Environmental monitoring is undertaken to determine the effects on the environment of activities such as land development, farming and industrial activity. Subdivision, construction and earthworks, stormwater, discharges from wastewater treatment plants and farm irrigation can all affect water quality of lakes and rivers.

Trident Monitoring Services Ltd can monitor flow, temperature, dissolved oxygen and water quality in lakes, rivers or at point source. AEEs (Assessments of Environmental Effects) or provision of quality data for engineering consultants are a specialty.

Completed environmental monitoring jobs include:

• Long term odour monitoring of a composting facility
• Water quality & volume assessment for alternative water supply
• Aggressive water testing
• Waikato River temperature survey

A variety of farming and industrial activities can result in chemical contamination of soil, air and water. When hazardous substances are found at a level significantly higher than background levels, a site is considered to be contaminated. Pesticides, hydrocarbons, metals and other chemicals can contaminate soil and groundwater for long periods after the site is no longer used for the activity which caused the contamination.

Trident Monitoring Services Ltd consultants can devise a cost-effective but robust sampling programme, report results in a contestible manner, and recommend rehabilitation strategies.
