History
• Facilitate coordination
of regional-based
nutrient criteria and
biocriteria for
waterbodies of USEPA
Region 7.
Region
Nutrient and Biocriteria
Workgroups
• EPA's Clean Water Action Plan 1998
• Goal – protect aquatic life from nutrient
overenrichment.
• USEPA Region 7, Kansas City
• Nebraska
• Iowa
• Kansas
• Missouri
Nutrient Criteria
• Goal – establish draft benchmark nutrient criteria for
lakes, streams, and wetlands of the US EPA Region
7 and the Central Plains Region.
Streams
Nutrient Criteria cont’d
Biocriteria workgroup
• Goal - adoption of narrative biological criteria as part of
State water quality standards.
• Annual meetings (workshops) available on website.
• Symposia open to others.
• Currently macroinvertebrate database to examine
reference stream conditions.
National Park Service
• Heartland Network Inventory and
Monitoring Program
• Develop monitoring plan for surface waters
• Literature, database, GIS, analyses
• 15 parks
DO monitoring
• Kansas TMDL streams
• Measure DO levels in water column and oxygen
demand (BOD and SOD)
• Long-term productivity at Soldier and Cedar
Creeks

Wadeable Stream Assessment
• National EPA study on over 500 randomly
chosen streams
• Follow-up to study in Western and Atlantic
states
• REMAP methods
• Sample TX and NE streams
• Sort and identify macroinvertebrates from
TX, NE, KS, MO, and OK
