|General Site Description:||A permitted, (closed in 2009) limited purpose, unlined demolition and land clearing debris landfill facility that has operated since approximately 1953. The landfill currently occupies an area of approximately 33 acres with a site development plan anticipating a full build-out of 43 acres. The 1200 foot long southern boundary of the landfill is setback from the Tualatin River approximately 75 feet.|
|Site History:||The landfill began operation in the mid 1950s, but solid waste facilities in the State of Oregon were not required to be permitted by DEQ until 1972. After the permitting requirements went into effect, Grabhorn Incorporated and obtained an operating permit for the Lakeside Reclamation Landfill from DEQ in 1972. The 1972 permit application indicates the landfill footprint was approximately 7 acres in area and the fill composed primarily of construction/demolition debris and tree prunings. Over the years, Lakeside has received DEQ authorization on a case by case basis to take limited amounts of non-putrescible, non-hazardous industrial wastes. However, since the Solid Waste Disposal Permit was issued for the site, periodic compliance inspections noted disposals of un-permitted materials, which were removed if required by DEQ. In 1987 groundwater monitoring Wells were installed to assess the landfill’s influence on groundwater quality. There have been several expansions of the well network and monitoring continues on a semi-annual basis. In 1990, with DEQ’s approval, Grabhorn Inc. began installing an evapo-transpiration (ET) cap on closed portions of the landfill. As of June 2011, the ET cover, vegetated with shrubs, poplar and pines trees now covers the full landfill footprint, although certain areas of the cover exhibit poor plant health. Since the late 1990s, a portion of the facility has been used for a composting operation that is permitted by DEQ under a separate solid waste facility permit.|
(9/24/07 HDL/SRS) Groundwater monitoring at the facility indicates historic and on-going releases of landfill leachate are impacting groundwater quality beneath and directly downgradient of the facility. Contaminant levels, in excess of screening levels considered protective of aquatic organisms, have been consistently measured in river-front wells located immediately downgradient of the landfill. These monitoring results suggest that groundwater contamination potentially threatens aquatic life in the Tualatin River.
Groundwater has been contaminated with concentrations of nitrates and arsenic, periodically exceeding Drinking Water Maximum Contaminant Levels (MCLs) protective of human health. It is uncertain whether the elevated nitrate levels are attributable to leachate releases from the landfill. Groundwater beneath the landfill, however, is not used for drinking water.
Groundwater concentrations of manganese, nitrate, arsenic, zinc, benzene, chloroform, 1,1-dichloroethane, tetrahydrofuran have periodically exceeded EPA Region 9 Tap Water goals for protecting human health.
Undiluted, groundwater concentrations of aluminum, copper, mercury, zinc, and possibly chromium (depending on oxidation state) have periodically exceeded the federal recommended CMC (acute toxicity) for freshwater aquatic life. However, groundwater undergoes substantial dilution as it discharges to the Tualatin and it is uncertain that contaminant levels in groundwater are sufficiently high to adversely impact the river ecology.
Groundwater concentrations of alkalinity, ammonia, chloride, pH, boron, iron, manganese, lithium, aluminum, barium, nickel, silver, vanadium, zinc, carbon disulfide, toluene, and xylenes have sporadically exceeded either DEQ's Level II Ecological Risk Assessment Screening Values for freshwater aquatic life or the federal recommended CCCs (chronic toxicity) for freshwater aquatic life. However, groundwater undergoes substantial dilution as it discharges to the Tualatin and it is uncertain that contaminant levels in groundwater are sufficiently high to adversely impact the river ecology.
In addition to construction and land clearing debris, DEQ approved of Lakeside’s acceptance of non-hazardous industrial waste sludge from the Tektronix wastewater treatment plant (1980), aluminum oxide grit used to polish Tektronix fiberglass circuit boards, copper-contaminated pre-filters from the Tektronix chelate fluoride ion exchange system, and copper-contaminated dust collector material from the Tektronix fiberglass circuit board drilling operations (1983).
Since Lakeside began operating under a permit DEQ Solid Waste permit compliance inspections have noted a variety of prohibited materials in the fill, including auto tires, a smashed auto body, cafeteria wastes, household garbage, a substance used for heat-treating metals, closed paint cans, oil filters and jugs of used motor oil, and electric fans. Other wastes that were approved for disposal at the landfill by DEQ included casting sands, baghouse dust, and slag from Western Foundry (ECSI #185), and chromium-containing sludge ash from the USA Durham STP. Casting sands from Western Foundry are known to have contained zirconium which has low level nuclear radiation. Dusts associated with Western Foundry operations have contained elevated concentrations of arsenic, cadmium, chromium, copper, lead, and zinc.
DEQ issued the site a Notice of Non-Compliance (NON) in 2002 for unauthorized disposal of 630 tons of contaminated soils and chromium-treated animal hide splits originating at the Frontier Leather site (ECSI #116). The soils and hide splits were subsequently removed and sent to Hillsboro Landfill for disposal.
