On a very regular basis I receive requests now from ChemSpider users for what I would call “General Help”. Here’s a request from a user to answer a Chemistry Question. Can the community help?
“We have detected 2,2 Dichloropropionic Acid in several of our drinking water systems at levels of about 0.1 to 0.2 ug/L (above the EU MCL), but none in the source water (in some cases surface water, in others, groundwater under the direct influence of surface water). The levels in the pipe rise after the addition of free chlorine. This leads me to believe that either some sort of lab interference or some other compound is actually being detected. We have sent samples to two separate labs using two different methods (blanks were not sent) and the results were confirmed.
Any thoughts on how 2,2 Dichloropropionic Acid might be naturally formed in the presence of chlorine in drinking water? Is it possible that other organics either degrade down to 2,2 Dichloropropionic Acid or are precursors for 2,2 Dichloropropionic Acid, in the presence of chlorine?”
Please post your comments on this blog and I will ask the user to watch this page.
This is part of our future endeavors. Shortly we will establish a discussion forum for ChemSpider users so that when a user has scientific problems you can post here and discuss. Should the outcome from the discussion be science associated with a particular chemical we will add it to a record n the database for further reference.Stumble it!
