Yoder, M.D. '' 2 SUBJECT: Evaluation of Existing Sanitary Landfills - in Weld County as Hazardous Waste Disposal Sites . September 1975 I 'm please to transmit the above report prepared by the Colorado Department of Health. You will recall that over a year ago I promised that we would secure the cooperation of the CDH in meeting the need which exists for our County. This will help reinforce my previous recommendation, that it would be wise for the County to consider locating sanitary landfill areas in geologically suitable areas conven- ient to our Weld County population centers. We could also in event of County owner- ship, which includes the right of eminent domain, acquire landfill sites located where they should be instead of where land might be commercially available. This would also permit the consideration of low level radiation waste disposal which would be appro- priate for our County,which has the only nuclear power reactor in the State of Colorado. It would also meet the standards of the State Highway Department for a site to deposit accidental spills along highway rights-of-way and railroad rights- of-way. Unfortunately, this type of accidental spill is occurring with increasing frequency. Mr. Glen Paul and I as well as members of the Colorado Department of Health staff are available to meet with the Weld County Commissioners at a mutually con- venient time. cc: Catherine Benson, Chairman, Weld County Board of Health Barton Buss , Director, Management and Budget P.S.

Purpose and Scope This report was requested by Dr. Yoder, Director of the Weld County Health Department to designate a disposal site in Weld County as a hazardous waste site. The purposes of this report are to evaluate the suitability of existing sites and facilities and to make recommendations for the location and operation of an approvable hazardous waste site and facility. II. Conclusions 1. Pesticide containers from applicators and residues from pesticide formulators are sources of hazardous wastes in Weld County. 2. All existing landfill sites are located in aquifer re— charge areas, flood plains or irrigated. farmlands or near population centers. Surface and ground watei pollution or air pollution can result from improper disposal of pesticide containers at any of these sites. A report and plan for receiving and disposal at a selected site has not been developed. 3. Liquids and residues from pesticide use, formulation and container washing operations are hazardous waste requiring special storage processing and disposal. D. Hazardous waste, not acceptable for disposal at a specially designated landfill site, is a responsibility of the generator. 1 5. A feasibility study for locating, designing and operating a hazardous waste site and facility has not been made. The acceptable method of financing has not been determined. III. Recommendations 1. Disposal site operators should be instructed not to receive hazardous waste materials, at existing disposal sites, unless the site has appropriate authorization from the Weld County Commissioners. The amounts receivable should be minimized by advising the generator to use these wastes for the intended purpose or neutralizing at the source. 2. An engineering report and operation plan should be developed and approved by the Department for a disposal site designated to receive empty pesticide containers. IL should consider hydro-geological conditions; sources, types and condition of containers; method of disposal, records and monitoring procedures. 3. Left over pesticides, residues from pesticide formulations or container washing operations must be excluded from disposal sites unless authorized by the County Commissioners. A prerequisite for authorization is an engineering report 'and operation plan approved by the Department. 4. The generator of hazardous waste not received at designated landfills should provide for on site storage facilities and transportation to appropriate sites in another State. 2 • 5. It is recommended that a consulting engineering firm with competance in chemical engineering be retained by the Weld County Commissioners to determine the feasibility of providing a hazardous waste processing facility and disposal site in Weld County and inves- tigate financing alternatives. IV. Discussion Hazardous waste is any waste or combination of wastes that poses -a substantial danger to human, plant or animal life. -Special precautions must be taken in handling, processing and disposal of these materials. They may be toxic chemicals; acids or caustics; explosives; or flammables. A review of sources of hazardous waste generated in Weld County indicates there is a need to 3i r _ f hazardous material including pesticide residues and containers from formulators and applicators. Initially, an engineering report and plan for disposal should be developed which considers sources, quantities and types of hazardous waste. After review by the commissioners, recommended approval ty this Department, comments of the Weld County Health department and public hearing, a proposed site and facility may be designated. The -existing landfill sites were designated prior to the requirement for engineering reports and -operation plans. Therefore geological, hydrological and operational data nn specific sites are lacking. Available data are inadequate for this -Department to approve any of the existing sites as suitable for hazardous waste processing and/or disposal. 