Tell FERC to Protect Mountain Rivers

On October 4, 2021, the Oconaluftee River below Ela Dam — once a high quality mountain river — was completely filled with sediment during a reservoir drawdown for a repair by the dam’s owner, Northbrook Carolina Hydro II, LLC.

Tell FERC to protect rivers in the Little Tennessee and Hiwassee River basins by monitoring and enforcing the provisions of Northbrook’s license for the Bryson, Franklin, and Mission Hydroelectric Projects.

MountainTrue has been tracking the successful efforts of state agencies and the U.S. Army Corps of Engineers to hold Northbrook accountable for this disaster. However, our review of public documents revealed that Northbrook “has conducted no active sediment management activities since obtaining the Bryson Project” in 2019. Furthermore, the company hasn’t developed the long-term sediment management plans required by the Federal Energy Regulatory Commission’s project license at any of its three Nantahala Projects: Bryson on the Oconaluftee (where the massive sediment release occurred), Franklin on the Little Tennessee River, and Mission on the Hiwassee River.

Our mountain rivers contain a dazzling array of wildlife species, some of which are threatened or endangered. High quality water means high survivability for aquatic wildlife, especially those species most sensitive to pollution. Increased sediment pollution in our local waterways makes it difficult for native wildlife to feed, mate, move, and even breathe. This was the unfortunate fate suffered by many aquatic species when tons of sediment were unloaded into the Oconaluftee River last October.

Mountain rivers often provide our communities with drinking water. They’re also important recreational resources in our region, hosting a wide variety of recreation opportunities, including fishing, snorkeling, canoeing, and kayaking.

Hydroelectric dams owned by private companies like Northbrook are licensed every 30-40 years by the Federal Energy Regulatory Commission (FERC). Licenses have many pages of provisions designed to minimize impacts to human safety and the environment from the dams and their operations. But FERC’s responsibility doesn’t stop when the license is finalized. FERC must ensure that the requirements of the license are met to protect our river resources!

We’ll deliver this petition to FERC on January 28, 2022. We’ve got to do all we can to prevent a catastrophe like this from happening again!

Update: Thanks to all who signed on! We’re thrilled to have exceeded our goal of 500 signatures. MountainTrue will continue to monitor the situation — stay tuned for updates!

MountainTrue FAQ: Live Staking

We love live staking here at MountainTrue, as it’s one of the easiest and most effective ways to support native biodiversity and stream bank restoration! This blog hopes to answer many of the frequently asked questions we get about live staking. Most of this information is general, but some is specific to the Watauga Basin and Riverkeeper Program.

Q: What’s live staking?

Live staking is a method of stream bank repair using native tree cuttings to revegetate the riparian buffer. The riparian buffer consists of trees, shrubs, and grasses alongside stream banks — it plays a crucial role in protecting stream health. The resiliency of riparian buffers is frequently impacted by land use. Activities like mowing to the edge of a stream, cutting down trees to see the water, or new development can negatively impact water quality. By live staking, we can positively and directly impact the overall health of our waterways!

Q: Where do you get the stakes from?

We get our live stakes from Foggy Mountain Nursery in Lansing, NC — their team harvests the stakes from native tree species, cutting stakes two to three feet long and one-half to two inches thick. While it’s possible to cut the stakes ourselves, we choose to support a fantastic local business and ensure that we’re planting the correct species. We’ve also harvested stakes from our previous live staking sites, where planted stakes have become well established.

Q: How do you choose where you’ll be planting?

We prioritize local public parks and river accesses because they’re easy to access and directly benefit the public. We’ve frequented Valle Crucis Community Park in Banner Elk, Cove Creek, and other public riverside locations around Watauga County. We also partnered with the City of Hendersonville to host two live staking workdays in Henderson County this February!

Q: What species do you plant?

We only plant tree species native to our region — primarily silky willow, silky dogwood, elderberry, and ninebark stakes. We’ve also planted other species, like buttonbush, black willow, and red stem dogwood. Recommended for stream bank repair by the NC State Cooperative Extension, these native tree species prefer moist soil and thrive in riparian habitats. These species support native wildlife, especially local pollinators. They can also establish extensive root systems to successfully hold soil in place along riparian buffers, ultimately preventing erosion.

Q: Why do you plant during the winter?

