Administration of Air and Water Resource and Solid Waste Management Programs (NAICS 92411)

A Histometrics industry primer for public- and private-market investors

Short primer — single-child pass-through. This page covers NAICS (North American Industry Classification System) industry 92411, a five-digit level that contains exactly one national industry, 924110, with the same name. The two are effectively identical. This page gives the level's own figures and the essentials; for the full treatment — investable-universe tables, how the money works, regulation, and the outlook — see the 924110 primer.

1. Overview

This is not a company sector — it is the government itself. NAICS 92411 covers the federal, state, local, and tribal agencies that write, permit, monitor, and enforce the rules on clean air, clean water, and waste: the U.S. Environmental Protection Agency (EPA); the 50 state environmental departments (often a DEP or DEQ — Department of Environmental Protection or Environmental Quality); regional air-quality districts; and local solid-waste, drainage, and flood-control authorities.[1]

Why an investor cares: these agencies are the demand engine and rule-writer for a large private economy — trash and hazardous-waste companies, water utilities, water-treatment technology firms, and environmental engineers. A permit deadline, a new limit on a chemical, or a wave of federal grant money can move billions of dollars of private spending. You cannot buy stock in the EPA. You invest around this industry, not in it: through the private companies it regulates, funds, and hires, and through the municipal bonds that finance the water and sewer projects it mandates.[1]

2. What's inside — and why the level equals its one child

NAICS builds from broad to narrow: sector (2-digit) → subsector (3) → industry group (4) → industry (5) → national industry (6). At the five-digit level, 92411 has a single six-digit child, 924110, that carries the identical definition. There is nothing in 92411 that is not in 924110 — no second bucket to weigh against it, no aggregation choices to make. The rollup is the child.

That single child covers government offices that administer, regulate, and enforce programs for air and water resources; solid-waste management; air and water pollution control and prevention; flood control; drainage and water-resource use; and toxic-waste removal and cleanup.[1] The key word is administration — this code is the regulator and the check-writer, not the truck, the pipe, or the landfill. Private waste haulers (NAICS 562), water and sewer utilities (221310, 221320), and environmental consultants (541620) sit in their own codes, not here.[1] Ownership at this level is essentially 100% government.

Because the level collapses to one child, everything below is a summary. For the detailed build-out, read the 924110 primer.

3. How big it is (this level's figures)

Our ingested ground-truth dataset holds no official metrics for NAICS 92411 — no revenue, employment, establishment, or payroll figure here comes from that source, and none is invented. That absence is expected and informative. Because this is a Public Administration industry (NAICS sector 92), the standard "how big is this business" datasets miss it by design: the Census Bureau excludes government establishments from County Business Patterns (CBP) and the Statistics of U.S. Businesses (SUSB), so those series show almost nothing for a government function.[3] Any commercial business-list count for the code (a few thousand "employees") is a rounding error against reality and should be treated as an undercount.[3]

Since 92411 equals 924110, the level's true scale is the child's scale. The right yardstick is the Bureau of Labor Statistics' Quarterly Census of Employment and Wages (QCEW), which does count government payrolls. Treat the figures below as a cited external estimate, not our ingested ground truth:

BLS QCEW, 2024 annual averages, NAICS 924110 = 92411 (government):[4]

Total payroll ran roughly $12.2 billion in 2024, split by employment about 49% local, 36% state, 15% federal.[4] The federal-budget anchor at the top of the system is EPA's regular annual appropriation of about $8.8 billion for fiscal 2026 (roughly $20.8 billion counting Infrastructure Investment and Jobs Act advance appropriations); state environmental-agency budgets averaged $486.7 million in fiscal 2023, a jump driven mostly by federal money passing through to the states.[5][6]

Undercount caveat: federal business statistics understate this level because government establishments are excluded from the small-business series; QCEW is the credible count, and it, too, tallies public payrolls rather than the far larger private spending these agencies set in motion.[3][4]

4. Investable universe — where the value sits

There is no direct equity in 92411; you cannot own a share of a regulatory agency. Value concentrates entirely in the served private markets its one child regulates and funds — an oligopoly of listed waste operators (WM, Republic Services, Waste Connections, GFL Environmental), hazardous-waste and remediation firms (Clean Harbors), regulated water utilities (American Water Works), water-technology suppliers (Xylem, Veralto, Pentair), environmental-engineering firms (Tetra Tech, Jacobs, AECOM, Stantec, WSP), and private-equity-backed platforms (Reworld, Apex, Coastal, Noble). Income investors reach the actual projects through the municipal-bond market (water and sewer revenue bonds). Company-by-company tickers, revenue, and market-cap detail live in the 924110 primer, Section 4 — not repeated here.