3 The problems associated with improper -land disposal of hazardous wastes have not been recognized by the public, although damages may be severe and difficult to remedy. Air and water control programs have diverted many of these materials to the land for disposal. The _problem is manifested in groundwater contamination by leachate, air pollution by open burning, evaporation, and wind erosion; _poisonings by direct contact and through the food chain; fires and explosions at land disposal sites. Nationally, it is estimated that hazardous wastes comprise only 5 -percent of the total solid waste generated. However, the environmental impact is much greater. Approximately 4-0 percent by weight of these wastes are inorganic, 60 percent organic. It is alsoestimated 90 percent exists i.^ liauid or semi-liquid form. There are damage reports of arsenic Toisoning in Minnesota from la.ndfilling grasshopper bait contamination of soil, surface and groundwater on farmland in Illinois from disposal of metal finishing wastes on land; a fatality at a New Jersey landfill caused by exploding chemicals, to name a few, Some are a result of disposal practices 30 years ago and others a result of current disposal practices. General categories of hazardous wastes are toxic chemical, k flammable, explosive, and -hiological. These can be in form of solids, liquids or gases. _Technology for the proper treatment and disposal of -hazardous waste is generally available. However, the lack of regulation and economic incentive discourage the use of acceptable treatment and land disposal z methods. Treatment processes include volume reduction, component separation, detoxification, disposal and storage. Methods of disposal -on land include mixing with soil for bio-degradation, aerobic or anaerobic ponds, _filtration through natural or imposed media, encapsulation and permanent disposal. The use of a deep well injection method for disposal is an alternative which requires considerable study and investigation prior to approval. The sources, amounts and types of hazardous -waste generated in the "front range corridor" have -not been surveyed. Presently, -the requirement is to transport hazardous and -toxic wastes to -appropriate disposal sites in other States. However, some questionable materials are being currently received at -the Lowry Pombing Range -site in Arapahoe County. Several chemical Fires have occurred in the chemical disposal pits recently. It is estimated that 3 million gallons of industrial sludges are -disposed of annually at this site. The portion considered hazardous or toxic is not known. Should -a hazardous waste processing and disposal site be designated 5 in Weld County, it may receive -much of -these materials laresently teing received et Lowry andother sites. These increased quantities may improve the feasibility for recovery of materials. The Trocedures for designating a hazardous waste processing and disposal site by the -Board of County Commissioners are the same as for a sanitary landfill. -However, the required engineering report and operation _plan must include sufficient data to ensure compliance with stringent criteria for hazardous waste processing and disposal. C? The following is an evaluation n f existing designated landfill sites in Weld County, as to the suitability of these sites for disposal of hazardous materials. Many -of these waste materials can be extremely toxic, water soluble, persistent after disposal, and dangerous to operating personnel, persons using the dispersal site or in vicinity of the site. V. Hydrological (valuations of Existing Sites This phase of the screening and selection process will include -a map and literature survey end a preliminary analysis of existing landfill facilities in Weld County. This study will try to determine the feasibility of designating an existing landfill as a hazardous waste disposal site. She screening process is not as a detailed engineering report. 