<br /> ' • On 24 March 2014, the ozone injection system was removed from the site and
<br /> sent back to the manufacturer for repairs and servicing;
<br /> • On 04 April 2014, an alternate ozone injection system was delivered to the site
<br /> and connected to the ozone wells on 11 April 2015;
<br /> • On 15 April 2014, before the ozone injection pilot test could be re-initiated, it was
<br /> ' determined that the alternate ozone injection system had a faulty boost air
<br /> compressor and could not be put on-line;
<br /> • On 24 April 2014, the alternate ozone injection system was removed from the
<br /> site and replaced with the original ozone system after it had been repaired and
<br /> serviced;
<br /> • On 02 May 2014, the ozone injection pilot test was re-initiated;
<br /> • On 03 June 2014, groundwater samples and geochemical parameters were
<br /> ' collected and measured from wells MW-1, MW-2A, MW-3A, MW-5A, MW-6B,
<br /> MW-7B, MW-8A, MW-9A, and MW-10 as required by the MRP;
<br /> • On 01 July 2014, geochemical parameters were measured from wells MW-1,
<br /> MW-2A, MW-3A, MW-5A, MW-6B, MW-7B, MW-8A, MW-9A, and MW-10 as
<br /> required by the MRP;
<br /> ' • On 04 and 05 August 2014, the third quarter 2015 semi-annual groundwater
<br /> monitoring event was performed. Additionally, geochemical parameters were
<br /> measured in wells MW-1, MW-2A, MW-3A, MW-5A, MW-6B, MW-7B, MW-8A,
<br /> ' MW-9A, and MW-10 as required by the MRP;
<br /> • On 04 September 2014, geochemical parameters were measured from wells
<br /> MW-1, MW-2A, MW-3A, MW-5A, MW-6B, MW-713, MW-8A, MW-9A, and MW-10
<br /> tas required by the MRP;
<br /> • On 02 October 2014, groundwater samples and geochemical parameters were
<br /> ' collected and measured from wells MW-1, MW-2A, MW-3A, MW-5A, MW-6B,
<br /> MW-7B, MW-8A, MW-9A, and MW-10 as required by the MRP;
<br /> t • On 02 October 2014, the ozone injection pilot test was terminated; and
<br /> • Between 02 May and 02 October 2014, the ozone system operated nearly
<br /> continuously with minor shut downs. The ozone injection system operated a total
<br /> of approximately 4,393 hours or 183 days during the pilot test; and ozone
<br /> injection was distributed almost equally between OZ-1 through OZ-8 during the
<br /> pilot test.

<br /> ' In June 2013, baseline groundwater monitoring and sampling was performed at the site
<br /> in accordance with the MRP. Tabulated results are included in this report. Additional
