XR-88TM PRESSURE WASH TEST RESULTS

Pressure wash water samples taken from a holding tank at CSR Marine in Seattle, Washington on March 29th, 2010 were put into containers given to WI Environmental by ALS labs in Everett, Washington. One sample was the raw pressure wash water, while the other was pressure wash water that was collected and then treated with WI Environmental’s XR-88TM.

The samples were then given to a lab representative that same day at 2:15pm for testing of heavy metals – including copper, lead and zinc. Those times and dates are to verify that the sample went straight from WIE to the lab, with no tampering between delivery and reception.

The samples were then given to a lab representative that same day at 2:30pm for testing of heavy metals – including copper, lead and zinc. Those times and dates are to verify that the sample went straight from WIE to the lab, with no tampering between delivery and reception.

ALS is a lab accredited by the State of Washington, and must pass ‘blind samples’ twice a year to maintain its accreditation. The lab also maintains tight quality control on an internal basis to ensure that instruments are properly calibrated and that no cross- contamination occurs.

ALS uses EPA specified testing methods for pressure wash water, using ICP-MS, (Inductively coupled plasma mass spectrometry) widely acknowledged as the premier technology for trace metals analysis. The pressure wash water samples were tested April 1st, 2010.

In the first sample, before treatment with WIE’s XR-88TM, the raw CSR pressure wash water sample showed the following:

  • 11,000 parts per billion of Copper
  • 190 parts per billion of Lead
  • 2,200 parts per billion of Zinc

In the CSR pressure wash water sample after treatment with XR-88TM, lab results showed the following:

  • 21 parts per billion of Copper
  • Non-detectable amount of Lead
  • Non-detectable amount of Zinc

Pressure wash water for boatyards can either be recycled, or put into the sanitary sewer system so it doesn’t go into waters of local lakes or Puget Sound.
