Section Env-Ws 342.10 - Treatment Techniques(a) The department shall require community water systems and non-transient, non-community water systems to install and use any treatment method identified in Env-Ws 345 through Env-Ws 347 as a condition for granting a variance except as provided in (b), below. If after the installation of the treatment method the system still cannot meet the MCL, the system shall be eligible for a variance.(b) If a system can demonstrate, through comprehensive engineering assessments which may include pilot plant studies, that the treatment methods identified in Env-Ws 345 through Env-Ws 347 would only achieve a de minimis reduction in contaminants, the department shall issue a schedule of compliance that requires the system being granted the variance to examine other treatment methods as a condition of obtaining the variance.(c) If the department determines that a treatment method identified in (b), above, is technically feasible, the department shall require the system to install and use that treatment method in connection with a compliance schedule issued. The department's determination shall be based upon studies by the system and other relevant information.(d) The department shall require a public water system to use bottled water or point-of-use devices or other means as a condition for granting a variance from the requirements of Env-Ws 345 through Env-Ws 347 to avoid an unreasonable risk to health.N.H.