Live stakes are living cuttings of dormant trees that can propagate or sprout a new plant from the cutting of the parent plant. During winter, trees enter a state of dormancy to conserve their energy and weather the colder temperatures. Our live staking season lasts from November to March. We plant hearty hardwood stakes that use their energy to establish roots, waiting until spring to grow their branches and leaves. These resilient roots serve as a stream bank’s first line of defense against erosion, especially during high-flow events. Planting live stakes while tree species are in their natural pattern of energy conservation allows for a higher likelihood of survival along riparian buffers.

Q: How successful are the stakes?

Live stakes have a survival rate of 30-80%. However, survival varies from species to species and depends on environmental conditions. For example, we’d likely have very low survivability if a drought occurred after planting. But, if we plant under ideal conditions using correct planting techniques and have favorable weather post-planting, our stakes can do remarkably well! We can also remove invasive plant species and water the freshly planted live stakes to give them a better chance of success.

Stakes are most successful when planted along naturally sloped stream banks. They can still be planted on extremely incised banks, though they’re more likely to be less impactful in those locations. In our experience, silky willow and silky dogwood stakes tend to fare better than other native tree species we plant.

Q: How long does it take for the stakes to grow?

Roots, leaves, and branches can be well established after one growing season. From there, they continue to grow in length from the tips of their roots and branches year after year.

Q: How do live stakes benefit our waterways?

Live stakes grow root systems that hold soil in place and prevent erosion in local waterways. Sediment pollution remains a significant threat to the Watauga River Basin. This type of pollution clogs aquatic habitats and transports toxic substances through local waterways, increasing water temperatures and negatively impacting native biodiversity.

Once planted, small live stakes will grow into larger trees that stabilize and support riparian buffer health. Healthy riparian buffers benefit stream health in a multitude of ways — they also absorb nutrients, create wildlife habitat, and reduce the intensity of flooding from rain events. Unvegetated streams are often incised and can lose several feet of bank in a single rain event — this can be detrimental to nearby homes and other structures.

Q: What’s a typical day of planting?

We prep the stakes by cutting the live ends at a 45-degree angle. The NC State Cooperative Extension states that such cutting is enough to catalyze root growth at the nodes. The folks at Foggy Mountain Nursery kindly mark the planting ends of our stakes, so we know which ends to cut (pictured right). Once prepped and ready, we take the stakes in buckets down to the stream. We plant along the bank from the water’s edge to the bank’s top — not in the actual stream bed. Stakes are planted at an angle and submerged into the soil about two-thirds of the way. From there, the rest of the work is up to the stakes!

Swim Guide Watershed Report: Watauga River Watershed

In the past year, the Watauga River Watershed experienced a range of highs and lows (we’re talking about bacteria counts, folks!). We’ll start with the good news, including which water testing sites had the lowest bacteria counts across the watershed. Then, we’ll give you the year’s bad news by spotlighting sites with the highest bacteria counts. We’ll conclude with achievable solutions for the future and a call to action so you can continue to help us protect the places we share.

Before we dive into our water quality summary, let’s review important terminology to help us better understand the data our Riverkeepers, volunteers, and Clean Waters teams worked so hard to collect, analyze, and report. Cfu, or colony forming unit, is a metric scientists use to estimate the number of microbes present per 100 milliliters of a singular water sample. Microbes (also known as microorganisms) include bacteria, algae, and fungi. Like most things, some microbes are good for human health and some aren’t. We test for E. coli bacteria because it’s the best indicator for the presence of microbes that pose threats to human health.

According to the US Environmental Protection Agency (EPA), 235 cfu/100mL is the safe standard for primary recreational waters, where people are most likely to engage in recreational activities involving underwater immersion and potential water ingestion.

Good news headline: Popular Watauga River Spots Still Safe for Recreation

Popular among anglers, swimmers, sunbathers, and kayakers, our water quality testing site at Guy Ford remains the only Watauga River site to have experienced a statistically significant decrease in E. coli levels from 2020-2021. With an average value of 80.3 cfu/100mL, Guy Ford passes the EPA’s 235 cfu/100mL safe standard with ease.

About Our Swim Guide Program

Swim Guide is an international program used by Riverkeepers and other advocates to provide up-to-date recreational E. coli data for beaches, lakes, and rivers worldwide. E. coli is a bacteria found in the fecal waste of warm-blooded animals, including humans, and indicates contamination in our waterways. E. coli levels increase with rainfall events due to surface runoff and sewer overflow events.

