1.1 Purpose

The purpose of this Phase II Environmental Site Assessment (ESA) was to investigate the potential impacts of Recognized Environmental Conditions (RECs) associated with the subject property, which were identified during the Phase I ESA. This report documents the findings, opinions, and conclusions of the Phase I ESA. This Phase II ESA was performed in accordance with American Society of Testing and Materials (ASTM) Standard E 1903‐11.

1.2 Scope

The purpose of this Phase II ESA was to investigate potential soil contamination posed by the RECs identified during the Phase I ESA.

This Phase II ESA was conducted in general accordance with the ASTM Standard Practice E1903‐11, consistent with a level of care and skill ordinarily practiced by the environmental consulting professional currently providing similar services under similar circumstances. Any significant additions, deletions, or exceptions to ASTM Standard Practice E1903‐11 are noted in the corresponding sections of this report.

1.3 Findings and Conclusions Summary

Previously, Booz Allen performed a Phase I Environmental Site Assessment (Phase I ESA) of the subject property in conformance with the scope and limitations of ASTM Standard Practice for Environmental Site Assessments E1527‐13. Booz Allen identified the following RECs that may affect suitability of the subject property for its intended uses:

The “Milk House” on the north side of Building 3006 contained several bottles of regulated pesticides/herbicides such as Amine 4 (2,4‐D) weed killer and a jug of Chlordane. The improper storage of regulated substances has resulted in staining along the concrete floor near a floor drain found within the Milk House. Additionally, a septic system with a drain field is located on the subject property; although the exact location of the drain field was unknown at the time of the Phase I ESA.

The potential for contaminants to migrate from Building 3006’s drains and deposit contaminants in soil presented a REC for the subject property.

The “Shed” on the south side of Building 3006 contained several bottles and drums of petroleum products, and staining was visible on the wooden floor of the building. It was believed that a crawlspace underlies the building with exposed soil directly underneath the floor. The potential for contaminants to leach from Building 3006’s floors to the underlying soil presented a REC for the subject property.

Booz Allen conducted a Phase II ESA to characterize the site on November 7, 2018. Based on the findings of the Phase I ESA, four wipe samples and seven surface soil samples were collected and analyzed for Volatile Organic Compounds (VOCs), Semi‐Volatile Organic Compounds (SVOCs), Pesticides, and Herbicides. Wipe samples were collected from the visibly‐stained areas in the two outbuildings and soil samples were collected from around the exterior of the outbuildings, and along a drain pipe leading offsite toward Aldine Western Road from the Milk House. Booz Allen utilized the services of Ground Penetrating Radar Systems (GPRS) to provide subsurface mapping of utilities and to locate the septic system and drain field.

Analysis of the two soil samples collected from beneath the floor of the Shed (3006‐SS‐1 and 3006‐SS‐2) yielded results indicative of a release of Dieldrin, a pesticide, to surface soil. These results exceeded the Texas Commission on Environmental Quality’s (TCEQ’s) Protective Concentration Levels (PCLs) for residential soil. Sample 3006‐SS‐2 also exceeded the commercial PCL for Dieldrin.

4‐Chlorophenyl phenyl ether, a SVOC, was detected above the residential PCL in all soil samples collected, and above commercial PCLs in four of the samples (3006‐SS‐3, 3006‐SS‐4, 3006‐SS‐5, and 3006‐SS‐6). 4‐Bromophenyl phenyl ether was detected above the residential PCL at four sample locations (3006‐SS‐3, 3006‐SS‐4, 3006‐SS‐5, and 3006‐SS‐6), and above the commercial PCL in Sample 3006‐SS‐6. Hexachlorobenzene was also detected above the residential PCL at four sample locations (3006‐SS‐3, 3006‐SS‐4, 3006‐SS‐ 5, and 3006‐SS‐6).

