You Can Still Enjoy the River During Dredging

Wednesday, June 17th, 2009
go to EPA's Hudson cleanup site
In 2009 dredging began in the Upper Hudson River to remove sediments with PCBs. Read more

With the formidable, 40-mile-long Hudson River dredging project underway, some people may have the idea that the river is off limits for recreation, but this isn’t the case. Granted there are a lot of project vessels on the water, especially around Rogers Island in Fort Edward, but by taking basic precautions for safety, people can use the river in all the ways they have in the past. As a matter of fact, the flurry of activity involves a lot of neat construction equipment, and people can visit the yacht basin in Fort Edward to see the dredging up close and personal.

To scoop the 400,000 tons of sediment (more than 94 acres) targeted this year, GE has mobilized an armada of equipment, including 11 dredges, 17 tugboats, 20 barges, and more than 400 rail cars, as well as skiffs, cranes and other machinery. At peak dredging during July and August, as many as 80 to 90 vessels are expected to be in the river each day. That’s a lot of water traffic congestion in a relatively narrow section of the Upper Hudson, but the river remains navigable by commercial and recreational boaters and open to water skiers, kayakers, swimmers, and anglers.

Boaters traveling in areas where dredging is being performed are being asked to avoid work areas, which are marked by buoys. New York State Canal Corporation regularly posts project information for boaters on their website. EPA and the New York State Department of Health representatives have been telling people recreational activities such as swimming and water skiing are acceptable during dredging, but individuals should try to avoid the immediate areas where dredging is being performed to minimize the potential for exposure. Also, people are being reminded to wash off after going in the water, not just because of PCBs, but because unfiltered river water is known to contain bacteria, viruses and other “bugs” that can make people sick. People are surprised to learn that they can still swim in the river with the project going on, but the main risk of exposure to PCBs at dangerous levels is through eating contaminated fish — and, for now, fish are strictly for catch and release in the Upper Hudson.

What About Where You Live?

Friday, June 12th, 2009

How much do you know about the environment of where you live? That’s right, not the rain forest, not the polar icecaps, but your neighborhood. Lots of us take our environment for granted. Water comes out of spigots and waste gets carted or flushed away. Unless there’s an environmental problem nearby, like a polluting factory, most folks don’t give it a second thought. Our environment just is.

But environmental protection starts at home, and it is important to understand how one thing affects another, so here’s the challenge (actually a great project for a class to do) – find out and then write up a report so others can understand your local environment too.

I did this a few years ago for the town in which I live, Narberth, Pa. I looked into:

  • How our electricity is produced.
  • Where the oil that runs my heater came from.
  • Where the natural gas that runs my stove came from.
  • The origin of my drinking water.
  • Where my wastewater goes.
  • What happens to the recyclables (plastics, paper, glass) that are collected.
  • What happens to our yard waste that’s picked up.
  • Where my household waste/trash goes.
  • The quality of the air I breathe.
  • The levels of radon from the ground.
  • What happens to our rainwater after it goes down the storm drains.
  • The name of our watershed and the location of our streams.
  • Our climate and planting zone.
  • Where our gasoline comes from.
  • What mass transit is available.
  • Our topography and geography.
  • How our town is zoned.
  • The location of our historic buildings.

In the process I discovered some interesting things. Some streams had been piped underground and weren’t on the surface anymore. Our household waste goes to an incinerator where it is burned to produce electricity. Our rainwater goes directly into streams; it’s not treated first. The oldest intact structure in Narberth is a Swedish log cabin. But since it has had many additions, it just looks like a normal house now.

My report is on the web at: http://www.narberthpa.org/environment.htm. Feel free to use it as a model for yours. Go out and discover your local environment!

Science Wednesday: A Case of Crabs and People

Wednesday, June 3rd, 2009

About the author: Steve Jordan’s environmental career is rooted in a childhood spent in the woods and creeks of suburban Maryland and along the shores of Chesapeake Bay. After graduate school and a couple of decades working in Chesapeake Bay science and management, he joined EPA’s Office of Research and Development as a scientist and manager at the Gulf Ecology Division.

