The Lower Raritan Watershed Partnership and Rutgers Cooperative Extension of Middlesex County run a volunteer pathogens monitoring program from May to September every Summer. On Thursdays we collect water quality samples at 6 non-bathing public access beaches along the Raritan River, and report the results on Friday afternoons. This week, water quality tests show pathogens levels below EPA federal water quality standards all of our sites! Pathogens/Enterococci “colony forming units” (CFUs) are measured and used as indicators of the possible presence of disease-causing bacteria in recreational waters. Suitable levels for primary contact should not exceed 104 cfu/100mL. Although our results show pathogen levels under federal water quality standards for cleaner levels of water, please recreate on the river at your own risk and always be sure to wash your hands. Pathogens may pose health risks to people fishing and swimming in a water body. More information about our pathogens program is on our water quality monitoring webpage.
We’d also like to share a new map we’ve been working on to help improve the understanding of the water flow through the watershed. In the coming weeks, we will be integrating our bacteria findings into our new map. Special thanks to Brenda Allen for developing the map and providing this “sneak preview”.

Many thanks to the Rutgers Cooperative Extension of Middlesex County and Interstate Environmental Commission for their partnership, and to our monitoring volunteers!
I know a forgotten place where some of New Jersey’s purest cool water springs from deep underground. And now it may be threatened.
This spring water generously flows from a small but verdant wetland along a streambed of glacial sand with barely a ripple. You won’t find this place on modern maps unless you know where to look. Its existence, however, was well known to Leni Lenape families who lived in the adjacent forests for perhaps thousands of years. They called this now forgotten place “great spring.” They called the stream “gentle flowing.”
The Black River as it flows from the Great Spring. This photo is of the Raritan Headwaters Association stream monitoring site approximately 700 feet downstream from the Hercules property. The volume of water from the spring is 11.52* cubic feet per second or over two-billion gallons per year.
The Great Spring and its waters were also well known to the first European settlers in the Succasunna Valley. According to written accounts from the 1700s, folks marveled at the constant flow even during dry spells. The water was described as always cool and delicious. In what may have been a translation error back then, the early settlers called this stream the Black River. The actual Lenape name for this gentle flowing stream was “Alamatong” from which we get its modern name, the Lamington. While most everyone knows of the Black River or the Lamington River, the spring itself has faded from memory and disappeared from our maps. So, what the Native Americans knew, and most of us don’t, is that the Great Spring is literally the fountainhead of the North Branch of the Raritan River.
So where is this environmentally important spring? It is at the Southernmost edge of the former Hercules Powder property along U.S. Route 46 in Kenvil, New Jersey. You drove past it without notice if you ever traveled on Route 46 in Roxbury between Mine Hill and Ledgewood. Its outlet is literally across the highway from an IHOP Restaurant.
And why is the Great Spring a forgotten place? For over 150 years the spring has been an inconvenient appendage on 1,000 acres of privately owned industrial land where TNT and other explosives were manufactured. The spring’s wetlands have remained off-limits to the public and its ecology and geology have never been properly studied. A review of the New Jersey Highlands Environmental Inventory from 2013 suggests that the spring was not explicitly considered. And while everyone knows the former Hercules Powder property is a major pollution site, there is little public information on the extent of the contamination or the threats it may pose to the spring or the important aquifer below from which this water rises.
We do know that the now-abandoned Hercules property is laden with toxic chemical waste products from its bygone manufacturing days. We know there are acres of soil laced with PCBs, the by-product of burning chemical waste and other debris on-site. We know that the toxic chemicals used in the manufacturing of explosives still remain in some pipelines which run under buildings that haven’t been demolished yet. We know that some of these chemicals have contaminated the surrounding soil to an unknown extent and that these contaminants have migrated over the land and polluted surface waters in other places around the country where TNT was manufactured. Most of these sites, including several former Hercules plants in New York, New Jersey, California, and elsewhere, are designated superfund sites.
This Hercules property would qualify as a superfund site, but that was not the option the New Jersey DEP chose. In 2009, the Site Remediation Reform Act gave the DEP the power to allow private corporations to conduct all remedial activity on contaminated sites in New Jersey under the Department’s scrutiny. The State also created Licensed Site Remediation Professionals (LSRP) to assure the work is completed under DEP guidelines. Under this arrangement, Ashland Global Properties, who bought the Hercules tract after the company went out of business, hired the WSP Corporation to conduct the cleanup back in the 1970s. The work was begun but never completed. The LSRP responsible for the cleanup recently changed hands and a new company is now in charge of the work. Activity on the site is back underway.
