University of Delaware study IDs 2,000 century-old lead pipes in Wilmington
From Philly and the Pa. suburbs to South Jersey and Delaware, what would you like WHYY News to cover? Let us know!
Hidden beneath Wilmington’s streets for nearly a century, lead pipes have quietly carried water through thousands of homes. But thanks to a recent effort led by University of Delaware researchers and students, the city now has a clearer picture of how widespread the old pipes are, and what needs to happen next.
A team of environmental engineering students, working under Gerald Kauffman, director of the University of Delaware Water Resources Center, conducted careful research into historic city records.
“Out of the 70,000 [connections], the bottom line is working with the city’s consultant, the city’s Department of Public Works and the students, they found that 2,000 of the pipes of the 70,000 are lead,” Kauffman said.
The findings mark a crucial step in identifying and replacing hazardous pipes that could pose health risks to residents.
The unfortunate legacy of lead, why these pipes still exist
The use of lead in water pipes dates back to the late 19th century, when it was a preferred material due to its durability and flexibility.
“Going back to the first water pipes that were actually installed in Wilmington in the late 19th century before the turn of the 20th, many of the pipes were lead. That was a material that was easily molded, and little was known about the health effects,” he said.
Congress banned the use of lead pipes in new construction in 1986. But older cities — particularly in the Northeast — still have remnants of these outdated systems. Last year, the Biden administration issued new rules through the EPA that would require old lead pipes to be replaced.
Most modern homes and renovations now use safer materials like copper, while older neighborhoods remain at risk.
Exposure to lead in drinking water has been linked to serious health issues in a child’s development, including neurological damage. Kauffman pointed out examples like the Flint Michigan’s water crisis that underscored the dangers of lead contamination, making identification and replacement of these pipes a high priority.
How UD students helped map Wilmington’s lead problem
The project began when Wilmington’s Department of Public Works approached the University of Delaware Resources Center for assistance. Using decades-old, handwritten public records, students worked to identify where lead pipes were most likely located.
“The idea was to go through the maps that the city has, and we have GIS maps in our office in Newark, and go through all the repair books, the plumbers, the inspectors that the city would send out to work with the homeowners to fix the pipes,” Kauffman said, describing it as a tedious process. “This is physically pouring through these old, handwritten plumbing repair records, and cursive writing and abbreviations … some of these go back to 1926.”
The findings were significant — not just in scale, but in their impact on cost-saving efforts. Instead of the city having to dig up lawns and streets to locate lead pipes manually, the students’ work provided a targeted list of affected homes.
“My estimate is that the students saved the city about $15 million,” he said.

Under plan, 59% electric rate hike to be phased in
Delmarva Power has proposed phasing in electricity rate increases to reduce the shock of a 59% price hike for residents scheduled to begin May 1.
If the proposal is approved by the state, the typical residential bill would go up slightly less than $18 a month on May 1. Then on Jan. 1, the typical bill would go up again by the same amount. On May 1, 2007, a last increase of $34 would be added, assuming no other change in the market price for electricity. …
Delmarva Power officials unveiled the proposal Tuesday as part of a response to an executive order issued last month by Gov. Ruth Ann Minner. She asked state agencies to study possible responses to the rate hike, including the option of reregulating the industry.
In 1999, state lawmakers removed controls on the price of wholesale electricity, reshaping the power market in the state. As part of the change, electricity rates were lowered by 7.5% until 2003.
Delmarva Power says the coming 59% increase is mainly caused by price hikes in the cost of the fuels that generate electricity, such as natural gas and coal.
Under deregulation, Delmarva must buy about one-third of its total power needs on the wholesale market every year. If the wholesale market is lower next year, customers could save some money. If the wholesale market is up, then rates could go even higher than they are currently expected to go….
Deregulation was expected to reduce electricity prices by bringing competition to the electric market, but only the largest power customers in the state are able to shop for power. Residents do not have a choice about who supplies their electricity.
Some lawmakers are calling for the state to reregulate the industry….
Reregulating part or all of the electricity market is unlikely to have any impact on the 59% rises in bills, experts say, but could prevent dramatic price spikes in the future….

