Details:	SUMMARY: Inspected chlorination system DETAILS: Visited system to inspect modifications to the existing chlorination system. Sodium hypochlorite is now injected into the well discharge line (rather than the well itself), and two new 120 gallon tanks provide disinfection contact time, along with the existing 60 gallon pressure tank. Based on 30gpm reported well yield, I advised operator to maintain 0.7 ppm chlorine residual in the system. (Contact time =260 gal/30gpm = approx 9 min).Required CT = 6, so Cl residual of 0.7 producing a CT of 0.56 should be sufficient, especially considering the sporadic water use. ACTION NEEDED: Wrote approval letter. Also sent info on emergency response plans.
