01Drinking Water Treatment and Distribution
The Drinking Water Treatment and Distribution domain tests whether you can trace a gallon of water from source to tap and prove each barrier worked.

Wastewater Treatment and Collection tests process control and collection-system stewardship: influent characterization, secondary treatment, disinfection, solids handling, and the sanitary sewer's capacity to keep sewage out of basements and waterbodies. Primary treatment removes settleable solids; secondary biological treatment (activated sludge, trickling filters, RBCs, lagoons) removes BOD and TSS.

Water Quality Analysis, Sampling, and Reporting covers the defensibility of data: sample siting, collection, preservation, holding time, chain of custody, laboratory QA/QC, and reporting to NHDES and the public. Bacteriological samples under the Revised Total Coliform Rule follow a written sample siting plan; routine samples are collected at designated sites, and a positive total coliform triggers repeat samples and, at a threshold, an assessment.