The analytical data obtained during the Phase II ESA indicate that contamination exceeds Texas Commission on Environmental Quality’s soil cleanup levels in several locations, primarily for pesticides and SVOCs. Based on the Phase II ESA analytical results, Booz Allen identified the following impacts at the subject property:

The results of the Phase II ESA confirmed that surface soils on the subject site have been impacted by Pesticides and SVOCs.

Subsurface investigation with a GPR discovered that the floor drain in the Milk House leads off the subject site to a presumed outfall in the roadside ditch. There is a high likelihood that this drain pipe provided a pathway for contaminants to migrate offsite and impact surface water. A ditch was observed along the south side of Aldine Western Road, and GPR indicated that the floor drain in Building 3006 is connected to a drain pipe which appears to discharge in the direction of this ditch. The nearest surface water feature (Greens Bayou) is located approximately 3,000 feet northwest of the subject site.

It is the opinion of Booz Allen Hamilton that additional investigation (e.g., Expanded Phase II ESA) of the horizontal and vertical, nature and extent of contamination identified in the Phase II ESA is warranted for the subject site.

2.2 Location and Legal Description

The subject property includes two outbuildings, collectively known as Building 3006, located in Houston, Texas towards the northeastern boundary of the VA’s Houston National Cemetery property. The subject property’s is located at 1621 Aldine Western Road and adjacent areas encompass approximately 183 acres of agricultural land. The subject property is located at approximately 29.935224° north latitude and 95.440313° west longitude. The subject property is owned by the VA but is leased for agricultural purposes to Mr. Wayne Benfer. The VA plans to demolish the on‐site buildings.

Concourse provided Booz Allen with due diligence information regarding the on‐site buildings, including their total gross square feet (GSF) and build years. Although the build year of the buildings were listed as 1963, Booz Allen’s review of historical aerial photographs during the Phase I ESA indicates that the buildings were constructed sometime between approximately 1944 and 1953, when the buildings are first observed on the subject property.

2.3 Surrounding Area General Characteristics

The area surrounding the subject property is owned by the VA and is described as the “Houston National Cemetery”. The subject site is located in a developed residential, commercial, and light industrial area within the city of Houston, Texas. Areas to the east of the site appear to be topographically downgradient from the subject property, and areas to the north of the site appear to be topographically upgradient from the site.

The Houston National Cemetery is west of the subject property and includes an administration building, burial sites, and paved access roads. Adjoining the subject property to the immediate east, south, and west is approximately 183 acres of agricultural land associated with previous cattle grazing. Aldine Western Road bounds the subject property to the north.

The local area consists primarily of single‐family residences, commercial buildings, and industrial buildings and warehouses.

Adjoining Properties

North Aldine Western Road borders the subject property to the north. A horse pasture and associated stables adjoins the site to the north. Farther north is the Sam Houston Tollway.

Northeast Across Aldine Western Road is Petroleum Oil Tools Inc. (1620 Aldine Western Road). The facility includes an industrial warehouse and adjacent administration building, a retention pond, and an aboveground storage tank (AST). The intersection of Sharmon Road and Aldine Western Road is located farther northeast of the site.

(1900 Aldine Western Road), Late Model Engines (1930 Aldine Western Road), Texas Honing (2000 Aldine Western Road), and Crescent Directional Drilling (2040 Aldine Western Road).

2.4 Current Use of the Subject Property

The subject property includes a residential home and two outbuildings previously used for agricultural purposes, as described in Section 2.2. The buildings were constructed in 1953 and are currently vacant.

An administration building, burial grounds, and paved access roads are located on The Houston National Cemetery property west of the subject property. The subject property is located on outleased land from the Houston National Cemetery.