Samples are collected every Wednesday from Memorial Day to Labor Day. Volunteers collect surface water samples in a 100mL sample bottle and drop samples off at the lab, to be processed by MountainTrue staff. Results from samples are measured in MPN, the most probable number of colony-forming units (cfu). The EPA’s limit for recreational water quality is 235 cfu/100mL. The EPA estimates at that concentration, 8 in 1,000 people will contract an illness.

Pass/Fail results are updated every Friday on www.swimguide.org to inform the public about local water quality. We use the data generated from our Swim Guide Program to identify sites for follow-up sampling. We sample in both urban and rural areas. Determining the location and source of E. coli in our waterways is one way we can hold polluters accountable.

Our other best testing sites of 2021 include the Upper Gorge Watauga Park off Highway 321, Watauga Point, Wilbur Dam, Shook Branch, and Price Lake. All five sites passed the EPA’s safe standard.

Data collected from 76% of all 18 sampled sites reported no statistically significant change this year, meaning E. coli levels did not increase or decrease from 2020-2021. While this isn’t the result we’d hoped for, we’ll take it.

Bad news headline: E. Coli has a Dirty Affair with Lover’s Lane and Other Popular Spots in the Watauga River Watershed

Our data showcases the pressing need for water quality improvement across the Watauga River Watershed. Unfortunately, sites along the Watauga, New, and Elk Rivers rank among the Watauga River Watershed’s worst testing sites. This year, popular Watauga River accesses like Lover’s Lane, Hunter Bridge, and Blevins Road Boat Ramp experienced alarming increases in bacteria concentrations.

Our Lover’s Lane site secured the top worst spot with an average E. coli count of 1754.9 cfu/100mL. Average E. coli levels were approximately three times the EPA’s 235 cfu/100mL safe standard at Hunter Bridge and Blevins Road Boat Ramp.

With E. coli levels above 590 cfu/100mL, both Elk River Falls and the New River’s Todd Island Park failed to pass the EPA’s safe standard. The latter, along with the New River’s Boone Greenway, ranked among Watauga County’s worst sites of 2021. Our Watauga River testing site off Calloway Road also fared poorly.

This year we saw 17% of our water quality testing sites experience increased overall E. coli levels compared to 2021. This increase is not considered statistically significant due to the wide variation among this year’s water quality samples, taken weekly during the 15 weeks between Memorial Day and Labor Day.

Our weekly sampling often took place after or during a rain event. We believe that likely contributed to this year’s wide variation in average E. coli levels, which was double that of 2020’s.

This year’s increase in average E. coli levels is a concerning trend across the watershed. The average E. coli count for 2021’s 15-week sampling period was 408.04 cfu/100mL, up from 2020’s average of 238.76 cfu/100mL.

Hurricane Fred caused the week of August 18 to be the summer’s worst. After Fred’s heavy rainfall and flash flooding events, the watershed’s E. coli levels skyrocketed to 1222 cfu/100mL. Additional rain events correlated with the summer’s other average E. coli level peaks.

Future news headline: Direct Action Needed to Mitigate Impacts of Climate Change, Increased Development, and Tourism Across Watauga River Watershed

A symptom of climate change, increased annual rainfall and flash flooding events, will undoubtedly cause a decline in water quality across the watershed. Growing tourism pressure and resulting development projects will continue to exacerbate the existing strain on our region’s failing infrastructure.

If left unchecked, stormwater infrastructure deficiencies will open the literal and figurative flood gates, allowing increased polluted and bacteria-laden stormwater runoff to enter local waters.

Moving forward, MountainTrue will:

Encourage government officials to implement policies addressing land use and development impacts and make worthy investments to improve existing stormwater infrastructure.
Continue to monitor sites of most concern while aiming to pinpoint and eliminate sources of E. coli pollution at our newest testing sites in the near future.
Further develop valued relationships with community members to combat threats posed to water quality by poor development and agricultural practices.

Swim Guide Watershed Report: Hiwassee River Watershed

For the Hiwassee River Watershed, the 2021 water quality testing season gave rise to laudable successes. It also illuminated the need for deliberate action in areas of most concern. We’ll start with the good news, including which water testing sites had the lowest bacteria counts across the watershed. Then, we’ll give you the year’s bad news by spotlighting sites with the highest bacteria counts. We’ll conclude with achievable solutions for the future and a call to action so you can continue to help us protect the places we share.

