Real-Time E. coli estimates for the French Broad River at Pearson Bridge available on new website from MountainTrue and NC DEQ

MountainTrue has partnered with the North Carolina Department of Environmental Quality (DEQ) and the Pigeon River Fund to create a new website that provides the public with real-time water quality estimates at Pearson Bridge on the French Broad River in Asheville, NC. The website combines existing technology and new mathematical modeling to estimate E. coli conditions in real time.

The modeling correlates water turbidity data provided by the U.S. Geological Survey with MountainTrue’s and DEQ’s E. coli data at Pearson Bridge. The French Broad River at Pearson Bridge is now one of the few places in the country to have a real-time E. coli estimate modeling system.

“The goals of the WNC Recreational Monitoring program are to empower and enhance the existing community of environmental organizations already monitoring water quality in WNC, while expanding the Department of Environmental Quality’s analytical abilities to shorten the turnaround time in E. coli analyses and further refine risks associated with elevated bacteria levels,” said Landon Davidson, Division of Water Resources Regional Manager. “Near real-time calculations of bacteria levels are valuable to users because rapid changes in river conditions can increase bacteria levels significantly.” For more information on the State’s WNC Recreational Water Quality program, visit the DEQ website.

French Broad Riverkeeper Hartwell Carson explains, “Summer is when river recreation is most popular, but it’s also when afternoon thunderstorms can roll in, cause significant runoff and drastically change water quality. This new technology helps eliminate that uncertainty by providing the public with real-time estimated bacteria levels so that they can make informed decisions about whether or how to spend time on the river.”

The French Broad River Watershed is one of the most popular water-based recreation areas in North Carolina. On any given warm day, the French Broad Watershed hosts thousands of tubers, swimmers, canoers, kayakers, anglers, and whitewater boaters. Recreators frequently wonder how clean the river is and if it’s safe to swim or paddle.

As part of its existing Swim Guide program, MountainTrue publishes E. coli data each week from May to September on the Swim Guide platform. MountainTrue utilizes the Environmental Protection Agency (EPA)-approved IDEXX method for collecting and analyzing water samples and compares the results against the safe standard for health determined by the EPA.

MountainTrue samples for E. coli because it’s the best indicator for the presence of microbes that pose threats to human health, such as Cryptosporidium, Giardia, Shigella, and norovirus. Heavy rains and storms often result in spikes in E. coli contamination, increasing the risk to human health. Contact with or consumption of contaminated water can cause gastrointestinal illness, skin, ear, respiratory, eye, neurologic, and wound infections. The most commonly reported symptoms are stomach cramps, diarrhea, nausea, vomiting, and low-grade fever.

While the Swim Guide program provides high-quality data, it suffers from a time lag, as E. coli samples take 18-24 hours to incubate. Water quality can vary significantly from week to week or even day to day. E. coli levels can change quickly with heavy rains, as stormwater triggers runoff from agriculture, sewer overflows, and failed septic systems. Swim Guide data taken from MountainTrue’s Pearson Bridge sampling site over the past month illustrates this problem. During a relatively dry period in June, E. coli levels at Pearson Bridge were well below the safe standard set by the U.S. Environmental Protection Agency (EPA). July’s heavy thunderstorms have caused E. coli levels at Pearson Bridge to spike significantly, including being over 25 times the EPA’s safe standard on July 13.

As our mountain region experiences increased high-intensity rain events as a symptom of climate change, developing a model that provides E. coli estimates to the public is important. The French Broad Riverkeeper says MountainTrue and DEQ want folks to have the resources they need to make more informed decisions about when and how to recreate the French Broad River. Now, this will be possible thanks to the real-time E. coli estimator model and the USGS Pearson Bridge turbidity gage data on which it is based.

These real-time estimates will also help the French Broad Riverkeeper and DEQ track sources of pollution as they continue working together to bring about a cleaner French Broad River.