In the decades since Hercules shut down, public awareness of the pollution on the site and progress in cleaning it up has faded. Few know that the underground aquifer and spring that surfaces on the Hercules site is the source of the Black River, an important link in the Raritan River system that provides drinking water for 1.8 million people. Numerous commercial well fields also tap this same aquifer to supply municipal drinking water to many towns in the region.

This juxtaposition of the Great Spring wetlands, a precious natural resource, and the massively contaminated Hercules site, a commercially valuable property, is bound to create competing interests. Roxbury Township officials would like this site safety cleaned up. They are understandably eager to restore the site for future development. This is the largest undeveloped land left in Morris County and it is close to major rail and highway transportation hubs. Environmentalists would love to see the wetlands and surrounding rainwater recharge areas on the property protected and preserved.
Since November of 2021, the remediation process accelerated under a new corporation and the new LSRP. The Roxbury Planning Board approved two work permits, and earth moving equipment is on-site taking down trees, removing PCB contaminated soil, and bringing in clean fill to replace it. A bioremediation staging area is being built where other chemically contaminated soil will be brought and be microbially composted. The soil will be held in six large “pods” and seeded with a bacterium that breaks down the chemical components of TNT. The process is expected to take about six years.
A map showing the location of the soil remediation pods was presented at a public meeting in Roxbury last November. Of the more than 800 acres of land on which these bioremediation pods could be located, the map appears to show the staging area directly beside the Great Spring wetlands. The rationale for this decision or any mention of the spring was apparently not discussed at the meeting.

Local environmentalists and freshwater advocacy groups familiar with the Hercules tract are anxious to learn more. If chemical toxins on this site leach into the surface water at the spring or seep into the aquifer below, the water supply for 1.8 million people could be in jeopardy. Recent activity on the site has come to the attention of the Raritan Headwaters Association (RHA), which monitors water quality within the upper Raritan River watershed. RHA has begun collecting information to independently assess environmental concerns. The lack of public information about cleanup operations and the low level of public awareness about the threat to water supplies is a worrisome combination.
(4/17/22 Addendum)
The Question: The Great Spring contributes 2.2 billion gallons* of water a year to the Raritan River, which in turn serves the water needs of 1.8 million people downstream. The presence of toxic soil on the same land from which flows the Black River begs the question: Is it wise to bring the most contaminated soil on the property to a bioremediation site at the edge of this spring?
The Lower Raritan Watershed Partnership and Rutgers Cooperative Extension of Middlesex County run a volunteer pathogens monitoring program from May to September every Summer. On Thursdays we collect water quality samples at 6 non-bathing public access beaches along the Raritan River, and report the results on Friday afternoons. See here for more information on our pathogens monitoring program.
Our monitoring results for June 16, 2022 are somewhat better than previous weeks, however we received about ½ an inch of rain while we were out in the field doing the sampling, which means that bacteria levels are most likely higher than test results indicate.
Enterococci results are reported in Colony Forming Units or CFUs. Suitable levels for primary contact activities (directly touching the water) should not exceed 104 cfu/100mL. Pathogens/Enterococci levels are used as indicators of the possible presence of disease-causing bacteria in recreational waters. Water samples taken at sites with green “smiley faces” are below federal Environmental Protection Agency (EPA) threshold for Enterococcus. Water samples taken at sites indicated with red “smiley faces” were above federal EPA threshold for Enterococcus and suggest potential health risks from pathogens. Pathogens may pose health risks to people fishing and swimming in a water body. Sources of bacteria include Combined Sewer Overflows (CSOs), improperly functioning wastewater treatment plants, stormwater runoff, leaking septic systems, animal carcasses, and runoff from manure storage areas. Please enjoy our waterways at your own risk!
Big thanks to our partners, Rutgers Cooperative Extension of Middlesex County and Interstate Environmental Commission, and to this week’s monitoring team Frank Dahl and Andrew Gehman, and of course to our Monitoring Outreach Coordinator Jocelyn Palomino.
With 0.83 inches of rain on Thursday morning June 9, you can probably guess the water quality vibes! High Enterococcus levels at almost all our pathogens monitoring sites this week (read about the exception below) means Raritan River lovers should be wary of engaging in waterfront activities this weekend.
