The well owner is responsible for collecting the samples and submitting the results to the municipality. The sample must be analyzed at the State Lab of Hygiene or another certified laboratory and paid for by the well owner. If a well inspection is being done the inspector could collect the samples. The system operates on the principle that most persons are honest and support prevention of contamination of groundwater which is used as the municipal water supply. Spot checks by the municipality can be used to assure honesty.
Labs can detect fluoride or chlorine which are added to many municipal water systems.
Well inspections should be done by licensed well drillers or licensed pump installers or trained sanitarians. Any person may legally do the inspection as long as they are competent and knowledgeable about code and ordinance requirements. Typically, the primary justification will be the high cost of purchased water for large water usage associated with lawns, gardens, car or truck washing, etc. The municipality must exercise good judgement in interpreting this aspect. The requirements of the ordinance must be met by all well owners.
