Updated Analysis of Drinking Water Samples Montgomery County Public Schools

Transcription

1 Updated: December 10, 2004 Updated Analysis of Drinking Water Samples Montgomery County Public s 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.
