Chain of Custody/ Microbial Reporting Form Requirements

Microbial Reporting Form (MRF)  Conforms to the TCEQ’s Quality Assurance Proj ect Plan (QAPP) for drinking water compliance  S ubmitted with any bacteriological sample to an accredited laboratory for compliance with RTCR  S erves as the chain of custody by which TCEQ receives all compliance sample data  Review this form for completeness at the time of acceptance  Incomplete forms must be rej ected for insufficient information

*Labs and public water systems should be using this version (Form 10525, 08/ 2017) of the MRF unless other versions have been approved by the Quality Assurance S pecialist

Required Fields  PWS ID  PWS Name  County  Contact information  S ampler information  Name  License number (Community and Non-Transient Non-Community systems)  S ignature  Title

Required Fields  S ample Iced (Y/ N)  Temperat ure When Received  Relinquished and Received By (Name, Dat e/ Time)  If a courier was used, sections must be filled out  Incubat ion Dat e & Time  Laborat ory Informat ion S ect ion  Test ed By  Laborat ory Approval  Report ed t o Client  Test Method Used  Chlorine Check (Absent/ Present)

Routine S ample Reporting  Required Fields:  S ample Identification/ Location  Must mat ch S ample S it ing Plan (S S P)  Date and Time of Collection– Mark AM or PM  S ample Type – “Routine/Distribution”  Chlorine Residual – Mark F for free or T for total

Repeat S ample Reporting  Required Fields:  S ample Identification/ Location  Date and Time of Collection – Mark AM or PM  S ample Type – Mark only Repeat  S ample ID and date of the originating positive (ID assigned by lab)  Chlorine Residual – Mark Free or Total x x x 1.15 121 Example Rd 7:15 508123 05 05 09 09 18 x x x 5/ 8/ 18 7:20 1.25 508123 123 Example Rd Main Office x 05 05 09 09 18 x x 5/ 8/ 18 125 Example Rd 7:30 x 508123 x 05 09 05 09 18 1.24 x 5/ 8/ 18 G123456A 05 09 05 09 18 7:45 508123 0.0 5/ 8/ 18

Change Request Procedures

What changes can be made after sample has been analyzed?  Incorrect PWS ID# or Name  S ample sites must match sites listed on the PWS ’s S ample S iting Plan (S S P)  Month/ Y ear of Collection  Relinquished date and lab tested date must support changes  S ample Types  ONL Y compliance to compliance sample types (Routine/ Distribution, Repeat or Raw Well S amples)

S ample Types  Compliance S ample Types  Routine (Distribution) S amples  Repeat S amples  Raw Well S amples  Non-Compliance S ample Types  S pecial S amples  Construction S amples **A sample marked as a non-compliance sample can not be changed to a compliance sample after it is relinquished to the lab

Change Requests S teps  Corrections to the MRF can only be made by the sample collector who signed the original form  Labs cannot make any changes to the MRF once it is relinquished by the sampler  Draw a single line through the incorrect data, write the correct information and initial next to the correction  Write a brief statement of the change made somewhere in the margin of the ID” ) with a full signature and date of correction form (ex: “ corrected PWS  S ubmit the corrected form to both the TCEQ and the laboratory

Example Change Request for Incorrect PWS ID#

Reporting a Positive S ample to TCEQ

Reporting a Positive S ample  Report positive sample results as soon as the result is read  If lab approval is necessary before t he posit ive sample can be report ed, please ensure t hat lab approval is expedit ed  Posit ive sample result s read on t he weekend should st ill be report ed t he same day  Positive sample results should be reported to both the TCEQ and the system the day they are read  Please provide both the Microbial Reporting Form (MRF)/ Chain of Custody and Positive Result Report Form to the TCEQ  S ubmit via email: RTCRPOS @ t ceq.t exas.gov (Preferred)  S ubmit via fax: 512-239-3666

Repeat S ampling

Repeat S amples  A set of three repeat samples is required for each positive  One from the original sample location  One within five service connections upstream  One within five service connections downstream  1 raw well sample from each active well marked as “ Raw Well ”  Must be marked as “ Repeat” on Microbial Reporting Form  Collected within 24 hours after notification  Must include the originating sample ID and collection date 508123 5/ 8/ 18 508123 5/ 8/ 18 508123 5/ 8/ 18 508123 5/ 8/ 18
