The first deliverable is an inventory, not a treatment.
The result is judged on a laboratory record and on instruments other people own. A program opens by agreeing, in writing, what would count as success.
The sequence
Four stages, and the third one is where it gets decided.
- Situation report The surface, its area and history, any analysis you hold, prevailing wind, exceedance record and who lives downwind. Sent to Alarivean through the contact form. It commits you to nothing.
- Desk assessment A written view on whether the surface is a candidate, which of the four surface types it behaves like, what has likely concentrated in it, what a control area would need, and where confidence is low. If the problem is upstream water allocation, you get that in writing before anybody mobilizes.
- Sampled control area A treated area and a matched untreated area, sampled on an agreed grid, with the protocol and the no-benefit endpoints fixed in writing beforehand. Air data is collected alongside, and water applied and energy drawn are metered, so the cost side arrives with the result.
- The standing subscription Scaled only against what the control area showed. The client subscribes to a condition of the ground — the toxic fraction inside a defined service zone, worked continuously and verified by sampling — delivered by a licensed service operator over a minimum subscription period, with reporting formatted for the regulator. The rig, the crew and the obligation to come back next quarter stay with the operator.
The protocol
What gets measured, and who agrees it.
The measurement has to be credible to a third party before the result is known.
The primary record is a laboratory one: samples lifted from a treated area and a matched untreated area, on a grid and at intervals agreed in advance, analyzed somewhere both sides accept. The endpoints are named before the first pass.
Air data goes in the file too, off monitors positioned by agreement, ideally on the network your air quality authority already operates. Where a surface or its wet margin releases hydrogen sulfide, that reading joins the record, because sulfide is a compound and compounds are what this duty acts on. PM10 is recorded because your authority records it anyway. It is context only.
Water applied and energy drawn are metered from the first day and reported, because in arid country somebody will ask. Neither figure is the result being sold. A third party reads all of it alongside the crew.
| Measured | Why it is in the protocol |
|---|---|
| Target compounds, treated area against control | The contracted result: a change in what the ground is made of, read by a laboratory at both ends |
| Metals fraction, at both ends | Elements sit outside what oxidation reaches, so the record is built to show them unchanged, sample by sample |
| Hydrogen sulfide, where a surface releases it | A compound, an oxidation target, and one California has published an ambient standard for since 1969 |
| PM10 at agreed monitor positions | Your authority already records it, and a shared instrument outweighs a private one |
| Water applied and energy drawn | The operating cost comes out of the same exercise as the result |
| Surface condition and crust integrity | A crust broken by one vehicle pass changes what the next sample from that grid square means |
The standing arrangement
The authority should be reading the record as the crew does.
The instruments that judge this work usually belong to somebody else already, which makes it the easiest duty in this family to put under continuous independent scrutiny. Every program is designed that way.
Which bodies depends on the site. The air quality authority whose exceedance record is at stake. The regional environment agency. An atmospheric or soil science group at a nearby university. The public health office that answers for the population downwind. They are engaged before the baseline opens and stay engaged while ground is worked.
They hold the working data itself: laboratory results, PM10 telemetry, water and energy as the meters record them, surface condition notes, at the same latency the crew sees it. Their own monitors and split samples are encouraged, and anything those produce belongs to them.
The operating company writes this into a program because of who lives downwind of a playa. Risk controls get run to best practice when a body with a duty to those residents is watching, and health and safety only outrank a mobilization schedule if somebody outside the contract can see them pull against each other.
Why the authority holds a copy
A results file held only by the contractor can be interpreted after the fact. Held by the authority as well, it is a record.
If a treated area comes back indistinguishable from the untreated one, that finding already exists somewhere the operator cannot revise it.
Who subscribes
Four clients, four different definitions of value.
Air quality and environment authorities are judged on exceedances and arrive holding a dust file. That file splits in two: how much material moves, and what it is made of. Movement stays with the measures they already run. Nothing is contracted to move a monitor reading, and a control measure their regulator has approved stays where it is. A subscription changes the composition of the material on that ground, the question the toxicology keeps raising and procurement has never had a line item for.
