These results show that there were no significant effects noted in the Patea River as a result of the WWTP
discharge. Filtered BOD5 concentration was well within the 2.0 gm2 limit imposed by Special Condition 11, as
was unionised ammonia (NH3). There was one minor exceedance of the limit on turbidity (an increase of
67 %) between the two sites on the March 2017 sampling occasion. This result was indicative of the high
organic wastes’ loadings from the pond,
