DISTRICT OF COLUMBIA WATER AND SEWER AUTHORITY
5000 OVERLOOK AVENUE, S.W., WASHINGTON, D.C. 20032
February 24, 2004

EXTENSIVE SCHOOL WATER TESTING PROGRAM CONFIRMS LOW LEVELS OF LEAD IN DCPS SCHOOLS AND FACILITIES
(Washington, DC) The results of an extensive sampling and
analysis program conducted February 14 through February 19, 2004, by the
District of Columbia Water and Sewer Authority (DCWASA) in cooperation
with the District of Columbia Public Schools (DCPS) shows that the vast
majority of the DCPS and facilities have extremely low levels of lead in
the water provided by the DCWASA Water Distribution System. Every
occupied public school in the District was tested as well as
administrative and shop facilities.
The results show that 98.94 % or 744 of the total 752
samples contained either no detectable quantities of lead or levels
below the Environmental Protection Agency (EPA) "action level"
for residences of 15 parts per billion (ppb). Eight samples tested above
the 15 ppb threshold. The test procedure was capable of detecting over 2
ppb of lead.
"Given the widespread nature of the tests taken
throughout the District, and the fact that the tests showing elevated
levels were so isolated, this tells us that the lead levels in WASA's
main service lines to public schools and facilities have lead levels
well below the EPA acceptable levels," said Jerry Johnson, WASA
General Manager. "But no matter how isolated, any case where the
tests show higher lead levels is of concern. Where tests showed problems
with a small number of plumbing fixtures, DCPS has taken prompt action
to address the concern."
Seven hundred fifty-two samples were collected from 154
schools and school facilities identified by DCPS. The sampling
methodology called for 5 samples to be collected at each location -
three from drinking fountains and two from sinks. Water was run from
each fixture for ten minutes before sample collection to obtain a
"snapshot" of the water delivered by each building's internal
plumbing system. An additional 22 "first draw" samples were collected from randomly selected locations
to assess the contribution of plumbing fixtures such as faucets and
drinking fountains, and ALL of these samples yielded results below 15
parts per billion (ppb) of lead, with 11 of the samples below the 2 ppb
limit of detection.
The samples were analyzed for DCWASA by Martel
Laboratories JDS, Inc., of Baltimore, Maryland, a water quality
laboratory certified by the Maryland Department of Health and Mental
Hygiene for microbiological and chemical examination of drinking water.
Martel followed EPA-specified methods in conducting the analyses by
inductively coupled plasma-Mass Spectrometry. A full report containing
the results for each fixture sampled at each location is attached.
The eight locations with lead levels above 15 ppb and the
actions taken are summarized below:
- A drinking fountain at Douglass Academy at
Douglass, 2600 Douglass Place, SE, yielded a water sample analyzed at 43
ppb lead. The fountain has been removed from service for replacement by
DCPS. All other samples taken at Douglass Academy -- two other fountains
and two sinks -- that were tested at the same time yielded samples
testing below the 2 ppb level of detection.
- A sink in the Teacher's Lounge at Kenilworth
Elementary, 1300 44th St, NE, yielded a water sample analyzed at 109 ppb
lead. Use of this sink has been suspended by DCPS pending a review of
its condition. Bottled water is being provided for staff use. All other
samples taken at Kenilworth --three drinking fountains and one sink --
tested at the school at the same time yielded samples testing below the
2 ppb level of detection.
- A sink in Room 109 at Eliot Jr. High School, 1830
Constitution Ave., NE, yielded a water sample analyzed at 50 ppb lead.
Use of this sink has been suspended by DCPS pending a review of its
condition. All other samples taken at Eliot -- three drinking fountains
and one sink -- tested at the school at the same time yielded samples
testing below the 2 ppb level of detection.
- A cafeteria sink at Bell Multicultural Sr. High School,
3145 Hiatt Place, NW, yielded a water sample analyzed at 160 ppb lead.
Use of this sink has been suspended by DCPS pending a review of its
condition. All other samples at Bell -three drinking fountains and an
additional cafeteria sink -- tested at the school at the same time
yielded samples testing below the 2 ppb level of detection.
- A drinking fountain at Dunbar Sr. High School, 1301 New
Jersey Ave., NW, yielded a water sample analyzed at 22 ppb lead. The
fountain has been removed from service for replacement by DCPS. All
other samples at Dunbar were below the EPA residential action level of
15 ppb. Specifically, two sinks tested at the school at the same time
yielded samples testing below the 2 ppb level of detection, and two
other fountains yielded samples testing at 3.9 ppb and 10 ppb.
- A sink in the kitchen at H.D. Woodson Sr. High School,
5500 Eads St., NE, yielded a water sample analyzed at 110 ppb lead. Use
of this sink has been suspended by DCPS pending a review of its
condition. All other samples taken at Woodson -- three drinking
fountains and one sink -- tested at the school at the same time yielded
samples testing below the 2 ppb level of detection.
- A drinking fountain at Penn Center, 1709 3rd St., NE
yielded a water sample analyzed at 18 ppb lead. The fountain has been
removed from service for replacement by DCPS. All other samples taken at
the Penn Center --two fountains tested at the site at the same time
yielded samples testing below the 2 ppb level of detection, and two
sinks yielded samples testing at 2.8 ppb and 6.8 ppb, respectively.
- A sink in the cafeteria Ballou Sr. High School, 34014th
St., SE, yielded a water sample analyzed at 16 ppb lead. Use of this
sink has been suspended by DCPS pending a review of its condition. All
other samples taken at Ballou --three drinking fountains and one sink --
tested at the school at the same time yielded samples testing below the
2 ppb level of detection.
