I dont know about Pattaya, but here in Phuket they used have a lab in the government hospital that I used some years ago, as for your filter, best to install a Point of Entry filter, I used Zeolite as the media everything works fine,
It's a bit misleading that statement along that road is 2 lanes and a hard shoulder and many bikes do ride in the hard shoulder from the CCTV which is a couple of 100 meters away to me looks like the bike was way over to the left so making her have almost a clear road ahead of her 2 lanes, I live near by there I drove past there this morning, hope she did the right thing #Irina Pustovalova
She should be, she just didn't kill them she wiped them out, when I drive by there I always look across where it happened and see that new electric pole, just few meters before there, there is two other concrete poles holding up one of them transformers, why didn't she hit that?
Still pissed the following morning, it happened a couple of months ago near me, around 8 am, a truck drove into a bike killed both women and the truck driver was pissed, they were all Thai, what happened after that I dont know,
I think she drove them into the electric post, the whole of the area down that main road had no electric for most of the day, from the original CCTV footage you can see sparks flying as it pulled all the cables down, the bike was left there most of the day you could not tell what make of bike it was, a crumpled mess,
She was/is a real estate agent with a office in Rawai, the day after the accident somebody blasted her FB page with the article, she cleared all that out and all of her own photo's, whether she is still operating I dont know, her office is down a soi so I would have to drive down there to see,
