Comments on Highly Sensitive & Low Cost Colorimetric Method for Quantifying Arsenic Metal in Drinking Water of Malwa Punjab and Comparison with ICAP-AES, has been presented. There is no validation of this new developed method using recovery/standard addition method, optimization of variables pH, reagent concentration, λ max, nor any study of effect of foreign ions/tolerance limits and its comparison with EPA-standard method reported in the literature, instrument manufacturer/models, etc. Moreover, the procedure described in the manuscript is practically impossible. There is no update of literature survey on arsenic determination in water. The authors claims are selfcontradictory, highly misleading and has no scientific basis.
