Production tends to be spotty, since it depends upon hitting a series of crevices. There may also be areas that were old streambeds, and in which alluvium has been deposited; these areas tend to have higher production. A number of rural residences have wells; most are in the 100 to 200 ft. range. A well to supply Norwood should have a production of about 50 to 100 gpm consistently to be cost effective. According to local residents, there is a band of high well production about 200 yards wide running from west to east near Norwood. Four potential wells are shown on Figure V-B. Estimated production based on verbal information from owners is as follows: Jack White well - 50 gpm Old Town well - 0 to 100 gpm Fitts wells (2) - 20 and 80 gpm each pioneer Village well - no information It appears that the maximum production that could be expected from a well is 50 to 75 gpm. The only way to verify the actual production of each well is to test pump it over approximately a one week period. The draw-down in adjoining wells and recovery should be measured during the test. Advantages of well water are: it is high quality water and would be available in winter months. Since it would not have to be connected to the water treatment plant, it could be located almost anywhere. Disadvantages of a water well system are: 1. It is a separate source of water and therefore, must be tested separately from the main supply. Testing can be expensive. 2. All of the water from the well must be pumped. 3. It is another facility to maintain, i.e., a chlorinator must be checked daily. 4. It is difficult to predict the long term reliable supply of a water well. Occasionally, production tends to drop off with long term pumping. V-s
