Murky river a con­cern for res­i­dents

- Chris Steel Ecology · Katikati · Bay of Plenty RU

Water in the Ure­tara River, that runs be­hind Katikati town­ship, turned amurky brown colour last Thurs­day con­cern­ing nearby lo­cals.

Katikati res­i­dent Kate Lo­manSmith said it was dis­ap­point­ing to see amas­sive plume of sed­i­ment float­ing down­the Ure­tara river on Thurs­day.

She said a Bay of Plenty Re­gional Coun­cil of­fi­cer spent con­sid­er­able time in­ves­ti­gat­ing the source of this sed­i­ment plume and a po­ten­tial

cause was iden­ti­fied— stream cross­ing works at the Hen­ryRdFord.

Bay of Plenty Re­gional Coun­cil re­ceived two com­plaints over the river’s water dis­coloura­tion and last Thurs­day, aReg­u­la­tory Com­pli­ance Of­fi­cer con­ducted ex­ten­sive area in­quiries along the Ure­tara River from RawakaDriv­e to the Haiku pub­lic re­serve to as­sess water clar­ity and lo­cate the dis­coloura­tion source.

The in­ves­ti­ga­tion iden­ti­fied the Hen­ryRdUre­tara River ford cross­ing as the po­ten­tial source, although the coun­cil is car­ry­ing out fur­ther in­ves­ti­ga­tions to con­firm that.

The re­gional coun­cil has a com­pre­hen­sive, re­gion-wide recreation­al bathing water qual­ity mon­i­tor­ing pro­gramme, which in­cludes the Hen­ryRdFord site on the river.

Sam­ples are col­lected weekly as part of this pro­gramme and re­sults

are up­loaded to theLAWAweb­site.

“The per­ma­nent health warn­ing at Ure­tara re­flects a pat­tern of com­pro­mised water qual­ity dur­ing the­sum­mer­months, andweare in­ves­ti­gat­ing the sit­u­a­tion through our ‘Fo­cus Catch­ments’ pro­gramme,” said en­vi­ron­men­tal water qual­ity sci­en­tist James Dare.

“DNAmeth­ods have iden­ti­fied an avian sig­na­ture as­so­ci­ated with water sam­ples, with ad­di­tion­alDNA ev­i­dence show­ing large num­bers of pu¯keko in the area.”

Kate said dis­cus­sions with par­ties are on­go­ing. i