Take Action Against Single-Use Plastic Pollution in Asheville and Buncombe County

Plastic pollution: we’ve all seen it littered on the side of the road, blowing in the wind, floating down rivers and streams.

Plastic pollution is a global problem, but we all have to be part of the solution. Together, we can stop plastic pollution at its source. Let’s enact common-sense laws at the state and local levels to limit the use of single-use plastics before they end up as litter in our rivers, lakes, and streams.

Take action against single-use plastic pollution in Buncombe County

Our water quality testing concludes that microplastic pollution is widespread throughout the French Broad River Basin and other Western North Carolina waterways. Together, we can stop plastic pollution at its source. That’s why we’re working with nonprofit partners to implement a single-use plastic ban in Buncombe County. We can and should enact common-sense legislation at the local level to limit the use of single-use plastics before they end up as litter and microplastic pollution in Buncombe County’s rivers, lakes, and streams. Visit the Plastic-Free WNC website to learn more about our plastics-focused work in Western North Carolina and Buncombe County.

MountainTrue Watershed Outreach Coordinator Anna Alsobrook clearly remembers the day she and French Broad Riverkeeper Hartwell Carson were confronted with the dismal reality of the plastic pollution crisis: “It was the final straw — figuratively and literally. A few years ago, Hartwell and I were paddling the Swannanoa River. Plastic was everywhere — thousands of plastic shopping bags littered the trees around us, and plastic bottles floated in the river like rafts of ducks. These weren’t new sights for us by any means, but they were the ultimate kick in the gut to start making more permanent changes to protect our rivers and streams.”

Watauga Riverkeeper Andy Hill on plastic pollution: “We’ve spent years conducting river cleanups, engaging hundreds of volunteers and partner organizations. We spend a lot of time on the Watauga, New, and Elk Rivers collecting water samples, planting trees, and tracking pollution. I thought we had a good handle on the plastic problem. A watershed change and paradigm shift for how I considered the issue came about when we partnered with the Town of Boone and Asheville Greenworks to install a passive litter collection device known as a Trash Trout. The data we began collecting on the type and amount of single-use plastics — including styrofoam and other littered items — truly blew us away.”

Microplastic pollution is widespread throughout the waters of Western North Carolina

Testing by MountainTrue shows that microplastics are present throughout the Broad, French Broad, Green, Hiwassee, Little Tennessee, New River and Watauga River Basins.

Western North Carolina — Regional conservation organization MountainTrue has documented the high levels of microplastics in surface water samples collected from waterways throughout western North Carolina. Microplastics are pieces of plastic smaller than 5 millimeters that are the result of the breakdown of larger plastic litter and debris into smaller and smaller pieces. They are harmful to aquatic life and are considered a potential threat to human health.

MountainTrue collected and analyzed water samples from the Broad, French Broad, Green, Hiwassee, Little Tennessee, New River and Watauga River Basins. We found microplastics in every sample from every region, even in otherwise pristine areas and protected watersheds. We documented an average of 19 particles of microplastic per liter of water across all tested watersheds. The highest particle counts of microplastics were found in the Little Tennessee (37 particles/liter) and Hiwassee (30 particles/liter) watersheds. Even in watersheds with lower levels of microplastic contamination, there were testing sites with concentrations in the high twenties and thirties.

Watershed	Avg no. of microfibers per liter	Avg no of microbeads per liter	Avg. no of microfragments per liters	Avg. no. of microfilms per liter	Avg no. of all microplastics per liter
Broad River	12	1	5	6	24
French Broad River	7	0	4	5	16
Green River	20	0	5	2	27
Hiwassee River	18	0	2	10	30
Little Tennessee River	29	1	3	5	37
New River	20	0	3	6	29
Watauga River	14	0	0	3	17
All Watersheds	12	0	2	5	19

Microfibers, which come from synthetic clothing and fishing line, was the most common form of microplastic that we observed. Microfilms, which degrade from plastic bags and food wrappers, accounted for more than a quarter of microplastics recorded.

