Updated Analysis of Drinking Water Samples
Montgomery County Public Schools
The following are the current results of the continuing analysis of water taken from all
sources within a sample of public schools in Montgomery County. The high samples include
remote sites (such as sink faucets) and not designated drinking water sources. The results for
hallway water coolers are included as a separate data list of water sources most readily used by
students.
All results are for water samples taken straight from water sources without implementing
the mandatory water flushing of 15 minutes every four hours for water coolers and 60 seconds
every four hours for other water sources. Water flushing is required in all schools, unless
otherwise authorized by the Montgomery County Health Department, as indicated on the list
below.
The continued analysis of test results for the remaining schools and facilities is ongoing
by health department and school system staff. The entire process is following protocols
recommended by the U.S. Environmental Protection Agency. The action level standard is a
water sample in which the level of lead content is greater than 20 parts per billion (ppb). This
list will be updated as new testing results are released.