Because of large volumes of land clearing debris, including tree stumps, multiple historic reports of small quantities of wet garbage (1978-85 compliance inspections; 1992 NON; 2002 NON, it seemed very plausible that the landfill may be generating methane gas. DEQ has required that the landfill evaluate gas generation using four probes installed in August 2007. Preliminary results demonstrate the need for at the least gas monitoring at the perimeter and around onsite structures. Evaluation will continue to determine the types of gas controls that the landfill will need.
(3/21/07 HDL/SRS) An examination of groundwater data and information collected over the last fifteen years indicates groundwater flows predominantly to the south directly discharging to the Tualatin River. Nearing the river, groundwater flow paths are deflected to the southwest, likely the result of leakage from holding ponds located in the southeast portion of the facility. Groundwater quality data indicates that groundwater beneath the landfill has been impacted by leachate seeping from the unlined waste disposal areas. Contaminants and general water quality impacts observed are predominantly non-hazardous in nature (with respect to human health). The most notable impacts are elevated levels of total dissolved solids (TDS), chloride, iron, manganese, and zinc and the depletion of oxygen. Low levels of several human carcinogens including tetrahydrofuran, benzene, and arsenic have also been intermittently detected in groundwater at river front monitoring wells. Historical detections of several inorganic contaminants, including selenium, appear to be the result of sampling and/or laboratory analytical artifacts which produced spurious data. The areal extent of groundwater impacts associated with the landfill is confined to the Lakeside facility property, although shallow groundwater contamination may also affect a relatively small area of a private property located immediately west of the landfill and adjacent to the Tualatin. Data indicates that groundwater impacts deepen towards the river extending to a maximum depth of approximately forty feet beneath the water table before discharging to the Tualatin River. An analysis of hydrogeologic conditions at the site concluded that no existing private drinking water wells located beyond the facility boundary are vulnerable to contamination emanating from the Lakeside Landfill.
|Manner and Time of Release:||
Groundwater contamination is a result of leachate and possibly landfill gas released from the unlined landfill. Some of the contaminants detected in groundwater may be present in leachate while others are naturally occurring in soils and have been solubilized and mobilized as a result of leachate and/or gas altering the natural groundwater chemistry. Static water level measurements at the site's monitoring wells indicate that contaminated groundwater is probably discharging to the Tualatin River. Methane (a component of landfill gas) is being generated within the landfill, possibly from the organic matter diposals at the site (tree stumps, land clearing debris, lumber, past disposals food wastes, and wet garbage).
In 2014 a porewater study was undertaken and findings indicate that very little contamination from the landfill is actually reaching the river. See the remedial action section for more details.
|Hazardous Substances/Waste Types:||Groundwater contaminants of concern at the site include metals (As, Fe, Mn, Zn), VOCs (benzene, tetrahydrofuran) and various water quality parameters (dissolved oxygen, pH, total dissolved solids). Methane is present in the subsurface within the landfill.|
The exposure pathway of greatest concern is the discharge of contaminated groundwater to the Tualatin River and its impact on aquatic organisms. The most vulnerable organisms are the invertebrates (clams, worms, aquatic insects) that occupy the benthic environment in sediments beneath the channel bottom. Degradation of Tualatin River water quality is unlikely due to the high degree of dilution that occurs when groundwater mixes with stream flow. Contamination of domestic and irrigation wells due to leachate releases is considered highly unlikely.
Methane concentrations and pressures within the landfill may be sufficient to cause subsurface migration of methane toward nearby structures and other confined spaces. Methane is flammable and explosive at certain concentrations within confined spaces. Lakeside's preliminary methane monitoring and assessment indicates, however, that methane is not migrating from the landfill to on-site or off-site structures. (6/29/11 BAG) Ongoing methane monitoring indicates current methane conditions are not posing hazards at the landfill.
Discharges of contaminated groundwater to nearby Tualatin River represent a potential threat to the river’s bird, mammal, and aquatic life populations.
No impacts to domestic or irrigation wells are anticipated.
If methane concentrations and pressures within the landfill are found to be sufficient to cause subsurface migration to nearby confined spaces, DEQ will require engineering controls and an appropriate monitoring program to protect human health and safety.
|Status of Investigative or Remedial Action:||
(9/24/07 HDL/SRS) The landfill is currently performing a remedial investigation of human health and environmental impacts. This investigation includes: 1) locating and evaluating the vulnerability of domestic and irrigation wells in the area, 2) determining the concentration and rate of contaminant migration into the Tualatin River, 3) evaluating impacts to aquatic biota in Tualatin River, 4) determining the effectiveness of the landfill cover. DEQ anticipates the remedial investigation will be completed in early 2008.
The landfill is also performing a methane gas investigation under the direction of DEQ’s solid waste program.
(6/28/11 BAG) Lakeside has completed the Feasibility Study to address the landfill cover and groundwater contamination underlying the landfill. DEQ will be proceeding with public involvement and remedy selection through the summer/fall of 2011.
