FOG (fat, oil, grease) a constant threat to MUB's sanitary sewer system
They tend to gum up the works.
As part of the utility board's NPDES, or National Pollutant Discharge Elimination System, permitting process, MUB is taking a look at what General Manager Mike McNulty has identified as 'the number one issue' when it comes to backups in the sewer collection system.
Collectively known as FOGs, McNulty said MUB is seeing an increase in the amount of fat, oil and grease being dumped directly into its system.
While it's advised nobody knowingly pour grease or oil down the drain, the scale of the issue faced by MUB indicates it's originating at restaurants, which are required to have functional grease traps that are regularly checked and emptied.
According to McNulty, MUB has started working with the Monongalia County Health Department. Through its environmental health program, MCHD conducts regular inspections of food service facilities within the county.
'We're just trying to start the process to make our customers that do have grease traps more aware of what their responsibilities are in keeping everything in good working order so those fats and oils don't overflow into the sewer collection system,' McNulty said. 'MUB staff will be visiting the different restaurants. I think we've identified about 241 locations with restaurants and cafeterias, and I think MUB and the health department will make those inspections, in some instances, together.'
It was explained that restaurants typically contract with an outside service that pumps out the grease trap periodically. McNulty said checking manifests to verify regular servicing is part of the inspection process.
McNulty indicated MUB already has a good idea where some of the issues are starting.
'Yes, we do have some of that data,' he said. 'We do some regular, routine flushing on some lines … and we do know where some of the problems originate from.'
Dubbed 'fatbergs,' subterranean blockages made up of FOGs and other known culprits, like 'flushable' wipes, cause untold millions in property, infrastructure and environmental damage around the globe every year
It's estimated that 50% of sewer blockages in the U.S. are FOG-related.
On Monday, MUB dispatched a work crew with a vacuum truck to the Deckers Creek Rail Trail to clear a manhole that had become obstructed by grease.
A small, local instance of what can become a very large problem.
In one notable example from 2017, congealed grease restricted a midtown sewer main in Baltimore, pushing more than 1.2 million gallons of sewage into the Jones Falls River.
The following year, workers in Macomb County, Michigan discovered an 11-foot wide, six-foot tall blockage that stretched for more than 100 feet.
Small potatoes compared to the estimated 130-ton mass that plugged London's sewer system around that same time, requiring weeks of around-the-clock attention from specially-outfitted crews. A section of the 820-foot-long 'Whitechapel Fatberg' is on display at the London Museum.

FOG (fat, oil, grease) a constant threat to MUB's sanitary sewer system
MORGANTOWN — Much like a cardiologist, the Morgantown Utility Board is concerned with the intake of fat, oil and grease – and for similar reasons. They tend to gum up the works. As part of the utility board's NPDES, or National Pollutant Discharge Elimination System, permitting process, MUB is taking a look at what General Manager Mike McNulty has identified as 'the number one issue' when it comes to backups in the sewer collection system.

Group claims wastewater permit would let Manchester dump PFAS into Merrimack River
The Conservation Law Foundation (CLF) is arguing that the state's approval of a permit allows the Manchester Wastewater Treatment Facility to discharge toxic chemicals into the Merrimack River. An appeal filed Thursday with the New Hampshire Water Council claims the New Hampshire Department of Environmental Services approved the Manchester facility's National Pollutant Discharge Elimination System permit renewal on May 13 without evaluating or determining whether 'in light of discharges and emissions of per- and polyfluoroalkyl substances (PFAS) from the Manchester WWTF' the treatment facility's permitted activities will comply with New Hampshire's water quality standard for toxic substances and the Merrimack River's designated use for fish consumption. Merrimack River The Merrimack River in Manchester 'People deserve safe, clean water, and state regulators have a critical role to ensure that's what we have in New Hampshire,' Tom Irwin, the Conservation Law Foundation (CLF)'s vice president for New Hampshire, said in statement. 'By failing to consider whether PFAS chemicals are violating important safeguards intended to protect water and people from toxic pollutants, regulators are putting our environment and health at risk.' A request for comment from Manchester officials was not immediately returned Thursday. PFAS chemicals, known as "forever chemicals" because they do not break down in the environment or in human bodies, have been linked to several health problems like cancer; fertility issues; child-development disorders; hormonal dysfunction; and damage to the thyroid, kidney and liver. CLF says the chemicals are found in wastewater from industrial users sent to Manchester's treatment facility, the largest such plant in northern New England and the only one in New Hampshire that incinerates its sewage sludge. CLF's appeal argues the state agency failed to evaluate whether releases of PFAS chemicals from the facility — both in wastewater discharged into the Merrimack River, and emitted into the air from the facility's sludge-burning incinerator — violate water quality standards, including regulations aimed at protecting people who consume fish. In its appeal, CLF claims that the WWTF discharges 'treated' wastewater into the Merrimack River but the WWTF's treatment process does not address or remove PFAS. Manchester wastewater treatment plant stack The air emissions pipe from the Manchester wastewater treatment plant, as seen from Gay Street. 'The WWTF has detected PFAS in its influent and 'treated' effluent (wastewater) on a monthly basis since at least 2019,' the appeal says. 'In addition to discharging PFAS into the Merrimack River through wastewater discharges, the WWTF releases PFAS into the air through sludge incineration, as confirmed by data published in a peer-reviewed study in 2023 (the Seay Study).' The Manchester facility receives wastewater from at least 88 industrial users, 14 of which (including the city's closed landfill) are classified as Significant Industrial Users under EPA and local rules, the appeal says. 'The City of Manchester applied for a new (National Pollutant Discharge Elimination System) permit in 2019 and, in that application, did not disclose that its discharges contain PFAS,' the appeal says. When waste departs industrial sites in Manchester or surrounding communities like Bedford and Londonderry, it eventually winds up in the city's wastewater treatment facility, where a strainer removes debris. Solids settle at the bottom of a chamber until burned or put in a landfill, and bacteria eat any organic matter in the mix. The water is chlorinated, de-chlorinated, and put back into the Merrimack River. Leachate, a liquid found at landfill sites, is also handled at the Manchester facility. During the permit renewal process, CLF lawyers sent comments to the Department of Environmental Services in June 2024 that sources of PFAS — like wastewater treatment plants, landfills and manufacturing facilities — often disproportionately impact communities of color due to inequitable siting. 'Two U.S. Census Tracts that are located roughly two miles away from the WWTF and its incinerator are overburdened by environmental pollution,' the CLF wrote. 'One of these communities has a population that is 56 percent people of color, 62 percent low income ... another has a population that is 41 percent people of color, 43 percent low income. These two communities are located north and northeast of the facility, exposing them to health risks from breathing contaminated air when wind blows from the south. 'Manchester residents that fish near or downstream of the WWTF are also likely disproportionately impacted by the WWTF's PFAS pollution in water and air.' CLF lawyers claim PFAS pollution from the WWTF also threatens the health of residents in downstream communities that source their drinking water from the Merrimack River.