Good news headline: Lakes Largely Free of E. Coli and Other Pathogens

Twenty twenty-one has been kind to Hiwassee Lake, Lake Chatuge, and Late Nottely. Sites on these three lakes produced a total of 11 readings with zero E. coli or other pathogens. Hiwassee Lake at Hanging Dog secured this year’s prize for best site with an average E. coli count of 6.5 cfu/100mL.

Determining the location and source of E. coli in our waterways is one way we can solve pollution problems.

Bacteria levels in Lake Chatuge’s swimming beaches at Jackrabbit Mountain and in Towns County, Georgia, were commendably low. With an average E. coli count of 25.4 cfu/100mL, Lake Nottely’s Poteete Creek Park swimming beach also passed the EPA’s 235 cfu/100mL safe primary recreation standard with flying colors. Additionally, Clay County’s Fires Creek proved to be in good condition.

While not as clean as Hiwassee Lake or Lake Chatuge, samples taken from Lake Nottely and along the Nottely River showcase the relatively clean quality of these western waters. We collected our water quality samples during the 15 weeks between Memorial Day and Labor Day. Fortunately, our testing site at Nottely Dam failed to pass the EPA’s safe primary recreation standard only once.

Bad news headline: Heavy Rains, Leaky Septic Systems, and Animal Agriculture are Culprits of Hiwassee River Watershed’s Bacteria Pollution

Our Valley River site at Konehete Park rushed into 2021’s top worst spot with an E. coli count of 914 cfu/100mL, failing to pass the EPA’s safe primary recreation standard 80% of the time. Years of continued bacteria pollution have sadly caused the lower end of the Valley River to remain on North Carolina’s List of Impaired and Threatened Waters.

Poor animal agricultural practices, domesticated Canada Goose populations, and leaky septic systems are the primary causes of pollution in the Valley River. Monthly testing conducted upstream in both Andrews and Marble indicate that the Valley River’s E. coli problem is presently contained in the lower third of the river system.

Similarly, animal agriculture in the Sweetwater Creek Watershed is likely a primary contributor to the Hiwassee River’s larger E. coli pollution problem. One of our worst testing sites along the Hiwassee River, Sweetwater Park’s average E. coli count of 396 cfu/100mL failed to pass the EPA’s safe primary recreation standard 40% of the time. Monthly testing conducted upstream and downstream of Sweetwater Park suggests the bacteria pollution is currently isolated in a small portion of the Hiwassee River, including the confluence of Sweetwater Creek.

Another one of our worst sites of 2021, Meeks Park II canoe/kayak launch on the Nottely River produced an average E. coli count of 342 cfu/100mL and failed to pass the EPA’s safe primary recreation standard 53% of the time.

The week of September 1 proved to be the summer’s worst, with the aftermath of Hurricane Ida wreaking havoc across much of the Southeast. On average, the Hiwassee River Watershed received four inches of rain in the 48 hours before that week’s samples were taken. Ida’s increased rainfall caused the average E. coli count across each of our 10 water quality testing sites to spike at 371 cfu/100mL.

The weeks of August 11 and 18 also saw portions of the Hiwassee River Watershed receive several inches of rainfall shortly before our samples were taken. Hurricane Fred’s surge of stormwater in mid-August resulted in the highest overall E. coli levels of the summer at seven of our testing sites.

Future news headline: Mitigating Threats Posed to Hiwassee River Watershed by Pollution

The Hiwassee River Watershed is relatively clean. Still, we must be wary of negative changes associated with future summer seasons’ heavy rains. Polluted stormwater runoff remains a formidable threat to the Hiwassee River Watershed and the whole of the Southern Blue Ridge.

Water quality will suffer as higher annual amounts of stormwater runoff enter local waters due to climate change. Poor animal agriculture practices, outdated stormwater infrastructure, and decrepit septic systems will lead to future declines in water quality. That’s why we need to take action to address climate change — a pressing issue that affects us all.

MountainTrue is currently working with our state legislators to reinstate the Waste Discharge Elimination (WaDE) program, which is focused on identifying and fixing impaired septic systems. We also aim to secure increased funding for County Soil and Water Conservation Districts through our work with the North Carolina State Legislature. This necessary funding would help farmers adopt additional best management practices, like fencing livestock out of waterways and installing stream buffers to mitigate bacteria-laden runoff.

