Oak Ridge Elementary School Indoor Air Quality Timeline

• July 27, 2005 – HICAPS, Inc., Project Management firm for Oak Ridge Elementary School project, reported to Guilford County Schools (GCS) that mold was discovered on library books and the fabric of some chairs that had been stored during the summer in an unconditioned trailer. This was discovered as the books were being unpacked in the temporary library located in the new building. It was also noted there were suspicious spots on the carpet in two classrooms that were used near the end of the 2004-05 school session but not reported during that time.
  
  
• August 2005 - Site opened
  
  
• August 1 – 5, 2005 – A professional cleaning service, All-Kleen of Greensboro, N.C., was hired to clean the carpets in seven classrooms for bacteria remediation. This company also cleaned all the library books with an anti-microbial solution. No air testing was done at this time. GCS issued Purchase Order 42341 in the amount of $1,100.00 for this work.
  
  
• August 20 – 25, 2005 – All-Kleen was brought in to do additional cleaning after it was noted that some of the library books still had mold on them. During this period of time, the following work was performed:
• Classrooms 109, 110, 115, 116, 118, 120, 123, 613 and 625 were cleaned and sanitized
• The Storage Room was cleaned and sanitized
• The temporary Media Center was cleaned and sanitized (including all books; materials brought in from other classrooms; walls and ceilings)
• High Efficient Particulate Area (HEPA) vacuuming was performed in all of the administrative areas

The original GCS Purchase Order (42341) was increased $5,300.00 for this work.

• August 25, 2005 – The district received an e-mail from Guilford County Health Department (Alyson Best) that they had received two complaints about mold on library books.
  
  
• August 29, 2005 – Alyson Best with the Guilford County Health Department visited the school and reported that humidity was still high and mold would probably come back unless this was addressed.
  
  
• August 31, 2005 – The district received an e-mail from two parents concerned about mold issues at Oak Ridge
  
  
• September 1, 2005 – Alyson Best informed GCS that she had visited the school on August 31 and reported that the humidity seemed to have improved. She strongly recommended testing in all wings and was informed that GCS was going to get a Certified Industrial Hygienist to conduct testing. She reported that she heard several complaints from school staff about irritated eyes, throat, ears, headache, etc. She noted that elevated pollen levels were probably part of the reason for the complaints.
  
  
• September 2, 2005 – Air samples for fungal spores were collected in complaint areas by a Certified Industrial Hygienist with the Workplace Group, Greensboro, N.C. A report from the Workplace Group dated September 18, 2005 indicated “only one location (pre-K) detected any mold (a trace or few remnants).” The report noted considerable visible dust on inaccessible furniture surfaces, duct interiors and filters. Samples from inside the ductwork of several heat pump units that served the complaint areas detected no fungi. The unit serving the temporary media center had some visible dry buildup on the coil front of which culture detected some mold. This coil was cleaned immediately after this observation. All filters were later replaced with MERV 8 filters. Air samples collected on this date in classroom areas did not appear indicative of indoor fungi sources. Relative Humidity (RH) in a majority of the rooms measured exceeded 60% and were found to be in the 61% to 72% range with room temperatures in the 69 to 72 degree range.
  
  
• September 7, 2005 – Surface samples from supply air diffusers in administrative area detected no mold. Samples from interior duct at heat pump serving room 625 were negative for mold. Air samples from the media center and room 606 did not appear indicative of indoor mold sources. Dehumidification units were placed in administrative areas, additional air sampling was scheduled and HEPA vacuuming of dusty surfaces was recommended. See report from Workplace Group dated September 18, 2005. All-Kleen was authorized to perform HVAC cleaning; install portable dehumidifiers; clean carpets; vacuum dusty areas with a HEPA vacuum; wipe down rooms and treat with anti-microbial fogging. This work was performed at a cost of $12,025.00.
  
  
• September 9, 2005 – A letter was sent home to parents of Oak Ridge Elementary students to advise them of the Indoor Air Quality issues and the action the school district was taking. See draft copy of letter.
  