2.5 Description of Property Improvements

2.5.1 BUILDINGS

The two out buildings which collectively are known as Building 3006 have presumed transite siding and tin roofs. Building 3006 is currently unused but has historically been leased for agricultural purposes as part of a dairy farm. The interior of the southern portion of Building 3006, the “Shed” includes open space with exposed‐beam wood‐paneled walls and wood floors. The northern half of Building 3006, the “Milk House”, is comprised of an open entrance space, a back office, a small bathroom, a water heater, and a floor drain. The interior of the northern portion of Building 3006 includes concrete floor and concrete block walls. At the time of the site reconnaissance, several bottles and buckets of oil, gas, paint, weed killer, lubricant, fertilizer, grease, and hydraulic fluid were observed, including a box of Amine 4 (2,4‐D) weed killer, a five‐gallon bucket of regal oil, a bucket of lithium grease, and a jug of 72% Chlordane. During the site reconnaissance a distinct pesticide/herbicide odor was noted. Evidence of floor staining from the abovementioned containers was observed throughout the interior of Building 3006 and near the floor drains in the northern half of the building.

2.5.2 UTILITIES

The subject property is supplied with electricity by CenterPoint Energy and water utilities by Aldine Municipal. No gas is supplied to the subject property. No sewer connection is on the subject property, and a septic system is reportedly in place with a drain field located on the subject property, although its exact location is unknown.

2.5.3 ROADS/PARKING

An access road off Aldine Western Road is the only paved access to the subject property. The subject site is bound on the east, south, and west by grassed fields previously used for agricultural purposes. Dirt paths lead from the subject property to the south but have no direct access to any other paved roads.

2.5.4 CURRENT USES OF ADJOINING PROPERTIES

The subject property is located on the northern boundary of the Houston National Cemetery and is bordered to the north by Aldine Western Road. The site is adjoined on the east, south, and west by open fields previously used for agricultural purposes. Farther west is the Houston National Cemetery’s main facility including an administration office, burial grounds, and paved access roads. The subject site is located in a residential, commercial, and light industrial area of Houston, Texas.

2.6 Physical Setting Sources

2.6.1 TOPOGRAPHY

Based on a review of the USGS Aldine 7.5‐minute topographic map dated 2013, the elevation at the subject property is approximately 93 feet above sea level. The topographic profile in the vicinity of the site is generally towards the east. Small ponds are located west and southwest of the subject site on the Houston National Cemetery; many of which are manmade. The nearest surface body of water is the Greens Bayou stream, which is approximately 0.6 miles northwest of the subject site and flows eastward. Greens Bayou is a part of the Greens Bayou watershed and covers an area of roughly 212 square miles including the northern portion of the city of Houston.

Building 3006 sits at an elevation of approximately 94 feet above sea level. Surrounding areas to the south and west are predominantly flat. Areas north of the site are presumed to be topographically upgradient from the subject property. Surface water from Buildings 2501 and 3006 is expected to flow to the east towards Greens Bayou.

2.6.2 GEOLOGY

Based on the review of the United States Geological Survey’s (USGS) Texas geologic map, the subject site is underlain by Quaternary Holocene and Quaternary Pleistocene. Quaternary Holocene and Pleistocene are comprised of an upper part clay, silt, sand, and very minor siliceous gravel. A physical evaluation of geologic conditions on or in vicinity of the subject property was not included in the scope of this Phase I ESA.

2.6.3 GROUNDWATER

Based on a review of the USGS Aldine 7.5‐minute topographic map dated 2013, the subject property is situated topographically crossgradient from the surrounding properties to the south and west. The topographic profile in the vicinity of the site is generally towards the east. The Greens Bayou stream is northwest of the subject site and flows eastward.

2.6.4 HISTORICAL SUMMARY

The subject property appeared to have been developed since 1953, when the current on‐site buildings were constructed. The Houston National Cemetery began development west of the subject site the following decade and has since continued development throughout at least 2012 when additional ponds and fixtures were constructed. The adjacent areas to the south and east of the subject property have remained undeveloped. No significant changes to the site were identified from 2016 (aerial photograph) until the time of the site reconnaissance. No obvious indications of on‐site RECs were identified during the historical review of the site.