We believe these solutions will significantly improve the Valley River’s water quality and positively impact other Hiwassee River Watershed sections.

Moving forward, MountainTrue will:

Encourage government officials to implement policies addressing land use and development impacts and make worthy investments to improve existing stormwater and septic system infrastructure.
Continue to monitor sites of most concern while aiming to pinpoint and eliminate sources of E. coli pollution at our newest testing sites in the near future.
Further develop valued relationships with community members and our local Soil and Water Conservation Districts to minimize threats posed to water quality by poor animal agriculture practices.

Swim Guide Watershed Report: Upper French Broad, Green & Broad River Watersheds

While the past year has been unkind to the French Broad River, the Green River Watershed — a headwater tributary of the Broad River — had a great year. Alternatively, the larger Broad River Watershed’s 2020-2021 highlight reel is less glamorous, but we’re happy to report commendable water quality improvement across this important watershed.

We’ll split this blog post into three sections, starting with a summary of our upper French Broad River Watershed data. Then, we’ll discuss the data we collected across the Green River and greater Broad River Watershed, summarize the good and bad news for each, and spotlight the water testing sites with the lowest and highest bacteria counts. We’ll conclude with achievable solutions for the future and a call to action so you can continue to help us protect the places we share.

News headline: Upper French Broad Bedevilled by Bad Bacteria

The French Broad’s turbulent history with E. coli is well-known among watershed locals. Our two new testing sites along the upper French Broad at Lyons Mountain and Island Ford secured the top spots for worst water quality and highest bacteria count.

In Henderson County, Mud Creek at Brookside Camp Road experienced slight improvement from 2020 to 2021, but remains one of the worst sites we sample with an average E. coli count of 1535 cfu/100mL. Our data suggests a mix of animal agriculture, septic failures, and sewer overflows are the primary sources of E. coli pollution in Mud Creek.

The week of July 28 proved to be the summer’s worst. Just 23% of our French Broad River testing sites passed the EPA’s 235 cfu/100mL safe standard for primary recreational waters.

For more information about the larger French Broad River Watershed, check out this blog post.

Let’s move on to the Green River Watershed.

Good news headline: Green River Watershed Report Concludes ‘It’s Actually Pretty Easy Being Green’

We’re happy to report the past year saw the Green River Watershed boast no worst sites. With the exception of the week of August 18 during Hurricane Fred, all seven testing sites routinely passed the EPA’s safe standard throughout the summer.

Overall, the Green River’s water quality remains excellent for recreational users and fares much better than the French Broad River’s water quality. Out of 98 total samples, only nine failed to pass the EPA’s safe standard. Our data shows the Green River was clean 90.8% of the time we sampled it this summer.

Bad news headline: Rains of Climate Change Pose Threats to Overall Clean Green River

Users of the Green River Watershed enjoy a largely clean present. Still, the future is less certain with the potential for negative changes due to heavier summer rains. This summer saw Hurricane Fred wreak havoc across the watershed in mid-August, immediately resulting in poorer water quality. With an average value of 951.9 cfu/100mL per site, the week of August 18 proved to be the summer’s worst with six out of seven testing sites failing to pass the EPA’s safe standard.

Stormwater runoff pollution remains a formidable threat to the Green River Watershed and the whole of the Southern Blue Ridge. Without immediate and direct action, the Green River’s water quality will suffer as higher annual amounts of stormwater runoff enter the watershed due to climate change.

Now, let’s discuss the state of the Broad River Watershed.

Good news headline: Broad River Somewhat Less Bacteria-laden in 2021 than 2020

Sampled weekly from Memorial Day to Labor Day, our data concludes slight water quality improvement at all nine testing sites across the Broad River Watershed in both Rutherford and Cleveland counties from 2020-2021. We’re happy to say that the river continues to be a safe, reliable recreation spot.

Cleveland County’s Moss Lake maintains the title of best testing site, passing the EPA safe standard 100% of the time over the past two years.

Bad news headline: Development and Manure are Broad River’s Biggest Bacteria Blunders

Buffalo Creek has remained our worst testing site for two years, failing to pass the EPA’s safe standard 81% of the time. The high bacteria concentrations in Buffalo Creek are attenuated in Moss Lake, just 15 miles upstream. The nutrients associated with Buffalo Creek’s high bacteria levels continue to pose a risk for algal blooms in Moss Lake. Not all algal blooms are dangerous, but those with the potential to form in Moss Lake would pose a severe risk to water quality and surrounding biodiversity.