Before the 1970s, intense development of our coastal areas was limited mostly to scattered resort cities separated by large areas of sparsely populated or undeveloped land. As population grew and roads improved, coastal development exploded—and sprawled.

Beach front high-rises are the most obvious result of all that coastal development, but the whole complex of barrier islands, back bays, bayous, and tidal rivers along our Atlantic and Gulf coasts is now arrayed with homes, businesses, roads, golf courses, docks, bulkheads, and everything else that comes with development. Gulf of Mexico coastal watersheds lost over 370,000 acres of wetlands from 1998 to 2004, mostly to development (see: U.S. Fish and Wildlife Service).

Except for the occasional hurricane, the coastal zone is wonderful habitat for humans. It is also essential habitat for many kinds of animals and plants, including the fish and shellfish that shore residents cherish.

Do the habitat needs of humans conflict with the habitat needs of other coastal residents? Our research at EPA’s Gulf Ecology Division indicates that they can. With my coauthors, Lisa Smith and Janet Nestlerode, I developed a mathematical model to simulate how loss of seagrasses and salt marshes could affect the important blue crab fishery in the U.S. Gulf of Mexico.

The model used information from many existing small-scale studies of how tiny, young (juvenile) crabs depend on aquatic vegetation until they are large enough to avoid predators. We linked data from these studies to electronic maps of the essential habitats and long-term, Gulf-wide commercial fishery data.

Putting it all together, we were able to predict that minor, local losses of essential habitats, multiplied many times in many places, could have serious negative effects on the future of the crab fishery. The main scientific advance in this work has been to make a connection between small-scale ecological studies and large-scale population modeling as it is used in fishery science.

With colleagues from the Pacific Coast and elsewhere, we are extending this type of research to other species and coastal areas. We hope this research will contribute to better understanding of the cumulative effects of coastal development on ecosystems and valuable ecological resources.

Shoo Fly, Don’t Bother Me! (‘cause I’m studying wetlands!)

Friday, May 22nd, 2009

Go to EPA's Science Month pageAbout the author: Dale Haroski is the Science Advisor to the Office of Public Affairs. Even with years of field work and a doctorate in Ecology and Evolution, she has endangered her fiancé’s life several times after abandoning the driver’s seat (while moving) to flee from assorted small spiders and insects.

Ask any wetlands ecologist what life is like in the field and, if they’re honest, you be regaled with tales of long days and longer nights, weather, mud, being stuck in the mud, boats breaking down, people breaking down and bugs – lots and lots of bugs.

All of my graduate research took place in east coast estuaries where seemingly serene swaying fields of salt grass hide one of the most ferocious and fearsome predators known to ecologists and beachgoers alike: the greenhead fly. I know what you’re thinking, “It’s a fly! Sure they’re annoying but aren’t we being a little dramatic?” If you’re thinking this then you’ve clearly never experienced Tabanus nigrovittatus. With razor sharp mouth parts and giant green eyes capable of tracking a target with military precision, the greenhead is impressive, intimidating and seemingly indestructible. Smack, swat, slam or smash it and the greenhead pauses (probably chuckles evilly to itself) and swoops in for the next round of attack. Oh and I haven’t even begun to discuss the painful bites nor the resulting huge welts.

At this point you’re probably thinking, “Ok, they sound pretty nasty but one or two flies isn’t the end of the world.” Ah, but we’re not talking about one or two flies! Scientists at Rutgers University have collected over 1000 greenhead flies PER HOUR all seeking a “blood meal.” (shudder) If that number doesn’t give you nightmares then imagine my panic when greenheads even attempted to fly down my snorkel in their quest for blood! This is the stuff of horror movies folks yet wetlands scientists persist, nay even thrive, in such an environment. Perhaps the greenhead has met its match?

