I'd be cautious about assuming every job has MIC and spending (my) money on every job to cure it; perhaps contractually saddle the spkr guy with the testing and specify a couple labs and/or procedure. Make it an allowance if you need to, since most of us aren't going to want to test the water before bid day, heck its hard enough to find out what flow info is available.

My second foray into water quality testing is about all the farther I want to go into this subject. Here's what I have learned: 1. This is an owner requirement but owners don't know they have this responsibility. 2. There may be one handful of labs in the country who are able to do the testing. 3. There is no standard protocol for performing the testing. 4. Ed Schultz made 3 attempts to make positive changes to NFPA 13 (ROP 469, 470, 471) but he got 3 rejections for the '10 edition. However, the committee did add two additional owner options just in case some owner out there stumbles onto this requirement. 5. There's no obligation for the engineer, designer, or contractor to be involved in this subject whatsoever. If not notified by "the owner", then all the rest of us who understand the problem and its consequences can say "the owner" did not inform us. 6. It's pretty clear the committee wants to keep it this way. I'm planning to specify a system treatment approach for every job. Right now I'm leaning toward the Potter approach with the portable chemical injection system. What are the pros and cons of this approach? Bill Brooks William N. Brooks, P.E.