Our Perth Amboy site was especially gross. Water Quality monitoring after heavy rains near combined sewer overflows (CSOs) is never pleasant. Look closely at the waterline in the photo below. What you see is several inches of pulverized toilet paper, disposable wipes, and poo defining the water’s edge at our 2nd Street Park Perth Amboy site. There was active discharge of sanitary sewage from the CSO, the pipe in the middle right of the image. Any guesses as to the dominant odors?

Despite the yuck factor, it was a GORGEOUS day to get out for some sampling. Huge thanks to our crackerjack team including the LRWP’s Community Outreach Project Manager Jocelyn Palomino, and our volunteer monitors Andrew and Frank pictured below.

Moorestown Friend School Senior Emma Nei joins the LRWP as a 2022 Summer Intern. Here she shares her impressions of her first day “on the job” – conducting outreach for the LRWP at Rutgers Day.
This past weekend, I experienced my first day interning for the Lower Raritan Watershed Partnership and my first Rutgers Day, a day dedicated to showcasing the different programs, events, and culture of the Rutgers community. RU is my mother’s alma mater and she explained the excitement around this day and how thrilled she would be to run into past professors and classmates. We parked the car and made our way to find the LRWP table. I was struck by the smells coming from food trucks and the sounds of tents and tables being set up. Thankfully, it was beautiful outside. With the sun shining through the trees and a nice breeze on my neck, I knew I would enjoy the day. Surrounding the water body known by students as Passion Puddle, there were dozens and dozens of displays for many different organizations. You could measure how high you could jump at the Kinesiology Department’s table or play trivia games with the State Climatologist. After a few minutes of walking, a large rain barrel and a colorful sign captured my attention. I had arrived at my destination.
Jocelyn and Piash, two other interns for the LRWP, quickly showed me the ropes. I had already done some background research on the watershed but they taught me the best ways to catch peoples’ attention as they walked by, answer their questions and introduce some of the programs LRWP offers. Soon I was explaining the basics of the water monitoring program, how samples are taken every week from six different locations along the Raritan and where to find the results posted online. I answered questions as best I could but when someone asked about green infrastructure in their town, Jocelyn and Piash were both there to swoop in and help.
I loved my environmental science classes this past year. I knew I was interested in science and research from the projects I had done throughout high school. Wrapping up my senior year through internship is an exciting way to learn something new and gain some work experience before heading off to college. Classes end in April at my high school and students are required to intern for an organization of their choosing during the month of May. After going through a list of environmental non-profits, my mother suggested looking at the LRWP. Their website and newsletters really conveyed the mission, purpose and passion of the organization and I wanted to experience it. My interest in the health of local waterways increased as I saw the wide range of programs offered.
As the hours of Rutgers Day passed, all sorts of people came up to our display to ask about specific projects. Engineering students wondered how bad the pollution was in various waterways. An outdoorsy couple approached, wondering about the best times to go kayaking or hiking around the Raritan River. Children wandered up to look at the plastic bugs on the table, their curiosity piqued. It became obvious to me that the health of local waterways impacts the whole community; no matter how old you are or what your background is, you are affected in some way. So many different people stopped at the table and shared their concerns about the health of their waterways. We were able to provide ways for them to learn more, to help monitor them and to actually help clean them. A mother came to the table with her two boys who were fascinated by the critters on the table. She was curious about how safe the waterways were because her son liked to collect rocks by the river. She also wanted to learn if she and her family could come out and volunteer. I realized that LRWP wasn’t just a means to collect data and inform people about issues but also a way to bring the local community together through service. As my day wrapped up, I said goodbye to some new friends and felt excited to start my internship.
Imagine a colorful fleet of canoes and kayaks gathered at the confluence of the north and south branch in anticipation of the start of a dash down the Raritan River to the sea. Described as a sojourn, dash, race and tour to accommodate all levels of experience, the finish lines for each class can be a different take out along the way. Classes for racers, timed for placement and simply celebration upon reaching any chosen finish line for the touring dashers. Distance or time become the personal feedback for participants who may wish to improve their last year’s performance. In that way the ‘race’ has the elements of developing into a tradition where dad’s and daughters, moms and sons, look forward to next year and maybe in anticipation, focus on improving their health and physical conditioning.
The paddler’s intimacy with the Raritan brings with it a deeper appreciation of the river, which has existed as more of a concept to most people who may only glimpse it at a distance, while passing over a bridge on the way to work. With intimacy comes consideration and concern about all things impacting the river and its watershed.
