EPA says, nationally, a fifth of tanks were a risk to human health.
54 per cent of domestic septic tanks in Kildare failed inspections last year.
The Environmental Protection Agency, in a national report issued today, says 23 per cent were a risk to human health or the environment.
Six local authority areas had failure rates of above 75 per cent, with 85 per cent below the required standard in Roscommon.
In Kildare, 34 septic tanks were inspected in 2019, and 39 last year.

Noel Byrne, from the EPA, says there were two main reasons for failures.
There are over half a million septic tanks & other domestic waste water treatment systems in Ireland. Over half of the 800 systems inspected in 2020 failed.
