There are many ways to protect public water supplies, and communities vary greatly in the extent to which they protect water supplies. We would like your opinion on how well you feel the drinking water supply in your community is protected from contamination.
Study the chart below and circle one letter (A, B, C, or D) that corresponds to how safe you feel about your household drinking water supply.

One way to prevent pollution of the supply is to establish an areawide special water protection district. This district would develop and implement pollution prevention policies specifically designed to suit your community's needs. Those in the district who would benefit from the increased protection would make an annual payment, which would be added to their water utility bill.
We are interested in discovering what you would be willing to pay, in higher water utility bills, per year to increase the level of protection for your community water supply. Take into account your household income and the fact that the money would have come from some part of your budget.
Using the payment card below, please indicate how much you are willing to pay, per year, to go from your present protection level, which you indicated on the chart in Question 1, to the highest level (For example, if you feel "SOMEWHAT SAFE" now, what would you pay to move to "VERY SAFE")? Circle one dollar range as your annual payment.
