Collaboration is Key to Environmental Monitoring

Tuesday, August 18th, 2009

March 2009 marked a memorable month in the 19 years I have worked for EPA’s Office of Water. That is when Environmental Monitoring and Assessment published two articles about EPA’s National Lake Fish Tissue Study. I had the privilege of managing this study for the 8 years required to complete it.

It also included the largest set of chemicals (268) ever studied in fish. Field crews worked 4 years to collect fish samples from 500 lakes selected randomly from a statistically-defined set of about 147,000 lakes in the lower 48 states. Tony Olsen in EPA’s Office of Research and Development designed the study and directed statistical analysis of the concentration data. The design of this study generated results that allowed EPA to estimate the percentage of lakes and reservoirs across the country with fish tissue concentrations of specific chemicals, such as mercury, above levels of concern for human health.

Aside from my intense feeling of pride in providing leadership for this major scientific study, I look back in amazement at the number of people who volunteered years of effort to make this study possible. EPA relied on the participation of scientists from 58 state, tribal, and federal agencies for 5 years to evaluate sampling sites and collect fish samples. Their long-term commitment to maintaining the highest standards of quality while participating in the study produced scientific results that earned the praise of senior EPA managers, industry representatives, and members of academia. I want to extend my heartfelt appreciation to all of the scientists across the country that support EPA. In the end, it was their hard work and dedication that made this study a success.

Environmental Engineering in the Office of Water

Friday, August 14th, 2009

My sister once asked me to speak to her fifth-grade class on career day. All the kids raised their hands when I asked them if they thought it was important to protect the environment. However, they were stumped when I asked them if they knew what I do as an environmental engineer at EPA. To be fair, this is a difficult question, as environmental engineering is a relatively new profession and it includes topics from many other studies like biology, chemistry and hydrology. I told the class that my job is to collect, organize, and analyze data so that decisions can be made on how best to protect the environment. To be a little more specific for all of you who think you are smarter than a fifth grader, my job is to help establish technology-based regulations to control industrial wastewater discharges to sewage treatment plants and to lake and rivers.

To better explain how I use science to inform EPA’s decision-making, I described to my sister’s class how I use wastewater sampling, industry surveys, and visits to industrial facilities to gather the basic data to help identify the best available technologies for treating industrial wastewater. My colleagues and I sample industrial wastewater to identify pollutants in the wastewater and to quantify the amount of pollution. Industry surveys help us identify available and affordable best management practices and technologies to reduce and treat industrial wastewater. Finally, visits to industrial facilities help us learn more from industry experts on how to better reduce and control industrial wastewater pollution. I use the data we collect and my engineering skills to identify the capabilities of different technologies to treat industrial wastewater and the related costs and pollutant reduction benefits. For example, some wastewater technologies like reverse osmosis can produce very clean water but certain pollutants must be removed prior to their treatment by reverse osmosis. The industry data we collect (wastewater sampling, industry surveys, site visits) help me identify how to configure different wastewater treatment technologies for the different wastewaters across all industry sectors for EPA’s studies and regulations.

One of my favorite site visits involved taking a helicopter to an offshore oil and gas platform in the Gulf of Mexico. I went to this platform to see how they reduced their discharges of drill cuttings, the small bits of rock excavated by the well drilling, through use of newer and better technology. I gathered the information from this site visit and other data to establish a new rule to control the amount and types of wastes that can be discharged from offshore oil and gas platforms. We estimate that industry’s compliance with our new rule reduced the annual discharge of drill cuttings by 118 million pounds! Numbers like that helped my sister’s students understand how I use science and engineering to help protect the environment. And by the end of my career day talk, all the kids thought my job wasn’t so boring after all, as I get to visit interesting places, meet people from all over the country, and occasionally do cool things while protecting the environment.

Clean Water Enforcement Action Plan

Friday, August 7th, 2009

On July 2, 2009, Administrator Lisa Jackson asked me, as the head of EPA’s enforcement and compliance program, to examine our water enforcement program in light of information showing that water quality goals are not being met and that there are too many violations in too many places. She asked me to report back in ninety days with recommendations to improve transparency, strengthen clean water enforcement performance, and expand our use of technology to increase efficiency and to provide useful information to the public. Our recommended action plan needs to improve compliance and address the problems that are having the biggest impact on water quality.

To help us achieve the Administrator’s goals, we invite you to share your ideas through our discussion forum. The blog can be found at http://blog.epa.gov/cwaactionplan Your ideas will be considered for recommendations to the EPA Administrator about the future direction for EPA’s water enforcement program. In all our discussions, EPA will be mindful of the need to focus on the most important work for protecting water quality and improving compliance with the Clean Water Act, given resource constraints that require us to place a premium on innovation and efficiency.

OSV BOLD – Day 3 – August 1

Tuesday, August 4th, 2009

Day 3 – August 1, 2009

03:30 a.m. my alarm goes off. It didn’t take much to wake up as the rolling waves had me sleeping a little lighter last night. At 03:48 I rolled myself out of bed and had to do a bit of a balancing dance to stay upright, get dressed, and not wake up Kate.

As I entered the wet lab to greet the departing team and my group, I could tell the Bold was hauling its way to the next offshore station. The staff and crew hadn’t slowed down for a minute all night long.

We were headed “down East” as they say, up along the outer reaches of Penobscot Bay in northern Maine to station R1 -14, about 30 more minutes. Shifts have been light on the sampling as we’re working our way through the outer points which are fewer and far between. In a day or so we’ll be turning around to work our way down closer to shore, where the work will really pick up.