Site operators — mines, quarries, plants with evaporation ponds — already carry a dust obligation, a monitoring network and water carts on a cycle. They usually know their own assay in detail, so they are the fastest to scope. Their question is which part of it is organic, and whether that toxic share can be dealt with on the parcel, with no truck and no receiving site.
Water authorities with a receding body face the hardest version, because they usually manage the allocation that caused the exposure. Their exposed margin holds decades of return flow and discharge in a band of sediment now dry, with no credible date for water to cover it again. Refilling a lake is not on offer. Detoxifying the band it left behind is.
Responders, port states and terminal operators come to it from an incident instead of an accumulation. Recovery is their trade and stays theirs; the question they bring is what to do about the hydrocarbon chemistry left in sand, shingle and marsh once a stretch is released. That work is scoped on the released stretch, and the moment to settle how it would run is in the response plan, before anything is burning. What the assist covers is written the same way as the rest: a sampled control area, a protocol agreed in advance, and a laboratory both sides name.
All four get the same shape of agreement. It is no hire and no windy-season callout: a subscription to a stated condition of the ground across a stated service zone, running while the wind is still. Dust is seasonal. Accumulation is not. Return flow, precipitating salt and a moving shoreline add to the inventory in months when nobody watches a monitor.
A load worked continuously never reaches the state that forces an emergency response. Procuring only once something has visibly gone wrong means buying at whatever price urgency sets.
An incident does bring clients in who would otherwise have waited, and a program can start that way. It still starts as a subscription. Until the conditions that produced the event are gone, the responsible arrangement — and the cheaper one — is capability already present and ready to work a shore quickly, instead of capability assembled again the next time. What flexes for that work is the minimum subscription period, which is set to a shorter cycle than a basin-scale aquatic prosperity program carries. Its length belongs to the individual agreement.
A subscription ends on two grounds. Performance outside the spec written into the agreement, or a client who has served the minimum period and is not satisfied, for any reason and without having to give it.
Programs are contracted by a licensed service operator running Sophia Delta systems, which today is Alarivean, Inc. Sovereign and national-scale schemes can be delivered by that operator directly, carried through a venture with a local partner, or licensed out of Sophia Delta, and a regional gas supplier features in most of them. None is a purchase or a hire; the ground is worked under a service agreement in every one, arranged directly with the operating company.

From a procurement file
The promise, the water, the precedent and the exit
Is this a dust suppression service?
No. A subscription is written against the toxic fraction of the ground inside a defined service zone, sterilizing what sits in playa, dust, soil and exposed ground so it does not travel with whatever eventually lifts.
Treated ground tends to hold together better for a while, and clients who have walked a treated area bring it up. The effect is short-lived and no part of the contract. No reduction percentage, area figure or water-per-area ratio is contracted, published or priced.
If dust movement is the whole of your obligation, say so in the first email. The desk assessment will say whether this is the wrong instrument.
Where does the water come from?
Usually from whatever the site already uses for ground work, metered from day one. Water is the binding constraint on anything applied to a surface in an arid region, so every liter is accounted for.
The meter answers a cost question and a stewardship question, both asked wherever dust control competes with irrigation. The service is not sold on a water ratio.
Can this be procured against an existing dust obligation?
Usually, with one thing in writing at the start: a detox duty runs alongside control measures a regulator has approved and never in place of them, so nothing already accepted comes off a site.
The comparison runs on a monitoring network your authority already operates, and the sampling record is new information nobody previously held.
What happens if the control area shows no benefit?
The program stops. The no-benefit endpoints are named in the protocol before anything is mobilized.
You keep the baseline, the laboratory record and the monitoring record. On a surface never characterized in depth, that has value whether or not a program follows.
The contract, the price and the mobilization date all belong to Alarivean, Inc. Sophia Delta owns the system and signs nothing.
