Water sources across the Top End
Darwin, Palmerston and Katherine are on treated mains water. Wet-season turbidity events are managed at the plant, but premises-side hot-water sediment is common.
The dominant supply on remote and rural properties — wet-season rainfall floods catchments but the long dry-season stagnation is the bigger risk for annual testing.
Top End bores drawn from lateritic profiles run iron- and manganese-heavy. Katherine catchment bores need PFAS-specific consideration.
Some remote communities rely on managed dam or river-diversion supplies — infrastructure varies significantly.
Suburbs we test in
Darwin & Palmerston
Darwin, Palmerston, Humpty Doo, Howard Springs. Power and Water Corporation mains supply plus rural-residential tank properties on the fringe.
Katherine Region
Katherine, Tindal, Pine Creek. Nationally documented PFAS legacy zone near RAAF Base Tindal — testing needs a specialist referral in the flagged catchment.
Tiwi & Arnhem
Tiwi Islands, Wadeye, remote East Arnhem communities. Community-managed water supplies plus tanks — mail-out kits ship Territory-wide.
Physical, chemical, and microbial parameters analysed to ADWG.
Bookings within this region route to a nominated PWS Partner for follow-up quotes on any recommendations.