6 Criteria. to be used in evalua,ting existing sanitary landfills: A. Proximity to flood plains. B. Proximity to aquifer recharge areas, _including surface waters and streams. C. Depth to -water table, including nearest use or subsurface discharge of underground water. D. Precipitation and drainage. E. Wind -erosion potential and natural barriers. F. Seismic activity and faults. G. Proximity to growth areas. H. Transportation routes, accessibility, and security. I. AExisting land use. A. Proximity to flood. plains The overall drainage pattern in Weld Cc.2nty is dentritic resulting in a high degree of interrelationship between streams and rivers. Pollution of any part may result in pollution of -the whole, especially during periods of flooding. Information on flood plains was provided by the Weld County Planning Dffice. Their map is based upon soil association data. Therefore, a detailed engineering study is necessary in selection of a hazardous wants disposal site and facility to insure adequate protection from flooding. 7 B. Proximity to aquifer recharge area, including surface waters and streams. All aquifer recharge areas must be protected from the possibilities of pollution. Pollution of a recharge area may affect a user miles away. Care _must be taken not to diminish the capacity or water quality of the -aquifer, for in many areas in Weld County underground water is the major source of water for agricultural and domestic purposes. Inorganic solutions pass readily through soil end, once introduced, may not be removable. Because natural dilution -is slow, induced flushing is expensive, and treatment is impractical. The effects of pollution may continue for a long period -of time. In Weld County the major aquifers are situated in alluvial valleys, comprised of mostly sand and gravel underlying the major streams. Since these areas are locally recharged and form a hydraulic link with the streams flowing over them, careful investigation -must be made before disposing of any hazardous waste material to insure underground water storage is not irreparably damaged. Information for our preliminary investigation was provided through a generalized map of aquifer recharge areas supplied by the Colorado Land Use Commission, recharge areas to include major reservoirs and streams. We feel that not only should these areas be avoided, but also a buffer zone to extend beyond 8 the zone of recharge should be -considered. prior to selecting a site a thorough study of surface water hydrology must be under- taken. Such a study should include rates and directions of surface runoff, historical -flow on surface streams, ditches, drains, and canals, and all other pertinent hydrological data on -other surface waters. C. Depth to water table, including nearest use or subsurface discharge. Acceptable conditions for the location of a hazardous waste disposal site include -an area with essentially no water table. A geological investigation of a hazardous waste site will be necessary to determine the depth to water table, including nearest use or subsurface _discharge, and effective porosity and permeability of the -surrounding media. Naturally, the greater the distance any possible leachate from the landfill has to travel, the less cha.ace of any possible pollution of any- rater source. However, in dealing with hazardous materials, great care will have to be taken to assure that any materials not readily removed by the major mechanisms of decreasing concentrations in the subsurface, be contained. For our purposes, the major mechanisms involved in decreasing concentrations of dissolved solids in an effluent are sorption and bacterial action. Sorption is the attachment of dissolved ions to rock minerals, generally by electro-bonding forces. Bacteria use any organic material in the effluent for food. Earth materials with a high percentage of clay sized particles are the most efficient in attenuating _dissolved solids from wastes. 9 It would be desirable to contain this leachate in the most efficient and economical way. A natural subsurface high in clay materials will greatly seduce the chances of any pollutant reaching surface or groundwater. Therefore, the acceptable location of hazardous waste site will . be located in an area far removed .from wells or springs and with e. sufficient depth and quality of underlying material capable of containing any leachate escaping from the site. A thorough study of geological and hydrological conditions will be necessary in evaluating a possible hazardous waste site. This study should include but not be limited to: -soil down to the bedrock formation, depth and thickness of all formations underlying the possible site, dip and strike of all subsurface formations, data- on all possible water tables, annual fluctuations in these water tables, piezometric surface and gradients, and permeability and porosity of all major shale between ground isur£ace and bedrock. D. Precipitation and discharge. The acceptable areas for hazardous waste locations will be those with low permeability materials in composition. Requiring that the landfill be located in these areas will not be sufficient if the effects -of precipitation and drainage are not considered. The county has less than 15 inches of precipitation a year, mainly in the form of thunderstorms. Locally, severe weather can result 10 in large amounts of precipitation in short periods of time. Natural drainage must be diverted around the perimeter of the landfill. Naturally, the less water to enter the fill area, the less leachate produced. It slay be necessary to provide facilities for the collection and treatment of leachate in an area of low permeability. E. Wind erosion -potential and natural barriers. As stated in the regulations _'or solid waste disposal sites and facilities "the design shall contemplate the location and construction of the disposal site and facility in such a manner as will eliminate the scattering of windblown -debris. All solid wasLes discharged at the site shall the confined to the site and -any material escaping from the active discharge area shall be promptly retric:•cd and placed in the active discharge area." Not only will the potential site have to be adequately fenced, but also a survey will be needed to determine potential -.*ind erosion, frequency, and velocity of wind. Natural land barriers ran minimize or accentuate the effects of wind. Land formations may -either help block out the force of the wind or create -natural wind tunnels thus increasing its detrimental effects. Hazardous waste maybe in a form that can become airborne. F. Seismic activity and faults. Observations reveal that earthquakes have a variety of effects • 11 on groundwater. Most spectacular are sudden -rises or - -ails of water levels in wells, changes in discharge -of springs, appearance -of -new springs, and eruptions of crater and mud out of the ground. _Fractured rocks and faults are relatively inefficient in removing dissolved solids because the surface area-provided 2'or sorption is so small. Faults in underground formations have the undesirable capability of extending them- selves 'to the surface, thus allowing for the possibility :of leachates being transmitted into the subsurface et a relatively high concentrati-on. Jbr t₹>.ese reasons, it will be necessary to compile a report of the aei-smic activities in the area under study aver a long period of time and to investigate subsurface geology -for the possibility of large f-aults. If we consider the Pierre shale as a _possible location, major faults could probably be recognized by any large displacements or offsets between the contact of the shale and overlying or surrounding formations. Minor faults could probably not be recognized because the weathering may obsrnre any evidence of fault. Also, clay may seal the fault to any movement of water along the fault. G. Proximity to growth areas. Weld County has shown a great potential growth, especially in the urbanized areas. The Weld County -Planning Office has compiled a map indicating existing urban areas and future town • 12 growth areas. It would be desirable and necessary to locate a possible hazardous waste site well beyond those areas of -potential growth. Although strict guidelines as to the disposal of these waste materials will be followed, one must not over look the possibility of spills, leachates, and the mixing of potentially incompatible waste materials. Due to the hazard -of the possible release of toxic substances, however small, it is imperative these sites be located where the possibility of these toxic materials coming in cont-act with humans is minimal. H. Transportation routes, accessibility : and security. The location of a hazardous waste site should provide for convenient and safe access from the major generators of the hazardous material. Access routes should provide orderly and efficient traffic flow to and from the site and within the site The site should be located far enough from a major thoroughfare to ensure the safety of the people and yet be close enough to allow easy access to the site without danger to the cargo and driver. The site should be located in such an area as to provide for that security necessary to prevent trespassing and vandalism. I. Existing land use. As stated in the Weld County Comprehensive Plan "The land of Weld County has always been bounteous to its farmers and to the people of Colorado and the nation. Weld County ranks first in agricultural productivity of all counties in Colorado and second of all counties in the nation. 