I found out that the last team had done another plankton tow for our budding marine scientists in New Bedford, MA around midnight. I wonder if they caught anything good? Chief scientist Matt Liebman says that the zooplankton tend to move up in the water column at night, whereas during the day they tend to trade places with the phytoplankton which relies on more sunlight.

Speaking of sunlight, it seemed to come up quickly. Though I have to admit I enjoyed the hour or so of darkness on the deck, it felt a bit special knowing we were doing this work round the clock. We all feel it’s incredibly important to study the water that seemingly is far away from the influence of human activity, sadly though we’re finding that it’s not the case. By gathering this data far offshore, we can compare it to the health nearer to the coastline. It is our hope that in future years we can come back and do the same sampling to see if conditions are improving or getting worse. Perhaps you’ll be doing this very same work someday!

At 04:37 we arrived on station, and we were told the water was about 470 feet deep! We deployed the CTD and rosette water sampler, everything went smoothly. I noticed the water I was bottling from the very bottom was freezing! Now might be a good time to explain that we’re taking water samples from three parts of the water column, the bottom, the middle and the surface. I’ll explain more tomorrow about what we’re looking for to determine where these levels are. Each of the three batches though is filtered to catch the chlorophyll, which we carefully contain for analysis at our lab in Chelmsford, MA.

We processed the samples as we took off for station R1-10, about a 5 hour haul away, even further north. To help the next team we cleaned the lab and labeled some extra bottles, I headed to the bridge to get some photos of the rising sun. Once I got there, I promptly decided I wasn’t going to miss another sunrise on this trip.

At 06:10 I sat up on the bridge with Derek, ordinary seaman and Doug, third mate, to record our latest data results from yesterday and this morning. They told me we were approximately 26 miles offshore and wouldn’t have an internet signal until this afternoon. Today’s sampling work will consist of a lot of offshore stations, fewer and further between. Sorry guys! Technology still can’t help us when we’re this far away. In between writing my eyes were peeled on the horizon for those telltale water spouts…

06:21 Doug and Derek, turned on the weather report for Captain Jere as he settled in his chair with a fresh cup of coffee. At 07:00 I went to wake my roomie, her shift was starting in an hour. I also figured it was a good time to take some sea sick meds to be on the safe side. We were rockin’ and rollin quite a bit, even though the seas were relatively calm, the swells were wide.

Before I knew it, I had zonked out with my jacket still on, but awoke to a gentle knock on my door. Even in my groggy state I knew it could only mean one thing! My team leader Ed had come down from the bridge to tell me that First Mate Doug had spotted a spout!
I didn’t even tie my shoes (don’t try this at home), and ran up the stairs using the walls and handrails because I wasn’t totally awake yet. Once I reached the bridge I squinted my eyes onto the horizon and sure enough, about 200 yards off the bow on the starboard side I saw the little, white puff of mist from the whale’s blow hole! I got some pictures and used my zoom lens as binoculars. We watched his dorsal fin come up and then disappear into the deep blue. While it was only a glimpse into this whale’s solitary travels, I hope it’s a sign of more to come today!

That was my first time seeing a whale in the Atlantic Ocean, and after consulting a whale identification book with Doug and Ed, we are fairly positive it was a Common Minke Whale, judging by the shape of the dorsal fin and even the shape of the spout cloud. Not all misty spout clouds are the same!

It’s a little past 1000 now, and I’m up on the “steel beach” as Captain Jere fondly calls it. The sun is bright, we seem to be able to see forever to the horizon. Now I can understand why so many early explorers thought the Earth was flat! Did you know that? Believe it or not it took humans a while to figure out that the Earth is round, and because of this you can’t see the other side of the ocean, it curves around very, very, gradually, which is one of the reasons you can’t see the other side.

Fellow EPA staffer Regina Lyons just joined me, and we traded stories of “sightings” today. Whereas I had been lucky enough to see a Minke whale, she said that as she was leaning over the side of the boat watching the waves, she saw four balloons go by in 20 minutes. Wonder how those got out here? It’s so pristine you’d never expect it, but balloons can travel hundreds of miles in the air before they fall back down. These ones were white and silver mylar, maybe they came from a birthday party or a wedding? We were going too fast to grab them, and it sadly tells another story about the ocean these days. We shouldn’t see garbage and plastics out here, especially in an area off northern Maine where less people live. Regina said they had started to degrade a little bit, but usually the bits of garbage just break into smaller pieces, especially plastics. They never really go away.
More on the rest of my day later! ~ Jeanethe, “aspiring Second Mate”

OSV BOLD:Day 1 - July 30th – Wrap Up

Friday, July 31st, 2009

The sun set around 7:45, and my first shift began! Sporting a bright orange vest and hard hat, my team helped to deploy the CTD off the starboard side of the BOLD just off Cape Ann in Gloucester, MA.

In this first day (and a half day at that) we were able to sample 7 stations!  Chlorophyll samples are being sent to EPA New England’s laboratory on land in Chelmsford, MA.

Stations labeled “R1…” are located on the Captain’s Log page. New Stations have the latitude and longitude.

At a bit past midnight, my shift ended and we were on course to New Hampshire’s coast. Said, “hello and goodnight” to my roomie who caught the tough shift, she will get back to the room around 4 am.

I wonder what tomorrow will bring!
