Municipal water typically maintains pH between <strong>6.5 and 8.5<\/strong>. Low pH indicates corrosive water that can dissolve metals from pipes; high pH may cause scale formation and affect disinfection effectiveness.<\/p>\n<p><strong>Chlorine residual<\/strong> quantifies remaining disinfectant concentration after treatment and distribution. EPA regulations require minimum free chlorine of <strong>0.2 mg\/L<\/strong> throughout the distribution system to prevent microbial regrowth.<\/p>\n<p><strong>Turbidity<\/strong> measures water clarity by detecting light scattering from suspended particles. Turbidity serves as both an aesthetic indicator and a surrogate for microbial risk\u2014elevated turbidity often precedes contamination events.<\/p>\n<p><strong>Conductivity<\/strong> indicates total dissolved ion concentration, providing information about water mineral content. Sudden conductivity changes may signal infiltration, cross-connections, or treatment failures.<\/p>\n<p><strong>Dissolved oxygen (DO)<\/strong> measures oxygen concentration in water.