5. How the money works

These agencies do not earn profit; they run on appropriations, taxes, permit and user fees, fines, grants, and low-interest loans, and their spending becomes revenue for the private ecosystem.[5][6] The flywheel is the State Revolving Funds (SRFs) — federal money that capitalizes state loan programs, which then fund local water and sewer projects and convert agency budgets into contracts for utilities, engineers, and builders.[9][11] Enforcement adds more: EPA drove over $1.17 billion in commitments from responsible parties in fiscal 2024, and Superfund manages roughly 1,340 National Priorities List sites that feed remediation contractors.[12][13] The administration function itself is defensive (permitting and public-health duties do not vanish in a recession); the private operators exposed to it are more cyclical. Full mechanics — and the per-business-model metrics (route density, rate base, backlog, book-to-bill) — are in the 924110 primer, Section 5.

6. Demand drivers

The same forces that drive 924110 drive this level, because they are the same industry:[7][8][9][14][15]

• New and tightening rules — limits on PFAS (per- and polyfluoroalkyl substances, the "forever chemicals"), mandatory lead service-line replacement, and air standards each mandate private spending.
• Federal funding cycles — IIJA water money and SRF drawdowns set the pace of local projects.
• Aging infrastructure, population, and climate — old pipes, landfill limits, drought, and flooding create work regardless of politics.
• Enforcement intensity and the political administration — the single biggest swing factor, and it flips with elections.

7. Regulation

This industry is the regulation, organized under "cooperative federalism." Federal statutes set national floors — the Clean Air Act (CAA), Clean Water Act (CWA, including National Pollutant Discharge Elimination System / NPDES permits), Safe Drinking Water Act (SDWA), Resource Conservation and Recovery Act (RCRA), and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA / "Superfund").[15][15] EPA writes the national standards; states that adopt rules at least as strict receive "primacy" — delegated authority to run permitting, inspections, and enforcement — which is why the state and local layers employ far more people than the federal one (Section 3).[14] Statute-by-statute detail is in the 924110 primer, Section 7.

8. Consolidation

There is no market-share competition inside a government function, so the consolidation story is identical to the child's and plays out in the served markets: a solid-waste oligopoly (WM, Republic Services, Waste Connections, GFL) and accelerating private-equity roll-ups in regional trash hauling and water/wastewater operations. Recent deals — WM's ~$7.2 billion purchase of Stericycle, Republic's ~$2.2 billion purchase of US Ecology, Xylem's ~$7.5 billion acquisition of Evoqua — leave the same agencies facing fewer, larger private counterparties. The parallel dynamic within government is the devolution tug-of-war: authority and money shifting between EPA and the states with each administration.[5]

9. Risks

• Political and budget whiplash. EPA's workforce is being cut sharply (roughly a fifth to nearly a third over 2025–2026), which slows permits, rulemaking, and enforcement.
• Regulatory reversal and litigation. Rules can be written, litigated, rolled back, and rewritten; EPA has proposed rescinding certain PFAS provisions while leaving the PFOA/PFOS numeric limits unaffected (proposal not yet final).[15]
• Funding cliffs. IIJA and SRF money tapers, and local project pipelines can shrink when it ends.[9][11]
• Unfunded mandates on states. Delegated authority without matching money strains state agencies.
• Indirect exposure for investors. Deregulation shrinks mandated spend; tightening (PFAS, lead) creates it — the bet is on the direction of regulation as much as on any single company. Operating and market risks for the served firms are covered in the 924110 primer, Section 9.

10. How to invest, and the outlook

You cannot buy the industry — it is government. The routes in are the same as for 924110: public markets (the waste oligopoly, hazardous-waste and remediation firms, environmental-engineering firms, water-technology suppliers, regulated water utilities, and SRF-backed municipal bonds) and private markets (private-equity and infrastructure funds, direct company equity or debt, municipal and green bonds, and public-private partnerships). Reserve share-price, dividend-yield, and valuation-multiple work for the individual names — see the 924110 primer, Section 10.

Near-term outlook. Two forces pull opposite ways. For private demand: mandates already on the books — PFAS treatment, lead-pipe replacement — plus aging infrastructure and still-deploying IIJA dollars keep spending growing regardless of Washington's mood.[7][8][9][14][15] Against it: a deregulatory federal posture and a shrinking, lower-budget EPA slow new rulemaking and enforcement and push the burden onto cash-strapped states.[5] The likely shape: the agencies themselves contract even as the private markets they created keep growing. Track the regulatory direction, the federal grant cycle, and state-agency capacity as the leading indicators.
