Reachable Buyer Map

Prepared for Charl du Preez · Eurofins Environment Testing · September 2026
Here is the map Ben promised. Eurofins Environment Testing lists its work as air and vapor, built environment, ground and surface water, industrial hygiene, municipal and drinking water, PFAS, and soil and hazardous waste testing, among other services, for clients in both the public and private sectors. So this page maps the US organizations that commission that kind of testing: which groups they fall into, who inside each one decides which lab gets the work, and roughly how many exist. It maps the market around Eurofins, not Eurofins itself, and there is nothing to buy at the end of it.
Where the lab decision actually sits
Seven rows, from the firms that send samples on behalf of someone else, to the organizations that sample for their own permits, to the edge of the market. Counts are banded on purpose and count locations or permitted systems, not companies or people. A firm with several offices appears once per office.
Environmental consulting firms
Firms that run site investigations, due diligence, monitoring programs and compliance work for property owners, industry and public agencies. Most of the samples they collect go to an outside lab, and the firm usually picks which one.
Who holds it: the project manager on each job picks the lab day to day. A principal or program manager sets the preferred lab list for the office, and a chemistry or data quality lead checks methods, accreditation and turnaround before a new lab is added.
About 9,700
US environmental consulting locations. About 1,000 of them have 20 or more staff.
Remediation contractors
Contractors that carry out the cleanup once a site is characterized. Confirmation sampling decides when a phase is finished, so the lab result sits directly on their schedule.
Who holds it: the project or site manager on each cleanup, with the operations lead or the company's environmental compliance manager setting which labs are approved.
About 5,800
US remediation services locations. About 1,000 of them have 20 or more staff.
Larger drinking water utilities
Community water systems serving more than 10,000 people. They sample on a fixed compliance calendar, and many run an in-house lab for routine work while sending specialty analyses to a contract lab.
Who holds it: the water quality manager or laboratory supervisor, with the compliance manager and the utility director signing off. Public utilities often buy lab services through a formal bid.
About 4,600
active community water systems serving more than 10,000 people. Roughly 490 serve more than 100,000.
Smaller community water systems
Systems serving 10,000 people or fewer. This is most of the country's water systems by number, and many are too small to run a lab of their own.
Who holds it: the system operator or public works director, and at the smallest systems a town manager or owner. Many are reached through their state's rural water association or their engineering consultant rather than one at a time.
About 44,800
active community water systems serving 10,000 people or fewer. About 26,500 serve 500 people or fewer.
Municipal wastewater treatment plants
Publicly owned treatment works whose discharge permit is classed as major. Effluent monitoring is written into the permit, and pretreatment programs add sampling of the industrial users that discharge to the plant.
Who holds it: the plant superintendent and the laboratory supervisor, with the pretreatment coordinator owning the industrial user side. Larger authorities buy through procurement.
About 4,200
publicly owned treatment works with a current discharge permit classed as major by federal regulators.
Industrial facilities with a major discharge permit
Plants discharging directly to a river, lake or coastal water under their own permit, classed as major. Their monitoring runs on the permit's schedule whether or not a consultant is involved.
Who holds it: the environmental manager or EHS manager at the plant, with the plant manager and, in a larger company, a corporate environmental director setting lab standards across sites.
About 2,300
non-municipal facilities with a current discharge permit classed as major by federal regulators.
Building owners and facility managers
The buyers behind built environment and industrial hygiene testing: school districts, property managers, hospitals, and employers checking air, water and materials inside their own buildings. No federal registry lists them as a group. Rather than show a number built on a guess, this row carries none.
Who holds it: the facilities director or EHS manager, often through an industrial hygiene consultant who collects the samples.
No public count
not carried by the registries this page uses, so this segment is built by name rather than counted.

Where the openings are

1
The consulting firm is the buyer that multiplies. One project manager at a consulting firm sends samples from many sites and many clients. About 1,000 consulting locations with 20 or more staff is a list small enough to work in full, by name, starting with the people who set the preferred lab list for each office.
2
Utilities and permit holders buy on their own calendar. About 4,600 larger water utilities, 4,200 treatment plants and 2,300 industrial permit holders sample on schedules set by regulation and by their permits. The lab decision sits with a named person at each one, which makes these rows a separate list from the consulting firms, not a subset of it.
3
The service list is wider than any one buyer sees. A utility that knows you for drinking water may not know you for PFAS or microplastics, and a consulting office that sends soil may not know you run air and vapor. Each row above can be approached with the one service that matters to that buyer, rather than the whole catalog at once.
Built from public federal business and environmental registries, current to September 2026. Counts are banded deliberately and count locations or permitted systems, not companies. A segment with no credible public number says so rather than showing one.
