Campbell Marine Water Monitoring Bob Connell Freshwater & Biological Monitoring Al Korndoerfer

4 Water Monitoring & Standards Program Water monitoring, standards & assessment Collect, analyze, & distribute high quality data and information Information used by DEP, other state agencies, federal & local governments, environmental community, business community, & general public

5 Monitoring & Assessment Programs Fresh Water Ground Water Marine & Estuarine Water –Chemical –Physical –Biological

6 Water Management Cycle SWQS Monitoring Assessment 303d List*TMDLs Permit Limits NPS Controls Compliance & Enforcement Impaired? Financing * Integrated Water Quality Monitoring & Assessment Report - Sublist 5 Research

7 Uses of Ambient Water Quality Data 305(b) Report (a primary data source) 303(d) listing/de-listing process Developing waterbody specific TMDL approaches Background / reference data utilized in standards development

8 Freshwater & Biological Monitoring Where do we monitor: Rivers Streams Lakes What do we monitor: Water column chemistry Sediment chemistry Biological conditions In-stream & Riparian Habitat

9 Ambient Surface water monitoring network: Cooperative program with USGS - develops chemical / physical data to establish status and trends in water and sediment quality. –Total of 115 surface water stations Chemical Monitoring

10 Parameters Include: - Nutrients - DO - Bacteriological - Metals - Volatile Organics - Pesticides ( )

11 Ambient Ground water monitoring network: Cooperative program with USGS and NJGS - develops chemical / physical data to establish status and trends in shallow ground water quality. –Total of 150 ground water stations Chemical Monitoring

12 Groundwater Monitoring Network - Shallow well network wells total - Land use-based - Agriculture - Undeveloped - Urban - Parameters monitored: nutrients, VOCs, metals, pesticides, radioactivity

13 Supplemental Ambient Surface Water Monitoring Network Initiated October 2000 Station siting criteria: –Coverage in all HUC 11 units –Integrator locations –At AMNET (Biological) sites –Include tidally influenced sites –Stakeholder input

14 177 Sites for 2 Years of Quarterly Sampling Parameters - nutrients, flow, and field parameters Supplemental Ambient Surface Water Monitoring Network Sites CY

15 Supplemental Ambient Surface Water Monitoring Network Approach Quarterly sampling for two years Oct to Sept –WMAs 1, 2, 3, 6, 8, 9, 10, 12, 18 and 19 Oct to Sept –WMAs 4, 5, 7, 11, 13, 14, 15, 16, 17 and 20

16 Biological Monitoring Ambient Bio-monitoring Network (AMNET) Over 820 stations Sampled 1x/5yrs Uses benthic macroinvertebrates as indicators of river/stream aquatic health Fish Index of Biotic Integrity (FIBI) Supplements AMNET Uses fish number and diversity (variety) as indicators

17 Biological Monitoring –Ambient Biomonitoring Network (AMNET) & Fish Index of Biotic Integrity (FIBI) Both include semi-quantitative assessments of in-stream and riparian habitat quality

18 Ambient Biological Monitoring Network (AMNET) Non-impaired Moderately impaired Severely impaired

19 Fish Index of Biotic Integrity Network (FIBI) N=55 sites 7 (13%) 31 (56%) 16 (29%) 1 (2%) IBI Ratings

20 Ambient Lake Monitoring Network Designed to provide the water quality data necessary to assess ecological health. 200 randomly selected lakes from the ~ 1100 named lakes. 40 lakes monitored per year, 3 times in a year (Early Spring, Summer & Late Fall) Determining status and long-term trends in lake water quality.

21 Ambient Lake Monitoring Network Water quality measurements conducted at each lake include: Dissolved oxygen pH Temperature Specific Conductance Alkalinity Hardness Secchi depths Nutrients, and Chlorophyll a

22 Lakes Selected for Year One of Monitoring

23 Ambient Lake Monitoring Network In addition to this effort to monitor the overall health of our lakes statewide, the state is conducting follow-up monitoring on targeted lakes: Seven lakes, for which ambient monitoring data are needed to determine if restoration activities have been effective, will be monitored over the next five years using the same protocols described for the Ambient Lake Monitoring Network.

24 Targeted Water Quality Monitoring Activities Targeted Monitoring (regional & local): –Impaired Waterbodies List Elevated Flow Metals Monitoring –TMDLs Non-point Source Monitoring (Lower Delaware Basin) Statewide Stream Bacteriological TMDL Source Identification Monitoring Stream specific TMDL Monitoring (Rancocas Creek, Shark River, etc.)

25 Targeted Water Quality Monitoring Activities Targeted Monitoring (regional & local): –Pollution / Impairment Track-down Monitoring Mirror Lake Lead contamination –Automated Water Quality Monitoring Diurnal DOs in streams

26 Targeted Water Quality Monitoring Activities Targeted Monitoring (regional & local): –Biological Monitoring Refinements Pinelands Biometric Development Northern Region AMNET Genus/Species Biometric Development Headwaters Fish IBI Protocol Development
