Protocols For General Use Campus Buildings
The testing protocol for PSU includes all buildings but with priority given to buildings constructed prior to 1990.
Each building is sampled from a representative number of drinking water fixtures depending on the size of the buildings, total drinking water sources, and history of sampling results. The sampling locations within the buildings rotate over time.
In order to help address potential contamination before lead levels reach the MCL of 15 ppb, PSU requires response and repair actions when lead testing results are above 13 ppb.
In the event lead content above 13 ppb is achieved, the water source may be turned off and signs placed to indicate it is out-of-order. Corrective actions will be initiated to identify and replace the lead source. Additional sampling will be performed to determine if lead levels have been reduced to 13 ppb or lower.
Once periodic testing has yielded results from multiple floors and quadrants with acceptable lead levels, frequency of sampling may be reduced to a period of every 5 years.
