River Road plant's oxygen-demand violations stretch past two years

August 10, 2026

The River Road wastewater treatment plant in Edgewater, New Jersey, has been out of compliance with its Hudson River discharge permit for more than two years running. EPA records show the facility exceeded its allowed limit for carbonaceous BOD5, a measure of oxygen-consuming organic material in effluent, in eight separate reporting quarters between March 2024 and July 2026, with overages ranging from 20 to 52 percent above the legal limit. The most recent quarter on record is still in violation. This is not a single bad quarter or a permit upset; it is a sustained pattern the facility has not corrected.

The stakes are tied to what BOD5 actually does downstream: the more oxygen-demanding waste that enters the water, the less oxygen is left for whatever lives in it. The receiving stretch of the Hudson is already listed as an impaired segment under the Clean Water Act, with a pollution budget, known as a TMDL, set for it in 2022. No dissolved-oxygen readings from a monitoring station below this outfall were available to check whether the plant's exceedances are actually driving that impairment; establishing that link would require direct DO data collected during the violation windows themselves.

What's confirmed is narrower but still notable: a permitted discharger has been over its organic-loading limit, on and off, for over two years, into a river segment the state already considers compromised. Groups like the Hudson River Foundation for Science and Environmental Research track water quality issues like this one across the watershed, and it's the kind of long-running compliance record worth continuing to watch.

Flowering dogwood feeds the spring insects

May 28, 2026

In the parks near the Upper West Side, the flowering dogwood stands in full bloom against the green backdrop of newly leafed trees. White bracts spread wide like cupped hands, each cluster holding dozens of tiny yellow-green flowers at its center. The air carries the faint sweet scent of nectar, a signal that draws insects from across the canopy and understory.The brown-belted bumble bee arrives with a low buzz, her body thick with the russet band that gives her species its name. She lands heavily on a dogwood flower cluster, her weight bending the branch slightly. Her tongue extends to reach the nectar hidden in each small flower, while pollen grains stick to the branched hairs covering her body. As she moves from flower to flower within a cluster, then from cluster to cluster across the tree, she carries pollen between the separate male and female flowers that make up each white display.This exchange feeds both partners in ways that ripple through the late spring ecosystem. The bumble bee stores nectar in her crop and packs pollen into the baskets on her hind legs, carrying protein and carbohydrates back to her underground colony where workers tend developing larvae. The dogwood receives the cross-pollination it needs to set the bright red berries that will ripen by late summer, feeding migrating birds when insects become scarce. Other native bees join the feast: smaller sweat bees that nest in the ground beneath the trees, and solitary bees that emerge from winter hiding places in dead wood and leaf litter. Beetles climb up from the forest floor, their movements slower but no less purposeful as they chew pollen and lap nectar from the accessible flowers.The dogwood's timing anchors this burst of activity. Its flowers open just as many insects complete their spring emergence, providing concentrated nutrition when other flowering trees have finished their brief displays. The tree blooms for only two weeks, but those weeks coincide with the peak demand from new bee colonies, emerging beetles, and the caterpillars of moths that will pupate in the soil below. Even the invasive spotted lanternfly, now established in these urban forests, feeds on the tree's sap, though it gives nothing back in return.Close your eyes and listen for the steady hum that fills the air around a flowering dogwood. The sound deepens and fades as bumble bees move between trees, punctuated by the higher buzz of smaller bees and the occasional rustle of a beetle navigating between flower clusters. When you open your eyes, watch how the white bracts catch and hold the filtered light beneath the canopy, each tree a bright anchor in the green understory.

Monarchs arrive as milkweed opens

June 24, 2026

Along the weedy margins of Brooklyn's open lots and park edges, the common milkweed is in full leaf now. The broad, paired leaves are a deep matte green, soft on the underside, and the plants stand knee-high or taller in the places where the soil has been disturbed enough to let them take hold. If you find a patch, look at the undersides of the leaves. You may already see what is coming.Monarchs are moving through the region in early summer, and the females are laying. Each egg is a single pale dot, smaller than a pencil tip, pressed to the underside of a milkweed leaf with a small amount of adhesive. A female may lay several hundred eggs over the course of a summer, but she places them one at a time, often one per plant, spreading the risk. When the egg hatches, in three to five days, the larva eats its own eggshell first, then begins on the leaf itself. Common milkweed produces a sticky white latex that contains toxic compounds called cardenolides. Most insects cannot feed on it at all. The monarch caterpillar can, and it sequesters those compounds in its own tissues as it grows. By the time it pupates, it is unpalatable to most birds. The milkweed's defense becomes the caterpillar's defense. The relationship is not mutual in the strict sense — the milkweed gains nothing from the monarch — but the monarch is entirely dependent on plants in this one genus. Remove the milkweed, and there is no workaround.In the same disturbed ground where milkweed grows, horseweed is coming up fast. Horseweed is a native plant, a tall and bristly annual in the aster family that colonizes roadsides, vacant lots, and any ground that has been scraped or compacted. It does not host monarchs. But later in summer, when it flowers, its small white heads will draw a range of small pollinators, and the monarchs that emerge from their chrysalises in August and September will need nectar sources for the long flight south. Horseweed and milkweed share the same ecological address: edges, gaps, disturbed ground, places that are not managed closely enough to be lawns but not wild enough to be forest. In a city like Brooklyn, that kind of ground is exactly where monarchs find what they need.The red milkweed beetle is already on the plants. It is a striking insect, bright red with black spots, and it feeds on milkweed throughout its life cycle. Like the monarch caterpillar, it tolerates the latex and accumulates the toxins. The large milkweed bug does the same, piercing the seed pods to feed on the developing seeds. A single milkweed plant in early summer can be carrying the eggs or larvae of multiple specialist insects at once, each one using the plant's chemistry in its own way. The common eastern bumble bee works the flowers for nectar and pollen without any of that chemical tolerance — it simply avoids the latex by working the open florets where the sticky sap is not exposed.

Eastern Cicada-killer Wasps at peak activity across city blocks

July 29, 2026

(Sphecius speciosus) are at peak activity across the waterfront and inland parks this month — 19 sightings since late June, with seven logged just in the past four days from Greenwood Heights and Prospect Park to the waterfront edge and Herbert Von King Park, including sightings along Joralemon Street and in Herbert Von King Park on July 28. These are North America's largest native solitary wasps, two inches long and formidable-looking, yet they rarely sting. Their midsummer timing is no accident: they emerge and hunt precisely when cicadas do, each female provisioning a single egg with a paralyzed cicada dragged back to her burrow.That sightings are turning up across this many city blocks — from Greenwood Heights to Prospect Park to the waterfront edge — points to the persistence of suitable ground. Sparse vegetation, sandy margins, and bare soil patches still exist here in sufficient patchiness for a native insect with strict nesting requirements to establish and forage.
