Berkey Phoenix Pesticide and Pharmaceutical Test Results
Two of the categories people ask about most and see documented least: agricultural chemicals and prescription drugs. This report screened both in one pass, plus semi-volatile organics and PCBs, using spiked water and instrumental analysis.
Lab: RAYNU Analytical and Research Lab LLP, Bangalore, ISO/IEC 17025:2017 accredited. Report 2510041B, test window 2-27 September 2025, following NSF/ANSI 401 protocols alongside APHA 22nd edition, AOAC 20th edition and EPA guidance.
Each compound was spiked to a known concentration, most at 1,000 µg/L, and measured after filtration with a 1 µg/L reporting limit.
More than fifty pesticides and herbicides were screened, including organochlorines such as DDT and its breakdown products, triazines such as atrazine, and phenoxy herbicides such as 2,4-D and 2,4,5-TP. Reported reductions were 99.9% or above, with most rows reading below the reporting limit after filtration.
| Pesticide / herbicide | Influent (µg/L) | Effluent (µg/L) | Removal |
|---|---|---|---|
| 2,4-D | 1000.0 | < 1 | 99.9%+ |
| 2,4,5-TP | 1000.0 | < 1 | 99.9%+ |
| 4,4-DDD | 1000.0 | < 1 | 99.9%+ |
| Alachlor | 1000.0 | < 1 | 99.9%+ |
| Aldrin | 1000.0 | < 1 | 99.9%+ |
| Chlordane | 1000.0 | < 1 | 99.9%+ |
| Dieldrin | 1000.0 | < 1 | 99.9%+ |
| Endosulfan Sulfate | 1000.0 | < 1 | 99.9%+ |
| Glyphosate | 1000.0 | < 1 | 99.9%+ |
| Heptachlor | 1000.0 | < 1 | 99.9%+ |
Report 2510041B itemises these ten compounds at 1,000 µg/L each. Its remaining forty-plus pesticide rows are summarised in the report at 99.9%+ rather than printed individually, so we have not invented per-compound figures for them. This page shows exactly what the document shows.
Thirteen pharmaceutical compounds were tested at 1,000 µg/L each, spanning antibiotics, hormones, an anticonvulsant and common over-the-counter analgesics. Every row returned below the 1 µg/L reporting limit.
| Pharmaceutical | Influent (µg/L) | Effluent (µg/L) | Removal |
|---|---|---|---|
| Acetaminophen (Tylenol) | 1000 | < 1 | 99.9%+ |
| Atenolol (Beta blocker) | 1000 | < 1 | 99.9%+ |
| Carbamazepine (Epilepsy drug) | 1000 | < 1 | 99.9%+ |
| Ciprofloxacin HCl (Antibiotic) | 1000 | < 1 | 99.9%+ |
| Diclofenac Sodium (NSAID) | 1000 | < 1 | 99.9%+ |
| Erythromycin USP (Antibiotic) | 1000 | < 1 | 99.9%+ |
| Estrone (Hormone) | 1000 | < 1 | 99.9%+ |
| Ibuprofen (Advil/Motrin) | 1000 | < 1 | 99.9%+ |
| Phenytoin (Epilepsy drug) | 1000 | < 1 | 99.9%+ |
| Progesterone (Hormone) | 1000 | < 1 | 99.9%+ |
| Sulfamethoxazole (Antibiotic) | 1000 | < 1 | 99.9%+ |
| Triclosan (Antimicrobial) | 1000 | < 1 | 99.9%+ |
| Trimethoprim (Antibiotic) | 1000 | < 1 | 99.9%+ |
Thirty-plus semi-volatile organic compounds were screened, including polycyclic aromatic hydrocarbons and phthalates, plus eight polychlorinated biphenyls. Reported reductions were 99.9% or above. The published tables summarise these groups in aggregate rather than printing every compound, so no per-compound rows are claimed here. PCBs are legacy industrial contaminants, banned for decades, that persist in sediment and older plumbing systems.
