The Super Bowl Flush It is estimated that at halftime of the Super Bowl, across the United States 90 million people will flush about 350 million gallons of water down the toilet at the same time. It is equivalent to the amount of water that flows over Niagara Falls every 39 minutes.Niagara Falls

MDCB New Directions From recent Board & Council meetings— issues consistently raised include Contaminants Sensors Statistical methods Event, continuous, and real-monitoring Need to prioritize issues based on needs of the water- quality community including the National Network

Contaminants--Problems New analytical methods to detect a wider range of contaminants in the hydro/geo/biological cycles Contaminant MRLs are decreasing orders of magnitude Are results from these new methods comparable? Emerging contaminants – is there a process for identifying what contaminants should be of concern?

Emerging Contaminants: Identification, Concerns, Actions - Roland Hemmitt, EPA Region 2 USGS National Program Efforts in Emerging Contaminants – Herb Buxton, USGS Toxic Substances Hydrology Program Emerging Contaminants: Monitoring & Standards Development – Leslie McGeorge, NJDEP Perchlorate Case Studies: –Potable Water Occurrence & MCL Development – Judy Louis, NJDEP/Division of Science, Research &Technology –Surface Water Monitoring - Tom Vernam, NJDEP/WM&S The Effects of Water Treatment on Emerging Contaminants – Jeff Fischer, USGS NJ Water Science Center Monitoring Emerging Contaminants in Groundwater – Mike Serfes, NJDEP/NJGS Monitoring Emerging Contaminants in the Tidal Delaware River – Ronald MacGillivray, DRBC Emerging Contaminants NJWMCC Meeting—1/23/08

Emerging Contaminants Human Drugs Veternary Drugs Antibiotics Hormones Steroids Detergents Plastics Antioxidants Fire retardants Disinfectants Fumigants Fragrances Insecticides Repellants Plastics Coal tar sealants Algal toxins Nanoparticles Perfluoronated cmpds. Personal care products

Contaminants--Objectives Recommend a list of contaminants to be monitored in the Network Prioritize the contaminants into high, medium, and low need by hydrologic compartment Determine appropriate MRLs appropriate in each hydrologic compartment Suggest appropriate analytical methods

Sensors--Problems Sensor technology is evolving rapidly No central repository available to compare MRLs, precision, bias, “greenness”, etc Comparability of results among sensors is poorly understood The Network recommends placement of continuous real-time sensors in estuaries but guidance on types of sensors and frequency of data collection is limited

Sensors--Objectives Develop a white paper to outline the approach Store sensor technologies in a database like NEMI Create a web-site to guide users on sensor use Outside experts –EPA ETV Program –Sandia National Labs (SNL) –Department of Defense (DoD) –Homeland Security (DHS) –Private sector –USGS users

Statistical Methods--Problems Monitoring networks may include different designs: discrete probabilistic continuous satellite imagery The National Monitoring Network is a network of networks Sites selected differently Data collected at different frequencies Is it possible to integrate discrete, probabilistic, continuous, and satellite data sets generated by the Network or other networks? If so, how can we integrate and use the data effectively?

Statistical Methods--Objectives Connect with the Council’s Water Information Strategies (WIS) Work Group to evaluate methods of analysis of available data sets Provide guidance on: –appropriate use of statistical methods and reporting of data from the Network and other monitoring efforts –methods to integrate various data sets

Event, Continuous, and Real-time Monitoring -- Problems Network river sites: Sample 16x per year with consideration for flow conditions What constitutes an “event”? For event samples, what type of sample collection technique is appropriate? Continuous and real-time sensors are to be used at estuary sites What frequency of capturing/reporting data from continuous monitors is optimal? What are the best methods to estimate contaminant loads from rivers to estuaries to coastal areas?

Event, continuous, and real-time monitoring--Objectives Provide guidance on: appropriate sampling methods and frequency of sample collection for event monitoring magnitudes of events and methods to collect comparable samples appropriate frequency of capturing/reporting data from continuous monitors methods of estimating loads from rivers to estuaries to coastal waters:
