NEW BRUNSWICK, NJ — Chemicals used to treat drinking water in the city are slated to cost almost $828,000 through next January.

At its Feb. 1 meeting, the City Council approved contracts with five companies to provide eight types of chemicals to the New Brunswick Water Utility. The total estimated price of the purchase runs about $30,000 less than last year’s tab, according to city documents.

“Our chemicals haven’t changed, and our consumption is pretty much the same as it was last year,” Water Utility Director Mark Lavenberg said last night.

The contracts require the five companies to both provide and deliver the chemicals.

The utility operates chemical feed systems to treat water, which is then distributed to customers in New Brunswick and Milltown, according to city documents.

Water plants began using at least one of the chemicals in this purchase, potassium permanganate, in greater volumes last year to combat the buildup of a contaminant that had showed up at “unusually high levels” over the summer. That resulted in a violation, according to the city.

Chemtrade Chemical Corporation of Toronto, Canada, will earn $354,573 for providing aluminum sulfate and sulfuric acid to the water utility, according to the agreement.

Univar USA of Pennsylvania will be paid $165,284 for providing the potassium permangante, which Lavenberg described as a “wonderful” tool, and another chemical.

Shannon Chemical Corporation, also of Pennsylvania, will receive $126,600 for providing citric acid.

JCI Jones Chemicals of Florida will be paid $115,600 for providing two types of chemicals.

Green Lime Company of West Virginia will earn $65,800 for providing hydrated lime, according to city documents.

The water utility did business with three of those companies—Chemtrade, Univar and Green Lime—last year.

Lavenberg recommended the five companies after a public bid.

While the total cost is less expensive than that of the previous year, it’s on par with what the city spent on water-treatment chemicals in 2015, according to city documents.
