Insights & guides

Arsenic removal from stormwater depends on whether the arsenic is dissolved or particulate. Here is how to tell, which media targets it, and how to choose a format.

Why is there iron in stormwater? Soil particles and corroding steel put it there. Here is how to trace it at your site and what treatment fits each fraction.

How to add a targeted polishing step after your existing treatment so the final effluent meets a discharge or reuse limit, and how to match media, format and testing to the pollutant.

Outfall hydrocarbon capture works best as the last barrier, not the only one. Compare outfall, inlet and surface capture, and see what decides the choice.

Phosphorus removal without chemicals runs on biology in sewage plants and on sorptive media in stormwater. Learn which fits your discharge and what each leaves open.

A stormwater bill funds the public drains, basins and permit work that manage rain runoff. See how it is set, why it differs from sewer charges and what it leaves to private sites.

Floating hydrocarbon booms use oil-attracting media to intercept fuel sheen at the water's surface before it spreads from fuel docks, slips and outfalls into open water, giving marinas, ports and permit holders a documented line of defense for discharge compliance.

Marinas limit fuel dock spills by pairing an SPCC-driven prevention plan with passive hydrocarbon capture at the dock, outfalls and catch basins — before sheen reaches open water.

A stormwater inspector checks your BMPs, outfalls, records and signs of illicit discharge against your SWPPP. Here is what the walkthrough covers and how to prepare before the inspector arrives.

Planning influent and effluent sampling for a stormwater treatment pilot means fixing sampler locations, choosing grab or composite methods, and defining how percent removal will be calculated before the first storm arrives.

A stormwater BMP reduces NPDES pollutant load only if it targets the specific contaminant fraction named in the permit. Here's how permit holders match media to metals, bacteria, phosphorus and PFAS without over-building the system.

PFAS stormwater filtration relies on media engineered to bind dissolved PFAS compounds as water passes through, and Abtech Industries builds that capture into formats sized to the site's catchment and discharge requirements.

Choosing stormwater filtration media starts with naming your contaminants and their dissolved or particulate fraction, then matching flow rate, format and maintenance access to your permit's reporting needs.

Phosphorus removal in a catch basin takes a media built for the dissolved fraction. See how Smart Sponge® HM sits in an Ultra Urban® Filter and where the approach stops.

A catch basin insert filter is a device fitted beneath a storm drain grate to intercept pollutants before they leave the inlet. Here is what it captures, how to judge fit and bypass handling, and what drives maintenance.

PFAS removal from stormwater relies on sorbent media that binds the compounds as water passes through, paired with a format matched to the site's flow and infrastructure. Here's how the mechanism works, what affects performance, and how to verify results before full-scale deployment.

Drop inlets and catch basins both collect surface runoff, but only one holds sediment in a sump — a distinction that changes what treatment and maintenance a stormwater permit requires.

A stormwater pit or catch basin collects runoff before it enters the storm drain, and a filter insert added to that basin can target sediment, debris and dissolved pollutants before specifying one, check pit size, flow capacity, maintenance access and media replacement needs.

Catch basin retrofit stormwater treatment lets permit holders add pollutant capture to existing storm drains without excavation. Here's how to decide when it fits and what to check once it's installed.

A stormwater management system is made up of capture, conveyance, pretreatment, treatment, storage or infiltration, and discharge — and choosing where filtration media belongs depends on the pollutants, the site constraints, and the permit driving the work.

Metal fabrication stormwater exceeds NPDES heavy metal benchmarks because dissolved zinc, copper, iron and arsenic wash off galvanized surfaces, scrap and grinding debris, and sediment controls alone cannot trap them.

A drop-in stormwater drain filter is chosen by matching the media to your site's contaminants first, then fitting the format to the catch basin itself. Here's how that selection process works, from site assessment through install.

A deck drain insert has to do more than trap leaves and grit — its media has to bind hydrocarbons, dissolved metals, phosphorus or bacteria while still passing flow during a storm. Here's how to judge media type, drain fit, bypass behavior and maintenance access before choosing one.

