Section 179-13-003 - GENERAL REQUIREMENTS003.01 Each public water system with a surface water source or a ground water source under the direct influence of surface water must provide treatment of that source water that complies with these treatment technique requirements. The treatment technique requirements consist of installing and properly operating water treatment processes which reliably achieve: The treatment technique requirements consist of installing and properly operating water treatment processes which reliably achieve: 1. At least 99.9% (3-log) removal and/or inactivation of Giardia lamblia cysts between a point where the raw water is not subject to recontamination by surface water runoff and a point downstream before or at the first customer, and2. At least 99.99% (4-log) removal and/or inactivation of viruses between a point where the raw water is not subject to recontamination by surface water runoff and a point downstream before or at the first customer.003.02 Each ground water source providing water to a public system will be examined to determine whether or not it is under the direct influence of surface water. The examination will be performed in accordance with the protocol described in Attachment 2 to 179 NAC 13. 13-003.02A Each ground water source for a community water system must have been examined no later than June 19, 1994.13-003.02B Each ground water source for a non-community system must have been examined by June 19, 1999.13-003.02C If the Director determines that a ground water source is under the direct influence of surface water, s/he will so indicate in writing to the owner of the public water system.003.03 A public water system using surface water as a source must include filtration which meets the requirements of 179 NAC 13-006.003.04 A public water system using a ground water source under the direct influence of surface water is considered to be in compliance with the requirements of 179 NAC 13-003 if: 1.