Areas surrounding the subject property appear to have been primarily developed since at least 1973 when residential construction began to expand south of the subject site. Areas more directly surrounding the subject property developed throughout the 1970s through the early 2000s, where aerial photographs show the surrounding properties closely resembling that observed at the time of site reconnaissance. No environmentally significant conditions were observed within 1 mile of the subject property during the historical review.

3.1 Methodology

On November 7, 2018, Mr. Scott Bolch of Booz Allen Hamilton and Mr. Marshall Contino of Concourse Federal Group conducted a site investigation of the subject property. See Section 8 to review the site photographs. The purpose of the site inspection was to identify site use characteristics and to investigate potential soil contamination posed by the RECs identified during the Phase I ESA.

There were no limiting conditions present on the subject property at the time of the site visit.

The weather at the time of the site inspection was sunny with clear skies, and the temperature was approximately 80 degrees Fahrenheit. Mr. Scott Weber escorted Mr. Bolch and Mr. Contino on a walking reconnaissance of the subject property.

3.2 Sampling and Screening Methods

The objective of the soil sampling was to investigate the potential extent of contamination at the subject site. To investigate the potential impact to soil from the RECs identified during the Phase I ESA, seven surface soil samples (0” – 6” below ground surface) were obtained using a stainless‐steel hand auger. Two of these samples were collected from beneath the visibly‐stained floor of the Shed. Wipe samples were collected to investigate the potential for target analytes in the visibly stained areas. Four wipe samples were collected from the stained surfaces by wiping a 4‐inch by 4‐inch area with pre‐preserved gauze pads. These samples were analyzed using the same parameters as the soil sampling. Please see Section 9 to review the site maps and sampling locations for this facility.

The following analyses were conducted for the soil and wipe samples:

Volatile Organic Compounds (EPA Method 8260B), Semi‐Volatile Organic Compounds (EPA Method 8270C), Pesticides (EPA Method 8081A), and Herbicides (method 8151)

After sample collection, a completed label was attached to each sample container and covered with packing tape. The sample containers were wrapped in bubble wrap and then placed in plastic zip‐top bags. All samples were placed in a plastic lined ice chest with double‐bagged ice. The chain‐of‐custody forms were taped on the inside of the cooler lids, and the coolers were secured with custody seals. The samples were delivered the same day to the Test America Laboratory in Houston. All samples were received by the laboratory in good condition and within 4°C ± 2°C. CoC forms are included in Attachment C.

Analytical results were compared to the applicable TCEQ residential soil PCLs, as shown in Attachment C.

4 R E S U L T S

4.1 Site Conditions

4.1.1 SEWAGE

Previously, Mr. Scott Weber identified a presumed septic tank adjacent to the south side of Building 2501. During the Phase II ESA, the Services of GPRS were utilized in an attempt trace the drain pipe emanating from the floor drain in the Milk House, and to detect the septic system and drain field. Utilizing a Ground‐Penetrating Radar (GPR) system, a septic field was identified south of Building 2501. A septic tank was observed adjacent to the south side of Building 2501.

4.1.2 FLOOR DRAINS

A floor drain was observed in the Milk House. GPR was utilized to trace the discharge drain pipe emanating from the floor drain north to the property line, where it presumably drains into a ditch along Aldine Western Road. The outfall of this drain pipe was not observed due to thick brush.

4.1.3 DRINKING WATER

Drinking water is available at the site but is not currently utilized because the site is vacant.

4.1.4 CHEMICAL STORAGE AND HAZARD COMMUNICATION

Bottles and cans of petroleum products were observed situated on the wooden floor of the shed. Multiple bottles of 2,4‐D herbicides were observed situated on the floor of the Milk House, and a bottle of chlordane pesticide was observed situated in a cabinet. Wipe samples were collected from the floors around the bottles.

4.1.5 STAINING OR RELEASES

Two stained areas were observed at the subject site. One stained area was observed on the wooden floorboards of the shed, surrounded by bottles and cans of petroleum products. The other stained area was observed around a floor drain in the Milk House.

