01 · What we test

Six panels. The full pesticide spectrum.

Pesticide chemistry covers a hundred classes with mutually exclusive instrument requirements. We split the work the way the methods do — multi-residue LC-MS/MS for the modern 60+ analyte core, separate GC-MS for the legacy organochlorines, and dedicated LC-MS/MS for glyphosate.

01
EPA-aligned multi-residue

Multi-residue 60-analyte (LC-MS/MS)

60+ analyte LC-MS/MS pesticide screen covering organophosphates, carbamates, neonicotinoids, pyrethroids, triazoles, and triazines. The modern reference panel for produce, soil, and irrigation water — extracts in QuEChERS or solvent depending on matrix.

LOD 0.5–10 ppb · 5–7 days
02
LC-MS/MS dedicated

Glyphosate + AMPA

Glyphosate and AMPA (its primary degradation product) by dedicated LC-MS/MS with derivatization. Won't multiplex into the multi-residue panel because of polar / non-volatile chemistry — runs as a separate workflow.

LOD 5 ppb · 5–6 days
03
GC-ECD / GC-MS

Organochlorines (EPA 8081)

Legacy organochlorine pesticides — DDT (and DDD/DDE metabolites), aldrin, dieldrin, endrin, heptachlor, lindane, methoxychlor, chlordane. Mostly banned but persistent in soil and sediment for decades; still required for site characterization.

LOD 0.1–1 ppb · 5–7 days
04
GC-FPD / LC-MS/MS

Organophosphates (EPA 8141)

Standalone organophosphate panel — chlorpyrifos, malathion, diazinon, parathion, methyl-parathion. Used when the multi-residue panel needs a confirmation by orthogonal method or for higher-sensitivity OP-specific characterization.

LOD 1 ppb · 5–7 days
05
LC-MS/MS

Carbamates (EPA 8321)

Carbamate insecticides and herbicides — carbaryl, methomyl, aldicarb, oxamyl, propoxur. Thermally labile; LC-MS/MS rather than GC for accurate quantitation.

LOD 1 ppb · 5–7 days
06
LC-MS/MS targeted

Tank-mix residue confirmation

Targeted re-analysis of a flagged residue or known tank-mix combination. Used when a multi-residue hit needs higher-confidence quantitation, or when an applicator wants to verify carryover from a previous tank load.

03 · Common pesticide failure modes

Where pesticide residues turn up in the audit.

Glyphosate in oats, atrazine in surface water, organochlorines in old orchards. Each crop and water type concentrates a different residue class — the right scope catches the right one.

Glyphosate (oats / lentils / wheat)
LC-MS/MS · ppb · grain / legume
High risk
Pre-harvest desiccant residue — used to hasten dry-down. EWG / class-action complaints concentrate here. EPA tolerances vary by commodity (15–40 ppm for many grains).
Atrazine (surface / drinking water)
LC-MS/MS · µg/L · water
High risk
Most-applied US herbicide on corn. Federal MCL 3 µg/L drinking water; surface-water concentrations often spike post-application in spring runoff.
Chlorpyrifos (OP, banned)
GC-MS / LC-MS/MS · ppb
High risk
Banned for food-use applications in 2022 but persistent in soil. Recurring detection in legacy agricultural sites and imported produce — re-tolerance proposed in some commodities.
Imidacloprid + neonics
LC-MS/MS · ppb · soil / water / honey
High risk
Pollinator-toxicity driver. Common neonic formulations (imidacloprid, clothianidin, thiamethoxam) persist in soil for years; tracked in surface water near treated row-crop areas.
DDT / DDE / DDD (legacy OC)
EPA 8081 · ppb · soil / sediment
Medium risk
Banned 1972 but environmentally persistent. Still appearing in agricultural soils 50 years later. DDE (degradation product) often dominates the profile.
Pyrethroids (bifenthrin, permethrin)
LC-MS/MS · ppb · soil / runoff
High risk
Modern replacement for OC and OP insecticides. Strongly soil-binding; concentrate in stormwater sediment downstream of urban / agricultural runoff. Fish-toxicity action driver.
04 · Compliance

EPA, FDA, USDA — the limits we report against.

Pesticide regulation crosses EPA (water + applications), FDA (food residues), and USDA (commodity tolerances). Every COA reports observed value vs the published limit your reviewer cites.

40 CFR Part 180
EPA pesticide tolerances on food

Commodity-specific pesticide tolerances codified in 40 CFR Part 180. Our 60-analyte panel covers the most-cited residues with retest pricing for any out-of-tolerance hits.

EPA 525 / 1694
Drinking-water & wastewater pesticide methods

EPA 525.3 (LC-MS/MS for finished drinking water) and EPA 1694 (LC-MS/MS for wastewater) define the published reference methods for pesticide residues in water matrices.

EPA 8081 / 8141 / 8321
SW-846 pesticide methods

EPA SW-846 hazardous-waste pesticide methods: 8081 (organochlorines, GC-ECD), 8141 (organophosphates, GC-FPD), 8321 (carbamates, LC-MS/MS). The reference methods for soil / sediment Phase II ESA work.

EPA Federal MCL
Drinking-water Maximum Contaminant Levels

Federal MCLs for pesticides in finished drinking water — atrazine 3 µg/L, glyphosate 700 µg/L, alachlor 2 µg/L, simazine 4 µg/L, lindane 0.2 µg/L. We report against the MCL on every drinking-water pesticide COA.

USDA PDP
Pesticide Data Program

USDA Pesticide Data Program annual sampling targets common-commodity tolerances and exceedance trends. Our panels mirror the PDP analyte list to support importer / retailer commodity audits.

No — glyphosate has polar, zwitterionic, non-volatile chemistry that won't multiplex into the standard multi-residue method. We run it as a dedicated LC-MS/MS workflow with derivatization for $109 standalone or $269 bundled with the multi-residue panel. Most grain / legume / oat audits need both.