13 The 1969 U. S. Census of Agriculture shows that the value of all farm products sold in Weld County totaled $317,410,295 and accounted for 30% of all farm products sold in Colorado. Weld County has long been known as -a breadbasket for the people of Colorado and the United States." This rich agricultural land must be considered a major asset to the State of Colorado and the United States es well. All care must be taken to insure that none of this rich farmland is harmed or destroyed through inadequate planning. For our preliminary survey we are using a general soil map of Weld County provided by the Weld County Planning Office. This is a generalized map compiled from detailed and reconnaissance soil surveys and in part from interpretations. For these reasons, when selecting a possible site_for the disposal of hazardous wastes, a detailed soil map 'need :be used along with on-site descriptions for more detailed • decisions. We will limit our survey to those areas not used for irrigated agricultural purposes. ' J. Map Explanation There was no complete -map of Weld County taking into consideration 1 all the factors previously discussed. Information had to be gathered from many sources, and -most of that was at best in— complete. Maps and U. S. Geological Survey Water Supply Papers 14 • were provided ty Stephen D. Schwochow and David C. Shelton of the Colorado Geological Survey and John C. Romero of the Division of Water Resources. All existing landfills are located in undesirable areas for the disposal of hazardous waste materials. The area most desirable would be that area in the Pierre shale in the Southeast corner of the Weld County panhandle. Preliminary investigations indicate this area: (1) Is not located on a major flood plain. (2) Is not an aquifer recharge area, drainage would be to the NW. (3) Has essentially no water table, except those areas in which wells are drilled into the overlying sandstone. (4) Has no unusual problems with precipitation or drainage. (5) Has no unusual problems with wind erosion. (6) Shows no evidence of it being an area of seismic activity or severe faulting. - ! (7) Is not located near any large cities or major growth areas. (8) Is fairly accessible by the Burlington Northern Railroad to the NW and by Highway 14 to the East and West and by Highway 71 to the North and South. (9) The physiographic region to be one of shallow to deep rolling hardlands and nearly level hardlands. Land Resource Areas of Colorado describe the area as follows: ' f 15 { (1) -Elevations range from 3,500 to 5,500 feet (2) Relief nearly level to gently undulating with slope-s From 1 to 5%. Numerous small areas crf rolling topography with slopes up to 8%. (3) precipitation: 15 to 17 inches annually. May be problems with torrential _downpours. (4) Land Use: Primarily dry f-arming, more rolling 1-and used for grazing. (5) Wind erosion the dominant type on nearly level dry lands. (6) Native vegetation consists mainly -of blue grama with moderate amounts of buffalo grass. Any one factor making-the area undesirable is reason for elimination, however most were -eliminated by twoor more factors. YELLOW AREA - not a specific geologic-al formation, however, with the aid ofmaps supplied by Weld County Planning Office, this area was eliminated for possible hazardous waste site. The criteria for elimination was -the following: - (1) proximity to flood plains. (2) Proximity to aquifer recharge areas. (3) Proximity to growth areas. (4) Land use, eliminating those areas of irrigated farmland. Through maps supplied by the Mate Geologists Office and descriptions from U. S. Geological urvey Water Supply Paper 1367, these areas were eliminated due to undesirable geologic conditions. ICE (Black) - Fox -Hills Sandstone - medium yellowish-brown calcareous loo marine sandstone interbedded with dark-grey to black sandy shale and some massive white sandstone. The sandstone is loosely -to moderately cemented and contains concretions. The maximum thick- ness in this area is about 400 feet. Although the Fox Hills generally yields less than 15 gpm to wells and springs, yields as much as 350 gpm from wells have been repotted. Except 1n the out- crop, the water is under artesian pressure. Q (RED) - Dune sand, valley fill, and terrace deposits - Data from ground water, South Platte River Basin. The pediment deposits are of arkosic sand and gravel with minor amounts of red clay, with a yield of 2 to 5 gpm to wells. Although yield very small, sand and gravel have a high degree of permeability, thus possible pollution of nearby water sources may result. The dune sand deposits and all alluvium are mainly comprised of sand, silts, gravel, and clay. These deposits yield moderate to large quantities of water to irrigation, municipal, industrial, domestic, and stock wells. For convenience, all quaternary deposits of unconsolidated material were mapped as one unit. KI (BLUE) - Laramie formation - Upper 400 feet consists of olive gray silty shale; contains lenticular beds of sandstone and numerous carbonaceous beds of clay and seams of lignite. Lower 200 feet con- sists of blue-gray silty shale, several relatively thin beds of sandstone and fairly thick beds of subbituminous coal. At the base 17 is a thick persistent -sandstone, immediately above are two thinner sandstone