Piha R&R has been sampling the Piha Lagoon for analysis by the Auckland Council’s Laboratory (Aqualab), at it’s own expense, for several months and before Council recommenced testing in the first week of November.
Results show clearly that the recent flushing of the lagoon by nature has resulted in a clean Piha Lagoon with all readings for both Bacteria (Ecoli) and chemicals (Phosphates and Nitrates) being significantly BELOW the safe swimming recommend levels set by Council. This contrast with unsafe levels recorded before the flushing.
Therefore it is puzzling that after three years of “unsafe” test results, Council has suddenly seen fit to not publish the latest results, but post on their website “Permanent Health Warning – Unsafe” and post a sign to that effect on the Eel Bridge !! See Council website HERE and below.
|North Piha Lagoon||Permanent health warning||Unsafe|
|Piha Lagoon||Permanent health warning||Unsafe|
|Piha North Beach||Thursday 03 November||<10 Safe|
|Piha South Beach||Thursday 03 November||<10 Safe|
Lagoon Flushing posting from R&R website in October (Below)
The lagoon has finally washed out naturally in that heavy rain we had over last weekend! First time for about 3- 4 years. It will be intereting to note how long it takes to dam up again. At present tides are ebb (~3.6m) and there is very little surf so the lagoon may stay open for a while which is really good as each tide flushes out some more pollutants. Tides will peak at about 4.0m over the weekend (should increase the flushing effect) and the surf may remain small for some time yet
