 1350 I St NW, #700, Washington, DC 20005

Closest Metro: McPherson Square
Cost: $0 (WCEE members); $15 (non-WCEE members)

This is a Lunch & Learn (i.e. brown-bag) event; beverages and dessert will be provided but please bring your own lunch.