I’ve done field work all over this country and have encountered numerous creepy crawlies. Heck, I once even had an alligator try to bite a fish trap out of my hand yet greenhead flies stand out. And yet, when reflecting on my many wetland adventures, do I mostly remember the beauty and complexity of the estuary right down to that unique marshy smell (malodorous to some and perfume to others)? Absolutely. Did I tolerate greenheads because my fascination with wetlands overrode my seemingly genetically programmed response to flail my arms around while screaming and swatting? Absolutely. Would I do it all again? Absolutely!

Wetland field stories…if you’ve got ‘em, I’d love to hear ‘em!

Environmental Leadership on Tribal Lands

Thursday, May 21st, 2009

Go to EPA's Science Month pageAbout the author: Sara Jacobs recently celebrated her 10th year working at EPA Region 9. She has spent most of her years in the Drinking Water Office, but is currently on a detail to the Superfund Division, working with the Navajo EPA.

When I saw that Lenore Lamb had been chosen as one of the EPA Pacific Southwest Environmental Award Winners, I was thrilled since I know first hand of Lenore’s accomplishments as the Environmental Director for the Pala Band of Mission Indians. I met Lenore in 2001 and three wells, three kids (two were mine), and eight years later, I have seen Lenore grow from a one woman show to managing a staff of 12. She’s gone from a young, eager environmental learner to an expert and leader in her field. Her efficiency and energy amazes me and I get the impression that she does the work of three people. (She tells me it’s due to large quantities of caffeine.)

Here are just some of her contributions:

  • Providing safe drinking water and wastewater disposal for both the Pala Band as well as a tribal community in Mexico by securing funding and overseeing infrastructure projects.
  • Developing a “Green Team,” with representatives from the Pala Casino Resort and Spa, that has implemented energy and water efficiency programs and diverted 170 tons of solid waste since implementation of their program last year.
  • Active involvement in the Upper San Luis Rey Resource Conservation District. Lenore has been instrumental in the clean up of illegal dumpsites along the creek beds within the reservation boundaries.
  • Supporting education and outreach programs through annual earth day events, tribal publications, exercises for the Pala Boys and Girls Science Club, and by developing a “Creating and Managing Tribal Transfer Stations” course.
  • Securing tribal funding and overseeing design and construction of a transfer station. The facility is open to the public, includes electronic waste collection, a green waste and composting program, a secured hazardous waste collection location, a state certified buy back center for recyclables, and a used oil collection program.

From my own experience working with tribes, I know that tribal environmental managers face enormous challenges. I’m even more impressed by Lenore since her accomplishments are more forward thinking than many non-tribal governments, even in a state like California, which is often on the cutting edge. Lenore has not only made significant contributions to improving the environment at Pala, she has contributed to improving environmental conditions throughout Indian Country.

Blogging from the Bog: How Healthy are the Nation’s Wetlands?

Tuesday, May 19th, 2009

Go to EPA's Science Month pageAbout the author: Michael Scozzafava has been with EPA since 2004 and the Office of Wetlands, Oceans, and Watersheds since 2006. He is project lead for the 2011 National Wetland Condition Assessment and chair of the National Wetlands Monitoring and Assessment Work Group (NWMAWG).

How healthy are the nation’s wetlands? Existing data sources make it almost impossible to answer this question with any confidence. The most recent Water Quality Report to Congress provided data for only 1.5% of wetlands nationwide. The U.S. Fish and Wildlife Service (FWS) Wetlands Status and Trends Reports provide invaluable information on the amount of wetlands (quantity), but are not designed to assess overall wetland health (quality).

It is vitally important that we answer this fundamental question to effectively plan wetland protection and restoration efforts. Currently, we don’t know if we’re using resources wisely or focusing work in areas that need the most help. We can’t identify the most common wetland threats and develop strategies to reduce those threats. The U.S. FWS documented that the country is gaining 32,000 wetland acres each year, but the data suggests we may be increasing the number of low quality wetlands that provide only one service (like storing excess rain water) and losing high quality wetlands that provide a range of services. So, although we’re increasing the total number of wetlands, we’re probably losing natural filtration for our drinking water, protection from coastal storm surges, habitat for birds and wildlife, and nursery grounds for fishes. We need to better understand the nature of wetland gains and losses, identify the types of wetlands that are especially at risk, and implement policies to reverse trends of wetland degradation.

