Assistance Type: OTHER WATER QUALITY - Response to chlorine supply shortage
Reasons: Chlorine
 
Details: Rob summarized completed chlorine supply survey, in response to potential shortages regionally.
CRW has at least 30 days of sodium hypochlorite supply, as of 6/17. To conserve, they have ceased serving all of CRW - Clairmont, or the South system, with South Fork WB serving the entire South system, as they have plenty of on-site generated chlorine. Also today, CRW ceased pre-chlorinating, and is only chlorinating after filtration for entire 1.0-log giardia inactivation. They have increased volume and chlorine residual levels in clearwell as a result, but are meeting CT requirements.
