## Safety and limitations

The site supports preliminary planning. Outputs are not formal engineering approval, sampling authorization, potable-water certification, legal advice, manufacturer selection, or a universal regulatory determination. Verify measurements, accredited laboratory results, applicable requirements, official certified-product listings and current manufacturer data. Chemical dose and CT tools use user-supplied targets and never recommend legal or health values. Greywater tools never approve a source, potable use, plumbing connection, storage method, setback or jurisdictional compliance. Vehicle-wash tools never select treatment, approve reclaimed-water quality, or authorize wastewater, reject, backwash or sludge discharge. Metal-finishing tools never set chemistry, rinse acceptance, exposure or discharge limits. Monitoring-well tools never select a sampling method, establish representativeness, authorize sample collection or approve purge-water disposal.