There have been significant amounts of microplastics research in marine systems, but microplastics in freshwater systems have been less studied overall. MountainTrue’s study is one of the first to look at levels across western North Carolina in order to gain a general understanding of the amount of microplastics in our water. MountainTrue is partnering with the Waterkeeper Alliance on a state-wide study for all of North Carolina.

Microplastics can enter the environment as plastic litter degrades, in runoff from landfills, and through discharges from wastewater treatment plants. Once in the environment, they can travel for thousands of miles suspended in water or carried by the wind.

MountainTrue is partnering with businesses in Hendersonville to help them shift their operations away from single-use plastics toward reusable bags and compostable utensils and packaging through the Working to be Plastic Free partnership. In Buncombe County and the Town of Boone, MountainTrue is advocating for local ordinances that would encourage the use of reusable shopping bags by replacing single-use plastic bags with paper bags and charging a 10 cent fee that would be waived for shoppers enrolled in the SNAP or WIC programs. To learn how you can support these efforts visit plasticfreewnc.com.

“The first step to stop the contamination of our environment and our bodies is to reduce the amount of plastic that enters and escapes the waste stream,” explains Anna Alsobrook, MountainTrue’s French Broad Watershed Outreach Coordinator. “And that starts by breaking our dependence on single-use plastics like plastic grocery bags and fast food utensils and packaging.”

Microplastics are inadvertently ingested by fish and other aquatic organisms causing microplastics to be transferred throughout the food web. Researchers have found that microplastic ingestion can negatively affect freshwater fish through physical complications of passing plastic through the gut or false satiation. Microplastics can also leach harmful chemicals like plasticizers and additives into the organs of fish. The chemicals have varying effects on fish changing feeding rates, development and survival. Much of the research is focused on centrarchids. Centrarchids are the family of sunfish, and they are a sentinel species, so they are often used to detect risks to humans by providing advance warning of danger.

People consume microplastics in contaminated food and water, and by breathing them in. Microplastics have been found in seafood, salt, tap water and even in bottled water. It is estimated that, globally, people ingest an average of five grams, or the equivalent of a credit card, worth of plastic every week.

The effects of plastic pollution on human health is the subject of a growing body of research. A study has found microplastics small enough to be carried in the bloodstream in the placentas of pregnant mothers. Other research has shown that microplastics cause damage to human cells, including cell death and allergic reactions, at levels known to be consumed in food.

Other research has shown that it’s not just the plastics, but also the additives used to make them can have a harmful effect on human health. Phthalates, which are a family of chemicals used in food packaging, are known endocrine disruptors that harm the reproductive and nervous systems and have been linked to higher rates of childhood asthma and other respiratory conditions. Styrene, which is used to make styrofoam cups, food containers, and disposable coolers, leaches into the food and drinks they hold and from landfills into drinking water. The World Health Organization has classified styrene as a probable human carcinogen.

“These plastics can persist in our environment for hundreds if not thousands of years,” says Anna Alsobrook. “The more we learn about what plastics and the chemicals used to make them are doing to our environment and to our bodies, the clearer it becomes that we need to take action now.”

MountainTrue FAQ: SMIE Volunteering

Let’s chat bugs! Last December on the MountainTrue blog, we considered What’s Bugging Our Rivers. Today, we’ll take a deeper dive into our participation in the Stream Monitoring Information Exchange (SMIE) program and our partnership with the Environmental Quality Institute (EQI), based in Black Mountain, NC. We’ll split this blog post into two main sections: we’ll start with a summary of the SMIE program and our partnership with EQI and conclude with a brief SMIE volunteer FAQ.

About SMIE

SMIE is a collaborative, volunteer-based biological water quality monitoring program that analyzes aquatic macroinvertebrate population data from across Western North Carolina (WNC). The SMIE program was developed in 2004 by Clean Water for North Carolina (CWFNC) (as creative lead), EQI, Haywood Waterways Association, Riverlink, and two of MountainTrue’s predecessor organizations: the Environmental Conservation Organization (ECO) and the WNC Alliance.

