Manawatu District mayor Helen Worboys said she'd been visiting property owners who had expressed their own concerns.
"In addition to water use, residents have concerns about the future of their farms, and are asking for further testing of the soil. Those on untested neighbouring properties are also concerned."
She said she was confident all of these issues would be part of the investigation.
Horizons has also confirmed they will begin their own formal investigation, which could result in legal action.
A joint statement by the New Zealand Defence Force and Ministry for the Environment said their staff had also visited affected properties. A spokesperson said each site would be affected differently and they had to deal with these on an individual basis.
"People have different questions and concerns, again depending on their circumstances.
The advice provided is tailored to those individual circumstances, so may vary from person to person."
They were now working closely with regional councils to expand communication to members of the community who were not directly affected but may have concerns.
"People have raised a variety of potential issues with us and the Ministry of Health and Ministry for Primary Industries have been addressing those directly with them, including during visits to their homes. We have advised landowners and occupiers that if they have further questions they can contact the helplines."
The long-term impact of this contamination was still being assessed but would be a key consideration. Scope testing may also be widened however those details were still being finalised.
