3.0 ANALYTICAL AND TESTING PROCEDURES


Each full-scale UV system will be monitored for microbial parameters, chemical/physical water quality parameters, and operations/maintenance parameters. These parameters will be measured routinely according to the schedule provided in Section 3.5; most samples are collected on a daily, weekly or monthly basis. Additionally, quarterly sampling/monitoring will be conducted which will include 1) water samples to be submitted for DBP analysis, and 2) water samples to be submitted for microbial analyses following a spiking event (challenge) with MS-2 bacteriophage.

South Berwick Water District: Sample collection at the SBWD pilot test site will be conducted by UNH-ERG. All physical/chemical and microbiological water quality analyses will be the responsibility of UNH-ERG. Additionally, each quarter, for four quarters, a MS-2 bacteriophage challenge will be conducted at the SBWD pilot test site. The challenge event is described in Section 3.4 and includes spiking with MS-2 bacteriophage, and subsequently sampling and analyses for MS-2 bacteriphage. UNH-ERG will be responsible for all MS-2 bacteriophage analyses.

Indianapolis Water Company: Sample collection at the IWC pilot test site will be performed by IWC staff at the Indianapolis facility. All physical/chemical, coliforms, and heterotrophic plate count analyses will be performed by IWC staff; MS-2 bacteriophage and human enteric virus analyses will be performed by UNH-ERG. If the pilot test analyses overburdens the IWC laboratories, then UNH-ERG will take responsibility for the overburden. Additionally, each quarter, for four quarters, a MS-2 bacteriophage challenge will be conducted at the IWC pilot test site. The challenge event is described in Section 3.4 and includes spiking with MS-2 bacteriophage, and subsequently sampling and analyses for MS-2 bacteriophage. UNH-ERG will be responsible for all MS-2 bacteriophage analyses.

Section 3.1 provides the quality assurance/quality control requirements for sample collection and analyses. Sections 3.2 and 3.3 provide detailed sampling/monitoring and analysis procedures recommended for this project.

3.1 QUALITY ASSURANCE/QUALITY CONTROL REQUIREMENTS

The quality assurance (QA) requirements for the physical/chemical water quality measurements of this full-scale UV project are modified from Standard Methods for the Examination of Water and Wastewater (Standard Method 1020) (APHA, AWWA, WEF, 1995. All analytical laboratories involved in the project will be required to: 1) use either Standard Methods as indicated by this document, or follow procedures provided by this document 2) follow the sample control and documentation procedures provided in this sampling plan, 3) conduct and report calibration procedures, and 3) provide the PI with their respective internal procedures for data reduction, validation and reporting.

Standard Method 9020 should be followed for QA in all microbial work.

Quality control (QC) measures as specified in Standard Methods 1020B will be required for this project.

3.1.1 Sample Control and Documentation

Because this project involves multiple team members collecting samples and several different laboratories conducting analyses, it will be important to maintain sample integrity through careful sample documentation. This project will require that each team member responsible for collecting samples use a chain-of-custody (COC) form provided by UNH-ERG. The COC form is attached as Appendix A and requires

In addition, sample labels used should be gummed labels attached prior to sample collection. Each label should include the following:


The laboratory receiving the samples should keep a log book for sample receipt. The log book should record the following observations:
