Disinfection Byproducts (DBPs)

In Phase I (Project 3177), quantitative real-time PCR assays were developed to detect Group F ads in water.

Determine baseline occurrence of Legionella throughout the Passaic Valley Water Commission (PVWC) water distribution system.

March 1, 2018 – August 31, 2018 - During this first reporting period, the team held its first project advisory committee (PAC) meeting, the target opportunistic pathogens (OPs) were selected, and development of DNA extraction and quantitative polymerase chain reaction (qPCR) methods was initiated.

December 1, 2018 – February 28, 2019 - During this reporting period, the team started to examine how the developed methods for opportunistic premise plumbing pathogens (OPPPs) measurement will perform under real-world conditions, especially when evaluating effects of mitigation.

October 2017-March 2018 - The technique identified is the resistance measurement of a pipe.

January-March 2019 - After conclusive experimentation in the laboratory, testing in the field has begun. The equipment used for laboratory experiments was modified for usage in the field.

A comprehensive literature review was conducted in order to identify new technologies capable of discriminating the buried metals, a vendor investigation has been completed, and more.

The main focus of the project to-date has been monitoring the biological acclimation of pilotscale filters prior to evaluating alternative operating conditions.

The pilot began running in October of 2018 with the first set of three membranes: Toray HFS2020-N, Scinor SMT600-P50, and Scinor SMT600-P72.