Multiple bottles of 2,4‐D herbicides were observed situated on the floor, and a bottle of chlordane pesticide was observed situated in a cabinet. Wipe samples were collected from the stained areas.

4.1.6 PESTICIDES

Based on the findings of the Phase I ESA, a bottle of chlordane pesticide was observed situated on the floor of the Milk House. It was inferred that the chlordane was applied to the subject site. Additionally, multiple bottles of 2,4‐D herbicide were observed situated on the floor of the Milk House. Visual observations in this outbuilding indicated that product mixing had likely taken place around a floor drain. It was also inferred that the 2,4‐D pesticides were applied to the subject site. Pesticide application for surrounding properties is unknown.

Booz Allen field personnel recorded all field activities in field logbooks. Photographs captured during the field investigation were consolidated into a photographic log and copies are presented in Section 8.

4.2 Analytical Results

On November 21, 2018, Booz Allen received the analytical results from the groundwater sampling event. After a comparison with the TDEQ PCLs (updated April 2018), most sample locations were found to exceed the screening levels for several analytes.

Two soil samples were collected from beneath the floor of the Shed and five soil samples were collected from the exterior of Building 3006. Two of these exterior samples were collected around the discovered drain pipe on the north side of the subject site.

Analysis of the two soil samples collected from beneath the floor of the Shed (3006‐SS‐1 and 3006‐SS‐2) yielded results indicative of a release of Dieldrin, a pesticide, to surface soil. Dieldrin was commonly used from the 1950s until 1970 but was discontinued by the manufacturer in 1987. Dieldrin may enter the environment from spills or leaks from containers, or during agricultural uses eradicate pests and termites. These results exceeded the TCEQ’s PCL for residential soil. Sample 3006‐SS‐2 also exceeded the commercial PCL for Dieldrin.

4‐Chlorophenyl phenyl ether, a SVOC, was detected above the residential PCL in all soil samples collected, and above commercial PCLs in four of the samples (3006‐SS‐3, 3006‐SS‐4, 3006‐SS‐5, and 3006‐SS‐6). 4‐Chlorophenyl phenyl ether is used as a dielectric fluid. 4‐Bromophenyl phenyl ether was detected above the residential PCL at four sample locations (3006‐SS‐3, 3006‐SS‐4, 3006‐SS‐ 5, and 3006‐SS‐6), and above the commercial PCL in Sample 3006‐SS‐6. 4‐Bromophenyl phenyl ether is primarily used for research purposes. In the past it was used as a flame retardant. Hexachlorobenzene was also detected above the residential PCL at four sample locations (3006‐SS‐3, 3006‐SS‐4, 3006‐SS‐5, 3006‐SS‐6). Hexachlorobenzene was used as a pesticide until 1965 and is also a byproduct during the manufacture of other chemicals and pesticides. An analytical data table is included in Section 10.

Analysis of the wipe samples collected from the visibly stained areas in the Shed and the Milk House indicated no significant surface contamination. Bis(2‐ethylhexyl) phthalate (DEHP), an SVOC, was detected above the reporting limit at sample locations 3006‐W‐1 and 3006‐W‐2. DEHP is a common laboratory contaminant and is also used as a plasticizer and found in many plastic products.

Because DEHP is a common laboratory contaminant and was not detected in soil at concentrations exceeding the residential PCL, it is not believed to have presented an impact to the subject site.

5 C O N C L U S I O N S A N D R E C O M M E N D A T I O N S Based on the Phase II ESA analytical results, Booz Allen identified the following impacts at the subject property:

• The results of the Phase II ESA confirmed that surface soils on the subject site have been impacted by Pesticides and SVOCs. Based on these results, contaminated soils were found throughout the site and the horizontal and vertical extent of contamination is unknown.

