The Philadelphia Water Department provides integrated potable water, wastewater, and stormwater services for Philadelphia, Pennsylvania, and some communities in Bucks, Delaware and Montgomery Counties. [3]
The primary mission of the department is the planning, operation and maintenance of both the physical infrastructure and the organized personnel needed to provide high quality drinking water, and to provide an adequate and reliable water supply for all domestic, commercial, and industrial requirements, and to manage wastewater and stormwater to protect and improve the quality of the region’s watersheds, especially the Delaware River and the Schuylkill River.[3]
Drinking water
The Water Department draws about half of its water from the Schuylkill River, and about half from the Delaware River. The Queen Lane Plant in East Falls draws water from an intake pumping station (1895) on Kelly Drive. The Belmont Plant on Belmont Avenue in Wynnefield draws water from an intake pumping station (1870-1900) on Martin Luther King, Jr., Drive. [4] The Fairmount Dam prevents brackish water from the Delaware River from coming up the Schuylkill from the Delaware with the tide.[5]
Water Quality
In April 2011, Environmental Protection Agency (EPA) found elevated iodine-131 levels in Philadelphia's drinking water.[6][7] In response to the Environmental Protection Agency (EPA) findings, the Philadelphia Water Department posted a notice that Iodine-131 had been found in the water supply.[8] Iodine-131 is associated with the treatment of thyroid cancer,[9][10] nuclear energy, and is a popular radioactive tracer used in hydraulic fracturing fluid since the 1970s to determine the injection profile and location of fractures created by hydraulic fracturing,[11][12] [13][14] [15] The National Cancer Institute has reported that children exposed to iodine-131 may have an increased risk of thyroid cancer. [16] In the notice, the Philadelphia Water department attributes the presence of Iodine-131 to nuclear energy production and the March 2011 Japanese nuclear incident (Fukushima Nuclear Incident).
Iodine-131 was also found in the Wissahickon Creek, and at several sewage treatment plants along the creek near Philadelphia in late July 2011, long after the fallout from the Japanese incident would have decayed.[9][10] Historically, Iodine-131 had been found in several Philadelphia drinking water samples before. Environmental Protection Agency (EPA) records showed that Philadelphia's iodine-131 levels were the highest in the last decade in the set of those measured at 59 locations across the United States.[10] EPA records show readings above the acceptable limit of 3 pCi were recorded at Queens Lane Water Treatment Plant on three occasions and Belmont Water Treatment Plant on four occasions since October 2007. Levels are recorded 3-4 times a year. Readings at Baxter Water Treatment Plant were lower.[4] The EPA also found elevated levels of Iodine-131 in the water discharged from water treatment plants in nearby Ambler and Abington in April 2011.[17] The EPA is concerned about radionuclide levels in drinking water. In March 2011 the EPA asked the Pennsylvania Department of Environmental Protection (PDEP) to require "community water systems (CWSs) near publicly owned treatment works (POTWs) and centralized wastewater treatment (CWT) facilities receiving Marcellus Shale wastewater to conduct sampling immediately for radionuclides." They note that "in previous monitoring, radionuclides were not detected or were detected at levels less than one-half of maximum contaminant levels," but that "the CWS have not sampled after the introduction of Marcellus Shale operations." The EPA letter adds that "Discharges from these operations could increase radionuclide levels substantially."[18] In 2011, the US Environmental Protection Agency, Pennsylvania’s Department of Environmental Protection and the Philadelphia Water Department were working together to test surface water (rivers and streams) and discharge from water treatment plants. By June 2011, the EPA had ruled out hospital sources and the Fukushima Daiichi nuclear disaster as causes and were still trying to identify the source.[17] In July 2011, although no source had been identified, the Philadelphia Water Department was attributing the elevated levels to thyroid cancer patients' urine.[10]
Current Solution
Unable to locate and eliminate the source, the Philadelphia Water Department is upgrading its water treatment facilities and water management systems to better deal with the waste water. The water department plans to raise funds for the project by increasing Philadelphia residents' water and sewer rates over the next four years.[5] The warning about iodine-131 was still posted on the Philadelphia Water Department web site as of March 1, 2012. No contaminant levels have been posted on the EPA web site since April 2011.[8]
