Case Studies

Proof in Practice

A small set of representative projects: the diagnosis-first chemistry that turns a recurring problem into a durable, budgetable outcome. Senior work, done directly by the scientist doing the analysis.

A note on confidentiality. These cases are anonymized by default (client type and region, not names) and describe methods at a level that shows the approach without publishing a playbook or specific dosing. Named versions with full data are available on request where the client has approved release.

Proactive Phosphorus Inactivation, Urban Swimming Lake, Northern California

Challenge Recurring late-summer cyanobacteria closed a popular urban swimming lake most seasons, and prior phosphorus-binder treatments delivered only short-term control.
Approach Sediment phosphorus diagnostics to size the mobile pool, then a combined phosphorus-binder inactivation applied proactively before bloom onset, weighted spatially toward the shallow high-release zones.
Outcome Reduced bloom frequency and intensity; proactive seasonal timing replaced in-season crisis response and kept the swim season open.
Why it mattered Converted an annual emergency-treatment cycle into a planned, budgetable program, and protected public access.

High-Efficiency Binder Dosing in Cold Water, Small Urban Lake, Northern California

Challenge A shallow, algae-prone urban lake kept re-blooming after prior low-dose binder treatments that never fully addressed internal loading.
Approach Lake-chemistry-driven selection of a higher-efficiency binder formulation, dosed in a cold-weather window to minimize toxicity risk and cut applied volume per unit of phosphorus removed.
Outcome More effective phosphorus removal than prior treatments at lower applied volume, with cold-water timing reducing aquatic-toxicity risk.
Why it mattered Showed that formulation and timing, not simply spending more, decide whether an inactivation holds.

Lake Management · Sediment Phosphorus Anonymized

Zone-Targeted Phosphorus Control in a Tidal Lagoon System, Coastal California

Challenge An enclosed, tidally influenced lagoon accumulated phosphorus across its basins, with a real risk that treatment could re-release phosphorus if treated zones went anoxic.
Approach Sediment phosphorus release mapping to rank basins by risk, an iron-based binding design, and a staged application sequence built around the anoxic re-release risk.
Outcome A zone-specific plan that prioritized the highest-risk basins and built re-release risk directly into the protocol, reducing the chance of cross-basin problems.
Why it mattered Avoided a one-size-fits-all dose that could have back-fired in a chemically complex, brackish system.

Lake Management · Hypolimnetic Oxygenation Anonymized

Oxygenation Performance Evaluation, Large Urban Tidal Lake, California

Challenge Hypolimnetic anoxia in a large urban tidal lake drove internal phosphorus release and low dissolved oxygen, feeding blooms with public-health and wildlife impacts.
Approach An oxygenation-system performance evaluation using treated-versus-control station comparison and ON/OFF period analysis, plus an early-warning indicator tied to a measured turbidity lag.
Outcome Roughly a third lower chlorophyll-a in oxygenated zones versus control, and a ~2-week early-warning trigger for oxygen depletion, documented as the basis for an expansion decision.
Why it mattered Gave the operator defensible evidence for whether and where to invest in expanded oxygenation.

Why a boutique gets you this

Senior-only

Every deliverable is done by a PhD principal. Your budget buys the expert directly, not junior hours supervised at a distance.

Fast & responsive

No layers, no hand-offs, no change-order machinery. A direct line to the person doing the work.

Lower overhead

No tower of billable middle management. Pound-for-pound more technical output per dollar.

Niche depth

Lake and reservoir biogeochemistry. A narrow focus is exactly why the work goes deeper than a generalist's.