Lake Lure and the Rocky Broad have mixed testing results. Coupled with existing agriculture, ongoing development surrounding the Rocky Broad is likely causing an increase of bacteria-laden runoff during rain events.

Data from our two testing sites along the First Broad River indicate that the water is unsafe for recreation roughly 33% of the time. Poor agricultural practices like inadequate stream buffers and abundant cow and poultry manure in the river are the likely sources for the First Broad’s high E. coli levels.

Let’s wrap up our water quality discussion with two future news headlines:

1) Governments Must Step in to Mitigate Green River’s Worsened Water Quality

Existing stormwater infrastructure is outdated and inadequate. Local and state government action is needed to protect the Green River’s water quality from threats posed by climate change.

2) Remedying Broad River’s Bacteria Problem with Sound Policy, Infrastructure and Agriculture Investments

Despite incrementally improved water quality at each testing site, data collected from the Broad River Watershed still produced less than ideal results. The prevalence of E. coli in the watershed illuminates a dire need for workable solutions to lackluster development policies, poor agricultural practices, and deficient stormwater infrastructure.

Moving forward, MountainTrue will:

Encourage government officials to implement policies addressing land use and development impacts and make worthy investments to improve existing stormwater infrastructure.
Continue to monitor sites of most concern while aiming to pinpoint and eliminate sources of E. coli pollution at our newest testing sites in the near future.
Further develop valued relationships with community members to combat threats posed to water quality by poor animal agriculture practices.

Good news headline: French Broad Whitewater Sites Experience Applaudable Improvement in 2021

The French Broad in Madison County was cleaner this summer than in past Swim Guide seasons. Whitewater sections at Stackhouse, Hot Springs, and Big Laurel were some of the best testing sites. These sites routinely passed the EPA’s 235 cfu/100mL safe standard, improving from 2020-2021. Another popular whitewater section — the Pigeon River in Hartford, Tennessee — was clean all summer, with most weeks showing an E. coli count of zero.

Most of our testing sites experienced slight improvement this year compared to 2020’s testing results. This is likely due to less rainfall during the Memorial Day to Labor Day sampling season.

The French Broad’s long and sometimes stinky history with E. coli is no secret to watershed locals. Our riverkeepers, volunteers, and Clean Waters Teams kept keen (but not pink!) eyes out for harmful strains of this belligerent bacteria while conducting water quality tests at 40 sites across the French Broad River Watershed.

We added two new testing sites along the French Broad in Transylvania County at Lyons Mountain and Island Ford this year. Unfortunately, both sites’ water quality and bacteria count ranked among the worst. Our testing site in South Asheville’s Shiloh community secured the worst spot with a season average of 3393 cfu/100mL.

Hominy Creek in West Asheville remains an E. coli haven. Through separate DNA sampling, we’ve been able to identify cow and human waste as the top sources of E. coli in Hominy and Mud Creeks. At the same time, sewer overflows also negatively impact the latter. While Mud Creek at Brookside Camp Road experienced slight improvement from 2020 to 2021, it remains one of the worst sites we sample with an average E. coli count of 1535 cfu/100mL.

The week of July 28 proved to be the summer’s worst. Just 23% of the sites passed the EPA’s safe standard with 1283 cfu/100mL as the average value per site.

Future news headline: Staving off the French Broad’s Bacteria Pollution to Save Water Quality

While we saw a slight improvement this year, there’s much work that needs to be done to reduce bacterial pollution in the French Broad River. We’re advocating for additional funding for County Soil and Water Conservation Districts to help farmers implement additional best management practices, like keeping livestock out of waterways and installing stream buffers to mitigate harmful, bacteria-laden runoff. We believe these solutions will significantly improve water quality at Hominy Creek and other agricultural areas, engendering a free-flowing domino effect that will positively impact other French Broad River Watershed sections.

Moving forward, MountainTrue will:

Continue to monitor sites of most concern while aiming to pinpoint and eliminate sources of E. coli pollution at our newest testing sites.
Leverage our connections with city, county, and state officials while further developing valued relationships with community members to combat threats posed to water quality by animal agriculture, faulty wastewater infrastructure, and septic failures.
