Harvest Scientific Services has the expertise to plan and execute a range of environmental monitoring functions which are applicable across a large range of industries. This often entails routine dust and water monitoring as required by the approval conditions issued by Federal, State or Local Government agencies for a range of activities. Parameters such as the ash content, combustible matter, total insoluble matter and total suspended particulates in airborne dust and the pH, total suspended solids and conductivity of water are monitored as required.
As part of the service, Harvest Scientific Services provides interpretative commentary with respect to operational compliance of the activity being monitored.
In addition, the Firm conducts a number of soil validation and contamination assessments at the request of clients.
For those aspects that require specialised monitoring such as noise and air quality, the Firm, through its extensive network of kindred associations, has the capability to employ a range of specialist consultants who provide these services.
In conjunction, Harvest Scientific Services has extensive experience in the field of soil and water management and the preparation of Erosion and Sediment Control Plans (ESCP’s). An ESCP is necessary in most developments to mitigate against the potential of water action (including surface and groundwater) to impact the development proposal and its immediate surrounds both during the construction and operational phase. In addition, the plan is required to spell out what measures would need to be implemented to avoid, minimise, mitigate, offset, manage and/or monitor these potential impacts.
In general terms, most ESCP’s reference a number of key publications, including:
- Managing Urban Stormwater, Soils and Construction (the “Blue Book”), 3rd Edition. NSW Department of Housing 1998.
The general objectives of ESCP’s are set out below.
- To minimise erosion and sedimentation from all active and rehabilitated areas, thereby minimising sediment ingress into surrounding surface waters;
- To ensure the segregation of “dirty” water from “clean” water, and maximise the retention time of “dirty” water such that any discharge from a development site meets the relevant water-quality limits, including limits contained in relevant guidelines and any limits imposed by specific project approvals. “Dirty” water is defined as surface runoff from disturbed catchments (e.g. active areas of disturbance, sand and soil stockpiles and rehabilitated areas (until stabilised)). “Clean” water is defined as surface runoff from catchments that are undisturbed or relatively undisturbed by project-related activities and rehabilitated catchments;
- To minimise the volume of water discharged from the development site but, should the discharge of water prove necessary, ensure sufficient settlement time is provided prior to discharge, such that suspended sediment within the receiving waters meets the above objectives;
- To ensure sustainable long-term surface water features are established following rehabilitation of a development site, including implementation of an effective revegetation and maintenance program; and
- To monitor the effectiveness of surface water and sediment controls and to ensure all relevant surface-water quality criteria are met.
Harvest Scientific Services can assist developers in the design and implementation of an ESCP to the satisfaction of consent authorities such as Councils and State Government regulatory authorities.
