  • Pollution at the nation’s 3,500 ocean, lake and bay beaches resulted in more than 25,000 closing or swimming advisory days last year, 28 percent more than in 2005, and the highest number in the 17 years that records have been kept, according to a new federal report released Tuesday.
  • he prime culprit was storm water runoff
  • Another 1,300 days were attributed to sewage spills and overflows.

  • “Exposure to bacteria, viruses and parasites in contaminated beach water can cause a wide range of diseases, including ear, nose and eye infections; gastroenteritis; hepatitis; encephalitis; skin rashes; and respiratory illnesses,”
  • Most at risk are small children, pregnant women, cancer patients and others whose immune systems are weak or compromised.
  • “Children under the age of 9 had more reports of diarrhea and vomiting from exposure to waterborne parasites than any other age group,”
  • “found that more than 10 percent of swimmers report contracting gastroenteritis or respiratory infections after swimming. Based on those results and beach attendance numbers, nearly 300 people could expect to contract a respiratory illness after swimming in Lake Michigan in Chicago on a summer weekend.
  • “The study found skin rash and diarrhea to be consistently significantly elevated in swimmers compared to non-swimmers.
  • For diarrhea, this risk was strongest among children 5 to 12 years old,
  • an estimated 27 cases per 1,000 among children with any water contact, 32 cases among those with facial contact with the water, and 59 cases among those who swallowed water,
  • 92 beaches in 19 states as being “high risk”
  • 25 percent of tests.
  • “Aging and poorly-designed sewage and storm water systems hold much of the blame for beach water pollution. The problem was compounded by record rainfall, which added to the strain on already overloaded infrastructure.

Oil Remains - 0 views

  • largest and most productive estuaries in North America.  
  • However, in 1993 the EVOS Trustee Council funded an additional survey that estimated 7 km of shoreline were still contaminated with subsurface oil.
  • Because a significant survey of Prince William Sound had not been conducted since 1993 and the cumulative extent of the remaining oil was unknown, concerns were generated by the public and scientific communities about the oil’s possible continuing effects on humans and fauna potentially exposed to the oil directly or indirectly.

  • Without an accurate assessment of the extent of the remaining oil, subsistence food-gatherers, consumers of commercial fish products from the area, and tourists have used mostly anecdotal evidence as the basis for economic decisions regarding resource utilization in the affected area.
  • Consequently, the Auke Bay Laboratory (ABL) with funding from the EVOS Trustee Council, took on the task of assessing the remaining oil along the shorelines of Prince William Sound during the summer of 2001
  • The primary objective of the project was to measure the amount of oil remaining in the intertidal zone of Prince William Sound.  Secondary objectives include determining the rate of decline of oil on these beaches, estimating the persistence of the remaining oil, and correlating the remaining oil with geomorphological features.
  • heavily and moderately oiled
  • The 2001 survey adopted a stratified random/adaptive sampling (SRAS) design. Two random pits were excavated to a depth of 0.5 m (1.6 feet) in every stratified block (0.5-m verticle drop in tide height) within a grid system established at each site. If subsurface oil was discovered in any of the randomly stratified origin pits, then additional adaptive pits were excavated above, below, to the right, and to the left of the origin pit until the extent of the oil patch was determined.
  • Buried or subsurface oil is of greater concern than surface oil.
  • Subsurface oil can remain dormant for many years before being dispersed and is more liquid, still toxic, and may become biologically available.
  • A disturbance event such as burrowing animals or a severe storm reworks the beach and can reintroduce unweathered oil into the water.
  • The toxic components of this type of surface oil are not as readily available to biota, although some softer forms do cause sheens in tide pools.
  • 1) Surface oil was determined to be not a good indicator of subsurface oil. 2) Twenty subsurface pits were classified as heavily oiled.  Oil saturated all of the interstitial spaces and was extremely repugnant. These “worst case” pits exhibited an oil mixture that resembled oil encountered in 1989 a few weeks after the spill - highly odiferous, lightly weathered, and very fluid. 3) Subsurface oil was also found at a lower tide height than expected (between 0 and 6 feet), in contrast to the surface oil, which was found mostly at the highest levels of the beach (Table 3).  This is significant, because the pits with the most oil were found low in the intertidal zone, closest to the zone of biological production, and indicate that our estimates are conservative at best.
  • The possibility of continuing low level chronic effects of the Exxon Valdez oil spill seem very real now, although measurable population effects would be very difficult to detect in wild populations.
  •  Sea otters and harlequin ducks fall into this category
  • such as sea otters, harlequin ducks, and their intertidal prey.
  • The last beach assessment was completed in September 2001. Supporting chemical analyses will be completed in fall 2002, and a final report with statistical analyses and conclusions will be completed by April 2002.

  • The western portion of Prince William Sound was the most heavily oiled in 1989 and oil on some beaches remains a serious concern for residents of the Sound who use these areas.
  • The remaining 1,100 miles of oiled shoreline were considered to have light to very light oiling. Crews visiting beaches in 1993 found hundreds of sites that contained substantial oil deposits.
  • A 1992 National Oceanic and Atmospheric Administration (NOAA) study* estimated that a great majority of the oil evaporated, dispersed into the water column or degraded naturally.