A passive stormwater treatment retrofit works when the media is matched to the site's pollutant profile, flow, existing inlet structures and permit targets — not the other way around.

Catch basin insert cleaning frequency depends on site conditions, not a fixed calendar date — here's what actually drives the interval and how permit holders set one that holds up.

An NPDES permit stormwater BMP is any structural or non-structural control a permit holder uses to reduce pollutants before discharge, and inspectors expect it to match the pollutants named in that permit.

Marina stormwater BMPs need to match the pollutants found at fueling docks, boatyard wash areas and deck drains — this guide breaks down source controls, spill response and drain-level filtration by zone.

Planning access for stormwater filter cartridge maintenance means working through the vault location, lid type, confined-space needs, equipment positioning and cartridge handling before a crew ever shows up.

A hydrocarbon filter for storm drains works by binding oil and fuel sheen inside the catch basin, before dissolved and floating contaminants ever leave the site. Here is how that treatment fits into a permit holder's compliance plan.

Recycling facilities reduce heavy metals in stormwater by pairing source controls like covering and sweeping with structural and filtration BMPs that target the dissolved fraction sediment control leaves behind.

Total phosphorus and orthophosphate measure different things in stormwater, and the fraction driving a benchmark exceedance determines whether sediment controls or dissolved-phosphorus media are the right fix.

How Smart Sponge® Quanta™ targets dissolved PFAS in stormwater and wastewater, how it's tested and deployed, and how it fits alongside Abtech's other contaminant-specific media.

Bulk Smart Sponge® media loads into existing vaults, pressure vessels, tanks and skids to target dissolved metals, phosphorus, bacteria, hydrocarbons and PFAS without a full system replacement.

Zinc and copper removal from industrial stormwater depends on treating the dissolved fraction. See where the metals originate and which Abtech format fits each discharge point.

A permit-holder's comparison of how sorptive media like Smart Sponge® HM treats dissolved phosphorus differently than sand filters and bioretention media built mainly for particulate capture.

Oil and grease action levels under NPDES and MSGP permits often signal a broader dissolved-pollutant problem. See why sediment control alone falls short and how Smart Sponge® media targets hydrocarbons, metals, and bacteria at the catch basin.

A practical, question-led look at how Ultra Urban® Filter catch basin inserts and Smart Sponge® media address heavy metals, bacteria, TSS and other stormwater pollutants under NPDES and MS4 permits.

A phosphorus benchmark exceedance under NPDES or MS4 permits calls for a documented corrective action — source tracing, fraction analysis, and a matched BMP — not just a new filter. Here is the sequence from lab result to installed treatment.

Total metals and dissolved metals measure different things on a lab report, and the gap between them explains why sediment control alone often fails to move an NPDES or MSGP benchmark exceedance for zinc, copper, or lead.

Phosphorus removal from stormwater means treating both the particulate and dissolved fractions. See how Smart Sponge® HM targets dissolved phosphorus and metals, and where in the drainage chain to place it.

Metal recycling facility stormwater treatment starts with identifying where zinc, copper, lead, and iron enter runoff, then placing Smart Sponge® HM media at the catch basin to target dissolved metals before they reach the outfall.

Sources of phosphorus in stormwater include fertilizer, organic debris, sediment and industrial residues. See how particulate and dissolved fractions differ and how Smart Sponge® HM targets both.

What causes heavy metals in stormwater comes down to the surfaces runoff crosses before reaching a catch basin — metal fabrication, recycling yards, and roadways each load zinc, copper, lead, and arsenic differently, which shapes how permit holders treat for it.

Bacteria removal from stormwater requires treatment matched to E. coli, fecal coliform, and enterococcus specifically — sediment control alone does not stop pathogens from reaching a permitted outfall.

Bacteria pass through sediment traps and standard filters untouched, so MS4 and NPDES permit holders need a control that targets the microbes directly.

Oil, grease, and fuel are among the most common pollutants in urban runoff. Learn where stormwater hydrocarbons come from and how to filter them at the catch basin.
