We are pleased to present a summary
of the quality of the water provided to you during the past year as a part of the 1996 Safe Drinking Water Act (SDWA) requirements that
water utilities issue an annual "Consumer Confidence" report to customers. This
report is based upon tests conducted by the City of Pocatello Water Department.
