General This site was opened as a Class II sanitary landfill in 1976. Waste was last received in 1984 and fianl cover was placed prior to December 30, 1984. According to Levy County personnel, only household garbage and con struction rubble were buried on this site. The County "controls" this site by virtue of a land lease between themselves and Ms. Micki Borowski. Currently, the site is used as a pasture and cattle are grazing here. The site is located approximately 2 miles east of the Town of Williston. The surrounding property to the north nad east is being used as pasture for cattle. Residential development occurs within 1500 feet to the south of the closed landfill. There are also some single family homes lying approximately 500 feet west of the site. The surrounding property is zoned R-3 and is classified as prime agricultural land by the Levy County Comprehensive Plan prepared in 1978.
Regional Geology & Hydrogeology The Geology of the area of the landfill site typically consists of limestome lying fairly close to the surface with a layer of clayey sands of varying thickness overlying it. The clayey sands which crop out in Gilchrist, western Alachua, and Levy counties belong to the Alachua Formation. The Alachua is of upper Miocene, possibly Pliocene age, and clayey sands, and sandy clays. The Alachua has been mined in many localities in the map area for the hard rock phosphate that is commonly found in its lower section. The top of the Florida Aquifer occurs at an elevation of approximately 70 feet N.G.V.D. in this vicinity (per 1979 map prepared by D.N.R. in conjunction with S.R.W.M.D. entitled "TOP OF THE FLORIDAN AQUIFER OF NORTH CENTRAL FLORIDA") However, a map prepared by SWFWMD depicting the Potentlometric surface of this aquifer shows the potentlonetrlc surface in this area to be at an elevation of approximately 53 feet N.G.V.D.. This probably indicates a high potential for recharge to the Floridan Aquifer in this area.
Site Specific Geology & Hydrogeology The completion reports for the existing wells reveal the diverse litho logy of the Alachua formation on this site. Llmerock was excavated during the digging of the cells at this site. Water was encountered at a depth of approximately 4~0~~feet, which is in agreement with the SWFWMD potentlometric surface map. Most probably, no confining layer exists between the bottom of the cells and the top of the Floridan Aquifer. However, there seems to be approximately 25 feet between the bottom of the cells and the high water surface in the aquifer. Willlston Landfill Page 2
Physical Characteristics The cells within the landfill are all approximately 10' to 12' deep. Refuse was compacted with a bulldozler equipped with a landfill blade. Cover was applied at regular intervals. A minimum of 2 feet of native sand was applied as final cover. The disturbed areas have been graded and seeded with bahis grass. This grass has sprouted well enough to graze cattle on. How ever, there are some signs of minor erosion in areas where the grass has not come in.
Recommendations Four monitoring wells shall be Installed at the locations indicated on the attached survey. These wells should all be drilled to a deptbof 50 feet which will place the screened interval below the potontiometric surface of the Floridan Aquifer. These wells shall be constructed according to the details as shown in attached Exhibits A & B. Samples will be collected from each well on a quarterly basis. Static water levels in each will be measured prior to purging the well. These levels will be measured by inserting a steel tape on the casing and measuring the distance from the top of the well casing to the free water surface. After taking this measurement and prior to sampling, the well will be purged and a minimum of four (4) well volumes evacuated from the casing. A hand-actuated pump constructed of PVC and equipped with a double foot-valve will be used to purge the wells and to collect water quality samples. Water quality samples will be collected by an employee of Mills Engineering Company or by an employee of Levy County under the supervision of Mills Engineering Company personnel. This same person will also measure the static water level in each well. Ste rilizing sample containers will be obtained from the laboratory which will perform the tests on the day prior to collecting the samples. The samples will be returned to the laboratory immediately after they are collected. The transportation and presevation of these samples will be in accordance with the laboratory's Instructions. The analytical methodology and detection limits that the laboratory must adhere to are attached as Exhibit C. The parameters to be monitored Include: primary and secondary drinking water standards, total organic carbon, volatile organic carbon, and specific conductivity. The site should also be re-seeded with bahia grass and fertilized. Peri meter ditches should also be dug to intercept runoff. Upon acceptance of this plan by D.E.R., the wells will be installed and testing will begin. Monitoring will continue for 20 years or until D.E.R. recommends it cease. ^=__ F_

