This approach allows staff to have a "snapshot" of the sentinel wells on the perimeter of the entire <br />group of properties to determine if there is groundwater contamination, loss of yield or other <br />definable outside influence problems. <br />Study Methodoloey #2: <br />Offer bacteriological and inorganic chemical water samples for any home in the neighborhood <br />through a direct mailing with an application enclosed. We would then allow the residents a 10-14 <br />day window to return Che completed application. It is possible that residents from all 82 homes <br />would return the application, but given our recent experience in the Mill Creek area, we do not <br />expect such a complete response. We estimate we will receive at least .30 applications from the <br />residents if all 82 homes are part of the study group, <br />Should we find abnormal sample results for certain parameters in the suite of samples, we will <br />offer to videotape the wells at those affected homes to search for well construction or aquifer <br />problems, Generally those parameters are turbidity (cloudiness of the water), suspended solids, <br />iron and fecal coliform bacteria, As in Method #1 above, the homeowner will need to consent to <br />and possibly participate in the well camera portion of the study if needed. <br />GENERAL <br />During the water sample collection visits, each resident will be provided with educational literature <br />on wells, septic systems and other health department services, This is similar to the packets <br />provided to others in the county during environmental education days and other specialized <br />studies. <br />Staff will prepare a report summarizing the activities with discussion for presentation to the <br />community, the Board of Health and the Board of County Commissioners. <br />COST ESTIMATES <br />We estimate we can sample wells at 15-20 homes per staff day, The direct cost for that service is <br />based on average salary for field Environmental Health Specialist and daily mileage, <br /> Field Field time for Report <br /> Time for Sample <br />videotaping (2 Preparation <br /> samples kit <br />d <br />i Mileage ($42/hour) TOTAL <br /> ay w <br />th Z <br />Per <br /> @ costs staff) <br /> $32/hr <br />Method #l (Sample <br />and videotape six $128 240 $1,5.36 $62 $252 $2,218 <br />wells <br /> <br />Method #2 <br />(Assuming a1182 <br />applications $1,024 $.3,280 $2,560 $160 $420 $7,444 <br />received and 10 <br />wells videota ed <br />