EPA will collaborate with states, tribes, and other federal agencies to implement a field-based survey of the nation’s wetlands in 2011. We will sample about 900 randomly-selected sites using standard monitoring protocols that characterize the plants, algae, soils, and relative wetness of each sampling location. We will also test for high concentrations of chemicals and search for evidence of human and natural impacts at each site. In 2013, we will combine all of this information to produce a baseline assessment that reports the overall health of the nation’s wetlands and identifies the most common wetland threats.

It is crucial that the results of this assessment are used by decision makers to improve how wetlands are managed, restored, and protected. EPA has considered many possibilities for how the information might be used, but certainly have not identified every opportunity. So the question to decision-makers, wetland managers, and the general public is: what information can EPA provide to help you protect wetland resources?

Pacific Institute Water Policy Catalysts Flooded with Environmental Award Praise

Thursday, May 14th, 2009

About the author: Timonie Hood has worked on EPA Region 9’s Resource Conservation Team in for 10 years and is Co-Chair of EPA’s Green Building Workgroup.

Water supplies and management have long been a hot topic out west, and the Pacific Institute, an EPA Pacific Southwest Region Environmental Award winner has done incredible work to develop sustainable water policy.

Agriculture accounts for 80% of California Delta water consumption, and in 2008, drought and legally mandated water pumping restrictions resulted in farm losses that were estimated as high as $245 million by mid-summer.

Click on the Report cover above to read the report.

In 2008, a Pacific Institute report, “More with Less: Agricultural Water Conservation and Efficiency in California - A Special Focus on the Delta,” altered the approach to California’s water crisis. The researchers found potential water savings in the agricultural sector can reach 0.6-3.4 million acre feet of water—the equivalent of 3 to 20 new dams–without harming agricultural production or the economy.

This work has been catalytic—creating discussion around non-infrastructure oriented solutions that have long been absent from water policy discussions in California.

The Pacific Institute project team - Heather Cooley, Juliet Christian-Smith, and Peter Gleick -did much more than stimulate discussion, they influenced decision making processes with sound science, met with the California Board of Food and Agriculture and the Governor’s Delta Vision Blue Ribbon Task Force, and briefed more than 60 State legislators and staff.

The Pacific Institute’s leadership has changed the search for water solutions from physical answers—more dams, more reservoirs, and more conveyance—to the better management of the vital resources we do have to ensure a safe, reliable water supply in the face of a growing population, increasing threats of climate change, and environmental degradation.

Read the Report - it’s as refreshing as a cool glass of water!

Clean Out the Chemicals

Friday, May 8th, 2009

About the author: Jeff Maurer manages Web content and does communications work for the Office of Solid Waste and Emergency Response.

When my mom first starting teaching in 1971, duck-and-cover drills – in which students were taught to curl up underneath their desks in the event of a nuclear attack – were still in vogue. Apparently, desks were much sturdier back then – strong enough to withstand a nuclear blast.

When we lived in Kentucky, Mom taught at a school that practiced regular tornado drills. By the 1990s, teachers were being taught how to treat cuts in ways that prevent the spread of hepatitis and HIV, and “lockdown” drills became common after the Columbine shootings. By the time Mom retired last year, school safety training had been expanded to include managing students’ gluten, seafood, and peanut allergies.

Clearly, student safety in schools came a long way during Mom’s career. But in all of her years as a teacher, my mom was never once taught how to safely manage chemicals that are commonly found in schools.

That needs to change. School science labs, trade shops, and janitorial areas – any area of a school – can contain hazardous chemicals that can be harmful to students and teachers if improperly managed. Beyond the obvious health hazards, chemical spills can result in lost school days, cleanup costs, and liability.

