Nikwax TX.Direct Wash-In 300ml: approximately £8-£11 UK retail (Cotswold Outdoor, Blacks, Mountain Warehouse). Coverage: up to 3 garments per 300ml bottle. At £3.33 per garment per application x 3-7 reapplications per year = £10-£23 per garment per year. Arithmetic rounded to £10-£25 range.
Externality arithmetic inputs: PFAS mass per legging approximately 10-20 mg PFAS-equivalent (32 ppm organic F in approximately 200g fabric, stoichiometric conversion at conservative midpoint); textile-origin allocation to drinking-water loading assumed at 1-5% (no peer-reviewed disaggregation of textile-use-phase PFAS contribution to drinking-water loading from industrial, AFFF, and biosolid sources has been published as of April 2026 -- see EPA NPDWR 2024 Regulatory Impact Analysis, $1.63B/yr compliance cost across all sources); GAC treatment cost EUR 0.02-0.10 per cubic metre (Belkouteb N et al. (2020), Water Research 182:115913, DOI: 10.1016/j.watres.2020.115913, Uppsala full-scale plant); discount rates per HM Treasury Green Book declining schedule (3.5%/3.0%/2.5%) and Stern Review (0.1%). Present-value calculation for year 2200 (174 years): at Green Book declining rates, compound discount factor = (1/1.03530) x (1/1.0345) x (1/1.02599) = approximately 0.008, i.e. ~0.8p per pound; at Stern 0.1%, (1/1.001174) = approximately 0.84, i.e. ~84p per pound. Ratio: approximately 100-fold.

This report was produced by YAN Consumer Intelligence using AI analytical systems that cross-reference regulatory frameworks, scientific evidence, and publicly observable product information to identify information gaps. Where organisations or products are referenced, they appear as representative examples of systemic patterns -- not as subjects of allegation. Our analysis examines what standards and regulations require, not whether any individual organisation has acted wrongfully. Organisations referenced in this report are invited to provide additional context or corrections at [email protected].