beds that locally coalesce- with the thick sandstone. Some of the upper beds of sandstone and the basal beds of sandstone yield small to moderate supplies of water to industrial, public- supply, domestic, and stock wells. For this reason, this area would be undesirable. TA (ORANGE) - The Arikaree Formation consists of gray to brown fine to medium -sandstone that contains hard calcareous lenses and pipings. The sandstone is massive to poorly bedded and loosely to moderately cemented. It probably does not exceed $0 feet in thickness. The Arikaree yields small amounts of water to wells in adjacent areas. TO (PURPLE)- The Ogallala formation consists of beds and lenses of stream deposited gravel, silt, sand, and clay, and contains caliche. The material is loose to well cemented with calcium carbonate; the well cemented beds are termed "mortar beds" from their resemblance • to concrete. Because the Ogallala was deposited on an eroded surface, it differs widely in thickness from place to place. The Ogallala yields small to moderate quantities of hard water to domestic and stock wells and springs and as much as 50 gpm to wells supplying the town of Peetz. TW (GREEN) The White River group consists predominantly of blocky variegated clay and siltstone, which contain beds of loose to moderately cemented fine to coarse sand. In places, the formation 18 contains hard siliceous channel sandstone and conglomerate. Joints and fissures may penetrate the beds locally, increasing the water bearing capacity. "Porous zones" in the upper part of the White River that extend under saturated unconsolidated deposits may greatly increase the water-bearing capacity of the beds. The White River differs widely from place to place. The White River Group generally yields as much as 30 gpm to stock and domestic wells and springs. In places where it is either extremely sandy or highly fractured, it yields as much as 1,400 gpm to irrigation wells. Acceptable formation: KP (BROWN) - Pierre shale consists of bluish- black marine shale and silt and interbedded tan to yellowish-brown sand and sandy shale in the upper part or transition zone. Many beds of bentonite and large blush-gray limestone concretions are present throughout the formation. The thickness of the Pierre shale ranges From an estimated 6,500 feet near Hardin, Colorado to 2,500 feet near Paxton, Nebraska. Pierre shale is usually considered to be a poor source of water. In some areas, however, artesian water may be obtained from lenses of sand within the shale. Recharge by infiltration of surface water is negligible, because pore spaces between the grains of clay, silt, and very fine sand in the Pierre shale are very minute. Water in quantities sufficient for irrigation, public supply, or industrial use is not available from the Pierre shale. Except for the localized sand lenses and the deep—lying Hygiene 19 sandstone member, the Pierre shale is relatively impermeable and little or no water can be obtained from it. Many stock wells are drilled into the Pierre shale where it is overlain by permeable dune sand. For this reason, it would be desirable to avoid areas of thick dune sand. Supplemental information: Reports on proposed waste disposal site near Limon, Colorado - Prepared for Chem-Nuclear Services, Inc. Prosser, Washington by Charles S. Robinson, Ph. D. , Consulting Geologist and Engineer, Denver, Colorado, October 1969. Conclusions and recommendations summarized from this report: (1) A complete detailed engineering and geological study must be undertaken, to include a careful examination of geology and ground water conditions at the proposed site. (2) Proof must be supplied that the underground waters will not be polluted or contaminated. (3) Excavation and recompaction of the shale will form an almost completely impermeable barrier or seal around the disposal trenches. • Engineering tests show a rate of water movement in recompacted Pierre shale to be only .2 feet per year. (4) Below a weathered zone of shale, the Pierre bedrock becomes quite impervious to the movement of water. Near Limon the shale extended to a depth of 3,000 feet. (5) Normal underground aquifers or water-bearing zones are not normally present in this shale formation. 20 (6) Analytic tests submitted by Mr. C. _S. Robinson indicate -a favorable ion exchange ratio by the weathered shale. This feature is a tremendous safety f-actor for waste disposal facilities. (7) Must insure minimum runoff enters the site. (8) The weathered shale has some permeability. • (9) Should have test well to monitor any movement of leachate from the site. (10) Samples of water, soil, and plants should be collected prior to disposing of wastes to furnish background data prior to operation. (11) Recommend determing the prevaling wind direction and average wind speed over the past year as background information.
