NJDEP Water Monitoring and Standards
Barnegat Bay Ambient Monitoring Project
National Conference Presentation and
Phase 2 Activities (Apr-Dec, 2012)
Presented by:Leslie McGeorgeNJWMC MeetingMay 30, 2012
NJDEP Water Monitoring and Standards
Barnegat Bay Water Quality Monitoring Program: Objectives
• Determine type and extent of water quality impairments
• Develop models for use in directing water quality restoration or TMDL development
• Based on pollutant load responses, identify water quality or loading targets for nutrients or other pollutants
NJDEP Water Monitoring and Standards
Partnership Development• How find interested & willing partners?
• Start w/ NJ Water Monitoring Council • USGS, EPA, Water Utility, Planning Commission, University, Estuary
Program • Meet w/ entities - ask what they can do?• Add monitoring & lab partners
• County Health Dept, Local Technical High School & Sewage Utility, University, & Health Dept
• Find partners in our own agency QA Office, Forestry Center facility, AmeriCorps
• Retask existing partner work - e.g. USGS flow work
• Now have 13 partners!
NJDEP Water Monitoring and Standards
Partnership Development• Monitoring Agreements – written agreements
with each entity specifying project commitments
• Comprehensive Quality Assurance Plan- Referred to in all Partner Agreements
- Assure data of known quality & comparability of results
- Includes: Station locations/dates/ timesSample preparation – preservation & filtering in 2 labsParameters, analytical & field methodsData quality requirements/ reviewSample routing Chain of custody forms

Partnership Development
• Training & QA Approval- Partner meetings on project design, sample collection, equipment calibration, and QA Office approval for field measurements ( DO, SC, T)
• Partner Communication – 1 point agency contact overall project, 1 field contact for tribs and 1 for bay, frequent emails
• Data access – Website w/ Interactive map

What’s New in Phase 2?• New Partners
• New/Changed– Water Quality Stations
• Changed– BT06 (Cedar Creek @ Lanoka Harbor)
flow gauge & wq station relocated– BB04, BB05, BB07
moved to better catch representative wq signal• New
– BB00/BT00 (Point Pleasant Canal)
– Air Deposition Monitoring - TN• Site selection (possibly Cattus Island or BTMUA?)
NJDEP Water Monitoring and Standards
What’s new in Phase 2 (cont)• Bottom Parameters (~1 ft from bottom)
– pH, temp, DO, salinity, TP, TN, Total Silica, TSS, Chlorophyll a, TOC, BOD
• Continuous WQ MonitoringDO, pH, temp, turbidity, conductivity, nitrate/nitrite (trib), chlorophyll a (bay)
– Fixed WQ at Gauges: BT03 (Toms River) and BB01 (Mantoloking) – Buoys: BB07a (below Oyster Crk), BB 10 (above Westeconk Crk), BB 14
(LEH inlet). BB04a (near mouth of Toms River)
– HOBO Temp Data Loggers – Phase 1: Oyster Crk; Phase 2: catch thermal plume near mouth of Oyster Crk
• Increased Sampling Frequency– Ambient Monitoring (weekly – Apr-Sept, monthly – Oct-Dec)– 2 Intensive Events (July 23-26 & August 16-19)
