Town of Yarmouth Board of Health 1146 Route 28 South Yarmouth, MA 02664 RE: 6 Smiths Point Road,West Yarmouth -Health Code Variance Request To The Board of Health, On behalf of the Albright family,the owner or 6 Smiths Point Road, West Yarmouth,we are requesting two variances relating to potable well setbacks. The water supply for 6 Smiths Point Rd. (locus)has been for years a shared well among three properties with appropriate agreements and easements of record. The Albrights,for a number or reasons, one of which is to unburden and reduce demand on the off- site common well, seek an independent water supply. A suitable source for this water supply is a well located on locus installed by a previous owner as a casing with screen but never used. The well likely was placed to investigate water quality for a potable source but this information is unavailable to us. The existing well casing and screen has been evaluated by Atlantic Well Drilling with basic well information listed here. The 4 in. diameter well was set at a max. depth of 32.5 ft. 16 ft. below the static groundwater surface level. We understand a typical 4 ft. screen was installed. Pumping test rate was 30 GPM sustained with approx 2 to 3 ft. drawdown. The water sample quality tests are good quality for potable sources and are attached with this application. A site plan is attached showing the existing conditions and the well now proposed for potable/domestic use. • The subject well is 146 ft. and up gradient(groundwater gradient) from a septic system SAS located at 53 Uncle Roberts Rd. This condition requires a 4 ft. variance from the 150 ft. requirement. • The subject well is located 132 ft. up gradient from the existing septic system SAS located serving locus located on a separate parcel on the opposite side of Smiths Point Road. This condition requires an 18 ft. variance from the 150 ft. requirement. Of note is the observation that both wells are located in a general direction that places them in positions where groundwater flow is logically flowing toward the coastal interface, from the well toward the septic SAS. Water quality and production of the 1 subject well is excellent and highly suitable for domestic use. The residence may employ a pH neutralizer and filter apparatus which is advisable for most current Cape Cod ground water used domestically. The circumstances of the well to SAS layout allow for a reasonable conclusion that with the requested relief granted,the circumstances will provide for an equal or better level of environmental protection as compared with a condition where a 150 ft. separation was met but with a reversed groundwater gradient. Thank you for your consideration of the request. Sincerely, Cape Cod En 'nee g,Inc. ., ./ Robert Perry, P.E. 2 il ENVIROTECH LABORATORIES, INC.
