NMN Objectives and Management Issues
NMN Objective NMN Management Questions Delaware Management
1. Define status and trends of key water quality parameters and conditions on a nationwide basis. What is the condition of the Nations surface, ground, estuarine, coastal, and offshore waters? Where, how, and why are water quality conditions changing over time? Development of management strategies for protecting areas of high water quality.
2. Provide data relevant to determining whether goals, standards, and resource management objectives are being met, thus contributing to sustainable and beneficial use of coastal and inland water resources. Are strategies that protect or remediate water quality working effectively? Are we meeting water quality goals and standards? Environmental sources, transport and effects of contaminants in the region (e.g. PCBs, pesticides, and contaminants of emerging concern).
3. Provide data to identify and rank existing and emerging problems to help target more intensive monitoring, preventative actions, or remediation. What are the water quality problems? Where are the water quality problems? What is causing the problems? Maintain freshwater quantity and quality.
4. Provide data to support and define coastal oceanographic and hydrologic research, including influences of freshwater inflows. What research activities will help us to understand water resources and ensure they are sustainable? Assuring public health (pathogen contamination and fish advisories.)
5. Provide quality-assured data for use in the preparation of interpretive reports and educational materials. All management questions require these data. Potential impacts of nutrient overload and nutrient imbalance in the estuary.

  • Table 1-1 Water Quality Issues from NMN Report
  • Oxygen depletion
  • Nutrient enrichment (arguable)
  • Toxic contamination
  • Sedimentation
  • Harmful algal blooms
  • Habitat degradation
  • Invasions by exotic species
  • Pathogens (indicator bacteria)

7
Technical Needs from Estuary Science Conference

1. Contaminants (forms, sources, fates effects for different classes)
2. Tidal Wetlands (status, trends and relative importance of different types)
3. Ecologically Significant Species Critical Habitats (oysters, benthos, horseshoe crabs)
4. Ecological Flows (effects of flow changes on salt balance biota)
5. Physical-Chemical-Biological Linkages (e.g., sediment budgets, toxics biota)
6. Food Web Dynamics (key trophic connections among functional dominant biota)
7. Nutrients (forms, concentrations and balance of macro- and micronutrients)
8. Ecosystem Functions (assessment and economic valuation of ecosystem services)
9. Habitat Restoration and Enhancement (science policy)
10. Invasive Species (monitoring, management control)
8
Estuary Program Operational Needs
Top Six Operational Needs
1. Strengthen Linkages Between Science and Management
2. Develop a Conceptual Framework Describing the Ecosystem
3. Implement an Ecosystem Management Approach
4. Grow the Monitoring Infrastructure and Link to Improved Indicators and Goals
5. Improve Data Coordination, Compatibility, Quality, Sharing, Access and Archiving
6. Educate Public and Build Identity for Defining Traits and Issues

  • USEPA Regions 2 3
  • NOAA
  • USGS NJ, PA, DE, NY and NAWQA
  • NJDEP, DNREC, PADEP, NYDEC

11

DRB Pilot Study Area Boundary
  • Entire Delaware Basin
  • 4 statesNY, PA, NJ, DE
  • Several Physiographic Provinces and Ecohabitats
  • Major inflowsLehigh, Schuylkill, Maurice, CD
    Canal
  • Bounded by northern and southern Coastal
    endurance lines

12
Data Management Work Group
  • Chairs Eric Vowinkel and Ed Santoro
  • Existing DRBC Monitoring Matrix
  • Will create an ftp site on DRBC computer to store
    exchange of information
  • Water-Quality Data Exchange (WQDE) Networks in
    progress at NJDEP, DNREC, PA?, NY?
  • Exploring options for web-based portal for
    Delaware Basin

Estuary Work Group
  • Chair Jonathan Sharp, UDel
  • Boat Runhistorical monitoring along spine of
    Delaware Estuary
  • Probabilistic network
  • NCA
  • New sites from USEPA Corvallis from Tony Olsen
  • Discussions of mixing probabilistic and fixed
    stations

14
Near-Shore Work Group
  • Chair Bob Connell, NJDEP
  • Issues
  • How far south?
  • 12-miles out into Atlantic Ocean
  • Physical habitat needs
  • Sediments included
  • Biological assessment and productivity
  • Lidar methodsremote sensing
  • Should not be looking at nutrients but rather
    eutrophic conditions
  • Chlorophyll a, DO, macro algae, HABS, nutrient
    loads, wastewater discharges, atmospheric
    deposition
  • Assests
  • Gliders
  • Air craft and satellite remote sensing
  • Boat along coast with NJDEP USEPA
  • Fixed station LEO site from RU
  • DEOs fixed station
  • Optical sensor for DO in future in glider
  • Nuisance algal blooms-by boat
  • Loads from WWTP
  • Maybe some nutrient data from atmospheric
  • Map will be coming

Off-Shore Work Group
  • Chair Scott Glenn, RU IMCS
  • Endurance line off of Tuckerton, NJ
  • Future site off of Delaware

Atmosphere Work Group
  • Chair Lisa Totten, Rutgers
  • Only one NADP site in the Basin
  • Supplemental sites added by NJDEP, DRBC
  • Some sites deactivated

19
Ground Water Work Group
  • Chair Eric Vowinkel, USGS
  • Significant vulnerability of ground water in the
    Delaware Basin to contamination by nitrate in PA,
    NJ, and DE
  • Concentrations of nitrate in ground water are
    largest in agricultural areas and moderate in
    urban area

NMN requirements for rivers
Rivers Flow and loads from inland HUC-6 watersheds Individual watershed 1-3 per watershed 258 sites for conterminous U.S. Sites located to represent 90 of freshwater outflow from HUC-6 watershed Monthly plus high flows (about 15 times per year) Once per year for biological characterization and sediment quality On going
Rivers Flow and loads to estuaries Individual estuary and aggregated for Network estuaries Variable 72 Sites located to monitor 97 of freshwater inflow to Network estuaries and inflow to 70 of Network estuary surface area Monthly plus high flows (about 15 times per year) Once per year for biological characterization and sediment quality On going
Rivers Flow and loads to Great Lakes Individual watershed 1 per watershed 56 Sites located to represent outflow of basins draining 250 square miles or more Monthly plus high flows (about 15 times per year) Once per year for biological characterization and sediment quality On going

Nutrient dry run
  • Results
  • Delaware at Trenton site monitored 4-6 times per
    year for DRBC and PADEP
  • Will be monitored 16 times per year for NAWQA
    Status and Trends in 2008 for nutrients and
    pesticides but only once every four years
  • Site location data well documented
  • Metadata and QA/QC well documented
  • Only Tier 1 nutrients satisfied except for silica
  • Did not meet detection limit for most
    constituents by more than an order of magnitude
  • For Estuary Boat Run more constituents were
    analyzed for in the different Tiers but generally
    did not meet the detection limit requirements for
    nutrients
  • What was done
  • Compared Nutrient IWG recommendations
  • Tier 1required
  • Tier 2add significant value
  • Response variables
  • Ancilliary
  • For Delaware River at Trenton as test case (see
    table)
  • For Delaware Estuary Boat Run Data
