Abstract: This EPA treatment technology project was designed to collect data on the performance of existing water treatment processes in order to remove arsenic on pilot-scale. Our paper contains verification testing of the reverse osmosis membrane module conducted over a 30-day period at the Spiro Tunnel Bulkhead water (Park City, Utah, USA), which is considered to be a ground water. The total arsenic concentration in the feed water averaged 60 ppb during the test period and was reduced to an average of 1 ppb in the treated (permeate) water. The work reported here focused on obtaining accurate readings for arsenic valence states (III) and (V), using an anion exchange resin column. The dominant arsenic species in the abandoned silver mine tunnel feed water was As(V). Results of analysis showed that 70% of the arsenic present in the feed water was in dissolved form. Arsenic speciation for valence states (III) and (V) showed that arsenic (V) represented 76% of the dissolved arsenic in the source water. The method detection limit (MDL) for arsenic using ICP-MS was determined to be 0.1 ppb. Our matrix spiked recovery, spiked blank samples and reference materials deviated only a few percentage points from the listed true values.

Course Description GROUNDWATER PRODUCTION CEU TRAINING COURSE This short CEU training course is a detailed explanation of Water Distribution and Water Treatment Methods and related water fundamentals along with detailed understanding pumps and motors. This is an excellent course that applies to both Water Treatment and Distribution Operators. This course also covers in detail: Disinfection, Chlorine, O3 and disinfection alternatives, and related byproduct fundamentals. Water Quality, Tastes and Odor Problems and MCL/EPA Rules and a basic understanding of how the rules were created and implemented will be covered. This course will also cover advanced groundwater production and protection with distribution problem solving solutions.

DISTRIBUTION BASICS CEU TRAINING COURSE Second Edition Review of water distribution systems and related treatment fundamentals. This course will cover the basic requirements of the Safe Drinking Water Act and general water distribution principles. You will not need any other materials for this course. Water Distribution, Well Drillers, Pump Installers, and Water Treatment Operators. The target audience for this course is the person interested in working in a water treatment or distribution facility and/or wishing to maintain CEUs for certification license or to learn how to do the job safely and effectively, and/or meet education needs for promotion. Final Examination for Credit The opportunity to pass the final comprehensive examination is limited to three attempts per course enrollment.
