Problem-first

    By Challenge / Contaminant

    Start from the contaminant: PFAS, heavy metals, COD/BOD, pathogens, scaling, and more.

    Challenge pages group providers by the specific contaminant or problem they solve. Start here when the brief is 'remove X' rather than 'build Y'.

    What you'll find here

    Sometimes the problem comes first. Start from the contaminant, not the plant.

    You don't always need 'a membrane plant'. You need arsenic below the limit, PFAS destroyed, or a cooling tower that stops scaling. These pages connect you with providers whose core expertise is a specific contaminant or failure mode: PFAS, heavy metals, COD/BOD, oil & grease, arsenic, trace pharmaceuticals, scale, corrosion, nitrate, ammonia, color, microplastics, silica, phosphate, biofouling, odor, and more.

    • Forever chemicals: PFAS removal and destruction

    • Heavy metals, arsenic, iron, and trace organics

    • COD/BOD, oil & grease, and high-strength effluents

    • Scale, corrosion, biofouling, and odor control

    Who this is for

    Best fit if you're working on

    The providers in this group tend to have the strongest track record in these contexts.

    • Compliance-driven upgrades
    • Contaminant-specific RFPs
    • Sites with a known failure mode
    • Teams solving for discharge limits
