Monitoring assessment requirements of the ohio river vws compact

Monitoring/Assessment Requirements of the Ohio River VWS Compact

  • No specific mention

  • Article I sets water quality goals for interstate waters, pledges states to work cooperatively to reach them.

  • Article VI sets water quality requirements for intrastate waters.

  • Implied need – status and trends monitoring/assessment.

Monitoring/Assessment Requirements of the Ohio River VWS Compact

  • Article VIII charges the Commission to study the pollution problems of the District.

  • Implied need - any monitoring/assessment effort that identifies causes of water quality problems.


Current monitoring and assessment activities

Current Monitoring and Assessment Activities

  • Monitoring of the Ohio River on behalf of the states

  • Biennial water quality assessment (305[b])

  • Special studies as directed –currently wet weather studies, biological criteria development


Routine monitoring programs

Routine Monitoring Programs

  • Bimonthly ambient monitoring

  • Bacteria and Dissolved Oxygen

  • Fish Population studies

  • Macroinvertebrate sampling

  • Fish Tissue analyses


Orsanco nutrient related activities

ORSANCO Nutrient Related Activities

  • Algae and Nutrient Monitoring

  • Nutrient Criteria Development

  • Participation in Gulf Hypoxia Meetings

  • Nutrient Loading Project

  • Organize and coordinate Ohio River Sub Basin Committee


Algae monitoring

Algae Monitoring

  • Taste and Odor problems in drinking water supplies

  • Need for consistent data

  • Cooperative sampling with water utilities


Nutrient criteria development

Nutrient Criteria Development

  • Need for cause (nutrient) and effect (algae, chlorophyll a) data

  • Desire for multiple observations to define relationships


Current algae nutrient monitoring program

Current Algae/ Nutrient Monitoring Program

  • Cooperative monitoring by ten Ohio River drinking water utilities.

  • Samples collected two times per month.

  • Analyses for algae, chlorophyll a, turbidity, total P, TKN, ammonia N, nitrite + nitrate N.

Orsanco participation in gulf hypoxia deliberations

ORSANCO Participation in Gulf Hypoxia Deliberations

  • Attended meetings on behalf of member states since 1995.

  • Have attended all Task Force meetings.

  • Full Commission met in conjunction with Task Force in 2002.

  • Received funding for 1st year of Sub Basin Committee operation in June, 2005.


Actions assigned to sub basin committees

Actions Assigned to Sub Basin Committees

Estimated peak season total nitrogen loads on selected tributaries (lbs/day/sq.mi.)


Information needs for gulf action plan

Information Needs for Gulf Action Plan

  • Quantify Ohio River nutrient loading to the Mississippi over time.

  • Quantify tributary loads for prioritization.

  • Track tributary conditions to assess program effectiveness


Monitoring program design questions

Monitoring Program Design Questions

  • Can current program meet Gulf Action Plan needs?

  • Can resources be shifted away from criteria development?

  • Role of probabalistic design