  
• September 9, 2005 – Ann Kraft, Oak Ridge Principal, was advised that copies of test data would be provided on-site so parents and staff could have access to the reports. Additional reports will be added when received.
  
  
• September 9, 2005 – Workplace Group reported mold results from classrooms had generally been “unremarkable.” Measurements for carbon dioxide (CO2) were made in a few complaint rooms. Room 503 had a level of approximately 1900 ppm, indicating outside air was not being supplied as designed. This initiated an effort to check all outside air damper settings. Additional carpet dust samples and air samples were collected in complaint rooms (either as follow-up or at a teacher’s request). Air samples were very low, not indicative of indoor sources. Carpet dust results were not yet available. A teacher in one of these rooms reported having severe allergy (rashes, etc.) to mold, but had experienced no such symptoms at the school.
  
  
• September 10 & 11, 2005 – All-Kleen performed work  noted in September 7 recommendation.
  
  
• September 15, 2005 – Workplace Group attempted to conduct CO2 measurements, but could not do so because many outside doors were open.
  
  
• September 16, 2005 – Following reports that outside air dampers had been checked, Workplace Group conducted additional CO2 measurements along with temperature and humidity. Several rooms indicated the possibility of less than ASHRAE recommended amount of outside air. Room 503 had not improved. Relative humidity in all but one room ranged from 62% to 72%. Room temperatures ranged from 69.5 degrees to 72 degrees F.
  
  
• September 18, 2005 – Report from Dave Smith, GCS Bond Program Director, on mold, CO2 and humidity issues at Oak Ridge.
  
  
• September 18, 2005 – A summary of the report from the Workplace Group Certified Industrial Hygienist indicated that testing results to date have not indicated the presence of significant mold issues in the classrooms or their ventilation systems, though systems filtration was found to be in less than desirable condition. Elevated humidity levels and lack of outside air are currently viewed as core components leading to environmental complaints at this school. It was recommended that additional evaluation be performed in response to area concerns. This included ventilation systems and humidity control. See report from the Workplace Group dated September 18, 2005 and accompanying laboratory test data.
  
  
• September 19, 2005 – Joe Hill met with Superintendent Grier and his Cabinet to provide an update on Indoor Air Quality issues at Oak Ridge.

• September 21, 2005 – Superintendent Grier sent Board of Education members an update on Oak Ridge issues. The update was posted on the GCS Web site in the Friday Notes (Sept. 22, 2005).
  
  
• September 22, 2005 – Received recommendation from the Workplace Group that carpet should be replaced in classroom 625 and the Health Room in the administration area and that these two spaces should not be used until this work was complete. Notified Ann Kraft of this recommendation.
• September 23, 2005 – Received e-mail about students with symptoms in Mrs. Church’s classroom. Request that additional testing be done.
  
  
• September 23 - 25, 2005 – Carpet was replaced in classroom 625. Carpet was removed from the Health Room and replaced with VCT – Vinyl Tile. All-Kleen provided filtration units to catch any dust created by the removal and installation.
  
  
• September 26, 2005 – The Oak Ridge Project Team meeting included a report of the action GCS was taking to address Indoor Air Quality issues. Present were GCS staff, architect, Oak Ridge staff, Oak Ridge Mayor, parents and two Board of Education members. See meeting minutes.
  
  
• September 30, 2005 – Received letter from the Compliance Bureau of the Occupational Safety and Health Division of the North Carolina Department of Labor concerning alleged health and/or safety hazards at Oak Ridge Elementary School. The alleged violations were stated as follows:
• The carbon dioxide levels are high (2000 & 5000 ppm) in Morton and Kramer’s classrooms
• Employees are exposed to mold in various areas/classrooms throughout the school, such as, but not limited to the media center, the “sick” room, Ms Gsell’s classroom, around the gym, etc. The media center was closed due to mold on the books. The level of mold in the “sick” room was so high that the carpet had to be changed. Some of the employees are experiencing respiratory problems.

