A small building where water is stored? Watershed: area of land whose water flows to a certain lake or river.

Drink? After treatment, Yes Swim? No – no designated swimming areas Safe to eat the fish from tidal/estuarine areas? High Risk Individuals: infants, children, pregnant women, nursing mothers, women of childbearing age Estimate 1 in 10,000 risk of cancer during your lifetime from eating fish at the advisory level. www.state.nj.us/dep/dsr/fishadvisories/ Safe to eat the fish from freshwater areas? No specific fish consumption advisory for any fresh waterbody in the watershed. Safe to boat or fish? Not clear cut Based on sampling at several points, NJDEP declared most of the watershed as not supporting secondary contact recreation; at some times and at some locations, the standard for pathogen indicators was exceeded. What is the risk of getting sick? Depends on where you go, when you go, how careful you are. Typically worse after a storm; better in cold weather A lot of people fish and a lot of people boat – and they keep on doing it. CAUSES OF POLLUTION Quiz -- In the United States as a whole, what is the most common cause of pollution that impairs use of streams, rivers and oceans? a. Dumping of garbage directly into waters b. Rainfall washing off pollution from yards, streets, parking lots, and farms c. Contaminated soil and leaking tanks at old, this abandoned factories. We call “nonpoint source pollution” – d.

Economic Effects of Water Pollution • Diminished value of near-water properties • Lost business opportunities servicing River users • Unavailable for drinking and/or industrial uses; increase treatment costs • Physical and mental health care costs and lost productivity resulting from diminished recreation and relaxation HARD TO PUT A NUMBER ON THESE SOLUTIONS: Approaches for Reducing Urban, Nonpoint Water Pollution • Regulatory Approaches – NJ Stormwater Management Rules – Municipal Stormwater Regulation Program (MS4 permitting program) – Total Maximum Daily Loads (TMDLs) • Regional Stormwater Management Plans • “Green” redevelopment • Education for behavioral change – organizational (municipalities and business) – personal, household NJ Stormwater Management Rules effective February 2004. • Strict for major “new” development (>.25 acre of new impervious surface) – infiltrate stormwater into the ground – high quality discharge • Not too strict for redevelopment (rebuilding on existing impervious surfaces) see njstormwater.org BR AN CH EA ST WEST BRANCH § ¨¦ 78 K OO BR I ZA EL T BE MA NO AN HEG Newark R I VE HR £ ¤ SO UT H BR A NC H GSP § ¨¦ 95 1 K M ST E § ¨¦ £ ¤ C ES EK RE SC SE IN MA ROBINSONS BRANCH RS MO R MO 22 Parcels with a change in type of Land Use, 1995 to 2002 Municipal Stormwater Regulation Program Municipal Separate Storm Sewer (MS4; “Phase 2”) Permit Program (started in 2004) Don’t feed the geese Total Maximum Daily Loads (TMDLs) • Determination of the maximum amount of a certain pollutant that a river or lake can receive while still meeting designating uses • If there is a failure to meet designated use, the state must – develop a TMDL for the offending pollutant – develop a plan for reducing the load to below the TMDL • Areas not meeting secondary contact standard are under a TMDL for pathogen indicators – but implementation plan is not very specific • Prescribes 95% reduction in Fecal Coliform! “Regional Stormwater Management Plans” Robinson’s Branch Project www.water.rutgers.edu/Projects/Robinsons/Robinsons.htm Proposes numerous ordinances, educational initiatives and in-the-ground projects •requiring low/no phosphorus fertilizer •forbidding no coal tar as asphalt sealant •requiring registration/education of landscaping professionals •creation of a stormwater utility authority •catch-basin cleaning program •goose management •streambank stabilization “Green” redevelopment aka “Low Impact Development” BASIC APPROACH 1. Reduce volume of runoff by … • reduce amount of impervious cover • infiltrate stormwater into the ground 2. Reduce peak flow rate of runoff by … • reduce volume of runoff as per #1 • detention pond, wetlands 3. Reduce pollutants in discharge by … – detention ponds, wetlands, manufactured treatment devices NOTE LOSS OF SIDEWALKS Constraints • retrofits expensive and disruptive • very little land to use in urban areas • market acceptability still unproven for some practices • long-term performance unproven Education for Behavioral Change • It’s relatively cheap • But … – it is very difficult and never ending – Progress is slow How do you reach people and get them to change? Education for Behavioral Change • Brochures – many available www.cleanwaternj.org www.epa.gov/enviroed How effective is distribution of information? • • • • Events, esp. Earth Day. River clean-ups Presentations to Community Groups (scouts) School programs New Jersey Watershed Ambassadors will help www.nj.gov/dep/watershedmgt/ ambassadors_index.htm SIMPLE THINGS YOU CAN DO (OR STOP DOING) Don’t apply pesticides – they can runoff into the river and cause harm Without pesticides, your lawn will still look ok, and you can be sure it’s safe for kids, pets and vegetables – you’ll never see this on your lawn! Which is more important to you: a weed free lawn or the health of kids and pets? Are clover and dandelions weeds or wildflowers? So-called “weeds” can add beauty and fun to your lawn. If you like them, they aren’t weeds! Never dump oil or other chemicals down a storm drain inlet (or anywhere else) Take them to an oil recycling center or to hazardous waste collection day • Drive your car less • Make sure its not leaking fluids • Don’t wash it on the driveway More at www.cleanwaternj.org The End Passaic River Institute, Montclair State University email: pri@montclair.edu web: www.primsu.org 973-655-7117 Dr. Kirk Barrett, Director Re- Acknowledge NJDEP Bureau of Water Monitoring and Standards; Bureau of Geographic Information Systems