Chemical management should be part of every school’s safety routine. Thankfully, EPA’s Schools Chemical Cleanout Campaign (SC3) is making it easy for schools to clear out unneeded chemicals and make sure that needed chemicals are properly managed. The SC3 provides a wealth of resources – including a promotional video and a tool kit for starting a chemical management campaign – to teachers, parents, school administrators, community groups, and just about anyone concerned with safe chemical management in schools.

It works, too; schools across the country are implementing successful chemical management campaigns. In my area, the Arlington Public Schools system removed 600 pounds of chemicals from its secondary schools. That hits home for me because my sister – following in Mom’s footsteps – works in the public school system here in Northern Virginia.

For my sister’s safety and for everyone’s safety, I’m glad that safe chemical management in schools is catching on. This week is Teacher Appreciation Week; I think that a good way to celebrate might be to see if the schools in your area are practicing safe chemical management. After all, the danger posed by hazardous chemicals, unlike certain other safety concerns, can’t be neutralized by simply hiding beneath a desk.

Fix A Leak: Fix Leaks, Save Water & Money

Thursday, March 19th, 2009

About the author: Steve Burton* the SW territory contact for Ferguson Enterprises, Inc.’s Private Label Program. Ferguson is the EPA’s 2008 WaterSense Retailer/Distributor Partner of the Year.

We have a two-person household in an average-size home in Oro Valley, Arizona. In November 2008 we discovered the guest bathroom had a slow internal leak caused by an aging fill valve inside the toilet tank. The only reason we thought to look for a leak was the spike in our water bill that month.

We found a slow leak inside the toilet tank in our hall bathroom. The noise was faint. If the fan was on or if you were not directly in the bathroom, you could not tell there was a noise coming from the toilet tank.

The impact this one slow leak had on our water usage/bill during November 2008 is below.

  • Sept 2008 $41.97
  • Oct 2008 $51.33
  • Nov 2008 $148.30
  • Dec 2008 $58.66
  • Jan 2008 $33.64

This drove home how important it is to check/maintain water fixtures in our home to conserve water and save money. For about $15, we were able to fix a leak that was costing us $100 a month!

Fix a Leak: Detecting and Fixing Toilet Leaks

Tuesday, March 17th, 2009
About the author: Ed Del Grande is host of “Ed the Plumber” on the DIY Network*, and regularly appears on HGTVPro.com as the plumbing expert. He writes a nationally syndicated column, “Ask the Plumber,” which appears in newspapers across the United States. Del Grande is a native of Rhode Island.

image of author, Ed Del Grande, kneeling next to a toiletHow do you know when a toilet is leaking? Faucets and showerheads will drip, which is a dead giveaway for a leak. But what about toilets?

Have you ever experienced your toilet “running” for a long time after a flush, or had to wiggle the handle to make it stop, or does it ever randomly “run” at night, even when nobody flushed it? A “running toilet” is a leaky toilet.

If you’re toilet is leaking, most likely it’s a bad flapper. If you look inside the tank, you’ll notice a ‘rubber stop’ at the bottom of the tank. This device is no longer creating a water-tight seal, and your toilet is leaking. To confirm, you can drop a couple drops of food coloring in the tank. If you see any food coloring leak into the bowl, your toilet is leaking.

You can purchase replacement parts for your toilet at any hardware store or home improvement center. This should stop the problem. And, these replacement kits are pretty easy to install.

However, if you’re taking the time to make this fix, you should check to see how many gallons your toilet uses with each flush. The federal mandate is 1.6 gpf, but if your house is old, or you haven’t remodeled in quite some time, chances are you have a toilet that uses 3.5 gpf or more. And that’s a waste of water - a waste of 2 gallons of fresh drinking water with every flush. If you have an old toilet, consider replacing it with a new, WaterSense labeled toilet. These new toilets don’t sacrifice design or performance.