NO. 5 WILLISTON, FLORIDA PHONE (904)486^311 Extension 32 INGLIS LANDFILL GENERAL: This site was opened & began to receive waste in 1976. Waste was last deposited in 1984 and final cover was placed prior to 30 December, 1984. The site operated as a Class II Landfill. According to Levy County personnel, only household garbage and construction rubble were buried at this site. The County "controls" this site by virtue of a land lease between themselves and the Southwest Forest Industries. The site is bounded on the North by SR 121 & by planted pine forests on all the other sides. The surrounding property is currently zoned A-1, but is classified as a development area in the Levy County Com prehensive Plan prepared in 1978. The surrounding property is largely undeveloped at this time. REGIONAL GEOLOGY & HYDROGEOLOGY The Landfill site lies in the Southern quarter of that portion of the Brooksville Ridge lying North of the Withlacoochee River. The Brooks- ville Ridge is a lin%r feature about 110 miles long that is divided into two sections by the Withlacowee River at Dunnellon. The northern port ion is some 50 miles long and varies in width fron 4 to 6 miles. The ridge is composed of a predominant sand lithology encompassing the cen tral map from Dunnellon to east-central Gilchrist County. The thick sands of the Brooksville Ridge are believed to be a result of the Wico mico stand of the sea at an approximate elevation of 100 feet. Under lying these surficial sands are clayey phosphatic sands, and it may be largely a result of these underlying materials that the northern portion of the Brooksville Ridge exists as a highlands today. Due to the insol ubility of these sediments, they were less prone to lowering by solution. Consequently, they exist as a highlands, while the more soluble limestone plains surrounding the ridge were reduced to lowlands. The Floridian Aquifer lies under the sand and clay deposits mentioned above. The top of this aquifer is at an elevation of approximately -20 feet N.G.V.D. (per 1979 map prepared by D.N.R. in conjunction with S.R.W.M.D. entitled "Top of the Floridian Aquifer of North Central Florida"), Another map prpared by S.W.F.W.M.D. showing the potentiometric surface of the Floridian Aquifer as it existed in September 1983 shows the potentiometric surface in this area to be at an elevation of approximately +50 feet N.G.V.D. page 2 INGLIS LANDFILL: SITE SPECIFIC GEOLOGY & HYDROGEOLOGY The completion reports for the two wells which were installed on this property both show the following lithology: 0-20 feet : sand 20-45 feet: sandy clay & clayey sand Limerock not encountered The only remaining well (#2) was dry in April 1985, the last date it was checked. This indicates that the sandy clarets as a confining layer due to the fact that this well is screened at an elevation of app roximately 45' NGVD well below the potentiometric surface of the aquifer. It also indicates that the surficial aquifer exists only temporarily, ie, after periods of heavy rainfall. Therefore, the Floridian Aquifer is' the only aquifer of significance underlying this site. Depth to this aquifer from the ground surface is approximately 90 feet, according to best available records. However, there are no soil boring to confirm this. — PHYSICAL CHARACTERISTICS The cells in the landfill are all approximately 10' to 12' deep. Refuse was compacted with a bulldozer equipped with a landfill blade. Cover was applied at regular intervals. A minimum of 2 feet of native sand was applied as final cover. The disturbed areas are now overgrown with weeds. The area has many slight surfa.Cfi_d_epressions and exhibit ing-some signs. of erosioTi. This information was provided by Levy County personnel. RECOMMENDATIONS Four monitoring wells shall be installed at the locations indicated on the attached survey. The depths of these wells shall be approximately 45 feet. These wells shall be constructed according to the details as shown in attached Exhibits A & B. Samples will be collected from each well on a quarterly basis. Sta tic water levels in each will be measured prior to purging the well. These levels will be measured by inserting a steel tape in the casing and meas uring the distance from the top of the well casing to the free water sur face. After this measurement and prior to sampling, the well will be purged and a minimum of four (4) well volumes evacuated from the casing. A hand-actuated pump constructed of PVC and equipped with a double foot- valve will be used to purge the wells and to collect water quality sam ples. Water quality samples will be collected by an employee of Mills Engineering Company or by an employee of Levy County under the supervision of Mills Engineering Company personnel. This same person will also measure the static water level in each well. Sterilized sample containers will be obtained from the laboratory which will perform the tests on the day prior to collecting the samples. The samples will be returned to the laboratory immediately after they are collected. The transportation and preservation of these samples will br in accordance with the laboratory's instructions, page 3 INGLIS LANDFILL The analytical methodology and detection limits that the labora tory must adhere to are attached as Exhibit C. The parameters to be monitored include; primary & secondary drink ing water standards, total organic carbon, volatile organic carbon, and specific conductivity. The site also needs to be graded to faciltate the removal of stormwater. The site will have a 1% or 2% grade to promote runoff. The site will then be seeded with scanified bahia seed at the ra1:e of 150 Ibs/acre. This will be mulched & fertilized also. Upon acceptance of this plan by D.E.R., the wells will be installed and testing for the required parameters will begin. Monitoring will continue for 20 years or until D.E.R. recommends it cease.
