Appendix B: Procedures for Evaluation of Innovative Technologies
Steps, Specific Information
This protocol describes the steps involved and information required for the establishment of an innovative system whose purpose is to provide monitoring and performance data. If systems are to be used for collection of data, sufficient background information is required.
The monitoring specified would not be feasible or necessary on every "experimental" system. However, all experimental systems should be designed and built to allow easy access for monitoring of the parameters specified. Homeowners or other on-site system owners should agree to allow health departments and other interested agencies reasonable access to the property for sampling and system inspection with prior notice.
In order to implement all phases of the monitoring program, a critical component to the assessment of system performance, a method of funding for monitoring of experimental systems may be necessary. Most homeowners will be unable to participate in such a venture if the individual homeowner is expected to bear the cost of such items as monitoring ports, flow meters, equipment and sampling.
Steps: (For detailed requirements, see "specific information")
Contact county and state health departments informing them of your intent.
Obtain written permission from property owner.
Upon approval, have a soils examination performed by an individual certified by either ARCPACS or the Indiana Soil Classifiers Association as a soil scientist or soil classifier. (A list of certified individuals is available from the state health department.)
Obtain personnel, site and location information as specified below.
Select system appropriate for site.
Prepare detailed system design.
Prepare proposed monitoring and maintenance programs.
Obtain approval/permit for construction from state and then county health departments.
Construct system undergoing usual health department procedures with any additional requirements as required by the permit for the experimental system. Construction inspections must be conducted by state and/or local health department officials. File copies of system plans as installed in county and state health departments. There should not be any significant variation from original plans without new approval from the health department prior to proceeding with construction.
Perform monitoring and maintenance. For each action taken, record in a log:
Who performed the action
What was done
Why was the action performed
Results or effects
Copies of the monitoring log and sample results shall be forwarded to the agencies within the time frame specified in the project approval.
At end of monitoring period, have state and/or county sanitarian perform system and site inspection.
Arrange meeting with contractor and/or engineering firm, property owner, and representatives from state and county health departments to discuss data and system approval.
Land owner name, "911 address" (including county), phones, fax, email
Participating Health Department name, address, phones, fax, email
Name of sanitarians and other involved personnel
Name of person making contact, relation to project, phones, fax, email
Date of contact with project
Lot survey map, property boundaries
Lot diagram to scale with 2 ft. or other appropriate contour lines
Home or other existing buildings
Existing wastewater disposal system
New or existing well (location, type, depth, water level); Include wells on adjacent properties which may be within required separation distances.
Driveways, roads, paths, sidewalks
Underground electric, phone, gas and other utilities
Outbuildings, swimming pools, and other constructed features
Surface water (streams, ditches, lakes) and nearby tile drainage
All structures on adjacent properties which may affect system performance by impeding surface or subsurface flow away from the system site
Present Vegetation. If in crops, list crops for last three years and tillage methods used.
If system is a repair or replacement, obtain, if possible, plans for old system.
Evaluate reasons for failure
Why the repair or new system
Name of soil scientist, address, phones, fax, email
Position in landscape
Slope, shape of slope, slope aspect
Profile descriptions, reports prepared for site
Minimum of 5 probes should be made, one in each of the four corners of the proposed absorption field site, and one in the middle. All profile descriptions must be recorded and submitted. Additional borings or a pit dug with a backhoe may be required at the discretion of the permitting agency.
Any record of previous examinations
Estimates of height and duration of seasonal high water table
Any information available on geologic conditions; depth to water table if site has an unconfined aquifer.
System Design Selection
Reasons for selection
Engineer or contractor, name, address, phones, fax, email
Plans for monitoring program
Use timers if applicable
Sampling frequency and parameters should be determined and recorded as a part of the permit issuance
Sampling and analysis should occur for a minimum of 2 years. Sampling should be frequent enough to assess performance in light of seasonal variations (not more than once a month). Frequency will depend upon the nature of the system. Samples should be analyzed from:
Septic tank effluent (if applicable)
Treatment(s) effluent (if applicable)
Before (upslope) the system (This provides baseline data.)
Downslope or downgradient of the system (A minimum of 2 groundwater wells 10 feet from system edge.)
Between trenches (At a midpoint between the trenches, near the center and/or downslope end of the system.)
In trenches or absorption bed(s) (This may be limited to water level only.)
Specific depth and number of observation wells will depend upon site characteristics. Monitoring of addition observation wells in excess of those specified above may be limited to water depth.
Parameters may include: (report concentrations in mg/L or CFU/100 mL)
B.O.D. (Five day biological oxygen demand)
T.S.S. (Total suspended solids)
Total Fecal Coliforms
NH3 (Usually analyzed in combination with NH4.)
TKN (total kjeldahl nitrogen) or total nitrogen
NO3 (Usually analyzed in combination with NO2.)
Cl- (If applicable)
Water level in observation pipes
Influent and effluent wastewater flow from all treatment components
Sampling methodology (range of detection and accuracy)
Name, location, and phone number of certified lab performing the analysis
Plans for maintenance
Estimation of maintenance (type, frequency, cost)
Property owner responsibilities
How compliance will be monitored
Contractor(s) name, address, phone, fax, email
Dates of construction
Variations from original plans, unusual conditions, other pertinent observations; a set of "as built" plans must be provided