A response was due by October 11, 2005

• October 6, 2005 – Received e-mail from Ken Carter with the Guilford County Health Department noting that his department continues to receive complaints from parents about Indoor Air Quality.  He also noted that a parent had stated that some children had a rash and expressed concern about the water supply. Wendy Gaither with the Health Department collected water samples for bacteriological and inorganic testing.
  
  
• October 10, 2005 – GCS responded to the North Carolina Department of Labor (NCDOL) notice of complaint. The response included a letter and test data from the Workplace Group.
  
  
• October 11, 2005 – A meeting was held with Oak Ridge teachers and staff to update them on test results and action GCS was taking to address issues. Staff was also briefed on the NCDOL notice of complaint and the response GCS provided.
• October 12, 2005 – Received letter from the North Carolina Department of Labor that stated: “Based on the information you have provided, OSHNC feels the case can be closed on the grounds that the alleged hazardous conditions have been corrected or no longer exist.”
  
  
• October 17, 2005 – School was notified that an independent HVAC engineer (Paul Levy) had completed testing and balancing of the HVAC system. This work was conducted over a period of several weeks. Follow-up carbon dioxide measurements were to be conducted by the Workplace Group beginning October 18, 2005.
  
  
• Late October, 2005 – Wendy Gaither with the Guilford County Health Department called to inform Dave Smith that tests for Radon conducted at the school indicated no problem with Radon.
  
  
• November 2, 2005 – Test results received for CO2 monitoring in 14 classrooms. Ten classrooms were within normal range and four classrooms had slightly elevated CO2 levels with the highest reading at 1534 ppm. The HVAC engineer was informed of these results so he would increase the amount of fresh air in the four classrooms.
  
  
• November 5, 2005 – GCS was informed that the mechanical contractor would install 8 additional return air dampers in order to increase outside air delivery to classrooms with elevated carbon dioxide levels.
  
  
• November 7, 2005 – Wendy Gaither with the Guilford County Health Department called to inform the district that preliminary tests of the water supply showed that “all results were found to be within normal ranges.” Test results were to be reviewed and certified at the state level.
  
  
• November 28, 2005 – Paul Levy, HVAC Commissioning Engineer, informed GCS that several Heat Pump units had “tripped out” and were not running. He indicated this was the most probable cause of elevated CO2 levels in the rooms served by these units.
  
  
• December 2, 2005 – Additional carbon dioxide testing was conducted in 13 classrooms. Ten rooms were within acceptable ranges, two had slightly elevated levels and one (520) had a significantly higher level (2004 ppm), although well below the OSHA threshold of 5000 ppm. Tests indicate additional adjustment to the HVAC system was necessary in these three classrooms.
  
  
• December 12, 2005 – Additional carbon dioxide testing was conducted in 25 classrooms. This report indicated that levels in classroom 520 had been significantly reduced since the last report.
  
  
• December 20, 2005 – Test results were received from samples taken from the carpet in Ms. Church’s classroom that indicated a slight presence of non-airborne, common outdoor/garden type mold. An Industrial Hygienist from the Workplace Group indicated this did not pose any imminent danger; however, a decision was made to replace this carpet over the holidays.
  
  
• January 19, 2006 – Swab samples were taken from the back side of carpet tiles in three classrooms. Two samples indicated no fungi growth and one sample indicated some fungi growth that is consistent with moist conditions.
  
  
• January 23, 2006 – Carpet dust samples were collected for testing in six classrooms. Results indicated that the weight of dust in the carpets was higher than tests conducted in September 2005. The report indicates there are no regulatory standards for mold in carpet dust. The decision to clean should be based on whether allergy or similar complaints are associated with a given room.
  
  
• January 24, 2006 – A moisture test of the concrete floor slab indicated the moisture content was slightly higher than a flooring contractor recommends for carpet tiles.
  
  
• January 30, 2006 – A Project Team meeting was held to review construction issues.