  • Post-cleanup analyses in 1998 showed that while the cleanup method was largely effective in removing visible surface oil, it had little effect on the large deposits of oil beneath rocks and overburden.

Exxon Valdez - 0 views

  • It gained widespread infamy after the March 24, 1989 oil spill in which the tanker, captained by Joseph Hazelwood and bound for Long Beach, California, hit Prince William Sound's Bligh Reef and spilled an estimated 10.8 million US gallons (40.9 million liters) of crude oil.
  • This has been recorded as one of the largest spills in U.S. history and one of the largest ecological disasters.
  • At the time of the spill it was employed to transport crude oil from the Alyeska consortium's pipeline terminal in Valdez, Alaska, to the lower 48 states of the United States.

  • The vessel was carrying about 1.26 million barrels, or about 53 million US gallons (200 million liters), of oil at the time it ran aground.
  • On August 27, 2008, Exxon Mobil agreed to pay 75% of the $507.5 million damages ruling to settle the 1989 Exxon Valdez oil spill off Alaska.

Document Page: BETTER DATA AND EVALUATION OF URBAN RUNOFF PROGRAMS NEEDED TO ASSEDD EFF... - 0 views

  • The Chesapeake Bay, forexample, has been polluted with the nutrients nitrogen andphosphorus and with excess sediment caused, in part, by urbanrunoff. The excess nutrients cause algae blooms that blocksunlight from reaching bay grasses-which are a source of food,shelter, and nursery grounds for many aquatic species.
  • In aneffort to control nutrient pollution in the Chesapeake Bay, theExecutive Council of the Chesapeake Bay Program" established agoal to reduce the nitrogen and phosphorus entering theChesapeake Bay by 40 percent, including through control of runofffrom urban areas.

      The Santa Monica Bay Restoration Project conducted a study to identify adverse health effects of untreated urban runoff by surveying over 13,000 swimmers at three bay beaches. The study established a positive association between an increased risk of explains health outcome measures at various distances from storm drains. For example, the study found a 1-in-14 chance of fever for swimmers in front of the drain versus a 1-in-22 chance at 400 or more yards away.
  • Pathogens such as bacteria and viruses, which are often presentin urban runoff, can pose public health problems.
  • Drains Versus 400 or More Yards Away Found On Hard Copy-Storm Drain Runoff," Epidemiology, July 1999, Vol. 10, No. 4.Metals and polycyclic aromatic hydrocarbons (PAH) in urban runoffcan present a threat to aquatic life.
  • proved to betoxic to sea urchin fertilization in the Santa Monica Bay, anddissolved zinc and copper were determined to be contributors tothis toxicity. -Brown bullheads (a bottom-dwelling catfish) inthe Anacostia River developed tumors that were believed to becaused by PAHs associated in part with urban runoff. High PAHand heavy metal concentrations were found in crayfish tissuesamples from several urban streams in Milwaukee. The studyassociated these contaminants with storm water runoff.
  • The three primaryactivities used in these programs include efforts to characterizestorm water runoff; BMPs aimed at reducing pollutants in stormwater runoff to the maximum extent practicable; and reportingprogram activities, monitoring results, and costs of implementingthe program. Some BMPs are structural-meaning that they aredesigned to trap and detain runoff until constituents settle orare filtered out.
  • -good housekeeping" practices by the local government, such asoil collection and recycling, spill response, household andhazardous waste collection, pesticide controls, flood controlmanagement, and street sweeping; -public education programs, suchas storm-drain stenciling, to remind the public that trash, motoroil, and other pollutants thrown into storm drains end up innearby receiving waters;' -new ordinances to control pollutionsources, such as prohibiting the disposal of lawn clippings instorm drains and requiring pet owners to clean up after theirpets;" requirements that developers comply with storm waterregulations and incorporate erosion and sediment controls at allnew development sites; -requirements that runoff from propertiesowned or activities sponsored by the municipality be properlycontrolled; and -efforts to identify and eliminate illicitconnections and illegal discharges to the storm sewer systems,such as those from pipes carrying sewage.
  • Several officials in the cities we visited said that their annualcosts are likely to increase. A number of factors could affectthe costs. For example, a Baltimore City official explained thatthe anticipated, future program costs depend on several factors,including (1) requirements in watershed- management planscurrently being developed, (2) pollution-reduction goals the citywill be required to achieve, (3) requirements of the stateregulatory agency in future permits, and (4) requirements thecity may have to meet if TMDLs or numeric effluent limits areincorporated into NPDES storm water permits. Other city officialsalso expressed concern about the extent to which TMDLs couldaffect their future costs. These city officials are concernedthat when and if TMDLs are established, their future storm waterpermits may require that storm water runoff meet specific waterquality standards. For example, Los Angeles County's trash TMDLcould potentially drive the county's storm water management costsupward, and the county expects additional TMDLs to be imposed. Onthe other hand, Worcester officials estimated that their futurestorm water costs would be about the same as they were at thetime of our review-about $4.5 million per year.