The possibilities to grow a network of support for the treasure that is the Raritan River, are limited only by imagination. Photographs and art work inspired by the river’s appearance through the seasons could be celebrated by riverside towns, restaurants, schools and galleries to be dispersed far and wide. Like seeds in the wind, the beauty and appreciation of the Raritan may be an inspiration to awaken distant communities to the riverine treasures in their backyard.
One example of a successful effort to market a once polluted river, is the Kenduskeag Stream Canoe Race, held each April, in Maine. At one time salmon and eels returned from the sea via the Penobscot River to the Kenduskeag stream. By the time Thoreau walked he shores of the Kenduskeag in the mid 19th century, tanneries and flour mills blocked and poisoned the stream and continued well into the 1960s. A group of local canoeists came up with the idea for a canoe race to showcase the Kenduskeag and bring attention to its health. Eventually the race expanded to be televised and enjoyed by hundreds of viewers and attendees. The salmon run is making a comeback and even Sports Illustrated found room on its cover to celebrate the longest early season canoe race in New England. I participated in this race for eighteen years and carried the seeds of inspiration back to the Raritan. It is no small coincidence that Henry David Thoreau left indelible footprints along the Raritan River and the Kenduskeag for future generations to follow.
The crowd of streamside supporters bundled dry and warm, cheer on canoeists who await the countdown for the start of the Kenduskeag Stream Race. The countdown to the start of the race, 5. 4. 3. 2. 1.gets the adrenaline flowing. This is a scenario that may someday be played out at the confluence of the Raritan River.

Throughout 2021, I volunteered with the LRWP to build a wooden boat—a long, narrow rowing shell–destined for use on the Raritan River. During the pandemic, this boat building project was like a good dream. While I spent weekdays working remotely, Saturdays with the boat project meant the smell of cedar, the roar of the power planer, the feeling of smoothly sanded wood, and being with other people. One year later, I decided to live that dream by pursuing carpentry and wooden boat building through a program called The Carpenter’s Boat Shop, located in mid-coast Maine.
Essay author Sarah Tomasello (right) and Amber Hennes volunteered as paddle build leads for the LRWP’s 2021 boat build project
Like many volunteers working on the rowing shell with the LRWP, I began with minimal experience. Our workshop was a hands-on classroom where other volunteers generously shared their skills. With this support I quickly gained more experience and confidence. Along the way I discovered that I liked nothing more than being in a workshop environment, making things with wood and tools, teaming with others to solve problems, and getting caked in sawdust.
This past February, I drove up to Maine and entered the 4-month long Carpenter’s Boat Shop program, where I am continuing to learn how to build small wooden boats. This program resembles the LRWP boat build project in that it is centered around building a community and sharing skills. At the Boat Shop, I live and work alongside a group of eight other apprentices, sharing chores, cooking meals, going for hikes along the coast, and building a type of row boat called the Monhegan skiff.
Working on a Monhegan skiff at the Carpenter’s Boat Shop in Maine
The Monhegan skiff is an historic vessel in this region that is still used by the residents of nearby Monhegan Island. Once used primarily by fishermen, the Monhegan skiff was designed to safely navigate the rolling ocean waters around the island and transport fishermen between the shore and their workboats. The skiffs are still purchased for this purpose. The neighbors who frequently visit the Boat Shop campus may have ties to Monhegan Island or have worked as boatbuilders in the region. It is not uncommon to see old wooden boats—restoration projects in progress—sitting in front yards. It is inspiring to be in a place where there is a palpable sense of history and connection with the natural environment. The craft of building small wooden boats weaves these things together.
Being part of this community in Maine makes me excited about what wooden boats can do for the Raritan region. Building the rowing shell with the LRWP helped me see the history and beauty of the Raritan River, Raritan Bay, and nearby waterways. Bringing a community together to build small, well-crafted boats builds a culture of connection with local waterways, local history, and between neighbors, hopefully leading to increased stewardship and recreational access to the Raritan.
Since Summer 2019 the Lower Raritan Watershed Partnership and Rutgers Cooperative Extension of Middlesex County have conducted pathogens monitoring for Fecal Coliform and Enterococcus at six non-swimming public beach access sites along the Lower Raritan during the warmer months.
In this video, filmed as part of a public outreach session on 3.24.2022, we present a summary of data and findings for 2019-2021 monitoring, including analysis results of genetic source. We also share information about our monitoring plans for Summer 2022, including our partnership with the EPA.
