Case History: In Situ Bioremedation - Oil Spill Recovery Pond.
Remediation Time: 10 Days
Subject: Oil Spill Detention Pond and Pump Island Area Maintenance
From: Seabourne Inc.
To: Consolidated Fast-Freight Inc.
1. After two consecutive oil and grease residual tests indicated a very high count, a determination was made to fully document a second trial test with SOLUTION 2000™ Colloidal Agent in an attempt to alleviate this situation. The allowable residual is 30ppm and the test showed amounts in excess of 50 PPM.
2. SOLUTION 2000™ had remedied a prior situation encountered in the Oil Detention Spill Detention Pond. In that instance the application of SOLUTION 2000™ resulted in a drop from several hundred PPM to 17ppm, which brought the pond into compliance with Water Quality Control Department of Natural Resources and Community Development Standards. It was noted that monthly tests are required for residual oil and grease and weekly tests are required for Ph.
3. The program as outlined, in consultation with Mr. William Roberts, the distributor of SOLUTION 2000™ Colloidal Agent, was the daily wash-down of the pump island and the retention area to the rear of the maintenance shop. The dilution was to be applied in a ratio or 40 parts water to 1 part of SOLUTION 2000™ 10X Colloidal Agent sprayed onto the concrete aprons of the outlined areas.
4. Implementation of the program was to begin on April 14. A fifty-five gallon drum of the agent was placed on the center pump island, along with a drum mounted, Dema Model 244BCDM in-line chemical injector.
Mr. Tom Miller and Mr. John Gilbert, of the Consolidated Terminal, were present for the demonstration. Mr. Miller was appointed by Mr. Gilbert to be responsible for the day-to-day operation of the program.
Under the direction of Mr. Roberts, Mr. Miller applied the colloidal agent on the concrete aprons in the affected areas. The colloidal agent was allowed to remain and penetrate the concrete for 30 minutes. The colloidal agent was then rinsed with clear water at about 40 PSI. The areas were flushed and the action resulted in the heavy buildup of oil and grease being broken down and flushed into the drains in these areas. This discharge goes into an oil separator and then into the detention pond.
The immediate results of the colloidal agent were very good and the daily use of SOLUTION 2000™ Colloidal Agent was continued through April 18. Daily inspections of the results were conducted and within this period, the affected areas became clear, and odor free.
A second week of the program was recommended and the continuing good results of the area spray-down justified its continuance until such time as the detention pond testing results became positive.
Testing of the pond revealed a heavier build-up of oil and grease residual. It was discovered that a major cause of this build-up was the steam cleaning of vehicle engines and parts in the containment area to the rear of the maintenance shop. A recommendation was made that this activity by the shop be discontinued. The design of the containment system had not been based upon handling this situation. Action was taken by the Terminal Manager to end this activity by the maintenance shop.
An additional factor contributing to the heavy build-up was the continuing drought suffered by the area. We were in the midst of the worst drought in 100 years. The amount of water entering the pond was being absorbed by the earthen pond and evaporation and was causing an increased build-up of the residuals.
5. The determination to do a major pond clean-up was made. The Distributor, Mr. Miller, was consulted and a program was instituted under his direction.
In April, testing of the pond effluent resulted in readings in excess of 1,050 PPM and in May was test results yielded readings of 1,455 PPM. On June 4 a pumper truck from the Volunteer Fire Department, operated by the Chief, was brought to the pond. Captain Johnson and Chief Blair, of the Volunteer Fire Department was on the scene to tape record the demonstration. These gentlemen volunteered to witness and participate in the program. Their interest was in the application and results of the use of SOLUTION 2000™ Colloidal Agent for possible use by their respective departments.
Test samples of the effluent waters were made at the Influent 8” CIP into the pond and the 15”RCP effluent line from the pond. These tests were analyzed by Baxter Laboratories, Inc. and are noted as Sample #1 and #2 on their written report dated June 18, and attached as a part or this report. Sample #1 was 58 PPM and Sample #2 was 65 PPM The pond was flooded with 850 gallons of water mixed with 25 gallons of SOLUTION 2000™ 10X Colloidal Agent, (mixture ratio 35 : 1). The pumper truck was operating at 200 PSI at the fog nozzle. The accompanying videotape gives the operationa1 procedure and application times.
The attached “Analysis Sheets” Baxter Laboratories Inc. and Ronson Laboratories authenticate the positive results of the program demonstration,
A. Test results:
(1) Day one: Test #2 Baxter 65 PPM / 30 PPM
(2) Day three: Test #3 Baxter 28 PPM / 30 PPM (compliance)
(3) Day five: Test #4 Baxter 26 PPM / 30 PPM (compliance)
(4) Day seven: Test #6 Ronson 22 PPM / 30 PPM (compliance)
(5) Day ten: Test #5 Baxter 6 PPM / 30 PPM (compliance)
B. The required time of the SOLUTION 2000™ Colloidal Agent to completely dissipate is seven (7) days.
C. Day eight the pond was flooded with 5,000 gallons clear water.
D. Day 10: The pond was drained. Test sample #5 Baxter was taken.
E. Demonstration test terminated. In compliance with DNRCD Water Quality Division.
6. Recommendations: Water
A. Based upon the successful results, it is recommended that the daily spray down of the pump island and fuel tank containment area with SOLUTION 2000™ be implemented as a permanent program. With the program in place, adequate quantities of SOLUTION 2000™ will be introduced to the Detention Pond. Treatment of the Detention Pond will no longer be required, as the oil will be introduced to the Detention Pond with the molecules of oil separated and held in Colloidal Suspension in the water. This will promote rapid and continual biodegradation of the oil by naturally occurring bacteria so that a build-up will not occur.
(1.) This program will insure the continued compliance with the requirements of the DNRCD Water Quality Control monthly testing program.
(2.) The program has reduced the notable presence of diesel fuel odors around the pump islands thus providing safer working conditions for those who are working continually within the area. It has also removed the continued possibility of the workers and drivers slipping and falling on the concrete surfaces.
B. Based upon the results of the detention pond clean up, we now have a proven program for handling the residual buildup of oil and grease, when conditions necessitate such action.
C. The terminal personnel and management have seen the results of the trial programs and they seem to feel that these are viable and needed programs.
D. Terminal Management is being furnished a copy of this report. They have been asked to submit any comments or recommendations they may have.
Yours very truly,
Note: SOLUTION 2000™ breaks down the oil and holds each molecule of oil separately, in colloidal suspension, throughout the liquid. This leaves individual molecules of oil open to simultaneous attack by naturally occurring bacteria. This process is far superior to adding enzymes, which would have to eat their way through a slick floating on the water. Holding the molecules of oil in colloidal suspension provides a three dimensional, rather than a two dimensional natural bacterial attack.
