Do you do that n -house or send it out? Please make sure the previously requested tests are using fathead <br />minnows as well. <br />Also, any news on the cyanide) analysis? <br />Thanks, II�INII�IlN1111161111N1I11�111�I�InI�I�IINll611 <br />Frim <br />720-69868 Chain of Custody <br />*Note New Contact Info" <br />Tim J.

This sample matrix is no amenable to analysis by 1010 or 1020 which are for liquids only. <br />For characterization of waste, t procedure is to apply a flame to the sample for --1 second and observe if it ignites and <br />burns vigorously. It does not. <br />However, for exposure to heat nd Flame, if held to the flame for a longer period the material will ignite and bum on its <br />own. <br />Since ignitability 7.1.2 was the rtquested test, the sample should have been reported as NOT Ignitable. Revise the report <br />to indicate this. I will revise the SOP to better differentiate between these two methods. <br />Dimple Sharma <br />Senior Project Manager <br />TestAmerica <br />1 <br />Page 5 of 6 <br />2/3/2016 <br />U P_005987 <br />