Funding uncertainty has MCHD in 'difficult financial straits'
Jun. 2—MORGANTOWN — In the best of times, annual budgets are uncertain. They're well-educated guesses — estimates, if you prefer the term. You look at what you expect to get, weigh that against what you expect to spend — and hope nothing happens along the way that negatively skews either number beyond reconciliation. But what if you have no real way of knowing what to expect ? That's where leadership with the Monongalia County Health Department often is finding itself. MCHD Executive Director Anthony DeFelice has estimated that up to 40 % of the health department's budget originates from federal sources. As with most sectors dependent on federal dollars, there's considerable uncertainty in public health. The MCHD launched into an unprecedented budgeting process knowing some of those dollars are secure, some have already been eliminated and some are complete unknowns. "The IAP Grant is the immunization grant. It's just been a given every year that you're getting that. We've had no indication. They stopped the IAP grant and terminated it, " county Health Officer Dr. Brian Huggins said. "We don't know if the Vaccines for Children (Program) is going to exist next year. Those are significant funding sources that help pay for some of our nursing staff. With this budget, we didn't include them. If we get them, great. But we just don't know." And that, DeFelice explained, is how MCHD is approaching this budgeting process. If leadership is confident the funds are secure, they're included. If there's any uncertainty, the dollars aren't being budgeted. DeFelice described the process as "very thorough " and "very conservative." Chief Financial Officer Devan Smith explained that the health department's program managers and executive team have gone meticulously through each line item in an effort to determine where reductions can be made. Smith said budgeting in public health is already both art and science in that it often requires as much intuition as accounting. "When you add in deep uncertainty about whether core functions of the organization will continue to be funded, it not only makes providing estimates difficult, but also means that you have to question what services will be kept or lost under different scenarios, " he said. "What made this budget year so hard for us was not the mechanical process of performing calculations or reviewing expenses. It was weighing the people element — -potential reductions in the services we are able to provide to families in our community or impacts to employees we have worked with for years that may no longer have a job." Among the measures under consideration are fee increases. An initial example is a 10 % bump in fees for the health department's dental program. A review of if, where and when MCHD can continue to offer free and reduced-cost services is under consideration. The health department also plans to keep all vacant positions unfilled. Further, some programming considered "enhanced " offerings — meaning beyond the core functions of environmental health, communicable disease, immunization, threat preparedness and community health promotion — are being scaled back as only core, or basic, functions are eligible for state and county support. Huggins offered an example. "The biggest thing that is changing is that our family planning clinic is going to go from five days a week down to a single day a week. The biggest reason for that is loss of funding streams that were supporting our basic services. Family planning is an enhanced service by state code. Family planning, unfortunately, loses money. It just does, " he said, explaining the program lost somewhere around $150, 000 in the 2025 fiscal year. "There is potential with family planning that we may have to discontinue services completely if the funding stream stops. According to the DHHS budget that's been proposed by the administration, family planning is on the list of services that is to be eliminated — not moved to a different service, eliminated from funding. If that occurs, we'll look at everything we can because we realize, for a lot of people, this is a critical service."
