This slide presentation outlines perchlorate resins and nitrosamine byproducts. Topics outlined include: ion exchange for perchlorate removal;
nitrosamines and drinking water;
bench and pilot testing of nitrosamine
leaching; and,
regulation and risk balancing. A case study on ion exchange for perchlorate removal is outlined: California Domestic Water Company, pilot tests of "perchlorate-selective" resins identified
several contenders that will drastically reduce resin
quantities needed and water treatment costs; and, bench and pilot testing of nitrosamine leaching. Summary and conclusions were:
use of anion exchange resins in water
treatment to remove perchlorate may introduce
nitrosamines into the water;
improved resin rinsing strategies and potential
for nitrosamine destruction by UV treatment
should be examined to reduce risk; and,
additional research needed to assess the "cost
of lunch" and weigh the relative risks imparted
by water treatment processes. Includes table, figures.