• Subsurface investigation with a GPR discovered that the floor drain in the Milk House leads off the subject site to a presumed outfall in the roadside ditch. There is a high likelihood that this drain pipe provided a pathway for contaminants to migrate offsite and impact surface water. A ditch was observed along the south side of Aldine Western Road, and GPR indicated that the floor drain in Building 3006 is connected to a drain pipe which appears to discharge in the direction of this ditch. The nearest surface water feature (Greens Bayou) is located approximately 3,000 feet northwest of the subject site.

It is the opinion of Booz Allen Hamilton that additional investigation (e.g., Expanded Phase II ESA) of the horizontal and vertical, nature and extent of contamination identified in the Phase II ESA is warranted for the subject site. Additional historical use information should be obtained for the subject property, and additional sampling should be conducted to characterize the extent of contamination at the subject property.

6 D E V I A T I O N S This following deviations were noted during this Phase II ESA:

• Sample numbers were incorrectly designated with the building number as “2501” instead of “3006”. This deviation has no impact on the findings of this Phase II ESA. The sample numbers were corrected in the final laboratory report.

• Samples were planned for collection around the septic system. However, due to the discovery of the drain pipe leading offsite from the Milk House, and that the septic system is not connected to Building 3006, this deviation has no impact on the findings of this Phase II ESA.

Comments

This report was revised updating the sample IDs at the request of the client on December 4, 2018.

Receipt The samples were received on 11/7/2018 1:13 PM; the samples arrived in good condition, properly preserved and, where required, on ice.

The temperature of the cooler at receipt was 6.3º C.

GC/MS VOA

Method(s) 8260B: The continuing calibration verification (CCV) associated with batch 600-252426 recovered above the upper control limit for 2-Butanone (MEK). The samples associated with this CCV were non-detects for the affected analytes; therefore, the data have been reported.

Method(s) 8260B: The RPD of the laboratory control sample (LCS) and laboratory control sample duplicate (LCSD) for batch preparation batch 600-252424 and analytical batch 600-252426 recovered outside control limits for the following analytes:

1,1,2-Trichloro-1,2,2-trifluoroethane, 1,1-Dichloroethene, Carbon disulfide, and Cyclohexane

Method(s) 8260B: The following samples were diluted due to the nature of the sample matrix: 2501-W-1 (600-175884-1), 2501-W-2

(600-175884-2), 2501-W-3 (600-175884-3) and 2501-W-4 (600-175884-4). Elevated reporting limits (RLs) are provided.

Method(s) 8260B: Sample was prepped within the 14 day holding time for 8260B_H methods. PM incorrectly used wrong method code which requires samples to be prepped within 48 hours.

2501-W-1 (600-175884-1), 2501-W-2 (600-175884-2), 2501-W-3 (600-175884-3) and 2501-W-4 (600-175884-4)

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

GC/MS Semi VOA

Method(s) 8270C: Surrogate recovery for the following samples were outside control limits: 2501-W-1 (600-175884-1), 2501-W-2 (600-175884-2), 2501-W-3 (600-175884-3) and 2501-W-4 (600-175884-4). Evidence of matrix interference is present; therefore, re-extraction and/or re-analysis was not performed.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

GC Semi VOA

Method(s) 8081A: Since Methoxychlor RL was so high, dilution was not needed.

2501-W-1 (600-175884-1)

Method(s) 8151A: The continuing calibration verification (CCV) associated with batch 600-251927 recovered above the upper control limit for 2,4,5-TP(50.8%). The samples associated with this CCV were non-detects for the affected analytes; therefore, the data have been reported.

Method(s) 8151A: The continuing calibration verification (CCV) associated with batch 600-251927 recovered above the upper control limit for 2,4-DB(30.5%),Dinoseb(23.1%), and 2,4,5-TP(18.6%). The samples associated with this CCV were non-detects for the affected analytes; therefore, the data have been reported.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Organic Prep

Method(s) 3580A: The following samples required a Florisil clean-up, via EPA Method 3620B, to reduce matrix interferences: 2501-W-1 (600-175884-1), 2501-W-2 (600-175884-2), 2501-W-3 (600-175884-3) and 2501-W-4 (600-175884-4).