Benthic macroinvertebrates — including aquatic stream bottom-dwelling insects like stoneflies, caddisflies, hellgrammites, and more — are excellent indicators of the comprehensive water quality of a stream because they have limited mobility, specific habitat requirements, and distinct pollution tolerance levels. You could say that aquatic macroinvertebrates are artists — they paint a revealing picture of the overall health of aquatic ecosystems. As the metaphorical art historians of the SMIE world, experts at EQI and their partner organizations analyze the physical cues left by these tiny yet essential aquatic insect artists. The expert analyses of SMIE data across multiple watersheds help us better understand our region’s vibrant water quality history and present reality.

About EQI and MountainTrue’s partnership

Our partnership began in 1992 when EQI partnered with ECO — one of MountainTrue’s three predecessor organizations — to conduct surface water monitoring in Henderson County as part of EQI’s *Volunteer Water Information Network (VWIN) program. Thirty years (and a whole lot of water quality testing) later, MountainTrue continues to collect and deliver monthly water quality samples to EQI, and we now provide EQI with our SMIE data for analysis.

One of EQI’s primary goals is to increase public awareness about regional water quality and environmental issues across WNC. Involving the public in the SMIE data collection process allows EQI and MountainTrue to significantly expand our sampling capacity and add credibility to citizen science programs.

EQI currently coordinates SMIE sampling at 49 sites in five WNC counties (Buncombe, Madison, Haywood, Mitchell, and Yancy). EQI also provides technical support for its partner organizations using the SMIE protocol throughout WNC and Eastern TN. As an EQI partner, MountainTrue coordinates SMIE volunteer training and sampling in Henderson, Polk, and Cleveland counties. SMIE sampling efforts occur each spring and fall, typically in April and October.

*One of EQI’s major programs, VWIN is a volunteer-based network that has been conducting chemical surface water monitoring in WNC streams on a monthly basis since 1990. Learn more about and get involved with EQI’s VWIN work here.

Why our partnership matters

The North Carolina Division of Water Resources (NC DWR) monitors water quality throughout the state, prioritizing testing sites with existing and pressing issues. The agency’s minimal number of testing sites and low sampling frequency have both continued to decrease over time due to lack of capacity — this means that water quality in many WNC streams is not regularly monitored… That’s where we come in!

The SMIE program monitors the water quality of urban, rural, and forested streams in priority WNC watersheds and tributaries without existing watershed plans or projects. By consistently monitoring WNC streams, EQI and MountainTrue can assess long-term water quality trends that highlight the interrelated relationship between the health of local waterways and resident aquatic insect populations.

This comprehensive knowledge provides valuable insights into the effects of *pollution in our local waterways. Essentially, WNC streams with higher pollution levels have fewer aquatic insects and are less hospitable to other aquatic and riparian species, like native fish, salamanders, and streamside plants. Alternatively, the presence of pollution-sensitive aquatic insect species indicates cleaner, healthier streams with greater biodiversity.

*The most common types of pollution include:

Stormwater runoff from impervious surfaces like parking lots, roads, buildings, and other structures. Littered trash is frequently swept up in the flow of running stormwater, quickly making its way into local waterways.
Bacteria and chemical pollution, often caused by sewer and septic system overflows, agriculture runoff, and industrial effluent.
Sediment pollution, often caused by erosion of stream banks, some animal agriculture practices, and runoff from construction sites and plowed fields.
Wastewater human and animal waste, industrial effluent, and trash.

SMIE Volunteer FAQ

Q: Why should folks want to volunteer for SMIE?

It’s a super fun way to connect with the environment and your community through citizen science and shared experience. SMIE volunteers get hands-on experience with a unique and essential facet of environmentalism (aquatic insects!) and make meaningful contributions to environmental protection!

Q: What does a typical SMIE volunteer day look like?

