The City of Houston Northeast Water Purification Plant (NEWPP) Section Chief was contacted and informed us that the manganese level was higher than normal over the weekend, and treatment had been modified to neutralize the effects (including discoloration of the water). The Authority is currently receiving clear water from the NEWPP, and as the discolored water still in the system works its way through the system, the water received by the districts will regain its normal high quality. Manganese is covered in the EPA’s Secondary Drinking Water Standards as a chemical that may affect the aesthetics of the water for some customers when the SMCL is exceeded but does not pose a risk to human health.
