Operations and water quality were unaffected following Saturday afternoon's spill of aqueous ammonia from a broken instrument probe that initially threatened residents near a Santa Clara Valley water treatment plant, officials said.

Authorities lifted the shelter-in-place warning at about 2:15 p.m., after crews sealed a leak on a 5,000-gallon holding tank at the Santa Clara Valley Water District's Santa Teresa plant, San Jose fire Capt. Steve Forman said.

The fire department's hazardous materials team responded at about 11:15 a.m. to reports of a leak at the plant, and the warning was issued at about noon after crews discovered about 250 gallons had spilled from the tank, Forman said.

The warning applied to residents of Graystone Lane at Via Santa Teresa; Rosalind Lane; Skuse Court; and Carriage Hill Drive.

The San Jose Police Department notified about 25 residences door-to-door during the warning.

The spill was contained shortly after the warning was issued, and firefighters turned over cleanup efforts to the hands of Santa Clara Valley Water District at about 3 p.m., Forman said.

The Santa Teresa plant is currently shut down for construction and maintenance.

No injuries were reported.