MountainTrue or EQI’s SMIE experts meet volunteers at our sampling sites and provide all the supplies needed for a day of aquatic insect sampling: nets, buckets, filters, ice cube trays, forceps, datasheets, and waterproof waders. A group leader accompanies each volunteer group, completing all aquatic insect identification and ensuring proper SMIE protocol is followed. The data collected by SMIE volunteers is recorded and sent back to the EQI or MountainTrue labs, where it’s entered into our long-term database.

In total, sampling an SMIE site takes between one and a half to three hours. Volunteers are expected to sample at least two SMIE sites each spring and fall season. We collect our samples using the three collection methods detailed in the SMIE protocol:

Kick Net Collection

One volunteer holds the large net while another kicks just upstream. The kicking disturbs the stream bed, dislodging aquatic insects from the sediment and off of rocks before they’re picked up in the stream’s flow and caught in the net. SMIE protocol calls for two volunteers to collect macroinvertebrates from the net for 20 minutes.

Leaf Pack Collection

Fallen leaves are an important source of nutrients and shelter for many aquatic insects. As the leaves move downstream, they collect on rocks, fallen sticks and logs, and along stream banks — as they decompose, insects move in. Volunteers fill a bucket with decomposing leaves and sort through the leaf pack to find insects. Volunteers can also collect insects with a strainer used to filter water from the soggy leaves. Volunteers typically spend five minutes collecting insects from the leaf pack.

Visual Collection

A volunteer wades through the stream and examines various microhabitats for aquatic insects. Insects are typically found under rocks, along river banks where tree roots interact with the stream, and in leaf packs. They can also be found by filtering stream water through a strainer.

Q: Do I have to be trained to volunteer? Where can I sign up for a training/when is the next one?

In order to ensure our data is reliable, the SMIE program requires all volunteers to be trained. EQI and MountainTrue host SMIE training workshops twice per year in the fall and spring. Training workshops are broken into morning and afternoon sessions. Morning sessions are education-focused — volunteers learn about the basics of stream ecology, aquatic insect identification, SMIE protocol, and the history and importance of the SMIE program and water quality monitoring in general. Afternoon streamside sessions offer volunteers the chance to put their newfound knowledge to the test — volunteers are trained in all collection methods and get hands-on practice with aquatic insect identification.

Additionally, EQI offers group leader training to especially passionate SMIE volunteers. Group leaders receive additional training in SMIE protocol and insect identification.

Both EQI and MountainTrue are hosting SMIE training workshops this spring! MountainTrue will be training volunteers for Henderson and Polk counties on March 5. EQI will be training volunteers for Buncombe, Madison, Haywood, Mitchell, and Yancy counties on April 2. Stay tuned for updates on upcoming training workshops in MountainTrue’s High Country Region!

Plastic-Free WNC

Plastic pollution: we’ve all seen it littered on the side of the road, blowing in the wind, floating down rivers and streams. Plastic pollution is a global problem, but we all have to be part of the solution.

Watauga Riverkeeper Andy Hill on plastic pollution: “We’ve spent years conducting river cleanups, engaging hundreds of volunteers and partner organizations. We spend a lot of time on the Watauga, New, and Elk Rivers collecting water samples, planting trees, and tracking pollution. I thought we had a good handle on the plastic problem. A watershed change and paradigm shift for how I considered the issue came about when we partnered with the Town of Boone and Asheville Greenworks to install a passive litter collection device known as a Trash Trout. The data we began collecting on the type and amount of single-use plastics — including styrofoam and other littered items — truly blew us away.”

MountainTrue Watershed Outreach Coordinator Anna Alsobrook clearly remembers the day she and French Broad Riverkeeper Hartwell Carson were confronted with the dismal reality of the plastic pollution crisis: “It was the final straw — figuratively and literally. A few years ago, Hartwell and I were paddling the Swannanoa River. Plastic was everywhere — thousands of plastic shopping bags littered the trees around us, and plastic bottles floated in the river like rafts of ducks. These weren’t new sights for us by any means, but they were the ultimate kick in the gut to start making more permanent changes to protect our rivers and streams.”

