Radon Testing and Reporting Plan
 
 

November 29, 2016

 
 

In 2015, ORS 332.166-167 placed the requirement for all school districts to develop a radon testing and reporting plan.  That plan included the requirement to initiate radon testing of district buildings on or before January 1, 2021.  North Clackamas School District is committed to providing a safe environment for students and staff.  With that commitment in mind, the district has engaged an independent testing firm, PBS Engineering & Environmental (PBS), to conduct radon testing.  Testing has been initiated in all district buildings in the last month, four years prior to the State deadline.

 

Radon is a naturally occurring radioactive gas that enters from the soil beneath buildings (such as schools and homes) through cracks and openings in the foundation. The United States Environmental Protection Agency (EPA) recommend reducing the concentration of radon in indoor environments to below the Radon Action Level of 4.0 pCi/L (radon is measured and reported in picocuries per liters of air or pCi/L).

 

On November 7, 2016, test results were received for 21 of the 39 locations tested.  These results included 686 samples, with 27 rooms testing above the action level of 4.0 pCi/L (24 results between 4.0 and 8.0 pCi/L and 3 results above 8.0 pCi/L).   

 

For the following locations, all samples tested below the action level of 4.0 pCi/L:

Ardenwald Elementary

Clackamas Middle College

Land Lab

Linwood/Sojourner Elementary

New Urban High School

Oak Grove Elementary

Rex Putnam High School

     View Acres Elementary

 

Whitcomb Elementary

Wichita Community Center

Administration Building

Former Administration Building

Concord Elementary

Warehouse

Transportation

Facilities

 


Following are the buildings with rooms that tested above the action level:

 

Milwaukie/El Puente Elementary - Room 6 and Storage Room

     Riverside Elementary - Staff Work Room

     Rowe Middle School - Rooms 216 and 217

     Campbell Campus  - Room D4

      Bilquist Elementary* - Conference Room (103), Nurse's Office (105), 108, Staff Room, 117, Media Center Office (124), Custodial Room (171), Cafeteria, Media Center, Occ. Therapy Room, Production Room, Reception and Stage Area, Classroom 22, 23 and 24
    
  * The independent lab recommended Bilquist be retested.   As a result of their questioning the test results, the district discovered the tests may not have been conducted in compliance with EPA protocols resulting in inaccurate results, particularly in the three classrooms.  Corrective actions have been taken and retesting will be completed to assure compliance with EPA's guidelines and accurate results.
 

The district will follow EPA guidelines, as outlined in the district’s Radon Testing and Reporting Plan, to address the actionable results.  Specifically:

 
  • Where the result is between 4.0 and 8.0 pCi/L, the district will perform a follow-up measurement of that room using a long-term test.  This test will be conducted over as much of a nine-month school year as possible, when rooms are likely to be occupied.  If that result is equal to or greater than 4.0 pCi/L, the district will investigate and implement options for lowering the radon level in that room.

  • Where the result is above 8.0 pCi/L, the district will conduct a second short-term test within 30 days.  The two results will be averaged, and any room where the average is equal to or greater than 4.0 pCi/L, the district will investigate and implement options for lowering the radon level.

Lowering radon levels can be as simple as increasing the time the school’s ventilation system is operating or opening vents in crawl spaces.

 

The results for the individual schools can be found at: www.nclack.k12.or.us/radon.

 

As you communicate with others, having accurate information about radon at your fingertips is important.  You can find resources here:  www.nclack.k12.or.us/radon.

 

We will continue to provide updated test results as they are received and update the district website at www.nclack.k12.or.us/radon.
