- Washington Oaks is a jewel.

It's an oasis of peace in these stressy days

and when I come here with the family

we are just immediately entering the park and relax

and slow down, which is important.

- It's a totally different experience

because most people, they see Florida

as the beach and theme parks,

but here you have like, the old history of Florida.

You have the nature.

- I take my son and my guests, of course, fishing.

Take the fishing poles out.

We have a little fishing tournament, if possible.

- Here, I mean, if you haven't been here,

there are so many possibilities.

You can go hiking, you can go

take your bike and go through the trails.

It's beautiful because it's really this

typically Floridian nature.

There's a beautiful rose garden they have here.

All the different kinds of exotic trees and plants.

- The Intracoastal is such a nice area anyhow,

but then you find this peaceful, scenic area,

which gives you a total different experience

from other state parks.

- You get some historic points

and they have a little museum.

You can go in and read about it,

so it's very, very interesting.

One of our favorite things to do is to have a picnic.

We bring our coffee and there's so many spots,

you can search out which one every time a new spot.

- Afterwards really just sit down, have a nap.

We'd wake up and then just let the day go by,

whatever we wanna do, read a book.

Just enjoy.

- It's just something very special.

PFAS Sampling in South Washington County - Duration: 7:11.

Hi. I'm Ginny Yingling and I'm a hydrogeologist at the Minnesota

Department of Health.

[music]

Today we're going to be talking about a category of

chemicals called Perfluoroalkyl substances or PFAS. You may have also have

heard them called PFC's. In this video we're going to be talking about why

we're sampling for PFAS, what the sampling process is, where we find PFAS

in southern Washington County and how we decide which private wells to sample. To

see this video again, or to find more information about PFAS, please visit the

Minnesota Department of Health website. Based on the levels of PFAS that we are

finding, there are no immediate health concerns, even if people are using water

that exceeds our current guidance values. The PFAS that we find in Minnesota is

typically well below levels that would pose concerns. Our goal is to lessen the

long term build-up - over many years - in the population of mothers-to-be. For more

information about PFAS health risks, please go to the Minnesota Department of

Health website. We understand people's concerns and their desire to have

answers quickly and that's why we have to focus our sampling in areas where the

evidence shows it is most needed at this time.

PFAS were manufactured in Minnesota. We know where they were disposed of in

South Washington County and we've been studying them since 2003. In light of new

evidence in 2017, the Minnesota Department of Health set new lower

guidance values for two of the PFAS, known as PFOS and PFOA. Again, the

levels of PFOS and PFOA that we find in most of southern Washington County

are not at levels of concern for most people. These new lower values are set to

protect our most sensitive groups. The state of Minnesota has been testing well

water in Washington County to identify any drinking water wells that exceed

these new lower health-based guidance values. We're targeting our investigation

to find wells that exceed these new lower values. That's why we prioritize

our sampling where the available evidence tells us it is most needed. We

determined that based on our understanding of the geology and

groundwater movement and almost 11,000 samples from over 2,700 wells in the

area. The PFAS in Washington County are water soluble which means they can move

quickly through the water. As a result, they quickly left the disposal sites,

entered the groundwater and moved in the direction that the groundwater is

flowing. This resulted in a large area of contamination that we refer to as a

plume. This map shows the location of the PFAS plumes in Washington County. The

blue arrows show the general direction, or gradient, of groundwater flow. South

Washington County sits on a ground water divide between two watersheds and this

controls the direction that groundwater flows. The approximate location of the

ground water divide is shown by this green dashed line. Groundwater on the

west side of the divide flows south-southwest towards the Mississippi

River, while water on the east side of the divide flows east southeast towards

the St. Croix River. Some of the PFAS also got into a surface

water system in Oakdale and Lake Elmo and this allowed them to be carried

across the divide and into parts of West Lakeland Township and northern Afton.

PFBA is another type of PFAS. It's the most soluble and so it doesn't stick

very well to soil or to bedrock and, as a result, it's created the largest area of

contamination shown here in brown. However, health studies suggest that

PFBA has lower toxicity and does not accumulate in our bodies so it has a

much higher health-based guidance value than PFOS or PFOA. In fact, only a

handful of wells very near the disposal sites have levels of PFBA that exceed

its health-based guidance value. PFOA and PFOS are slightly less water soluble

than PFBA and, to a certain degree, they will stick to soil and bedrock and, as a

result, they've created somewhat smaller plumes that are shown here in green for

PFOA and black hash marking for PFOS. You'll notice that those plumes are

elongated in the direction of the groundwater flow. In some places, the

plumes deviate from the groundwater flow because they're following features in

the bedrock, like faults or buried valleys, that channelize the flow of the

water and the contaminants. The white and purple dots on the map show all the

locations where we have sampled since 2003. The purple dots represent the over

880 private drinking water wells that exceeded our new lower health-based

guidance values and where we have issued drinking water advisories. Some areas on