Following their experience, Anna and Hartwell started researching the plastics industry. The more they learned, the more they disliked. The strategy of the plastics industry is akin to the tobacco industry — both forced themselves on unsuspecting populations, fully aware of their products’ adverse health and environmental impacts. Both marketed themselves as “cool” and continue to disproportionately burden our most vulnerable populations with hazardous health concerns.

Cigarette usage has been on the decline since the tobacco industry’s regulation. The plastics industry, to this point, has gotten a free pass. Wrapped up in the oil and gas industry, Big Plastic is cozy with the idea of buying politicians and bullying consumers into buying their products. With few sustainable, affordable, and accessible plastic alternatives, we — the general public — remain Big Plastic’s captive audience.

Some places have started implementing their own rules on plastic — eight states have implemented their own single-use plastic bans, along with 345 municipalities across the nation. We at MountainTrue want to follow their lead, hopefully inspiring others to do the same. We based our proposed ordinance on the various successes of existing single-use plastic bans. It’s intended to mitigate plastic pollution in Western North Carolina by addressing the single-use plastic problem at its source.

Now, let’s get into the details:

We begin the ordinance with a whole slew of “Whereases” — a standard practice in bills and ordinances. Our Whereases spell out atrocities of the polluted reality perpetuated by the plastics industry: a reality characterized by environmental injustice, rife with increasingly negative impacts on human and environmental health.

The ordinance’s first section defines key terms and concepts, like what makes an item single-use, compostable, reusable, etc. We based these definitions on best practices across the country.

The following sections are the figurative meat of the ordinance:

Section two details prohibitions on:

Polystyrene as a primary chemical additive in styrofoam food and beverage containers
Plastic shopping bags at points of sale
Plastic stirrer sticks and splash guards
Plastic straws (we recommend a request-only policy, though nursing homes and hospitals are exempt from this policy)

Some items in this section have built-in exceptions: the ban on plastic shopping bags excludes bags used for produce, bulk items, meats, seafood, flowers, small hardware, live animals (like fish or insects), dry cleaning, or hotel-provided laundry bags. It also excludes yard waste, pet waste, and garbage bags.

With the ban on plastic shopping bags at points of sale, we hope to encourage people to bring their own bags to the store. But, people are human and will forget sometimes. To cover those times, stores can provide paper bags for a fee of $0.10 each. They can also offer reusable bags for sale at checkout. Some locations already provide empty cardboard boxes for customers to use, and that’s ok too. The purpose of the paper bag fee is to discourage customers from relying on paper bags — which have their own environmental impacts — each time they shop. Anyone with SNAP or WIC benefits will be exempt from the fee.

Section four highlights our proposed bans on disposable plastic service ware. The ban differentiates dine-in versus take-out operations. We recommend that no disposable plastic service ware be provided for dine-in customers and encourage businesses to provide reusable service ware instead. Should a business lack the dishwashing capacity to provide reusables, they are exempt and can provide alternative sustainable service ware. We recommend businesses provide no disposable plastic service ware for take-out operations and instead provide sustainable service ware at the customer’s request.

The next sections highlight the ordinance’s implementation and enforcement criteria:

From the passage of the ordinance, businesses will have a set amount of time to source new sustainable alternatives and exhaust their current stocks of and contracts for single-use plastics. Businesses that fail to comply with the ordinance after that period will face penalties of $100 for a first offense, $200 for a second offense, and $500 for a third offense.

You can read our proposed ordinance in its entirety here.

Together, we can stop plastic pollution at its source. Let’s enact common-sense laws at the state and local levels to limit the use of single-use plastics before they end up as litter in our rivers, lakes, and streams. Visit our Plastic-Free WNC site to learn more and take action against plastic pollution in WNC. And join us at 7 p.m. on January 26 for our virtual screening of The Story of Plastic.
