WANAQUE VALLEY REGIONAL SEWERAGE AUTHORITY

Copper discharge from Wanaque Valley plant hits 480% over limit in July

Copper violations at the Wanaque Valley Regional Sewerage Authority have swung sharply over the past year, and the most recent reading is the concerning part. The plant exceeded its permitted limit for total recoverable copper by 74% last September, 67% in December, then jumped to 178% over limit in March, and most recently hit 480% over its permitted limit in July, nearly six times what its permit allows. Copper is not like organic waste; it doesn't break down in water, and it persists in the system once discharged. At low concentrations it's toxic to aquatic life, damaging fish gills and interfering with the sensory systems fish and invertebrates rely on to navigate and detect predators. Those effects surface well before anything as visible as a fish kill, which makes this the kind of problem that can go unnoticed until it's advanced. A single bad quarter might be a fluke, but a reading nearly six times the permitted limit, following two quarters of sharp escalation, suggests something upstream of the plant's treatment process isn't being corrected, whether that's an industrial source feeding the plant or a treatment process falling behind. Direct water-quality sampling from the river near the discharge point wasn't available to confirm what's actually happening downstream, so at this point this is a compliance record rather than a measured ecological effect. It's also worth noting that across every discharger tracked in this watershed, including this one, the EPA's compliance summary shows zero dollars in penalties assessed to date, even as the most recent reading is the worst yet.