the map don't have very many dots and that's because those areas are served by

city water or, in the case of Afton and Denmark Township, it's because they're

down gradient of areas where we have lots of sampling that show that

concentrations of PFAS are not anywhere near our drinking water guidance

values. Wells that come first for sampling are those that we've never

sampled before and that are located in or down gradient of areas where other

wells have been issued drinking water advisories and have higher levels of

PFOS or PFOA. That's why right now we're focusing our sampling in the areas of

West Lakeland Township and northern most Afton. We're also resampling wells that

have levels of PFOS or PFOA just slightly below our guidance values. As

we're able we're also sampling wells in Cottage Grove and St. Paul Park where

concentrations of PFOA and, to a lesser degree, PFOS are more widely scattered

and the concentrations tend to be lower than in West Lakeland Township and Afton.

Once we've completed that sampling, we'll be able to sample additional wells in

the lower risk area shown in brown. Well owners in the affected community can

request to have their well sampled by filling out an online form on the

Minnesota Department of Health website. Your well will then be placed on a list

and will be sampled in the order of the priority I just described. We'll try to

get it sampled as quickly as we can. You can find out more information about

PFAS at both the Minnesota Department of Health and the Minnesota Pollution

Control Agency web sites. You can also

call the Department of Health at six five one two zero one four eight nine seven.

Andy Murray fights back to enjoy dramatic winning return in Washington - Duration: 5:17.

 Andy Murray secured a battling late-night victory over Mackenzie McDonald on his latest return to competitive tennis and set up a tie with British No

1 Kyle Edmund in Washington.  The three-time Grand Slam champion ended an 11-month absence from the ATP Tour during grass-court events on home soil, but decided his body wasn't ready for best-of-five sets action at Wimbledon

 Instead, he planned to build up his fitness for the US Open, beginning the American hard court summer in Washington

 Murray fully accepts he may not return to top form before 2019 and, in truth, he was nowhere near his best in his first round match at the Citi Open

 At this stage, coming through matches physically unscathed feels like a positive in itself but it speaks volumes to the former world No

1's fighting spirit that he was able to come through this one.  With his own level well below par, Murray made life awkward for his opponent, using all his experience to wear him down on his way to a 3-6 6-4 7-5 win in two hours and 39 minutes

 His reward is a rematch with Edmund, who beat his fellow Briton in Eastbourne.  McDonald is by no means a household name, but entered this match in the form of his life

 He strung three tour-level wins together for the first time in his career to reach the last-16 at Wimbledon, cracking the top-100 in the process

 A graduate from the American college system, the 23-year-old Californian is currently ranked 752 places higher than the British No

21 and his first set performance in particular showed he's capable of climbing far higher

 It was just Murray's third visit to Washington – a tournament where he has enjoyed mixed fortunes – and his first hard court match since March 2017

He will certainly expect better from himself come the end of the summer.  A heavy downpour of rain saw Murray's return delayed, although schedulers' decision to cancel Lukas Lacko's meeting with Denis Kudla – a match which had already started – sped the process along somewhat

 However, it still took more than five hours between the first and final game of Lacko-Kudla and the opening game of Murray-McDonald

 The Scot struck first but showed inevitable signs of rust as he hit back-to-back double faults to gift McDonald the break back

 Confidence grew in the world No. 80 and he reeled off his third game in a row with a thumping forehand winner sealing the break

 Murray pulled out a trademark lob on the run – a shot that has been sorely missed during his lengthy absence – but soon found himself a set down as McDonald broke once more for a 6-3 lead

 McDonald could do no wrong in the back end of the first set, but the winners dried up at the beginning of the second and a couple of erratic swipes handed Murray the break

 As in the first, the Scot let his advantage slip immediately and he let out a roar of pure frustration as McDonald levelled

 Murray hung around in the second set, looking to draw errors from his opponent and he let out a cry of 'let's go!' as he broke for a 5-4 lead before drawing level

 A break at the start of the third seemed to seal McDonald's fate, but he remarkably saved five match points before breaking back for 5-5

 Remarkably, McDonald was penalised by umpire Arnaud Gabas for reaching over the net just a game later and he was broken on the next point, with Murray making no mistake in serving it out this time

 Murray was not the only Brit in action in Washington on Monday, with Katie Boulter involved in the women's singles

 Boulter enjoyed a fabulous win over fifth seed Aleksandra Krunic – a player ranked 71 places higher than her

 The British No. 2 won 6-2 6-0 in little over an hour and will go on to face home favourite Allie Kiick

 Murray's brother Jamie also notched up a win in the doubles along with partner Bruno Soares over Lucas Pouille and Karen Khachanov