The New Jersey State Department of Environmental Protection (NJDEP) is currently conducting the 2022 Clean Watersheds Needs Survey (or CWNS). The LRWP encourages all Lower Raritan communities to participate so as to collect information about wastewater infrastructure, stormwater – grey and green infrastructure, and non-point source pollution control projects, including the needs for decentralized wastewater (or septic) systems.
The U.S. Environmental Protection Agency (USEPA), in partnership with the State of New Jersey and other states, surveys communities every four years to identify any water quality or public health-based capital needs (up to 20 years) and costs in your community. The results are published in a Report to Congress, and it is used by Congress and state legislatures in their budgeting efforts.
The CWNS data are also used to help measure environmental progress, contribute to academic research, provide information to the public, and help local and state governments implement water quality programs. This data can influence the allocation of SRF funds and future special federal grants or funding programs. The CWNS is your best opportunity to let our decision-makers better understand the financial challenges you face in implementing your wastewater, stormwater management, and NPS pollution control programs.
To participate in the survey, first identify any water quality or public health-based capital needs (up to 20 years) and costs in your community that were not funded by January 1, 2022. Then, submit these community needs by completing the online survey form and uploading any supporting documentation describing your community’s new needs and costs.

On March 21 we welcome the first day of Spring in the northern hemisphere. Most of us learn in elementary school that as the Earth rotates on its axis, the tilt of rotation brings the northern and southern poles either closer to or farther from the sun. In the farther position each hemisphere experiences less daylight, and the days are cooler. In the closer position – hello Spring! hello Summer! – more concentrated sunlight results in warmer days and longer periods of daylight.
Our relationship to the sun also affects the night sky, and the visible constellations are seasonal and change throughout the year. If you make a habit of looking at the sky every morning just before sunrise or every night right after sunset, you will start to notice how a few new stars emerge in the east each day. Since the sun and stars move at different rates, the change you observe is what is revealed with a gradual tilt of the earth’s axis at approximately one degree per day.
One thing that doesn’t change while the earth moves on it’s axis is the latitude, or north–south position, of specific points or locations on the Earth’s surface. New Jersey’s Liberty Science Center explains: “The key factor determining which stars we can see on a certain night is our latitude. Latitude is how far we are north or south of the equator.”
Our Raritan Watershed is 40 degrees north of the equator. Other 40th latitude cities include Menorca, Sardinia, Beijing, Humboldt County, Boulder and, closer to home, Philadelphia. Per the 1894 Kansas-Nebraska Act, the 40th parallel north also forms the boundary between the states of Kansas and Nebraska. Anyone at the 40th parallel looking up at the night sky at the same time of night will see the same stars that we do in our Lower Raritan.
As fascinating as looking at the night sky is as a way to track seasonal change, of course there are other ways to use our position in space to perceive the passage of time. Instead of looking up at the stars at night we can observe the change in shadows on our landscape. As the Earth rotates towards the sun, the sun gets closer to the zenith, or its directly overhead position. This affects the cast of shadows on the landscape around us.
Use Spring Equinox to start investigating the interplay of sun and shadow on the landscape.
Photo taken in Rutgers EcoPreserve at approximately 2pm February 20, 2022.
The photographer Henri Cartier-Bresson wrote “To take photographs means… putting one’s head, one’s eye and one’s heart on the same axis.”
The sun rising during the spring and summer months in our sky means that heat and light reach our surface at a steeper angle. The result: noon on a summer day (the sun’s highest position) casts almost no shadows. Similarly, in the winter, the angle of the sun drops lower casting less concentrated heat and longer shadows. Just as the sun’s proximity to earth directly affects the Earth’s surface temperature, the angle of the sun also dictates the length of shadows. Areas closer to the equator experience much less of this phenomena because their relationship to the sun’s position is much more consistent year round.
Starting Monday, March 21 – the first day of Spring – we will start a three month daily “meditation” on the intersection of shadows, space and time. Will you join us? All you need is a willingness to commit to visiting a site in your neighborhood landscape every day at the same time, and an interest in tracking a shadow in your neighborhood to mark the climb of the sun. We welcome you to share your observations!
Here’s how: Choose an open area with plenty of direct sunlight, then pick an object that casts a distinct shadow. At the same time each day between the March 21 Spring Equinox and the June 21 Summer Solstice visit the object and measure the length of its shadow. Over time you should see the shadow shrink slowly. After the first month, make an estimate of how long you think the shadow will be at the end of your observations. And consider this: the days get longer, our shadows get shorter, but the sun doesn’t change size or temperature during the seasons, it is only our position that changes.