Sussex prison dilemma prompts judicial warning
If the General Assembly doesn’t do something soon about the crumbling Sussex Correctional Institution, he will, a federal judge strongly hinted yesterday.
Judge Murray M. Schwartz said he frankly hopes lawmakers will come up with the extra $1.6 million needed for a thorough overhaul of the Georgetown prison this month.
If they do, he said, it probably will “wash out” the inmates’ suit to close the prison. Schwartz is hearing the suit now, but isn’t expected to make a ruling for several months.
Should he find that the “legislature has abdicated its responsibilities [to the prison],” Schwartz warned, “then that has opened up a hole the federal court will have to fill.”
The state earmarked $2 million from a bond issue for Sussex prison renovation, but the base construction bid opened in January was $2.8 million. With alternate improvements officials want, the cost would rise to $3.4 million.
Acting Correction Commissioner Paul Keve, a defendant in the inmates’ suit, said it “looks very hopeful” that $1.6 million originally appropriated for another prison project will be reallocated to the Sussex work….
Several times yesterday, Schwartz expressed puzzlement over the state’s defense to the suit which seemed to be, “Yes, Sussex is bad, but we’re going to improve it,” the judge remarked.
The improvements are part of the defense, replied Deputy Atty. Gen. John Willard. But he said he would also contend the prison’s deficiencies aren’t an unconstitutional denial of due process or cruel and unusual punishment, as the inmates claim.
The prison’s 45-year-old main building “defeats efforts to improve it in a superficial way,” Keve said, and demands instead a “drastic, complete, comprehensive” renovation.
He said a new kitchen is most urgently needed, but the plans also call for complete replacement of the plumbing, electrical and heating systems, construction of a gymnasium, medical-dental suite and space for classrooms and group discussions.
Prisoners have complained of a lack of rehabilitation programs….

Woman, baby, dog rescued from burning home
Mary Anderson … and a year-old baby were carried from the burning house at 4 W. 12th St. in Wilmington this morning. …
The fire, which originated in the chimney of the house, caused a spectacular blaze that destroyed the roof and damaged the interior of the dwelling, and drew a large crowd.
Trolley traffic on Market Street was tied up for 20 minutes or more. Long lines of cars from the Boulevard, Washington, Shellpot and Darby lines blocked both tracks for two squares or more, owing to the lines of fire hose that were stretched across Market Street.
The fire was first discovered by Mrs. Anderson who was in the house with the year-old baby of Margaret Thomas who was at work. Smelling smoke, Mrs. Anderson went to the second floor and seeing a flame around the stove pipe hole in the chimney, threw water on it. Thinking she had extinguished the fire, she started downstairs.
In the meantime, the blaze broke out around the edge of the roof and the smoke was seen by John Wright and Stanley Pletuszka, who were in the office of the Pittsburg Independent Oil Company at 12th and Market streets.
Wright ran to the fire alarm box at 13th and King streets and turned in an alarm to which Engine Companies 1,7 and 10 and Truck Company 1 responded.
Pletuszka ran to the house where he was joined by Lloyd Smith of West 13th Street. Finding the door fastened and knowing that Mrs. Anderson and the baby were in the house, they broke down the door.
They met Mrs. Anderson coming downstairs and when an attempt was made to get her to leave, she refused, insisting that the fire was out. The rescuers had to carry the woman from the burning building, then returning they found the baby in the lower part of the house and carried it to the home of a neighbor where the baby and the woman were cared for.
Herbert Johnson, son of Mrs. Anderson of Orange Street, hearing that his mother’s home was on fire, hurried there and with other men saved practically all of the furniture in the house. A small dog, owned by Mrs. Anderson, was rescued by Johnson, but a larger dog defied the efforts of other men to take it from the house. …
The firemen prevented the spread of the fire by deluging the building with water, the chemical streams first used being found insufficient to check the fire. …
The loss is estimated at $800.

RADNOR, Pa. – Authorities say a Delaware County school employee is accused of traveling to Texas to sexually assault a minor he met online.
What we know:
Michael Robinson, 43, was taken into custody near Radnor Middle School where investigators say he worked as a paraprofessional.
Investigators believe Robinson traveled to Tyler, Texas in the summer of 2024 to meet a minor he had connected with online.
Robinson, according to U.S. Marshals, allegedly sexually assaulted the teen over the course of a weekend.
Delaware County school employee accused of sex assault of minor in Texas
Prosecutors in Smith County, Texas charged Robinson in December with Aggravated Sexual Assault of a Child Under 15-years-old.
Robinson is being held at a Delaware County jail where he is awaiting extradition to Texas.
What they’re saying:
U.S. Marshals in Pennsylvania said Robinson’s arrest shows that “sexual predators will always be pursued relentlessly.”
The Radnor Township School District said Robinson has been placed on leave and will not have contact with students.
“Parents of the limited number of children to whom the employee was assigned were contacted by the administration immediately.”
The district said it is cooperating with law enforcement and has “no information indicating misconduct involving district students.”
