In India, where should I get tested the organic micropollutants such as preservatives (methylparaben, ethyl paraben), plasticizers (Bisphenol-A), surfactants (Nonylphenol), fragrances (Galaxolide, Tonalide, Caffeine), UV filters (Octocrylene, 4MBC, EHMC, BP3) in a greywater sample (liquid)? I am ready to pay the testing charges
