Livingston engineering outlines $27M SRF bid and well-treatment plan to address TCP and arsenic

City of Livingston engineering staff on May 6 presented a multi-year plan to expand centralized treatment for 1,2,3-trichloropropane (TCP) and arsenic removal, including ongoing construction at Well 8A, test-well results at Lucero Park (Well 18) that showed TCP presence, and an SRF funding application for $27 million that would cover two centralized TCP treatment projects.

The presentation mattered because the projects are intended to bring treated water into compliance with state drinking-water rules and because some federal ARPA funds earmarked for treatment equipment must be spent by December 2025. Engineering staff said those deadlines and grant windows affect procurement and construction sequencing.

Engineering staff said Well 8A is under construction with an estimated cost of “around $4,000,000.” Nick, an engineering department staff presenter, said the city is proceeding with multiple centralized treatment projects: a Killian-Park centralized TCP plant that would treat wells 12, 13 and 17 and another expanded centralized site paired with an arsenic treatment plant that would treat wells serving the same site. The city has applied for State Revolving Fund (SRF) support and is pursuing a $27,000,000 package the presenters said now appears to be a 100% grant in the current application rather than a mix of grant and loan.

Engineering staff reported that a test well drilled at Lucero Park (Well 18) in April showed TCP and minimal arsenic at deeper depths; staff said shallower intervals above about 400 feet showed much lower arsenic. Nate, another engineering department staff presenter, described that Well 18’s water will be piped to a…
