No. The law allows food to be sold or distributed at non-commercial functions such as an educational, religious, political, or charitable organization’s bake sale and pot luck supper.
For the most part no, although there are exceptions. Connecticut requires all food at public events be prepared in commercial kitchens. Exceptions include baked goods (cookies, cakes), and jams, jellies, and preserves made from fruit grown on a residential farm.
Well water should be tested yearly for basic water potability including total coliform bacteria, nitrates, nitrites, pH, odor, chloride, hardness, apparent color, sulfate, turbidity, iron, manganese and sodium. You may want to consider testing for radon also.
The only way to know that your drinking water is safe is by having it analyzed by a State certified laboratory.
Septic tanks are sized based upon the number of bedrooms. A 3 bedroom house requires a 1,000 gallon septic tank, 1,250 gallons for a 4 bedroom house and 1,500 gallons for a 5 bedroom house.
The Town of Killingworth requires that your septic tank be pumped at least every 5 years. Undersized tanks and poorly functioning systems will require more frequent pumping.