In September of 2011 a volumetric pan lysimeter was built near the top of the SW face of the landfill. The lysimeter dimensions are 8 x 16 x 5 feet deep. The basin is lined with geotextile fabric and two young pine trees were planted within the lysimeter basin. The lysimeter is instrumented to measure soil moisture, runoff, and percolation. Local rainfall and transpiration from the tree is also to be measured. The purpose of the lysimeter is to determine if the landfill cover can reach the goal of limiting rainfall infiltration to 1 inch/year. The lysimeter construction was completed in 2011 but not finalized when the landfill settlement negotiations brought further construction to a halt.
(8/12/13 RKW/SRS) The Record of Decision (ROD) for the project was signed December 2, 2011. It calls for: 1) enhancement of the landfill's evapotranspiration (ET) cover, 2) hydraulic containment of the groundwater contaminant plume below the landfill, 3) appropriate treatment of the wastewater generated by plume control, 4) performance monitoring of all remediation metrics including the goal of limiting stormwater infiltration below the landfill surface to 1.0 inch of water annually and, 5) Contingency measures to modify the remediation approach through Adaptive Management.
Landfill cover maintenance continued during 2012 in spite of uncertainty about the fate of the landfill during settlement negotiation. Maintenance included tree thinning, pruning, mowing, weed control, and tree planting. Approximately 3,700 trees, largely ponderosa pine and some KMX pine (hybrid species), were planted in 2012.
A Consent Judgment between DEQ and Howard Grabhorn was filed April 17, 2013. The judgment terminates the landfill's Solid Waste Disposal Site Closure Permit (No. 214) and releases Grabhorn from liability for cleanup. Composting operations at the facility are not effected by the settlement. With a settlement fund of $7 million DEQ will be responsible for performing the remedial actions approved by the Record of Decision (ROD) including post-closure monitoring and evapotranspiration cover maintenance.
(12/18/13 RKW/SRS) Semiannual groundwater and landfill gas monitoring resumed in November 2013. A long term constant rate aquifer test, needed to plan and engineer the groundwater remedy, was completed in December 2013.
(10/14 RKW/SRS) An additional 7,400 trees (ponderosa pine, shore pine, hemlock, douglas fir, port orford cedar, grand fir, giant sequoia, alder, Oregon white oak, Oregon ash, and various shrubs) were planted on the landfill in April 2014. The summer of 2014 was unusually hot and dry and in spite of watering trees twice a month there was considerable mortality. More trees will be planted in early 2015.
Pore water sampling was performed within the sediments of the Tualatin River in fall of 2014.
(3/26/15 RKW/SRS) An additional 4350 trees were planted in early February. The primary species was douglas fir with additional shore pine, ponderosa pine, and sitka spruce. Also included were a small number of sequoia, vine maple, cascara, oceanspray, and red flowering currant.
(9/24/15 RKW/SRS) In the fall of 2014 a porewater sampling investigation was undertaken along the shoreline of the landfill as well as upstream and downstream of the landfill. Impacts to the Tualatin River from the landfill were surprisingly difficult to discern. The high iron observed in groundwater appears to precipitate out before reaching the river. Arsenic, barium, and manganese are elevated in background areas and suggest that the landfill is not a significant source of these metals. Chloride is the best indicator of landfill impacts but it is only observed above remedial action levels immediately downgradient of the most contaminated groundwater wells MW-3 and MW-10, at the center of the landfill face. Another round of porewater sampling is underway in the fall of 2015 to confirm results from 2014. See the report in the documents section.
(12/05/16 RKW/SRS) In the fall of 2015 porewater sampling in the Tualatin River was again performed along the face of the landfill to confirm results of 2014. Porewater sampling in 2014 occurred just after river stage had risen in response to the onset of fall rains while porewater sampling in 2015 was earlier in the fall after a very dry summer. Porewater results in 2015 were elevated in comparison with 2014 for chloride, arsenic, barium, calcium, iron, and manganese in some locations along the face of the landfill. It was concluded that river stage can play a large role in porewater concentrations. Higher water in the winter months leads to groundwater flow reversal and precipitation of metals such as iron so wet season impacts to the river are much reduced. Dry season impacts are also limited. Arsenic, barium, manganese, calcium, and magnesium all appear to be elevated in background samples suggesting that natural geochemistry has a large role in metals input to the river. In 2016 porewater sampling will target the biologically active porewater zone close to the mudline and will also include bioassay sampling to better determine potential impacts to river bottom dwelling organisms.
In the summer of 2016 an investigation of areas of the landfill cap with sparse vegetation was performed. There are several areas on the landfill where trees have struggled to grow for many years. It was hypothesized that these areas were subject to increased methane discharge and that methane venting might improve tree survival in selected areas. Excessive methane in the soil starves vegetation of oxygen and causes stunting or die-off of plants and trees. An investigation of the overall landfill soil cap thickness in 2005 found the average cap thickness was over 10 feet. The 2016 investigation found that soil cap thickness was much smaller (average of 3 feet) in areas where vegetation is sparse. It was concluded that methane venting in these areas would not be effective and that adding more soil was likely the only means to improve vegetation survival.
