The City of Hood River has levied a second fine against Luhr Jensen and Sons in as many months for dumping heavy metals into the wastewater treatment system.

On Tuesday, the waterfront company was fined $2,000 for discharging silver into the system and then failing to report the incident in a timely manner. That fine follows an $8,000 penalty in February after sampling reports showed that more than 100 times the allowable limit of chromium, copper, lead, mercury, nickel, silver and zinc were released from the plant on Dec. 26, 2001. The latest discharge inundated the system with more than 38 times the acceptable level of silver, according to Mark Lago, director of public works/engineering.
